Abstract
A method of operation of a Multiprotocol Label Switching network involves, in an active node of the network, receiving a first data packet from a source node and forwarding the first data packet to a destination node. At the same time, the active node measures a residence time of the first data packet in the active node. The active node then sends a further data packet containing residence time information.
Claims22
A method of operation of a Multiprotocol Label Switching network, the method comprising, in an active node of the network:
- receiving a first data packet from a source node;
- forwarding the first data packet to a destination node, the first data packet comprising a flag indicating if a two-step mode is being used;
- and
- when the flag indicates that the two-step mode is being used:
- measuring a residence time of the first data packet in the active node;
- and
- sending a further data packet containing residence time information of the first data packet.
A Multiprotocol Label Switching, MPLS, network node, being configured for:
- receiving a first data packet from a source node;
- forwarding the first data packet to a destination node, the first data packet comprising a flag indicating if a two-step mode is being used;
- and
- when the flag indicates that the two-step mode is being used:
- measuring a residence time of the first data packet in the active node;
- and
- sending a further data packet containing residence time information of the first data packet.
A Multiprotocol Label Switching, MPLS, network node, comprising:
- a processor;
- and
- a memory, said memory containing instructions executable by said processor to configure the node to:
- receive a first data packet from a source node;
- forward the first data packet to a destination node, the first data packet comprises a flag indicating if a two-step mode is being used;
- and
- when the flag indicates that the two-step mode is being used:
- measure a residence time of the first data packet in the active node;
- and
- send a further data packet containing residence time information of the first data packet.
