The Barcelona IC for Ethernet network systems is designed especially for enterprise switch and router vendors. Developed by Cortina Systems, Barcelona uses advanced classification, deep buffers, and flexible scheduling to enable increased port counts on switches without compromising on service quality. All of Barcelona’s 24 multirate Ethernet ports support strict service guarantees, which have become increasingly critical in enterprise networks as voice over IP and other new services are deployed.
As voice over IP and other new services become common in enterprise networks, switches must be upgraded to support new performance requirements. Even in a congested network, Barcelona can identify and prioritize critical flows and mark them as high priority with guaranteed bandwidth while storing bulk traffic to prevent packet loss. In addition, with its support for new policing and shaping policies coupled with IPv6 and MPLS functionality, it is also ideal for metro applications where strict service level agreements must be enforced.
Barcelona connects directly to GE optical modules or serially to copper PHYs, and interfaces with existing packet processors through an industry standard SPI port, which makes it ideally suited for Ethernet switches, routers and transport platforms. The IC is implemented in .13 micron CMOS and combines Cortina’s industry-leading expertise in programmable port processing with advanced manufacturing techniques to enhance services in enterprise and service provider networks. Barcelona is currently sampling.
