The G.shdsl WAN Interface Cards for the Cisco 2600 and 3700 provide support for ATM Class of Service (CoS)

(CBR, VBR-nrt, VBR-rt, and UBR) features that enable service providers to manage their core ATM network

infrastructures to deliver scalable, cost-effective services with CoS guarantees to their customers.

Permanent-virtual-circuit (PVC) trafﬁc shaping and queuing allow further optimization of the existing bandwidth

between customers and various services.

Congestion Avoidance

• Class-Based Weighted Random Early Detection (WRED) with DSCP (Egress)

Policing and Trafﬁc Shaping

• Class-Based Policing

• Per-ATM VC shaping for VBR—nrt

• ATM Cell Loss Priority (CLP) Bit Marking

Link Efﬁciency

• Selectable Transmit Ring Setting of 3 or 24 packets

• Tunable Tx Ring Buffer for values 2 through 60

• Multilink Point-to-Point Protocol (MLPPP) fragmentation with interleaving (LFI)

• Multilink Point-to-Point Protocol (MLPPP) with LLQ, CBWFQ, and other QoS features

• Compressed Real-Time Transport Protocol (cRTP)

Other (IP QoS)

• Local Policy Routing (LPR)

• Policy-Based Routing (PBR)

• IP QoS map to ATM Class of Service
