Abstract
A user network interface (UNI) path setting method includes advertising an attribute and state information of a TNA interface, and updating a database using information collected through the advertising, computing a path to a destination TNA address from a source TNA address satisfying UNI path setting parameter information included in a path message in consideration of an attribute and state information of the updated TNA interface/link when receiving a path setting request message from an operator, transmitting a path message to a destination through a network based on the computed path, and transmitting a reservation (RESV) message for UNI path generation to a source through the network when normally receiving, by the destination, the path message.
Claims8
A user network interface (UNI) path setting method by UNIs in a network in which a predetermined transport network assigned (TNA) address is used between a client and a UNI-network (UNI-N), comprising:
- advertising, by the UNI-Ns, an attribute and state information of a TNA interface, and updating a database using information collected through the advertising;
- computing, by the UNI-N, a path from a source TNA address to a destination TNA address, in consideration of an attribute and state information of the updated TNA interface/link when receiving a path setting request message wherein the path satisfies UNI path setting parameter information included in a path message;
- and
- setting a UNI path in accordance with the computed path.
A UNI path setting apparatus in a network in which a predetermined TNA address is used between a client and a UNI-N, comprising:
- a routing unit configured to advertise an attribute and state information of a TNA interface and update a database using information collected through the advertisement;
- a path computation unit configured to compute a path from a source TNA address to a destination TNA address, satisfying UNI path setting parameter information included in a path message in consideration of an attribute and state information of the updated TNA interface/link when receiving a path setting request message from an operator;
- and
- a signaling unit configured to transmit the computed path information to the network.
