SAI Speeds XPliant Switch Deployment

20 August 2015

Cavium, Inc. has announced that Microsoft Azure Networking has ported its L3 Border Gateway Protocol (BGP) routing stack to Cavium’s XPliant switches using the Switch Abstraction Interface (SAI). The result is portability and interoperability across diverse hardware platforms.

Previously, proprietary software interfaces created by switch silicon vendors needed extensive porting efforts by customers to create an end-user switch product. The Switch Abstraction Interface (SAI) was defined as an abstraction interface for switching ASICs in order to remove the barriers of a proprietary lock-in for legacy software.

However, SAI enables system developers to quickly and easily port software to the best choice in switch silicon that supports these SAI abstractions. Earlier this year, Cavium announced SAI support in the XPliant switch SDK (software development kit) and now released this software for general availability. Microsoft has easily ported Layer 3 BGP routing applications to the XPliant switch SDK based on the SAI interface. This software is currently running on the XPliant based Edge Core AS7500-32X switch and is being demonstrated at the SIGCOMM 2015 event, held August 17-21 in London.

The Cavium XPliant Ethernet switch family targets applications in cloud /enterprise data centers and service provider infrastructure, for top-of-rack and backbone applications. The highly configurable Ethernet switches with bandwidths up to 3.2 Terabits per second in monolithic silicon support 1G, 10G, 25G, 40G, 50G and 100G interfaces. This family of switches will also provide connectivity solutions for embedded applications.

Microsoft’s L3 software running on the Edge Core AS7500-32X switch powered by Cavium’s XPliant switching silicon will be demonstrated during the Industrial demo session on Thursday August 20 at SIGCOMM 2015.
