The complete form of DCAP is Link Switching Client Access Protocol. It is the data link layer protocol used between workstations and routers to transfer SNA / NetBIOS traffic through TCP sessions.
DLSw data link switching is a means of the System Network Engineering (SNA) tunnel and NetBIOS traffic through an IP network. Before developing DLSw, SNA and NetBIOS traffic was transferred through Source-Route Bridging (SRB), which is a transport protocol in token loop environments.
In a large network, DCAP addresses the problem of scalability by significantly reducing the number of peers that connect to the central site router. Workstations (DCAP clients) and the router (DCAP server) work in client / server relationships. Workstations are connected to a DCAP server. The DCAP server has a peer connection to the central site router.
DLSw uses the switching protocol to switch instead of SRB between routers to create DLSw peer connections, locate resources, redirect data, manage flow control and error recovery. Routers are called data link switches.
The Clien tAccess Protocol data hierarchy provides a hierarchical structure to solve scalability problems. All workstations are clients of the router and not their counterparts of the router. This creates the client / server model. It also provides a more efficient protocol between the workstation and the router.
