摘要： Networks (8) for setting up connections between nodes (1,2) via request messages (R1) and allocation messages (A1) are made more efficient by providing the request messages (R1) with indications for indicating the first node's capabilities with respect to different signalling procedures and by providing the allocation messages (A1) with instructions for instructing the first nodes (1) to use one of the signalling procedures. Only one round trip is needed. The indications comprise first preference values for the first signalling procedure (wavelength switching) and second preference values for the second signalling procedure (waveband switching). The instructions comprise signalling information and signalling procedure assignments. The second nodes (2) run label assignment algorithms for making the signalling procedure assignment in dependence of the preference values. The first nodes (1) derive further signalling information from the signalling information, which signalling information is related to the first signalling procedure and which further signalling information is related to the second signalling procedure.

摘要： The present invention provides a technique for conveying Inverse Address Resolution Protocol (InARP) packets between a source node and an end node. A data path is established through a data communication network between the source node and the end node by exchanging signaling messages between network nodes along the data path. InARP requests are sent through the control address space used for controlling the operation of the network. At the source node, a common path identifier that identifies the data path is encoded into a request that is sent to the end node for identifying a particular data path that terminates at that end node, and for returning a data network address associated with that data path.

摘要： Communication network routing apparatus and techniques using logical communication links are disclosed. A routing apparatus identifies a logical communication link that it is capable of being used to establish a virtual connection with another routing apparatus within a virtual connection operational domain, which includes multiple sub-domains, of an underlying communication system. A destination that is associated with the routing apparatus and is reachable through the virtual connection is also identified. Information that is indicative of the identified logical communication link and of the identified destination is provided for distribution from a sub-domain of the routing apparatus in the virtual connection operational domain to another sub-domain within the virtual connection operational domain. This distribution of information enables a routing apparatus in one sub-domain to dynamically route a virtual connection toward a destination in a different sub-domain. Data structures for distributing the information are also disclosed.
