2600 Series provides a ﬂexible, integrated solution that simpliﬁes

the process of deploying and managing the branch ofﬁce network

solutions.

Rather than adding bandwidth or raising CIRs to support

new network services such as voice, bandwidth management

techniques can control or reduce costs and improve network

performance. The Cisco IOS offers a variety of traffic shaping,

prioritization, filtering, congestion management features such as

Committed Access Rate (CAR), Custom, Priority and Weighted

Fair Queuing (WFQ), Resource Reservation Protocol (RSVP),

Weighted Random Early Detection (WRED), and Policy Based

Routing. These capabilities will also decrease latency and

improve application availability, critical for supporting legacy

SNA protocols and voice/video connections. The

Data Compression AIM off-loads the Cisco 2600’s CPU,

maximizing performance levels for other bandwidth

management, routing and switching duties.
