1-8 Packet Over SONET Module Installation and User Guide
Overview
• Efficient support for IP routing over SONET via IPCP
• Support for Transparent LAN Services (TLS) over SONET via BCP
• Support for MultiProtocol Label Switching Control Protocol (MPLSCP) via PPP
• Support for jumbo frames
• Extensive support for Quality of Service (QoS) and Differentiated Services (DiffServ),
including:
— Eight ingress queues and eight egress queues per interface
— Ingress and egress rate shaping and limiting
— IEEE 802.1Q VLAN priorities
— Weighted RED (WRED) congestion avoidance algorithm
— Assured Forwarding and Expedited Forwarding RFCs
• Support for service provider specific features, such as:
— Flexible remapping of DiffServ codepoints
— Flexible remapping of IEEE 802.1Q VLAN IDs
— VLAN tunneling via nested 802.1Q tags
— Port tunneling of High-Level Data Link Control (HDLC) byte streams
• Support for NetFlow Version 1 per-flow statistics, including:
— Capacity for two million flow records per PoS module
— Scalability via distribution to groups of flow-record collector devices
— Filters enabling statistics to be maintained for selected flows
— Aggregation option for further reducing the volume of exported data
• Resiliency with fast recovery from SONET link failures via support for Automatic
Protection Switching (APS) protocol in multiple configurations, including networks
where the working and protection lines are:
— Terminated in the same SONET module
— Terminated in different SONET modules residing in the same BlackDiamond 6800
series system
— Terminated in different SONET modules residing in different BlackDiamond 6800
series systems
