Abstract
An apparatus may include a physical layer (PHY), a reconciliation sublayer (RS), a Media Access Control layer (MAC), and a logic circuit acting as a Central Segment Controller or Local Node Manager. The PHY may interface with a shared transmission medium of a network. The RS may support Physical Layer Collision Avoidance (PLCA), and the circuit may send a request to register a node with a network, and derive a node identifier for use by the PLCA RS to determine transmit opportunities, wherein the node identifier is at least partially derived from the node's position in a table of registered nodes in the network received in response to the registration request.
Claims23
An apparatus, comprising:
- a physical layer (PHY) to interface with a shared transmission medium of a network;
- a reconciliation sublayer (RS) that supports Physical Layer Collision Avoidance (PLCA);
- a Media Access Control layer (MAC);
- and
- a Local Node Management logic circuit to:
- send a request to register a node with a Central Segment Controller;
- and
- derive a node identifier for use by the PLCA RS to determine transmit opportunities, wherein the node identifier is at least partially derived from the node's position in a table of registered nodes in the network received in response to the registration request.
A method comprising:
- sending a request to register a node with a Central Segment Controller;
- and
- deriving a node identifier for use by a reconciliation sublayer (RS) that supports Physical Layer Collision Avoidance (PLCA) to determine transmit opportunities, wherein the node identifier is at least partially derived from the node's position in a table of registered nodes in the network, the table of registered nodes received from the Central Segment Controller in response to the registration request.
