According to the present invention, a method and system for communicating via a switched virtual circuit (SVC) is provided wherein transmission traffic is monitored between two ATM switches.

One of the key issues for using SVC-based Data Link subnetworks in the TCP/IP environment is the issue of switched virtual circuit (SVC) management.

BGP includes a mechanism for operation over switched virtual circuit (SVC) services which avoids keeping SVCs permanently open and allows it to eliminates periodic sending of KEEPALIVE messages.

A method is disclosed for establishing a switched virtual circuit in a digital network having network nodes with static routing tables.

The method includes establishing a frame relay switched virtual circuit (FR SVC) transport function capability in the source system (202) and, consequently generating a plurality of parameters.

The switched virtual circuit Layer-2 VPN includes logical ports of two types, customer and provider, and port information tables, and uses Layer-3 mechanisms to distribute customer routes.

Then an SVC is launched over the ATM network from the at least one service gateway to connect the subscriber to the ATM network address.

The ATM network must provide multicast and broadcast support, address mapping (MAC-to-ATM), SVC management, and a usable packet format.
