Service providers face the challenge of meeting customer demand by building scalable, feature-rich networks that can deliver value-added services such as private IP connectivity; integrated data, voice, and video services; and tiered service offerings-at all interface rates without compromising density or line-rate performance. The Cisco IP Services Engine (ISE) line cards provide the same powerful feature set as the standard POS line cards and also accommodate service provider requirements by providing an extensive set of service-enabling edge features at line rate such as packet classification, congestion avoidance, and low-latency queuing (LLQ).
