Internetworking Terms: SDLC Transport
Cisco router feature with which disparate environments can be integrated into a single, high-speed, enterprise-wide network. Native synchronous data link control (SDLC) traffic can be passed through point-to-point serial links with other protocol traffic multiplexed over the same links. Cisco routers can also encapsulate SDLC frames inside IP datagrams for transport over arbitrary (non-SDLC) networks. Replaces proxy polling.
