LSI Corp. has launched its next-generation link communication processor (LCP) designed to allow migration of network traffic to IP-based networks. The LCP is a significant addition to the LSI family of multiservice processors and a key part of the LSI asymmetric multicore processor portfolio that enables any-to-any communications in wireless infrastructure.

An asymmetrical multicore SoC supports all major protocols, enabling wireless, mobile backhaul, multiservice, router and broadband access traffic to be easily and efficiently migrated from current-generation, TDM networks to next-generation Ethernet and multiprotocol label switching (MPLS) networks at much lower cost and risk than previous solutions.

The LCP performs multiprotocol processing at wire speed using dedicated, on-chip programmable cores. It contains multicore ARM processors for managing data plane applications, and running customer-specific application code. Connectivity is provided by integrated gigabit Ethernet interfaces, enabling direct WAN uplinks. In addition, the LCP scales across a broad range of network speeds, from T1/E1 to STM-1/OC-3, which allows networking OEMs to leverage a single development effort across all major services and performance levels.

"The complex mix of protocols and applications that run on today's advanced networks require highly integrated, multicore SoCs with proven software," said Shane Gunning, multiservice marketing director, networking components division, LSI. "Our latest-generation LCP provides OEMs with a single, scalable, highly efficient platform that enables them to build multiservice base stations and controllers that span 2G, 3G and 4G networks."

In wireless applications, the LCP SoC supports backhaul of BTS (2G) and Node B (3G) traffic to BSC (2G) and RNC (3G) controllers. Similarly, the new multicore LCP enables the transport of multiple standard protocols across wireline packet networks. The LCP continues to operate in the event of a planned or unplanned system reboot, and, because of its unique protection switching and warm restart features, it can minimize network downtime due to system or card failure.
