Abstract:
A packet transport network for efficiently transferring customer digital data between two of a plurality of transport access interfaces in a series of transport packets comprising:a plurality of routing nodes, each having a routing table, for routing the transport packets through routing links; wherein each of the transport access interfaces has an address table correlating destination of the customer digital data composed of a plurality of digital data flows with an address of a destination transport access interface for connecting one or more customer terminals through a customer access line on one side and to a routing node through a routing link on the other; and wherein each of the transport access interfaces has an encapsulating module for encapsulating/decapsulating between the plurality of digital data flows identified above on the customer access line and the series of transport packets having a transmission control protocol (TCP) header on the routing links, the encapsulating module including a TCP processor for at least administering an admission process regulating the transport packets, a TCP header module for assigning the TCP header to more than one of the plurality of digital data flows, and a transport internet protocol (TIP) header module for assigning a TIP header to each TCP header and corresponding more than one of the plurality of digital data flows.
