Abstract
A node of a network includes a network interface configured to receive outgoing bidirectional forward detection (BFD) echo packets transmitted from an originating node and to transmit return BFD echo packets with queue depth information appended thereto back to the originating node; a queue depth information generator configured to collect queue depth information; and a processor configured to append the queue depth information to the outgoing BFD echo packets. Other apparatus and methods are disclosed.
Claims21
A node of a network, the node comprising:
- a network interface configured to receive outgoing bidirectional forward detection (BFD) echo packets transmitted from an originating node and to transmit return BFD echo packets with queue depth information appended thereto back to the originating node;
- a queue depth information generator configured to collect queue depth information;
- and
- a processor configured to append the queue depth information to the outgoing BFD echo packets.
A node of a network, the node comprising:
- a network interface configured to receive return bidirectional forward detection (BFD) echo packets with first queue depth information appended thereto from at least a first node of the network;
- and
- a processor coupled to the network interface, wherein the processor is configured to extract the first queue depth information from the return BFD echo packets.
A method of operating a network, the method comprising:
- providing a network having at least a first node and a second node;
- acquiring first queue depth information in the second node;
- transmitting outgoing BFD echo packets from the first node to the second node;
- receiving the outgoing BFD echo packets in the second node;
- appending the first queue depth information to at least one return BFD echo packet;
- and
- transmitting the at least one return BFD echo packet with the first queue depth information appended thereto to the first node.
The method of claim further comprising:
- acquiring third queue depth information at a fourth node;
- transmitting outgoing BFD echo packets from the first node to the fourth node;
- receiving the outgoing BFD echo packets in the fourth node;
- appending the third queue depth information to at least one return BFD echo packet;
- and
- transmitting the at least one return BFD echo packet with the third queue depth information appended thereto to the first node.
A network for transmitting data, the network comprising:
- a first node;
- and
- a second node,
- wherein:
- the first node is configured to:
- transmit outgoing BFD echo packets to the second node;
- receive return BFD echo packets from the second node;
- and extract first queue depth information from the return BFD echo packets, and
- the second node is configured to:
- receive the outgoing BFD echo packets from the first node;
- append the first queue depth information to the return BFD echo packets;
- transmit the return BFD echo packets back to the first node.
