Brocade Communications Systems 8000, 4000 Brocade Netiron Xmr Series At A Glance, Advanced QoS

KEY FEATURES CONTINUED

Rapid link/node failure detection with advanced traffic protection:

•BFD for rapid detection of neighbor/adjacency failure

•Brocade UDLD and IEEE LFS for fast detection of link problems

•MPLS FRR and Hot Standby paths for traffic protection

•Distributed, scalable, wire-speed tunneling for IPv4 over GRE, and IPv6 over IPv4

Industry leading 320 Gbps link aggregation capability for aggregating up to 32 10GbE/OC-192 links in provider backbones

Advanced QoS:

•Eight distinct priority levels

•Weighted Random Early Discard (WRED) support for congestion management and precedence dropping (tunable via configuration)

•Support for hybrid queue servicing disciplines: Strict Priority + Weighted Fair Queuing

State-of-the-art policy enforcement and monitoring for enforcing SLAs and implementing security policies:

•Two rate three color traffic policers

•Traffic policer accounting

•Layer 3 and Layer 2 ACLs

•Granular ACL accounting

•Hardware-based packet filtering

•Hardware-based policy based routing (PBR)

•Unicast Reverse Path Forwarding (uRPF)

•Receive ACLs

•Extensive sFlow Layer 2-7 traffic monitoring for IPv4,

•IPv6 and MPLS services

Combine both Carrier Ethernet and powerful Packet over SONET/SDH:

•MEF 9 and MEF 14 certified for offering Carrier Ethernet services

•Flexible set of POS interfaces with carrier class timing offering internal stratum 3, loop, line, and BITS timing support
