PM9311/2/3/5 Features
• 320 Gbit/s aggregate bandwidth - up to 32 ports of 10 Gbit/s bandwidth each
• Each port can be configured as 4 x OC-48c or 1 x OC-192c
• Both port configurations support four priorities of best-effort traffic for unicast and multicast data traffic
• TDM support for guaranteed bandwidth and zero delay variation with 10 Mbit/s channel resolution
• LCSTM protocol supports a physical separation of switch core and linecards up to 200 feet (70 m)
• Virtual output queues to eliminate head-of-line blocking on unicast cells
• Internal speedup to provide near-output-queued performance
• Cells are transferred using a credit mechanism to avoid cell losses due to buffer overrun
• In-band management and control via Control Packets
• Out-of-band management and control via a dedicated CPU interface
• Optional redundancy of all shared components for fault tolerance
• Efficient support for multicast with cell replication performed within the switch core
