摘要： The invention provides a coordination layer of coordinating entities provided intermediate the admission control interfaces of the transport network domains, and any QoS signaller which signals QoS requests on behalf of the application layer. The coordination layer acts to distribute an admission control request across the multiple transport network domains by the use of coordination request messages containing the admission control request being forwarded through the coordination layer of coordinating entities. At each coordinating entity the admission control request is passed on to the admission control interface of the transport network which the coordinating entity serves, and an admission control response obtained. This admission control response is then combined with admission control responses from the other domains which are propagated through the coordination layer via coordination messages. The result is that the coordination layer acts to combine the various admission control responses into a combined response, which can be provided back to the QoS signaller (or other requesting entity). Thus, coordination of admission control across multiple transport network domains is achieved, without a QoS signaller having to contact each individual domain.

摘要： The present invention provides a method and system wherein congestion information is taken from a lower level in the protocol stack and used for congestion marking in a higher layer. In particular, the method and system of the invention from a first aspect provide for congestion information in the lower layer to be generated downstream at a congested node, and to be fed back upstream to a source node. The source node then passes the congestion information, or information derived therefrom, up to the corresponding network element responsible for higher layer functions in the protocol stack, where higher level congestion marking can then be performed in dependence on the received lower level congestion information. Thus, congestion information from the lower layer which can typically be generated earlier before significant congestion occurs can be used in higher layer congestion control functions. Preferably the lower layer is the data link layer, and the higher layer is the network layer.

摘要： Downstream path congestion is measured in respect of a node via which a plurality of data units are traversing an end-to-end path from a sender to a receiver. Each data unit has a first indication settable in dependence on information from the receiver to each of at least two states whereby to indicate different levels of congestion experienced on the end-to-end path by data units previously received by the receiver, and a second indication settable to an initial state and to at least one updated state indicative of congestion experienced by data units on their path from the sender to said node. A plurality of data units are received at the node, and the downstream path congestion measure is determined in dependence on an inflation factor itself dependent on the proportion of a set of the data units whose second indication on receipt at the node is in the initial state.
