Current Requirement

The VNF SHOULD support network segregation, i.e., separation of OA&M traffic from signaling and payload traffic, using technologies such as VPN and VLAN.

Proposed Requirement

The VNF SHOULD support the separation of (1) signaling and payload traffic (i.e., customer facing traffic), (2) operations, administration and management traffic, and (3) internal VNF traffic (i.e., east-west traffic such as storage access) using tech technologies such as VPN and VLAN.
