    摘要: Methods for establishing connections via serving edge nodes (11,12) of serving networks (1) and comprising steps of receiving diversity parameters defining diversities between said connections and further connections are provided with steps of exchanging information (basic idea) between different serving edge nodes (11,12) and of, in response to exchanged information, setting up said connections, to allow diverse connections to be established via different edge nodes (11,12), to further reduce risks and consequences from failures (insight). Serving edge nodes (11,12) are coupled via client edge nodes (21,22) in client networks (2) to client source nodes (20). Said exchanged information comprises requests indicating that said connections must be diverse from said further connections. Connection parameters may define any possible part of a connection in such a way that a certain diversity between two connections can be created by making certain connection parameters of both connections different from each other. Diversity parameters may define any kind of diversity and any kind of non-diversity.

    摘要: The present invention relates to a method for resolving hardware addresses into network addresses, which method comprising the steps of:
    - establishing a data path through a data communication network between a source node and an end node, which data path being established by exchanging signaling messages between network nodes along said data path, which signaling exchanges relying upon control network addresses for addressing the network nodes,
    - at the source node, sending a request whereby a particular hardware address associated with the data path is to be resolved into a network address.
    A method according to the invention further comprises the steps of:
    - at the source node, encoding into the request a common path identifier whereby the data path can be identified, and sending the request with as destination network address a particular control network address of a particular network node along the data path, which request being further forwarded towards the end node,
    - at the end node, identifying the data path from the common path identifier, determining whether the data path terminates at the end node, and returning to the source node a particular data network address associated with the data path.
    The present invention also relates to a network node implementing such a method.

    摘要: Network-nodes (10) comprising data exchangers (30) for exchanging data information via a path with other network-nodes (12) forming part of the path and for exchanging data information via a detour path in response to detections of failures in the path, are provided with bandwidth exchangers (31) for, in response to detections/notifications of failures in the path, exchanging bandwidth information with further network-nodes (13) forming part of the detour path. This is a combination of an advantageous aspect of a protection scheme (detour path set-up prior to failure detection) and an advantageous aspect of a restoration scheme (bandwidth allocation after failure detection). A network comprising this network-node (10) is relatively efficient in terms of bandwidth allocation at a relatively short recovery time. The data exchanger (30) exchanges the data information in accordance with a packet/frame/cell-switching procedure. Network-units (20-28) may be located between the network-nodes (10-15) and comprise data exchangers (40) for exchanging the data information in accordance with a circuit-switching procedure.
