网络模块性能 Cisco 7600 Route Switch Processor 72Gbps fabric, PFC3CXL, GE

The Cisco 7600 RSP 720 uses the same high-performance 720-Gbps crossbar switch fabric as that used by the Cisco Catalyst® 6500 Series Supervisor Engine 720 and combines it with a new, revised, and application-specific integrated circuit (ASIC)-based forwarding engine. This single module delivers 40 Gbps of switching fabric capacity per slot, supporting 4-port 10 Gigabit Ethernet and 48-port 10/100/1000 density line cards. With hardware-enabled forwarding for IPv4, IPv6 Unicast and Multicast, and Multiprotocol Label Switching (MPLS), the Cisco RSP 720 can provide high-speed central forwarding with rich packet processing features such as access control lists (ACLs), quality of service (QoS), MPLS VPNs, and more. Combining the Cisco 7600 RSP 720 with distributed forwarding cards (DFCs), the total system performance can scale up to 400 Mpps.

The Cisco 7600 RSP 720 delivers a rich set of IP features in hardware for applications such as subscriber aggregation, IP forwarding, Layer 2 and Layer 3 MPLS VPNs, and Ethernet over MPLS (EoMPLS) with quality of service (QoS) and security features.

The Cisco 7600 RSP 720 comes integrated with two new daughter cards:

• Policy Feature Card (PFC-3C or PFC-3CXL) - Performs Layer 2 and Layer 3 forwarding in hardware with constant performance, even with intensive features enabled such as ACLs, QoS, generic routing encapsulation (GRE), or Network Address Translation (NAT); the Policy Feature Card performs the following functions:

– Performs Layer 2 and Layer 3 forwarding

– Enforces ACL functions

– Performs QoS policing and marking

– Collects NetFlow statistics

– Offers Control Plane Policing (CoPP)

• Multilayer Switch Feature Card (MSFC4) - Runs Layer 2 and Layer 3 protocols and performs all the control-plane functions
