LSI Unveils its Next Gen Traffic Management for Carrier Ethernet

LSI announced Ethernet Functional Programming Interface (FPI) Release 3.0, its next-generation, traffic management software for carrier-class Ethernet transport. The release offers a new suite of scalable features and functions developed expressly for carrier-class Ethernet networks, including wireless backhaul management tools for service classification, reliability and quality of service.


The new FPI leverages a single interface across the full range of LSI APP multicore processors, enabling OEMs to utilize a single application across a broad system portfolio, reducing up-front R&D investment. The LSI APP platform is comprised of a multicore general-purpose processor and specialized programmable cores which provide packet processing, traffic management and security functions. Specifically, LSI Ethernet FPI 3.0 offersOAM (operations, administration and maintenance) and CFM (connectivity fault management) functions, and contains a programmable toolkit that enables wireless service providers to provision guaranteed service levels, improve network reliability and significantly reduce operating costs. Performance monitoring, link detection and network diagnostics are accelerated on the LSI communications processor. Because the bulk of OAM processing is offloaded from the host, system performance is increased and overall costs are also reduced.


LSI noted that its Ethernet FPI 3.0 also provides support for Internet protocol security (IPsec) encryption, decryption and public key acceleration. Because true and pseudo random number generators are generated by the security engine embedded in the LSI communications processor, security processing occurs without intervention from the host.



The software supports provider backbone bridging and transport applications, along with ITU-T G.8031 and G.8032 compliant automatic Ethernet protection switching. In addition, the FPI is compliant with MEF industry standards 6.1, 10.1 and 14, and IEEE(R) 802.1ag, IEEE 802.3ah and ITU-T Y.1731. LSI has demonstrated IEEE 1588v2 protocol stack integration on its APP3300 platform.
