Abstract
A node generates a delay measurement frame and transmits it to an adjacent node of an Ethernet ring network in order to measure a delay of the network. The node receives the delay measurement frame generated by the node from another adjacent node of the ring network, and measures a network delay by using the received delay measurement frame.
Claims19
A method for measuring a delay of an Ethernet ring network at a node of the Ethernet ring network, the method comprising:
- generating a delay measurement frame;
- transmitting the delay measurement frame to an adjacent node of the ring network;
- receiving the delay measurement frame generated by the node from another adjacent node of the ring network;
- and
- measuring a network delay by using the received delay measurement frame.
An apparatus for measuring a delay of an Ethernet ring network at a node of the network, the apparatus comprising:
- a delay measurement frame generator for generating a delay measurement frame;
- a transmitter for transmitting the delay measurement frame to an adjacent node of the ring network;
- a receiver for receiving the delay measurement frame generated by the node from another adjacent node of the ring network;
- and
- a measurer for measuring a network delay by using the received delay measurement frame.
