LSI unveils new link communication processor for wireless networks

Multiprotocol support and mobile backhaul in a system on a chip

By CBR Staff Writer

LSI has unveiled a new link communication processor (LCP) designed to allow migration of network traffic to IP-based networks.

The LCP is an addition to the company’s family of multiservice processors and a part of asymmetric multicore processor portfolio that enables any-to-any communications in wireless infrastructure.

According to LSI, the new LCP is a asymmetrical multicore system on a chip (SoC) that is based on the link layer processor. It supports major protocols, enabling wireless, mobile backhaul, multiservice, router and broadband access traffic to be migrated from current-generation, time-division multiplexing (TDM) networks to NxG ethernet and multiprotocol label switching (MPLS) networks.

The company said that 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 wide area network (WAN) uplinks.

In addition, the LCP scales across a range of network speeds from T1/E1 to STM-1/OC-3 and enables the transport of multiple standard protocols across wireline packet networks. It continues to operate in the event of a planned or unplanned system reboot, and because of its protection switching and warm restart features, it can minimise network downtime due to system or card failure, the company said.

Shane Gunning, multiservice marketing director for networking components division at LSI,said: The complex mix of protocols and applications that run on today’s advanced networks require highly integrated, multicore SoCs with proven software. 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.
