15.9.3 LMP WDM
15.9.3 LMP WDM
LMP manages traffic engineering links between peer nodes (nodes that are peers in signaling and/or
routing). The purpose of the LMP WDM extensions
1
is to allow LMP to be used between an OXC node
and an adjacent DWDM OLS node. Figure 15-31 illustrates the relationship between LMP and
LMP-WDM. OXC 1 and OXC 2 are peer nodes whose control channel is managed with LMP.
LMP-WDM manages the control channel between an OXC node and an OLS node.
Figure 15-31 LMP and LMP-WDM Relationship
When the two OLS nodes can communicate their configuration and the current state of their optical link
to the two peer nodes (OXC 1 and OXC 2) through LMP-WDM, network usability is improved through
the reduction of manual configuration and enhanced fault detection and recovery.
15.9.4 LMP Network Implementation
Figure 15-32 shows a network-level LMP implementation. It is an IP-plus-optical network, with
end-to-end routing based on MPLS and GMPLS. The primary network components are:
Routers
Cisco Carrier Router System (CSR)
Cisco Gigabit Switch Router (GSR)
An OXC node
Ultra long-haul (ULH) DWDM equipment
LMP and other features allow the Cisco ONS 15454 DWDM node to fulfill the ULH DWDM role.
Figure 15-32 illustrates the relationship between the network components.
1. LMP-WDM extensions that allow management of links between a peer node and an adjacent OLS node are
described in the following IETF document: Internet-Draft, draft-ietf-ccamp-lmp-wdm-03.txt, published as a
Proposed Standard, RFC 4209 (http://www.ietf.org/rfc/rfc4209.txt), 2005-11-1
