The CARISMA ASON/GMPLS Network: Overview and Open Issues
The reduction of both deployment costs and operating expenses has emerged as a critical goal of next-generation optical networks. In this context, as each node maintains a large number of input/output ports (i.e. wavelengths, fibers, time slots ...), automation is needed to reduce long and tedious manual node configurations, thus easing network management and minimizing resource misconfiguration probability. In this paper, we present two novel mechanisms which permit GMPLS Link Management Protocol to deal with the resource discovery of all-optical meshed transport networks. The subsequent evaluation demonstrates their applicability over large meshed network topologies with considerably high nodal degrees.
