Software Defined NFV in Google's Cloud Platform

by James E. Carroll

The really exciting phase of cloud computing is just beginning, said Google's Distinguished Engineer Amin Vahdat, speaking at the 22nd Annual Symposium on High Speed Interconnects at Google's HQ in Mountain View, California. It's not about delivering old capabilities cheaper but about new programming models unavailable elsewhere, leveraging low-latency and massive IOPS.

To get there, Vahdat said the old way of networking simply is insufficient to achieve the performance and flexibility needed by next-gen compute and storage systems. Google is leveraging SDN and NFV to run its cloud.

Some key points in his talk:

  • Everything at Google runs on shared infrastructures.  The SDN creates the illusion that individual applications/services are running in their own networks with their own IP address space.
  • Google private backbone, which connects its data centers, is larger and growing faster than its public-facing network. Bandwidth between Google data centers is comparable to what others see inside their data centers.
  • Google has $2.9 billion of additional planned data center builds worldwide.
  • Operating at Google scale reveals that the dominant costs of running a big data center is power and cooling, not the cost of the initial equipment.
  • Google operates a global CDN of edge connectivity with express lanes back to its data centers.
  • Google Andromeda software stack provides the logically centralized SDN control that orchestratew VM, vSwitch, NIC, fabric switch, packet processors and routers.
  • A logically centralized/hierachical control plane with peer to peer data plane beats full decentralization.
  • Baseline NFV is in the fabric. While Google's Andromeda contoller delivers NFV as a cloud service, new APIs will allow 3rd parties to offer additional network services over Google infrastructure.
  • DDoS protection is an essential NFV service. Large companies are under constant attack. The only question is how big is the ongoing attack.
  • Another NFV application is Google Cloud Load Balancing. This can be provisioned in 5 minutes and then takes 4 seconds to ramp. Steady state can be achieved in under 120 seconds. The total cost is $10.
  • Looking at future needs, the challenge is how to spin up a 1,000 port virtual network in a matter of seconds while ensuring isolation, load balancing, external access, bandwidth provisioning and SAN resources. Using Amdahl's lesser known law (1 Mbps of IO for every 1 MHz of computation) and assuming 32-core CPUs supporting lots of VMs, we can see the virtual network will require 100s Tbps of switching capacity.
  • Future NPU must be >2X better than switches and CPUs for the same functionality.
  • Every piece of the system has to be in sync and to achieve this constant auditing is required. You are only as good as weakest link.

Dell'Oro: Packet Microwave Equipment Revenue Grows 50% in 2Q 2014

The Packet Microwave equipment market grew 50 percent year-over-year in the second quarter of 2014, according to a newly published report by Dell'Oro Group.  Ceragon Networks was found to be a beneficiary of the rising demand for packet microwave equipment, as its market share leapt to thirteen percent from just one percent a year ago.

Alcatel-Lucent continued to hold its market-leading position in the second quarter, recording almost half of the Packet Microwave market revenue worldwide.  Ceragon captured the second highest market share; followed by DragonWave.

“This was another fantastic quarter for the packet microwave market,” said Jimmy Yu, Vice President of Microwave Transmission research at Dell’Oro Group. “Interest in packet microwave systems has been steadily rising as operators move towards installing LTE mobile radios.  It’s one of the reasons why the packet microwave market has had four consecutive quarters of year-over-year growth.  Another factor driving the high demand for packet microwave is the rising use of full outdoor units, which carries the advantage of a zero indoor footprint, saving operators both capital and operational expenses,” Yu added.

Infonetics: Strong Sequential Growth for Carrier Routers and Switches

Worldwide service provider router and switch revenue, including IP edge and core routers and carrier Ethernet switches (CES), is up 20% in 2Q14 over 1Q14, to $3.9 billion, according to Infonetics Research. However, Infonetics said the long-term trend is reflected in the decline of 4% from the year-ago quarter (2Q13).

“As we’ve been cautioning, service providers of all sizes are being more guarded with their router spending habits as massive network transformation goals involving software-defined networking (SDN) and network functions virtualization (NFV) translate into specific activities and milestones. But this does not mean router and switch spending will tank or even take a sizeable downturn,” notes Infonetics Research analyst and co-founder Michael Howard.

Continues Howard: “Core router upgrades and replacements prompted by the move to 100GE and paired with many aging core routers drove the core router segment to 11% sequential growth in the second quarter of 2014, and with a lot of capacity ‘in the ground,’ we believe core routers will stay positive for the full year.”

Some highlights:


  • The IP edge router, IP core router, and CES segments all had double-digit revenue gains in 2Q14 from 1Q14
  • On a year-over-year basis, EMEA is the only region to achieve positive revenue growth (+3%) in the carrier router and switch market in 2Q14, while all regions—North America, EMEA, Asia Pacific, and CALA—are up quarter-over-quarter
  • The usual suspects continued to battle it out for the top 4 router and CES market share spots: Cisco stayed in the lead in 2Q14, with Alcatel-Lucent, Huawei, and Juniper (listed in alphabetical order) in a fight for the 2–4 positions
  • Infonetics expects global service provider router and switch revenue to grow at a 2.8% CAGR from 2013 to 2018
