Today Arista announced its entry into the campus market launching several products in the core and aggregation layer for campus switching. For years there has always been a blurry line on how one defines campus core, partially driven by the utility of the Cat 6500 installed base. But this has been changing as the Cat 6500 installed base gets refreshed with purpose built boxes. 

For the most part, when an enterprise has two separate networks for the campus (user connectivity) and data center (server and compute access), campus core is counted in campus.  When campus and data center are one network or the location is smaller the campus core is usually a portion of data center.  This different deployment scenario has caused confusion in the exact size of the campus core market. 

In our research we look at it in both use cases to better understand the too unique use cases as businesses truly look at it differently depending on their networking heritage and IT expertise. 

What is happening now in the campus market is that campus switching is changing. Campus switching is transforming from a user connectivity role to an infrastructure role to support the change is how users connect and to support IoT which started with just cell phones and tablets, but is about to explode.  With campus connectivity changing, so is the core and this is allowing enterprises to rethink their campus core. 

Many customers will continue to see campus as a separate network, but many customers, especially when they are building a hybrid cloud data center are looking at merging the line between server compute and campus connectivity.  We will see this architecture change at the same time the market moves towards MultiGig in the access layer and towards 25 Gbps and 100 Gbps. 

Arris held its annual investor day late last week on March 28, 2018.  It was interesting: the company said "Everything is going wireless," which is an interesting admission for a company that, until about a year ago, was essentially a pureplay on wired broadband.  To be sure, the company has diversified into wireless with its acquisition of Ruckus and has benefitted from the inclusion of Wi-Fi capabilities to its broadband CPE.  The company sees this wireless future - and is pivoting towards it.

Arris management highlighted that it expect its future to include the following growth avenues:

• Cloud Wi-Fi
• DELL OEM
• CBRS 3.5 GHz LTE Small Cell
• IoT (Residential and Industrial)
• FTTx (10Gb EPON / NGPON-2)
• Consumer Mesh Wi-Fi
• Campus Ethernet Switching

Additionally, the company discussed its expectations for each division, which using its 2017 mix and various projections, calculates to a 4.7% CAGR from '17 to '21.

Enterprise Networking (Ruckus).  Overall, the company's Enterprise Networking division, also known as Ruckus Networking, includes its Enterprise WLAN business (formerly Ruckus Wireless), the Brocade ICX Ethernet Switch product line (referred to by the company as Campus Switching), and other revenue streams such as CBRS 3.5 Ghz LTE Small Cells, as well as IoT radio modules that plug into the Ruckus Access Points like Bluetooth, LoRa and Zigbee.  The company is targeting 20%+ growth for the Ruckus Networking group, which is far above the industry growth rates we expect for Enterprise plus Outdoor WLAN and Campus switching. This aggressive growth rate either implies share-taking, or growth in other products such as CBRS, Bluetooth, LoRa and Zigbee, or the the non-WLAN parts of what used to be Ruckus Wireless, such as Cloud-managed Wireless LAN services (that, for instance compete with Cisco's Meraki, Aerohive services and Mojo Networks).  The company cited an expected Enterprise WLAN revenue growth projection slightly above our projection for the period '17 to '21, even if cloud-managed WiFi services were included.

​Network and Cloud Segment.  The company said this market is growing 5% annually, and described the market generally as the Cable Modem Infrastructure, optical nodes and cable video networks market.  The company generally expects to take share, compared to this market viewpoint, projecting a 4-7% long-term annual growth expectation for this business segment.  It was interesting that the company said that the "mobile device explosion [is] driving offload demand," because it has been several years since "Wi-Fi offload" was a growth driver, but dissecting the comment a bit more, the company is pointing to cable operators as being "well positioned to handle [the] offload."  We think Arris' strong supplier position with the major Cable MSOs in the US, especially, may indicate that there should be a strong build up of WiFi and cable infrastructure coming in the future.  And, this corroborates with our own research and statements from MSOs such as Comcast.  In fact, the company showed a "future" network diagram that indicates it expects its MSO customers will be delivering 5G radio, Remote OLTs (PON) and Fixed Wireless Access instead the of cable modem (DOCSIS) equipment that was indicated in the "now" chart.  This implied shift from DOCSIS to PON/5G/FWA would be a dramatic shift in the company's product portfolio.  Very interesting, indeed.

Customer Premises Equipment (CPE) Segment.  The company claims a #1 Set Top Box (STB) market share, and #2 Broadband CPE market share, with a mix of 60% video CPE and 40% broadband revenues in 2017.  The company expects to grow broadband CPE to a mix of 50%+ by the year 2021, consistent with the market growth rates it cites - 4% CAGR for broadband and -.8% for video.  Generally, the company is projecting long term sales trend of -5% to +1%, indicating that it lacks the direct to market exposure that would get it to a growth expectation in this segment.  The company confirmed it is using NBASE-T (Multi-Gigabit Ethernet) interfaces on its home networking devices and it is planning to release 802.11ax capabilities on its portfolio, as well.  Arris CPE will also include Extenders / Adapters to, at least partially, address the growth now occurring in the Consumer Mesh market.
