Claim Text:
1. A method executed in a contention-based network for establishing a two-way communication path including a forward path and a reverse path between a first node and a second node, the method comprising: said first node sending a reservation message addressed to said second node through said forward path, which reservation message requests a reservation of said two-way communication path, said forward path including said first node, said second node, and one or more other nodes of said network; said second node, in response to said reservation message, sending a reservation confirmation message to said first node through said reverse path, said reverse path including said second node, said first node, and one or more other nodes of said network; each of one or more first neighbor nodes, which are not path nodes, that receives said reservation message from at least one of the nodes in the forward path, 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, said path nodes being nodes in the forward path and nodes in the reverse path; each one or more second neighbor nodes, which are not path nodes, that receives the confirmation message from at least one of said nodes in the reverse path, 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 reservation message includes a negotiable field, specifying whether said first node is amenable to proposed changes in the reservation message.
