Abstract
A method for establishing clock tracing relations and an apparatus for computing clock tracing relations are disclosed. The method includes: computing a Shortest Path Tree (SPT) from a clock source access node to other nodes in a network; selecting nodes governed by the clock source access node according to the SPT and the source information corresponding to the SPT; and establishing clock tracing relations from the clock source access node to the governed node consecutively along the SPT. The apparatus for computing clock tracing relations includes: a path computing unit, a source selecting unit, and a path issuing unit.
Claims13
A method for establishing clock tracing relations, comprising:
- computing a Shortest Path Tree (SPT) from a clock source access node to other nodes in a network;
- selecting nodes governed by the clock source access node according to the SPT and source information corresponding to the SPT;
- and
- establishing clock tracing relations from the clock source access node to the governed nodes consecutively along the SPT.
A method for establishing a clock tracing relation, comprising:
- computing a Shortest Path Tree, SPT, from a clock source access node to other nodes in a network;
- selecting a node governed by the clock source access node according to the SPT and source information corresponding to the SPT;
- and
- delivering the SPT and path information of the node governed by the clock source access node to the clock source access node corresponding to the governed node, wherein the SPT and the path information of the governed node are used for the clock source access node to establish a clock tracing relation.
An apparatus for computing clock tracing relations, deployed on a clock source access node in a network, wherein the apparatus comprises:
- a path computing unit configured to compute a Shortest Path Tree (SPT) from a clock source access node to other nodes;
- a source selecting unit configured to select nodes governed by the clock source access node according to the SPT and clock source information corresponding to the SPT;
- and
- a tracing triggering unit configured to establish clock tracing relations from the clock source access node to the governed nodes consecutively along the SPT.
