摘要 |
A network arrangement for transporting service (Servco) traffic between terminals via an asynchronous path comprises a servco access layer incorporating multimedia gateways for access by said terminals, an asynchronous network layer, a service layer incorporating adaptation layer switches each coupled to the network layer, and a transport layer providing a connection medium between the adaptation layer switches. The Servco traffic is carried in ATM minicells over the network layer. Delineation of the minicells is effected by searching the received ATM stream for a valid code word indicating the start of a minicell, and, for that minicell and subsequent minicells, determining length information so as to determine the start of each next minicell. |
