Abstract
The invention relates to a method for transmitting one or more client signals via a packet transport network. According to the method, packets of the one or more client signals are received at an ingress node of the network. Timing information characterizing the timing of the received packets is determined and the received packets are mapped into a container. The container and the timing information are transmitted via the network. At an egress node of the network, the packets are extracted from the container and the packets are timed for further transmission based on the transmitted timing information.
Claims13
A method of transmitting packets via a packet transport network, the method comprising the steps of:
- at an ingress node of the network,
- receiving and accumulating packets of one or more client signals;
- determining timing information characterizing the timing of the received packets;
- and
- mapping the accumulated packets into a container;
- transmitting the container and the timing information via the network;
- and
- at an egress node of the network,
- receiving the container;
- and
- extracting the packets from the container and timing the packets for further transmission based on the timing information,
- wherein the earliest received packet to be transmitted in a respective container waits at the ingress node and at the egress node together for an essentially constant time period, the ratio between the portion of the time period at the ingress node and the portion of the time period at the egress node being dependent on the load of the ingress node.
A packet transport network, comprising:
- at an ingress node of the network, a first network element comprising:
- means for receiving and accumulating packets of one or more client signals to be transmitted via the network;
- determining means for determining timing information characterizing the timing of the packets;
- mapping means for mapping the accumulated packets into a container;
- and
- transmitting means for transmitting the container and the timing information via the network;
- and
- at an egress node of the network, a second network element comprising:
- receiving means for receiving the container as generated by the first network element at the ingress node of the network;
- and
- extracting means for extracting the packets from the container and timing means for timing the packets for further transmission based on the timing information,
- wherein the packet transport network is configured such that each earliest received packet to be transmitted in a respective container waits at the ingress node and at the egress node together for an essentially constant time period, the ratio between the portion of the time period at the ingress node and the portion of the time period at the egress node being dependent on the load of the ingress node.
