On August 8, 2019, publicly-traded Cambium announced that it had completed the acquisition of the Xirrus products and cloud services from privately-held Riverbed Technology, Inc.  Xirrus has been a vendor in the Enterprise WLAN market for a while now and has been associated with its high-performance enterprise-class WLAN products as well as its cloud-managed services.  In our research, we find Xirrus has done well in the large venues, the education, government, and retail markets.

We interviewed the team at Cambium today and learned that the company is committed to using channels as a distribution strategy for the combined portfolio.  Additionally, the team told us it will be supporting both Cambium WLAN customers as well as Xirrus customers, and that, over time, the products and services will be converged.  We think it makes sense to rationalize the products, which will allow future customers to take advantage of developments made at each of the organizations.  The team explained that Cambium will be focusing primarily on medium and small-sized customers and that it will not be pursuing large enterprises associated with the Fortune 1000, instance.

The timing of Cambium’s acquisition makes sense on several counts.  First, it just completed its Initial Public Offering and is more well-capitalized than when it was a privately-held company. Second, during its IPO, Cambium identified that it expects its exposure to the enterprise market is key to its growth, so getting more exposure here will increase it further.  Third, several other companies have acquired enterprise WLAN vendors, and Cambium is part of this greater trend.  For instance, Arista Networks completed its acquisition of Mojo Networks in late 2018 and Juniper Networks closed its acquisition of Mist Systems at the end of 1Q19.

Huawei had record European revenue in 2Q19 for the Ethernet Switch market. 

Both Data Center Switching and Campus Switching showed strong performance in Europe in the quarter despite the ongoing trade war.  On an overall basis, Huawei’s Ethernet Switch results were flat Y/Y.  China results for the company were down slightly Y/Y, but we note significant competition in China from local companies like H3C, Ruijie, Sundray, as well as several others.
 
With over a dozen vendors reporting results already, Europe has performed inconsistently.  A little more half of the vendors grew Y/Y while the rest had Y/Y declines.  While we expect Europe to fluctuate, especially with vendors have unique country and deal exposure, the results are unique and imply interesting share results for the region when we publish the 2Q19 report. 

Today, Huawei announced 1H19 results were CNY401.3B, up 23.2% Y/Y.  Carrier business 1H19 revenues were CNY146.5B, with 50 commercial 5G contracts and shipments of more than 150,000 base stations.  Enterprise 1H19 revenues were CNY31.6B.  Consumer Business 1H19 revenues were CNY220.8B, with 118M smartphone units, up 24% Y/Y.  The company said "revenue grew fast up through May.  [and that] we continue to see growth even after we were added to the entity list."

The fact that Huawei says it is still experiencing growth despite being placed on the US Entity List is important because it says that despite the efforts of the US to stymie Huawei, it is still growing.  Huawei has typically provided semi-annual results to the public, so it is not odd that has not provided 2Q19 results, which were almost certainly weaker than 1Q19 results given the US efforts to slow Huawei.
​

Extreme Networks announced plans to acquire Aerohive, which has most of its revenues in Enterprise WLAN.  The deal was a surprise, as evidenced by the 40% price premium paid on on HIVE.  After this deal closes, Extreme's WLAN business will be the combination of three WLAN businesses - the traditional WLAN business from Enterasys (Ottawa based team), the Motorola Wireless WLAN business (acquired by Zebra, then sold to Extreme) and Aerohive.  Each of these three businesses had strengths, for instance, the Ottawa team had designed a product line that had high performance in crowded venues - Extreme has enjoyed a long relationship with the NFV; the Motorola team had designed systems that were effective in retail and logistics (as a consequence of Motorola's ownership of Symbol Tech, a bar code scanner company); and Aerohive, which was as of 1Q19 the #2 revenue player in cloud-managed WLAN services and with a strong presence in the US K-12 vertical.  While there is certainly some risk that Extreme does not integrate the Aerohive business effectively, there are some interesting aspects to this deal.
#1: Aerohive's cloud-managed WLAN services is a significant player in the market.  We expect many small and medium businesses will adopt cloud-managed WLAN, and Extreme had a less mature offering here.  We see this as the primary benefit of the Aerohive acquisition.
#2: Aerohive's vertical market exposure in US K-12 (education) market and the managed care part of the health care industry are a nice addition to Extreme.  These markets are additive.
#3: Aerohive had a SD-WAN product that while not a big revenue generator will be important for Extreme in selling to small and medium sized businesses.  We expect the SMEs and branch offices will be upgrading using a SD-Branch approach, where upgrades to WLAN, switching and SD-WAN will be done at once.  Extreme had a hole here and Aerohive fills it.
#4: Aerohive had a new product, A3, which we categorized as Enhanced Network Access Control.  The front end of this product is very modern.  Extreme also had its own NAC product.  Our hunch is the company will merge the two, taking the best of both.  We see larger enterprises as demanding this type of support.  HPE Aruba sells its Clearpass product in a wireless+wired+ENAC bundle to larger sized business, just as Cisco sells its ISE and wireless+wired bundle.  
#5: Aerohive has 802.11ax products.  We expect that increasingly, as customers adopt 802.11ax, with its expected throughput under high loads exceeding 1 Gb/sec, this will drive an upgrade cycle to switches with MultiGigabit support.  Extreme cited "cross selling" in its announcement of this deal, and we agree that customers in the 802.11ax world will be increasingly buying new switches when they adopt new wireless.

This deal was a surprise because Extreme already has WLAN in its portfolio, but if Extreme executes on this business transaction effectively, it can solidify its position in the mid-market by offering cloud services and SD-WAN (through a SD-Branch bundle) and potentially move both up market (with ENAC) and if it choses, downmarket by maintaining a business practice that Aerohive rolled out well over a year ago that can be described as a "freemium" model for its cloud-managed WLAN services.

MACSec Helps Pave the Way to End-to-End Data Security

As consumers and businesses put more data in the Cloud, the importance of securing that data increases.  In just the last year, we have seen advanced threats and attacks by various entities to hack into that data and hyperscalers push back with both public and private mechanisms. Securing that data goes beyond just basic encryption or securing a server, and the role of the network is critical to better protection of data.

Many cloud customers are looking at providing end-to-end security to ensure, as best they can, that data can not be compromised.  MACSec plays an important role in the future on how networks talk to each other and how the secure transmission of data between different locations.  Security is especially important with 400 Gbps, as Cloud providers adopt 400 Gbps, it is not only being used for transmission within the data center but also Data Center Interconnect (DCI).  Cloud workloads will increasingly require secure connectivity between data centers.

Looking at the Ethernet Switch and Router markets, we project the percent of ports shipping with MACSec will increase significantly over our forecast horizon.  We expect vendors will continue to offer versions with and without MACSec, but as we move forward in time and have more purpose-built offerings for the hyperscalers that some products will only ship with MACSec.

The additional features and functionality included in Ethernet switches and Routers are positive for the industry.  It not only increases features which help grow ASPs and revenues, but it also increases the amount of Ethernet ports shipped by expanding the number of use cases.  400 Gbps DCI is a great example of feature and addressable market expansion.

Mellanox and Arista May Announcements

New Switches & Routers Spell New Possibilities 

The hyperscale, cloud and hyper converged industry — despite a pause in data center equipment growth in Q1, as we reported last week—  saw two major Ethernet product announcements so far this month. 
 
Both new platforms, announced by Mellanox and Arista respectively, are supercharged to take the data center to the next level. They play into all of the big trends of cloud hosted, mass virtualization and automation of trouble shooting through telemetry.  They also seem to set some new performance records.




Details: 
First there is Mellanox, unveiling this week its “Ethernet Cloud Fabric” (aka ECF) new switches underpinned by its  Spectrum2 chipset. Mellanox is emphasizing automated troubleshooting with telemetry, support of virtualization, scale to 400GbE, and a fully shared buffer architecture for improved performance in hyper scale cloud environments.

Mellanox ECF Platform Highlights:

• Mellanox “What Just Happened” (WJH) Telemetry: Offers improved visibility as to the root cause of network/server problems while reducing the amount of telemetry data that needs to be stored.
• Spectrum2 chipset, developed in house, has a fully shared buffer architecture for better microburst absorption. The new switches fairly and predictably divide traffic between servers. 
  • Fairness is an issue for ESF and ECF use cases.  It is found in Hadoop, CEPH, and SAP environments. This is where fair and predictable performance matters. 
  •  For ECF in clouds. You have to stop one tenant from robbing resources of others, whereas neighboring tenants might get robbed of another performance. 
• Virtualization:  Mellanox makes better spine switches with increased visibility, performance and virtualization support of VXLANs.   
• 200 Gigabit: The 200GbE switches will be useful for high speed applications like Machine Learning and NVMEoF.  
• 200GbE will also be deployed in volume by hyperscaler / social media companies. Some large customers prefer 200G over 400G for the larger radix as it can eliminate a switching tier in a large data center

ECF Performance:

• 8.33 Billion Packets per second 
• 42MB Monolithic and fully shared packet buffer to provide high bandwidth and low-latency cut-through performance
• Robust RoCE Datapath to enable hardware accelerated data movement for Ethernet Storage Fabric and Machine Learning applications
• Half a million flexible forwarding entries to support large Layer-2 and Layer-3 networks

Next is the announcement from stalwart cloud player Arista, and it has delivered its own new products, its' R3 Series routing platforms. The emphasis is on massive throughput, density, power efficiency and price performance. 



R3 Platform Highlights

• Throughput: Packet processing offers 8X the throughput of the previous generation R1 Series and 5X the throughput of the R2 Series. 
• 400G Ethernet: high-density 400G ports across all platforms to support these next-generation networks.
• New Capabilities: New R3 packet processing silicon offers significant enhancements in route scale, security and telemetry. .
• Wide Range of Form Factors: The new R3 Series comes in a wide range of form factors, including four fixed form factors, an upgrade to our award winning 7500 family, and the brand new 7800 modular chassis with up to 460 Tbps capacity per chassis

Key Capabilities 

• The Arista 7280R3 delivers unparalleled Performance with Dynamic Deep Buffers and VOQ for Lossless forwarding
• Flexible design choices for 10G/25G/40G/50G/100G and 400G
• FlexRoute™ and EOS NetDB™ for internet peering with high density and low power
• Embedded Accelerated sFlow and IPFIX for high capacity network security and application monitoring
• Flexible pipeline for programmable features including Algorithmic ACLs and Inband Network Telemetry for flow and packet forensic

We attended the Open19 Foundation Summit 2019 in San Jose, CA.  The key message of the leadership team of the Foundation was that it expects 2019 to be the year where Open19 systems begin shipping.  Yuval Bachar, President of the Foundation explained that there are 8-10 companies that are deploying or seriously considering, including two mega data center operators in process of evaluation and at least 6 adopters in advanced evaluation/deployment.  Open19 does not specify what technology will be inside the systems; it only defines the form factor.  Interestingly, GPU and ARM designs are included and we heard about AMD CPU more often than we did Intel.  
 
VaporIO made a presentation about its edge data center systems.  Matt Trifiro, CMO of VaporIO explained that its systems nominally consume up to 165 kw in a 9 foot round datacenter.  It claims that Vapor IO is deploying in 6 cities, 3 to 4 data centers in each city.

ASUS and a new company, German Edge Cloud, both made interesting presentations.  Salim Fedel, Associate VP Enterprise Solutions Business Group, ASUS, presented a few of the company's Open19 oriented products, Alps19, Brick and its Network Switch.  Jason Rylands, VP of Data Center Strategy & International Sales, German Edge Cloud, made a very interesting presentation about its company's activities in Germany on how it is participating in the manufacturing industry in Germany.  There is reticence on putting manufacturing data and control on the cloud, but there is a desire to build a German-only computing system, driven in part by GDPR and part by the nation's focus on manufacturing - that's the opportunity.  German Edge Cloud has decided to use Open19 systems - accessing only the front of the racks is a big deal, it believes.

German Edge Cloud shared many examples of how it is engaging with manufacturers for real-time error tracking during the manufacturing process, using analytics, and sharing information between various companies in the German supply chain.

​We attended media briefings at the Keysight World conference held near San Francisco, California, yesterday.  Keysight World San Francisco showed a more integrated Ixia as well as a further push towards 5G, automotive and energy, and data center and telecom.  Much of the companies conversations during the event related to synergies between these technologies.  Such as how to push the automotive industry forward using 5G and the need for edge computing in 5G.  As Keysight is involved at the beginning of the launches of many new cellular technologies, it has good insights into the timeline and progress of the 5G market.

One of our key takeaways from the show is the increased pervasiveness of Ethernet in the telecom and automotive industry as well as the significant increase in constant data creation.  All this data will need robust, and more intelligent networks to transport it.  We were also impressed that Keysight World will actually take place in 10 cities around the world, with San Francisco being the first.

Another interesting observation was just how global Keysight was in looking at products, for example in one session that we attended, much of the automotive effort in the company was located in Germany.

According to news reports and press and social media announcements by high-ranking members of US government, the US government has put Huawei on its so-called "Entity List" of the Bureau of Industry and Security (BIS).  Our read on this is it similar to what happened with ZTE during C2Q18 last year, a move that severely curtailed ZTE's shipments and revenue until ZTE made concessions and was removed from the list.  Many, but not all, Huawei products use technology only available from US suppliers. US-made semiconductors are the most significant Entity List target that Huawei needs to ship its products.  Significant US semiconductor suppliers to Huawei include Intel, Xilinx, and Broadcom.  

Huawei is such a significant vendor in many of our coverage areas, including Mobile Radio Access Networks (RAN), Ethernet Switching, and Servers, for instance, that we feel it is a good time to point out that 2019 market-level estimates may be at risk.  Additionally, since Chinese cloud services players, like Baidu, Alibaba and Tencent cannot delay their capital infrastructure build-outs, alternate suppliers may benefit.

We think it comes as no surprise to Huawei that the US is putting it under pressure.  Just over a year ago, we attended the Huawei analyst summit (April 16, 2018) and its then-chairman said in response to the question "Will Huawei find alternate suppliers for data center products, "Today, Intel is the dominant player.  Our point of view, we look forward to a more diversified landscape; but we work with Intel mainly now."  Additionally, at Huawei's most recent analyst summit (mid-April 2019), the three main keynote speakers, all high-ranking executives of the company spoke about how much progress Huawei has made in developing in-house semiconductors and what its plans are to continue developing more.  We do, however, think that despite Huawei's diversification efforts that it still has significant reliance upon key US chip companies.

The main message of Ribbon keynotes was that Ribbon has moved from a voice and SBC focus to a broader scope including data and analytics, such as UCaaS, Security-as-a-Service, Service Assurance-as-a-Service, SIP Trunking-as-a-Service, SD-WAN, and analytics.  The company identified two major catalysts to the change in company scope: the August 2018 acquisition of enterprise SBC company Edgewater and the February 2019 acquisition of analytics company, anova. Additionally, the company confirmed that it is not pursuing service provider mobile market opportunities such as EPC or “full IMS” that are components of larget mobile equipment larger vendors.  Instead, Ribbon is pursuing the mobile market by offering overlay analytics services that allow SP customers to derive value from mobile operators using monetization, network, marketing, and customer care.  

The company’s core business is evolving.  For instance, the company has doubled down on the Enterprise market with its Edgewater acquisition, and a result, it emphasized that it is unique because it has both service provider and enterprise SBC product offerings.  The company has offered SBC on public cloud and reiterated that this capability has been available for one year.  The company highlighted that it has a Tier-1 Mobile Network Operator VoLTE Interconnect contract win. 

Analytics.  The company sees its opportunity in the analytics market is to deliver technology to the customer for the following cases:
•             Monetization (Targeting, Advertising, Sponsored Data, Campaign Efficacy)
•             Network (Reduce Network Cost, Improved Quality of Experience, Proactive Alarms, Network Service Assurance)
•             Marketing (Service bundles, churn reduction, product insights, inferred demographics)
•             Customer Care (customer experience, bill shock, most probably cause)

We are impressed with Ribbon’s technical capabilities when it comes to using GPUs.  The company has previously discussed the performance of its GPU based media interworking function as being 3.5x more powerful than a DSP-based system, or 9x more powerful than a CPU-based system and over 2x more power efficient.  The company says its GPU-based systems are generally available for its D-SBC and i-SBC functions.  It has evaluations at three operators: Tier-1 US MNO, Tier-1 US CSP, and Tier-1 Japan CSP.  We would not be surprised if some of these customers begin deploying soon.  One of its Tier-1 operators found that the GPU-based system costs half as much in capital spending and is 800% more power efficient. 

​Kandy, the white-label voice/messaging services brand of Ribbon discussed its success with customers such as BT, NUWAVE, AT&T, Hong Kong Broadband, Optus, and ecosystem partner, Five9.  It enables UCaaS, CPaaS and WebRTC services.  The company reiterated that it plans to go to market with partners, mainly service providers, instead of opening its own store-front that would compete with service providers.  The company says its customer pipeline is growing.
