Abstract
A system, device, and method for localized information processing in a multiprotocol label switching network enables one or more intermediate devices to process locally significant information in certain packets. Each locally significant packet includes a local significance indicator and optionally includes a processed indicator indicating whether or not the packet has been locally processed. A designated intermediate device decides whether to locally process the packet based upon the local significance indicator and optionally the processed indicator.
Claims21
method for localized information processing by an intermediate device in a multiprotocol label switching network, the method comprising:
- receiving a label switched packet including a label having a label field and at least one local significance indicator, the local significance indicator indicating that the packet contains locally significant information other than the label field;
- and
- deciding whether to locally process the locally significant information based upon the at least one local significance indicator.
A device for localized information processing in a multiprotocol label switching network, the device comprising:
- receiving logic operably coupled to receive a label switched packet including a label having a label field and at least one local significance indicator, the local significance indicator indicating that the packet contains locally significant information other than the label field;
- and
- decision logic operably coupled to decide whether to locally process the locally significant information based upon the at least one local significance indicator.
A communication system comprising a plurality of label switching devices, wherein at least one label switching device is designated to process locally significant label switched packets based upon at least one local significance indicator in each of said locally significant label switched packets, the local significance indicator being indicative of locally significant information other than a label field.
