Scenario

The SBC supports encryption across Network-Network Interfaces.

Background Information

Description

SBC support for NNI encryption

  • Communication between servers within the core side of the network is typically trusted and usually clear-text/un-encrypted, even if it was originally encrypted at the edge.
  • On the interconnect side of the SBCs, the remote peers may or may not be trusted. Some interfaces maybe in clear text/un-encrypted, others may use IPsec or TLS to protect the interface. Scaling is much less of a concern than at the access side as there are typically far fewer peers.
