Overview

port, and DiffServ

Bandwidth shaping

Port-based rate limiting

provides per-port ingress-/egress-enforced increased bandwidth

Classifier-based rate limiting

uses an access control list (ACL) to enforce increased bandwidth for ingress traffic on each port

Reduced bandwidth

provides per-port, per-queue egress-based reduced bandwidth

Traffic policing

supports Committed Access Rate (CAR) and line rate

Congestion avoidance

Weighted Random Early Detection (WRED)/Random Early Detection (RED)

Powerful QoS feature

supports the following congestion actions: strict priority (SP) queuing, weighted round robin (WRR), weighted fair queuing

(WFQ), and WRED

Resiliency and high availability

Redundant/Load-sharing fabrics, management, fan assemblies, and power supplies

increase total performance and power available while providing hitless, stateful failover

Hot-swappable modules

allow replacement of modules without any impact on other modules

Separate data and control paths

keep control separated from services and keep service processing isolated; increase security and performance

Passive design system

backplane has no active components for increased system reliability

Intelligent Resilient Framework (IRF)

creates virtual resilient switching fabrics, where two or more switches perform as a single L2 switch and L3 router; switches do

not have to be co-located and can be part of a disaster-recovery system; servers or switches can be attached using standard

LACP for automatic load balancing and high availability; can eliminate the need for complex protocols like Spanning Tree

Protocol, Equal-Cost Multipath (ECMP), or VRRP, thereby simplifying network operation

IRF capability

provides single IP address management for a resilient virtual switching fabric of up to four switches

Rapid Ring Protection Protocol (RRPP)

provides standard sub 200 ms recovery for ring-based Ethernet topology (Comware v5 only)

Virtual Router Redundancy Protocol (VRRP)

allows groups of two routers to dynamically back each other up to create highly available routed environments

Device Link Detection Protocol (DLDP)

monitors link connectivity and shuts down ports at both ends if unidirectional traffic is detected, preventing loops in STP-based

networks

Hitless patch upgrades

allow patches and new service features to be installed without restarting the equipment, increasing network uptime and

facilitating maintenance

IEEE 802.3ad Link Aggregation Control Protocol (LACP)

supports up to 1024 trunk groups and up to 16 members per trunk; supports static or dynamic groups and a user-selectable

hashing algorithm

Graceful restart

supports graceful restart for OSPF, IS-IS, BGP, LDP, and RSVP; the network remains stable during the active-standby switchover;

after the switchover, the device quickly learns the network routes by communicating with adjacent routers; forwarding remains

uninterrupted during the switchover to achieve nonstop forwarding (NSF)
