GMPLS Interface Switching Capability Descriptor
An
ISC value is advertised as part of the
Interface Switching Capability Descriptor attribute (
sub-TLV) of a TE interface.
Apart from the ISC the ISCD contains the encoding type, the bandwidth granularity, the unreserved bandwidth on each of eight priorities.
The ISCD does not identify network layers, it uniquely characterizes information associated to one or more network layers.
TE link end advertisements may contain multiple ISCDs, this can be interpreted as advertising a multi-layer (or multi-switching) TE link end. That is, the TE link end is present in multiple-layers.
If a node has multiple switching capabilities it is either a
simplex node or a
hybrid node.
