Abstract
A forwarding node decapsulates and encapsulates data. The decapsulation may be performed using pattern matching techniques and the encapsulation may be performed using pattern insertion techniques. The decapsulation and encapsulation are preferably performed by hardware devices such as application specific integrated circuits (ASICs) to enhance the speed of such operations. The decapsulation and encapsulation may be independent of each other and performed on a per virtual circuit basis.
Claims21
A system comprising:
- a processor to:
- receive a synchronous optical network (SONET) data stream;
- separate the SONET data stream into a plurality of data streams,
- a particular data stream, of the plurality of data streams, including:
- a data stream of a first type, and
- a data stream of a second type that is different than the first type,
- the data stream of the first type including a packet over SONET (POS) data stream;
- and
- process the plurality of data streams.
A method comprising:
- receiving, by one or more devices, a synchronous optical network (SONET) data stream;
- separating, by one or more devices, the SONET data stream into a plurality of data streams, the plurality of data streams including:
- a data stream of a first type,
- the data stream of the first type including a packet over SONET (POS) data stream, and
- a data stream of a second type that is different than the first type;
- and
- processing, by one or more devices, the plurality of data streams,
- processing the plurality of data streams including:
- performing first processing on the data stream of the first type;
- and
- performing second processing on the data stream of the second type,
- the first processing being different than the second processing.
A system comprising:
- one or more devices to:
- combine a plurality of data streams into a single synchronous optical network (SONET) data stream,
- the single SONET data stream including:
- a data stream of a first type,
- the data stream of the first type including a packet over synchronous optical network (POS) data stream, and
- a data stream of a second type that is different than the first type, and
- transmit the single SONET data stream.
