Brooklyn-10 Carrier Ethernet Switch

While existing NPU solutions require significant programming investments, deliver non-deterministic performance, have high power consumption and result in lengthy times to market, the Brooklyn-10 Carrier Ethernet Switch delivers efficient and intelligent performance without the need for data path programming.

Carrier business models are built on delivering circuits, and the Brooklyn-10 integrates new Ethernet capabilities in switching silicon. It supports Provider Edge Bridging (PEB), Provider Backbone Bridging (PBB), PBB-Traffic Engineering (PBB-TE) and Transport Multi-Protocol Label Switching (T-MPLS). The Brooklyn-10 is a standards-based solution, purpose-built to allow network equipment providers to enable next-generation carrier Ethernet services.

Support for Current and Emerging Industry Standards

802.1qVLAN — Virtual LAN tagging
802.1adPB —Provider Bridges (Q-in-Q)
802.1ahPBB—Provider Backbone Bridge (MAC-in-MAC)
802.1agCFM—Connectivity Fault Management
802.1QayPBB-TE—Provider Backbone Bridge—Traffic Engineering
RFC-4762VPLS—Multipoint-to-multipoint E-LAN Service
RFC-4026VPWS—Point-to-point E-LINE Service
H-VPLS—Hierarchical Virtual Private LAN Service

The Brooklyn-10 is a flexible and highly integrated 20Gb switching device supporting Layer 2 VPN services across the metro and wide area network. Services are supported directly on the native transport or as layered services over packet switched networks. It provides comprehensive traffic management support and the Brooklyn-10 switches traffic between ten 1Gb Ethernet client ports and a single 20Gb SPI4.2 network port. Multiple Brooklyn-10 devices can be interconnected to enable a wide range of system and line card configurations.

Features & Benefits

    Carrier Scalability
  • 20G non-blocking architecture
  • 10 x 1 GbE client ports and 1x 10Gb network port
  • Scalable external memory to expand number of lookup table entries and the depth of packet buffering
  • Up to 128K MAC addresses
  • Up to 16K pseudowires
  • 4K VLANs per port
    Quality of Service
  • Classification: Derives traffic type which determines the latency/priority of a packet
  • Traffic Policing: Monitors rate against agreed levels and marks packet as drop-eligible accordingly
  • Congestion Avoidance: Drop-eligible packets can be discarded if congestion occurs
  • Queuing: Queues the packet to data memory and its associated control entry to control memory
  • Scheduling: Selects a queue to read and transmit a frame
    Operations, Administration and Management (OAM)
  • Supports both Service and Link Layer OAM standards
  • On-chip hardware support for CFM filtering (802.1ag)
  • CFM filter functionality provides flexibility and configurability
  • Filtering functions based on CFM-MA-LEVEL and CFM_OPCODE addressed table
    Protection and Statistics
  • An extensive set of statistics counters to monitor performance and operation
  • Statistics counters integrated via internal RAM for real-time feedback
  • Extraction of statistical information either through DMA or programmed I/O
  • Multiple protection methods supported including the sharing 802.11Q VLAN traffic over multiple physical paths using RSTP/MSTP
