Ethernet Silicon Purpose-Built for the Carrier Market

Carrier Ethernet Switches

Service providers continue to develop next-generation IP networks that require carrier Ethernet switches and routers. Unlike enterprise platforms, carrier Ethernet switches need to:

Scale to support tens-of-thousands of subscribers
Provide secure/private connection-oriented services
Offer robust per subscriber QoS
Provide the protection and self-healing qualities of the existing SONET/SDH infrastructure

As the volumes of carrier Ethernet solutions increase, the current method for providing these capabilities via expensive and time-consuming NPU and/or FPGA-based solutions will no longer meet the time-to-market and cost pressures of the market.

The Brooklyn-10 Carrier Ethernet Switch is a highly integrated, cost effective, Layer 2+ device purpose-built for carrier Ethernet applications. To provide deterministic provider bridge network scaling, flexible flow multiplexing using S-tag (Q-in-Q) and B-tag (MAC-in-MAC ) protocols is integrated in hardware.

The Brooklyn-10 scales to up to 128K MAC addresses for supporting the MAC-in-MAC protocol and the emerging PBB-TE standard. If a system is being deployed within a MPLS network, the Brooklyn-10 provides the necessary VPLS, VPWS and H-VPLS Layer 2 support with up to 16K pseudowires. Next-generation carrier Ethernet switches based on the Brooklyn-10 will have the flexibility to be:

Deployed in different networks (PEB, PBB, PBB-TE, MPLS)
Meet stringent Ethernet Service Level Agreements (SLAs)
Provide the protection that service providers demand
