Broadcom Corp. has introduced its switch solutions that target the bandwidth, scalability and efficiency demands of next-generation Ethernet aggregation platforms. The StrataXGS delivers up to 40 percent lower power consumption with a huge increase in forwarding scale and flexibility, claimed the company.

According to Broadcom, the StrataXGS BCM56640 series for modular platforms and the StrataXGS BCM56540 series for fixed carrier Ethernet platforms deliver the industry's highest port speeds. The flexible StrataXGS architecture underlying both families is designed for transport-oriented (PTN) and IP-oriented (IP-RAN) aggregation network deployments. They provide operators with greater capacity and service density while controlling operational costs, added the company.

Both StrataXGS series feature the latest Carrier Ethernet innovations including MPLS-TP, MPLS OAM, integrated time synchronization, upgraded protection switching, and extensive IPv4 and IPv6 routing resources.

The BCM56640 series features 240Gbit/s fully-integrated multilayer Carrier Ethernet aggregation switch. It unites 10G serial technology with massive forwarding scale to deliver single-chip line cards from 48xGE up to 100GE. The latest generation has an expandable TCAM interface that offers a platform for up to 1M IPv6 longest-prefix route lookups.

The BCM56540 series has 180Gbit/s fully-integrated multilayer Carrier Ethernet switch. Its flexible port logic allows per-SerDes sharing among GE, 2.5GE and 10GE modes, delivering flexibility for centralized switch silicon system architectures. It also has a forwarding technology that allows providers to allocate lookup resources on a per-application basis, vastly improving the application range of a given system solution, Broadcom noted.

The BCM56640 and BCM56540 are now sampling with production volume slated for 1H12.
