摘要： A method is provided for use at a first node of a network. The first node (B) has an input path for receiving Ethernet frames destined for a second node of the network. The first node (B) also has a first output (working) path for forwarding the received Ethernet frames towards the second node. A failure along the first output (working) path is detected at the first node. Following such failure detection, the received Ethernet frames are caused, at the first node, to be re-routed along a second output (backup) path, different to the first output (working) path, towards the second node. The re-routing is performed by using (e.g. referring to and/or changing) respective indications (VLAN1) applied to the Ethernet frames to distinguish those Ethernet frames to be forwarded along the first output (working) path from those Ethernet frames to be forwarded along the second output (backup) path.

摘要： In a packet switched telecommunications networks a dimensioning method, a dimensioning tool and network links dimensioned according to the method and with the help of the tool are provided. The idea behind the embodiments of the invention that, a so called operation point, representing the most representative traffic mix on a link shall be defined to calculate the effective bandwidth of a connection. In accordance with the implementation, the dimensioning method uses an inverted Call Admission Control (CAC) method and Offered Load to calculate effective bandwidths. The effective bandwidths are then used in the Kaufman-Roberts formula for network dimensioning. The inverted CAC method calculates the minimum capacity required to admit a given number of connections from different traffic classes. The operation point of the system is calculated based on the Offered Load and Grade of Service (GoS) requirement. The effective bandwidths are then calculated using the operation point.

摘要： A call admission control system and method for Internet Protocol (IP) Differentiated Services (DiffServ) network having at least one node for interpreting signaling messages and controlling traffic load in the network. The method consists of an initialization (601) and a real-time phase (602). In initialization phase (601), coefficients of the approximating hyperplanes are computed (61) and stored (62). This phase is repeated when the descriptor of a traffic class changes (63), which usually happens when nodes are configured or reconfigured. A traffic mix is admissible (67), if for each real-time traffic class both the stability (65) and the delay (66) constraints are fulfilled. Stability is tested by evaluating the number of lost packets and comparing it to the tolerated packet loss ratio for each class in that queue. Delay constraint is tested by checking if the traffic mix is below at least one of the approximating hyperplanes in the space of number of sessions for each class.

摘要： There is disclosed a manner of managing the active topology, that is the scheme for forwarding data, in a computer network such as an Ethernet local area network. A root bridge is selected from a plurality of bridges in the network; the root bridge calculating at least one spanning tree from a topology database that has been populated by bridge neighbor information gleaned from link state advertising messages. The root bridge may also calculate an alternate topology for implementation in the event a failure condition that affects the primary spanning tree is detected. The root bridge then advertises the spanning tree and remotely configures the port states of the bridges in the spanning tree through tree advertising messages that the bridges are arranged to process and set their ports accordingly.
