Cisco IOS Technology
The Cisco1760 Modular Access Router benefits from the power of CiscoIOS Software. Forexample, through Cisco
IOS Software, the Cisco 1760 router delivers QoS capabilities, including RSVP, WFQ, CAR, and DSCP Precedence.
These features enable businesses to prioritize traffic on their networks by user, application, traffic type, and other
parameters to ensure that business-critical data and delay-sensitive voice are appropriately prioritized.
Further, for businesses that are increasingly accessing the Internet via DSL, QoS features are necessary to ensure
highest voice quality. For DSL services with QoS features, the Cisco 1760 router can be deployed with the ADSL or
the G.shdsl WAN Interface Card.
The advanced DSL QoS features include the following:
• LFI using MLP over ATM
• Low-latency queuing (also called PQ/CBWFQ)
• Weighted Random Early Detection (WRED)
• Committed Access Rate (CAR)
• Differentiated services (DiffServ) (class-based marking)
