These software features have been
introduced in Release 5.2.4:
ODU and ODU Cross Conections
In the case of channelization, ODU is created as a sub controller of
an OTU controller Optical Channel Data unit (ODU ) allows you to support tandem
connection monitoring (TCM), path monitoring (PM) and automatic protection
switching (APS) of OTN traffic.End-to-end path supervision and client
adaptation is made possible by using the OPU. The ODU provides two important
overheads : the PM overhead and the TCM.
Open Shortest Path First (OSPF) is a routing protocol designed to run
an autonomous system. It maintains an identical database describing the
topology of an autonomous system. From the identical database, a shortest
path-tree calculates the routing table. OSPF-TE allows controlling the data
Based on definitions for G.709, the following payloads are supported:
Tandem Connection Monitoring
Tandem Connection Monitoring (TCM) application is performed at ODUk
layer, some bytes of the overhead are reserved for applications.
TCM application allows you to setup and monitor the Trail Trace
Identifier (TTI) as well as the BIP-8 error monitoring to receive alarms or
Based on definitions for G.709, the following multiplex containers are
Multiplex Mapping and Rate Adaptation
Based on definitions for G.709, the following multiplex mapping and
rate adaptation are supported:
Based on definitions for G.709, the following are supported:
General Communication Channel (GCC) is an in-band side channel that
carries transmission management and signaling information within optical
transport network elements. Maximum 30 channels are supported in GCC links.
In-Service Software Upgrade (ISSU) is a technique used to update the
software packages on a network device without affecting the traffic. By using
ISSU, you can apply bug fixes and deploy new features and services of the
complete Cisco IOS XR Software image.
Generalized Multi-Protocol Label Switching (GMPLS) allows to define
and view the fiber and alien wavelength parameters that are used during GMPLS
circuit creation. It ranges the packet based data on MPLS protocol to allow the
creation and maintenance of channels across the networks. It contains
non-packet switching devices.
