1. A method executed in a contention-based network for establishing a two-way communication path from a first node to a second node comprising the steps of:
said first node sending a reservation message destined to said second node, which message requests a reservation of said two-way communication path; said second node receiving said reservation message through a forward path that comprises said first node, said second node, and one or more other nodes of said network, and responding with a reservation confirmation message that is destined to said first node, nodes of said forward path being path nodes; said first node receiving said reservation confirmation message through a reverse path that comprises said first node, said second node, and one or more other nodes of said network, nodes of said reverse path being path nodes; each of one or more first neighbor nodes, which are not one of the path nodes, receiving said reservation message from at least one of the nodes in the forward path and setting itself to a non-transmitting mode of operation for a duration of the reservation of the two-way communication path responsive to receiving said reservation message and not being one of the path nodes; each one or more second neighbor nodes, which are not one of the path nodes, receiving the confirmation message from at least one of said nodes in the reverse path and setting itself to the non-transmitting mode of operation for the duration of the reservation of the two-way communication path responsive to receiving said confirmation message and not being one of the path nodes, wherein the duration of the reservation is determined according to messages flowing through the path nodes without a hiatus of more than a preselected time interval; and wherein the reservation message includes a negotiable field, specifying whether said first node is amenable to proposed changes in the reservation message. |
