A method for implementing bandwidth reservation in an electronic network comprises the setup of a new connection between at least two nodes in a network, while preventing the overload of individual nodes, and the overload of the network bus, or a radio network. In one embodiment, the present invention is implemented through the use of a plug traffic list for each node to indicate the total capability to sink and/or receive, the outgoing communications, and the incoming communications. The invention also preferably includes a bus traffic list to indicate the load of the network bus. According to the present invention, a node that wishes to establish a new communication preferably first determines whether all nodes that are planned to participate in the new connection have enough capacity to handle the additional plug traffic, whereafter the capacity of the network bus is checked. If any involved node or the network bus does not possess enough capacity, it is possible for the node that seeks the new connection to pre-empt other connections. The present invention functions on networks that support various transmission speeds between two communication partners.
