Abstract:
A method to reserve bandwidth for a connection of at least two nodes connected to each other via a bus (5) in a network including a resource manager (4), comprising the steps of:issuing a request from a requesting node (2), which is preparing a new connection, for whether each network node (2, 3; 1, 2, 3) that is planned to participate in the new connection has sufficient resources to participate in said new connection; andrequesting needed network bandwidth through the resource manager (4), wherein an answer to the request, as to whether said each network node (2, 3; 1, 2, 3) that is planned to participate in the new connection has sufficient resources to participate in said new connection, is decided based on a plug traffic list of a maximal bandwidth that a respective node (2, 3; 1, 2, 3) can handle, and a bandwidth of said respective node (2, 3; 1, 2, 3) already reserved for other purposes, and wherein said plug traffic list of the respective node (2, 3; 1, 2, 3) is stored within said respective node (2, 3; 1, 2, 3), said request, for whether said each network node (2, 3; 1, 2, 3) that is planned to participate in the new connection has sufficient resources to participate in said new connection, is performed by requesting said each network node (2, 3; 1, 2, 3) that is planned to participate in the new connection as to whether said each network node has sufficient resources to participate in said new connection, and a requested node (2, 3; 1, 2, 3) makes an entry concerning the planned new connection into its plug traffic list, and transmits a positive resource message to the requesting node (2) in the event that the requested node has sufficient resources to participate said new connection, otherwise the requested node transmits a negative resource message to the requesting node (2).
