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)
