A.3. An OEO Switch with DWDM Optics A.3. An OEO Switch with DWDM Optics
Figure 2 shows an electronic switch fabric surrounded by DWDM Figure 2 shows an electronic switch fabric surrounded by DWDM
optics. In this example the electronic fabric can handle either optics. In this example the electronic fabric can handle either
G.709 or SDH signals only (2.5 or 10 Gbps). To describe this node, G.709 or SDH signals only (2.5 or 10 Gbps). To describe this node,
the following information is needed: the following information is needed:
<Node_Info> ::= <Node_ID>[Other GMPLS sub- <Node_Info> ::= <Node_ID>[Other GMPLS info-
TLVs][<ConnectivityMatrix>...] [<ResourcePool>][<RBPoolState>] elements][<ConnectivityMatrix>...] [<ResourcePool>][<RBPoolState>]
In this case there is complete port to port connectivity so the In this case there is complete port to port connectivity so the
<ConnectivityMatrix> is not required. In addition since there are <ConnectivityMatrix> is not required. In addition since there are
sufficient ports to handle all wavelength signals the <RBPoolState> sufficient ports to handle all wavelength signals the <RBPoolState>
element is not needed. element is not needed.
Hence the attention will be focused on the <ResourcePool> sub-TLV: Hence the attention will be focused on the <ResourcePool> field:
<ResourcePool> ::= <ResourcePool> ::=
<ResourceBlockInfo>[<RBAccessibility>...][<ResourceWaveConstraints>. <ResourceBlockInfo>[<RBAccessibility>...][<ResourceWaveConstraints>.
