Method for distributing sets of collision resolution parameters in a frame-based communications network
First Claim
1. A method for distributing sets of collision resolution parameters to be used for resolution of network access contention events among nodes of a non-centralized media access control shared medium network, comprising:
- providing a set of collision resolution parameters which includes a sequence of fixed numbers for resolving a single network access contention event;
identifying a single collision signal slot master node when one or more candidate collision signal slot master nodes exist;
sending collision signal slot request messages from client nodes addressed to all network nodes, wherein a collision signal slot request message includes;
a unique client identifier to indicate source of request;
an indication that a collision resolution parameter set is required by a uniquely identified requesting client node; and
an indication of number of active packet-generating channels at the uniquely identified requesting client node;
sending collision signal slot assignment messages from the master node to the client nodes, wherein a collision signal slot assignment message includes;
a list of unique client identifiers to indicate those client nodes which can find collision resolution parameter set information within the collision signal slot assignment message;
a list of collision resolution parameter set information unambiguously associated on a one-for-one matching basis with the list of unique client identifiers;
obtaining at a given client node from within a received collision signal slot assignment message a collision resolution parameter set to be employed by that given client node;
sending collision signal slot acknowledgment messages from client nodes addressed to all network nodes, wherein a collision signal slot acknowledgment message includes;
a unique client identifier to indicate source of the collision signal slot acknowledgment message; and
collision resolution parameter set information currently assigned to the uniquely identified client node; and
sending collision signal slot drop messages from client nodes addressed to all network nodes, wherein a collision signal slot drop message includes;
a unique client identifier to indicate source of the collision signal slot drop message; and
an indication that a collision resolution parameter set is no longer required by the uniquely identified client node.

Abstract
A method for distributing sets of collision resolution parameters to be used for resolution of network access contention events among nodes of a non-centralized media access control shared medium network. A set of collision resolution parameters is provided which includes a sequence of fixed numbers for resolving a single network access contention event. A single collision signal slot master node is identified when one or more candidate collision signal slot master nodes exist. Collision signal slot request messages are sent from client nodes addressed to all network nodes. Collision signal slot assignment messages are sent from the master node to the client nodes. A collision resolution parameter set to be employed by that given client node is obtained at a given client node from within a received collision signal slot assignment message. Collision signal slot acknowledgment messages are sent from client nodes addressed to all network nodes. Collision signal slot drop messages are sent from client nodes addressed to all network nodes.
