Configuration Guide for Cisco NCS 4000 Series

Understand OTN Circuits

An OTN circuit provides the ability to aggregate different types of traffic such as Ethernet, SONET or SDH, and packet over OTN at different data rates such as 1.25, 2.5, 10, or 100 GBit per second. This aggregated traffic is transported by network elements that acts as OTN cross connections.

ODUk controllers can be cross connected with controllers of the same rate in an OTN circuit by a fabric card. The following network applications are associated with OTN network elements:

End-to-end circuits from any rate or any payload client service
End-to-end circuit from a client service versus the OTN (OTUk) network
Aggregation of OTN traffic (OTUk)

Understand Circuit Diversity

This feature enables the user to create a circuit diverse of another circuit. A diverse circuit is a circuit that takes a path based on certain diversity conditions.

When request for creating a diverse circuit is received the system first tries to find a SRLG diverse path. If SRLG diverse path is not available then it falls to Node and Link diversity and if this also fails then basic Link diverse path is used. It is also possible to enable diversity on an existing circuit but this will trigger re-signaling of the circuit.

Following are the restrictions applicable to this feature (not applicable for UNI circuits) :

The diverse circuit has the same head node.
The feature is supported only for 1+0 circuits.
Strict diversity is supported i.e. if a diverse path is not found, the circuit is not created.

Understand OSPF

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 packet's path.

OSPF provides following features:

Routing of area.
Routing of protection.
Minimizing the routing protocol traffic.

Understand MPLS TE

MPLS TE learns the topology and resources available in a network and then maps traffic flows to respective paths based on resource requirements and network resources, for example, bandwidth. MPLS TE builds a unidirectional tunnel from a source to a destination in the form of a label switched path (LSP), which is then used to forward traffic. Tunnel head end or tunnel source is the point where the tunnel begins, the tunnel tail end or tunnel destination is the node where the tunnel ends .

Understand Tandem Connection Monitoring

Tandem Connection Monitoring (TCM) layer is used for protection applications, for example, APS. In traditional SONET/SDH applications, the path layer is used for this purpose, however, it can be influenced by errors that occur outside a given operators network and cause undesired protection switch events to occur within their network. Since TCM can isolate a service to a given domain, it can be used to trigger protection applications and avoid such issues.

Understand ISSU Upgrade

In-Service Software Upgrade (ISSU) is a technique that updates the software packages on a network element without affecting the traffic. By using ISSU, you can deploy new Cisco IOS XR Software images that supports new software features and services. The Cisco IOS XR ISSU capability extends Cisco high availability innovations for minimizing planned downtime for service provider networks.

Understand GCC Management

General Communication Channel (GCC) is an in-band side channel that carries transmission management and signaling information within optical transport network elements.

There are two types of GCC links:

GCC0 - two bytes within OTUk overhead.
GCC1 - two bytes within ODUk overhead.

Understand GMPLS

Generalized Multi-Protocol Label Switching (GMPLS) extends the packet based MPLS protocol to allow creation and maintenance of tunnels across the networks that consist of non-packet switching devices. GMPLS tunnels can traverse the Time-Division Multiplex (TDM) interface and switching types.

The following protocols are associated with GMPLS:

OSPF
OSPF-TE
RSVP-TE
MPLS-TE
LMP

Understand Explicit Path

Explicit path refers to a user defined path taken by a circuit. GMPLS dynamically determines the path to be taken by a circuit but user can override this path by configuring an explicit path.

GMPLS Optical Channel Trail

The user can create a GMPLS optical channel trail (OCH Trail) in a network where the NCS 4000 series node is connected to a ONS 15454, ONS 15454 M2, or ONS 15454 M6 nodes. The OCH trail circuit originates from a NCS4k-2H-W interface on the source NCS 4000 node and terminates on the NCS4k-2H-W interface on the destination NCS 4000 node to create an optical connection. The prerequisite for the OCH trail circuit is to create a Link Management Protocol (LMP) link between the NCS4k-2H-W interface on the NCS 4000 node and the optical channel Add/Drop interface on the ONS 15454, ONS 15454 M2, or ONS 15454 M6 nodes.

The OCH Trail circuit is used to transmit traffic over a long distance. The traffic transmitted by the OCH Trail circuit is used as a OTU link by the OTN layer to route the OTN circuit.
