Keynotes at the NFV World & Zero-Touch Congress in San Jose, California were very interesting today. We share our observations and view of the main themes from these interesting presentations by Nokia, NEC/Netcracker, Google, CenturyTel. The main theme of these presentations, we think, is this: NFV/SDN is now deeply in the deployment and commercial phase, where compared to 3-4 years ago, it was just a concept.
Nokia. The company announced that its Airframe server platform, which is an OCP based design, comes available with either embedded acceleration or pluggable acceleration. This comment includes its software acceleration. The company explained that its Reefshark chipset can be equipped on the Airframe server and can perform better than a non-accelerated server:
In explaining functions that an Airframe with Reefshark can perform, the company gave a good example: massive MIMO beamforming can be assisted by the machine learning capabilities.
NEC/Netcracker. Enrique Gracia presented several uses cases of the NEC/Netcracker customers that related to NFV/SDN. He explained that 16 customers have deployed one or more of these uses cases.
Full Stack OSS/BSS/MANO. A customer deployed this system in 12 weeks to launch a VNF. The system managed both physical and virtual devices.
Expand to a new territory using VNFs from home region. A customer now delivers services to a customer outside the home territory by deploying the software and service from the network location at the home location. In this particular case, NEC/Netcracker and its customer do revenue sharing and VNFs include SD-WAN, virtual firewall and others. The service provider is expected to expand its customer addressable base by 40%, mainly targeting small/medium businesses in this non-home region. This system uses MANO, OSS, BSS and the marketplace. The company says in this case, time to revenue is expected to take 50% less time to deploy new VNFs in the future.
uCPE (Universal Customer Premises Equipment) deployment instead of branded hardware. The company worked with a service provider company to enable uCPE to be deployed as an alternative to Cisco, Juniper and others' gear.
Google Cloud. Vijoy Pandey, who represented Google Cloud, presented on the topic of using AI/ML to reconfigure its data center system. The company's cloud data center architecture has been evolving continuously since it was first introduced. Currently, the company is using its own AI/ML system to learn from current network traffic patterns in order to design its future network architecture.
CenturyTel. The company has deployed Broadcom based Ethernet switches using its own Network OS. These switches do their own packet forwarding. Additionally, the company has built its own orchestration system called VICTOR. It draws upon Ansible, NetCONF, uses the service logic interpreter from ONAP and uses parts of Open Daylight. The company plans to open source this development and the spokesperson Adam Dunstan said, perhaps jokingly, that this might be called ONAP-lite.
We attended the #OFC18 show and found the major theme to be the emergence of 400 Gbps modules. The next most noteworthy theme, we though, was that made by a single company, Nokia, which made its PSE-3 engine announcement. Juniper also caused a buzz with the introduction of its ACX6360 router/packet optical product announcement (paired with other announcements, too). There were countless other announcements at the show that we will touch on in our reports, but these struck us a quite noteworthy.
400 Gbps optical modules, generally, are expected to be ready for sampling in the next couple months, and then be ready for volume shipments in 1H19. Most every module vendor is planning to introduce DD-QSFP. A subset of the same vendors was demonstrating OSFP modules, suggesting it was less popular at this time. We recognized a sub-theme of the 400 Gbps theme was that vendors, including Cisco and Juniper were both demonstrating hardware designs that are capable of operating at 15 Watts, which appears to be the heat that will be generated for some of the 400 Gbps modules. At the time of the show, module companies reported to us that the DSPs that would power 400 Gbps modules were unavailable, and the way it was represented to us on multiple occassions was that there is no clear indication which DSP maker would introduce the first working part.
Nokia made its PSE-3 chip announcement in support of its Optical Transport product line. It was standing room only, with lots of customers involved in the presentation (not just a bunch of analysts and competitors). We were impressed with the marketing aspect of this announcement, but also with the the statement, "we have reached the economic Shannon's limit" with the introduction of the PSE-3 engine. The implication of economic Shannon's limit is that to achieve an even more efficient design that would asymptote even closer to the theoretical Shannon's limit would be too costly. The company is claiming 25% improvement in capacity and reach, 70% increased network capacity, 60% reduction in power per bit. Chungwa Telecom and Facebook were live, on stage, serving as references for Nokia's launch. We expect full fledged PSE-3 based products will be available in about 9-12 months based on discussions at the show.
Juniper announced its ACX6360 system (as well the announcement of the ACX5448 Universal Metro Router and the PTX10002 Packet Transport Router). The ACX6360 can operate as a packet optical device, and with a software update, can also operate as a router. The general idea behind the introduction of this product is it can serve in either the packet optical transport role or as a IP/MPLS router, thereby collapsing multiple networking layers into a single platform operating at speeds up to 200 Gbps. For many uses cases, it could reduce the number of boxes from two (packet optical plus router) to one (ACX6360).
New CTO - It was great to see and hear Juniper’s new CTO, Bikash Koley at NXTWORK. The message was very clear that new networks need to be built, not only from the speeds and feeds technology point of view, but from the operator point of view. Scale and simplicity are very important and only going to be more critical as billions of IoT devices dump traffic and data on the network. Juniper is looking to take the network it is building for some of the hyperscalers and Service providers and take help the tier 2/3 Cloud as well as the enterprise customer adopt a cloud architecture for the future.
Contrail – The big announcement was OpenContrail joining the Linux foundation. What we saw in talking to customers and listening to the talks was that Contrail has significant commercial adoption, definitely larger than perceived in the marketplace. We see the largest hyperscalers and service providers as having their own controllers, but see Juniper leveraging its expertise in this area into smaller Cloud and service providers. This will give Juniper the opportunity to build, operate, and transfer for many customers.
We were impressed with the caliber of customers that Juniper has. Juniper has premier Cloud, Service Provider, and Enterprise customers. We enjoyed listening to Twitter’s VP of engineering on stage as an example. We see Juniper as one of just a handful of vendors that can support a customer base with this breath and complexity. We note Juniper mentioned complexity and simplicity throughout the sessions; we only see networking getting more complex, especially as we move beyond 100 Gbps. It is up to vendors to help the human scale with that complexity and we saw Juniper give many good examples during NXTWORK 2017.
