Web Cache Communication Protocol (WCCP) is a content-routing protocol that provides a mechanism to redirect traffic flows in real-time. It has built-in load balancing, scaling, fault tolerance, and service-assurance (failsafe) mechanisms.
The Web Cache Communication Protocol (WCCP) is a Cisco-developed protocol that allows certain Cisco routers and switches to transparently redirect traffic to a cache engine such as a ProxySG appliance. This traffic redirection helps to improve response time and optimize network resource usage.
The ProxySG can be configured to participate in a WCCP scheme, in which WCCP-capable switches or routers collaborate with ProxySG appliances to form one or more groups that service requests from clients.
