Name of Use Case: vEPC


Use cas authors:

Orange

Description:

Extend EPC capabilities with vSGW and vPGW. Demonstrate how to use a hybrid (PNF+VNF) solution using ONAP


Version 0: no automatic legacy configuration. Deployment on a single OpenStack data-center based with no SDNC

Version 1: only configure legacy MME.  Deployment based on a single OpenStack data-center based with no SDNC

Version 2: configure the full EPC (legacy+virtualised) functions on 2 OpenStack data-centers using SDNC


VNF should be compliant with APP-C and DCAE using Netong/Yang for configuration and VES or SNMP for event collections


Deployment phase

The ONAP-operating deploys the vEPC service.

As a result, one vSGW and one vPGW are deployed using SO and APP-C and updating AAI.


Closed loop

Triggered on a number of sessions, the policy engine executes the rule that triggers the SO to instantiate a new vPGW and will the APP-C to configure both the vPGW and the MME.


V0

On-boarding/Design phase

The ONAP designer onboards the VNF descriptors, define the Directed Graphs for the 2 VNF and the legacy MME for configuration and defines the service.

The ONAP designer defines a simple policy rule: to scale vPGW on the basis of the number of sessions and configure the MME to take into account the new vPGW

Users and benefits:

SPs benefit from vEPCuse case in the following aspects:

  1. service agility: more easy design of both VNF and network service, VNF onboarding, and agile service deployment.
  2. resource efficiency: through ONAP platform, the resource can be utilized more efficiently, as the services are deployed and scaled automatically on demand.
  3. operation automation and intelligence: through ONAP platform, especially integration with DCAE and policy framework, vEPC VNFs and the service as a whole are expected to be managed with much less human interference and therefore will be more robust and intelligent.

vEPC users benefit from the network service provided by SPs via ONAP, as their user experience will be improved, especially during the peak period of traffic
