 control element maintains a network topology. The network topology and the traffic intensity data are used by the network control element to compute network traffic routing sets which are identified to the nodes along with an order of preference. The computed routing sets are distributed to the network nodes and used by the network nodes in processing traffic admission requests.
The network nodes include node control elements which control traffic admission, traffic routing and the computation of service-rate allocations for classes of traffic served by egress links at the node.
Edge network node control elements receive traffic admission requests from traffic sources. The edge node control elements compute an equivalent bit rate for each traffic admission request based on a novel method in accordance with the invention. In order to minimize further processing when it is necessary to establish a connection across the network, the edge node control element also computes variables which enable subsequent nodes involved in the connection to rapidly compute an approximate equivalent bit rate used in route selection.
The multi-class digital network in accordance with the invention preferably supports a plurality of digital services which may require different transport modes, each transport mode consisting of at least one transport protocol. Since different transport protocols require different packet sizes, a link controller is provided which accommodates variable packet sizes so that packets need not be disassembled and converted to a standard format by edge device interfaces.
The multi-class digital network adopts a service-rate discipline comprising a guaranteed minimum rate per class in order to ensure efficient use of the network while meeting transmission rate and quality of service commitments. In order to minimize computing requirements for routing, high-frequency, low bit-rate traffic is preferably served by paths commonly referred to as direct routes set up through the network. High bit-rate connection-oriented traffic is preferably served by connections set up on demand. Each service type is preferably assigned to at least one class and each class is preferably assigned to a separate band in the network. The bands are dynamically configured and have elastic boundaries which fluctuate with traffic load. Unused time slots accept traffic from any waiting source in a predetermined hierarchical order in which connectionless traffic without a quality of service is served last. The PDZ domain is a common structural domain of 80-90 amino-acids found in the signaling proteins of bacteria, yeast, plants, and animals. PDZ is an acronym combining the first letters of three proteins—post synaptic density protein (PSD95), Drosophila disc large tumor suppressor (DlgA), and zonula occludens-1 protein (zo-1)—which were first discovered to

The net regional anatomy and the traffic intensity data are use by the network control component to compute network dealings routing set which are identified to the node along with an order of preference. The computed routing set are distributed to the network nodes and used by the network nodes in process traffic admission requests. 
 The net nodes include node control condition elements which operate traffic admission, traffic routing and the computation of service - pace allocations for classes of traffic served by egress links at the node. 
 Edge net lymph node command elements receive traffic admission requests from traffic sources. The edge lymph node control condition elements calculate an equivalent piece pace for each traffic admission request based on a novel method in accordance with the invention. In order to minimize further processing when it is necessary to install a connection across the network, the edge node control element also computes variable which enable subsequent nodes involved in the connection to rapidly calculate an approximate equivalent bit pace used in route selection. 
 The multi - class digital network in accordance with the invention preferably supports a battalion of digital services which may require different transport modes, each transport mode consisting of at least one transport protocol. Since unlike transport protocols require different packet sizes, a connection controller is supply which accommodates varying packet sizes so that packets need not be disassemble and converted to a standard format by edge device interfaces.
