15 Segregation of OAM and Replication Traffic Support (VNFM - V1)

This feature supports the following:
  • Separate network for OAM and Replication traffic
  • Supports DSR NOAM and Signaling VNFs.

Replication traffic is optional for a user where it can be used as either Inter-NE network (xmiRepl) or Intra-NE network (imiRepl) or Both or None. xmiRepl/imiRepl and xmi/imi supports Single, Dual, and Mix mode subnet, where both OAM and Replication service network can be on IPV4 or IPV6.

For Signaling VNF, it supports for all the following flavours:
  • DIAMETER
  • SBR
  • UDR
  • STP

In the scenario where both VNFM and VIM networks are in IPv6, user should ensure that both NOAM and Signaling have same replication network.

The user can configure the new xmiRepl and imiRepl in the same or different interface based on NOAM and Signaling VNFs.

While instantiating with xmiRepl/imiRepl, inside these the network address of the subnets are to be provided for the networks being used.

The following details must be provided only if the replication networks are in different cloud and not overlapping subnets or it it is applicable only for remote network addresses and not for local network addresses:
  • Noam contains - soamReplNetworkAddress/soamImiReplNetworkAddress , drNoamReplNetworkAddress/drNoamImiReplNetworkAddress
  • Signaling contains - noamReplNetworkAddress/noamImiReplNetworkAddress , drNoamReplNetworkAddress/drNoamImiReplNetworkAddress
  • DR-Noam contains - noamReplNetworkAddress/noamImiReplNetworkAddress
VNFM configures Services under Networking, based on the following user inputs:
  • If user input contains both xmiRepl and imiRepl.
    both

  • If user input contains only xmiRepl.
    xmi

  • If user input contains only imiRepl.
    imi

Note:

  • The networks used for all the interfaces (xmi, imi, imiRepl and xmiRepl) should be different.
  • Use only Public Networks for replication interfaces (xmiRepl and imiRepl).
  • The replication network address must be passed in the request body only if the replication networks are on different cloud and not overlapping subnets or for remote network addresses.
