Abstract
A network device distributes a plurality of symbol blocks, received via a plurality of input streams, to a plurality of output links comprised in a defined connection according to a mapping of the symbol blocks to the output links. Responsive to an input stream of the plurality of input streams being empty such that an expected symbol block is not received, the network device distributes idle data to the output link mapped to the expected symbol block to maintain the mapping of the symbol blocks to the output links. The network device transmits the symbol blocks and idle data over the defined connection via the plurality of output links and according to the distribution.
Claims18
A network entity comprising:
- processing circuitry configured to group traffic in a communication network onto a defined connection comprising a plurality of output links, the traffic comprising a plurality of input streams, each input stream carrying symbol blocks;
- wherein to group the traffic onto the defined connection, the processing circuitry comprises scheduling circuitry configured to associate each symbol block to be transmitted during a predetermined time interval with a corresponding output link according to a one-to-one correspondence;
- and
- wherein to associate each symbol block to be transmitted during the predetermined time interval, the scheduling circuitry is configured to adapt to varying characteristics of at least one among the output links and input streams.
A network entity comprising:
- processing circuitry configured to ungroup traffic in a communication network from a defined connection comprising a plurality of input links onto a plurality of output streams, each input link carrying symbol blocks;
- wherein to ungroup the traffic, the processing circuitry comprises scheduling circuitry configured to associate each symbol block received during a predetermined time interval with a corresponding output stream according to a one-to-one correspondence;
- and
- wherein to associate each symbol block received during the predetermined time interval, the scheduling circuitry is configured to adapt to varying characteristics of at least one among the output streams and input links.
A system configured to exchange traffic in a communication network over a defined connection comprising a plurality of links, the system comprising:
- a first network entity comprising first processing circuitry configured to group traffic onto the defined connection, the traffic comprising a plurality of input streams, each of the input streams carrying symbol blocks, wherein to group the traffic the first processing circuitry comprises first scheduling circuitry configured to associate each symbol block to be transmitted during a first predetermined time interval with a corresponding link according to a first one-to-one correspondence;
- a second network entity comprising second processing circuitry configured to ungroup traffic in the communication network from the defined connection comprising the plurality of links onto a plurality of output streams, each of the links carrying one or more of the symbol blocks, wherein to ungroup the traffic the second processing circuitry comprises second scheduling circuitry configured to associate each symbol block received during a second predetermined time interval with a corresponding output stream according to a second one-to-one correspondence;
- wherein to associate each symbol block received during the second predetermined time interval, the second scheduling circuitry is configured to adapt to varying characteristics of at least one among the output streams and the links.
A method, implemented by a network entity, the method comprising:
- grouping traffic in a communication network onto a defined connection comprising a plurality of output links, the traffic comprising a plurality of input streams, each input stream carrying symbol blocks,
- wherein grouping the traffic comprises associating each symbol block to be transmitted during a predetermined time interval with a corresponding output link according to a one-to-one correspondence;
- and
- wherein associating each of the symbol blocks to be transmitted during the predetermined time interval comprises adapting to varying characteristics of at least one among the output links and input streams.
A method, implemented by a network entity, the method comprising:
- ungrouping traffic in a communication network from a defined connection comprising a plurality of input links onto a plurality of output streams, each input link carrying symbol blocks;
- wherein ungrouping the traffic comprises associating each symbol block received during a predetermined time interval with a corresponding output stream according to a one-to-one correspondence;
- and
- wherein the associating each of the symbol blocks received during the predetermined time interval comprises adapting to varying characteristics of at least one among the output streams and input links.
