Switching performance isindependent of the number of route entries or advanced Layer 3services enabled. Hardware-based Cisco Express Forwardingrouting architecture allows for increased scalability andperformance. Cisco Express Forwarding architecture allows for veryhigh-speed lookups while also ensuring the stability and scalabilitynecessary to meet the needs of future requirements.The Cisco Catalyst 4000 with Supervisor Engine IV is a platformoptimized for multimedia applications with its advanced multicastsupport. Supervisor Engine IV supports Internet GroupManagement Protocol (IGMP) snooping in hardware, enhancingthe performance of multimedia applications and reducing networktraffic by allowing a switch to dynamically add and remove hostsfrom a multicast group.
