BCM56450 Series

Mobile Backhaul Ethernet Multilayer Switch and Traffic Manager

The StrataXGS® BCM56450 is Broadcom’s ninth generation of the StrataXGS® product line. The Broadcom StrataXGS BCM56450 is purpose-built for next-generation Carrier Ethernet Edge and Mobile Backhaul platforms. It combines a feature-rich packet processing engine, an integrated hierarchical traffic manager, a deep external packet buffer, and a non-blocking switch fabric into a single 40 nm CMOS device. The StrataXGS BCM56450 supports an integrated packet buffer with an external packet buffer expansion option, utilizing economical DDR3 SDRAM technology. The StrataXGS BCM56450 is capable of handling L2 switching, L3 routing, Metro VPN tunneling, and Access Control Lists (ACLs). The StrataXGS BCM56450’s virtualized architecture enables seamless support for VPLS, VPWS, MPLS-TP, PBB, and PBB-TE tunneling.

The StrataXGS BCM56450 also offers unparalleled integration for supporting Ethernet time synchronization. Synchronous Ethernet Clock recovery is supported on any port to enable physical layer clock synchronization. In addition to physical layer clock synchronization, the StrataXGS BCM56450 supports both IEEE 1588v2 and IEEE 802.1as packet-based clock synchronization.
