• Proposed name for the project: Rescuer
• Proposed name for the repository: rescuer
• Project Categories: Requirement

Disaster Recovery (DR) is a very important issue in NFV, as when a VIM instance or even a complete site goes down, we need a strong DR scheme to keep the service continuity to meet the requirement defined by the terms like RPO or RTO.

Policy and infrastructure support are the two main aspects of DR, where the former one is out of the scope of OPNFV, this project focus on the latter area.

• Describe the problem being solved by project

The project aims to develop the requirements for NFVI and VIM on supporting Telco grade DR implementation which covers :

• Requirements for VIM and NFVI to support Single Site DR, including both active-active and active-standby design
• Requirements for VIM and NFVI to support Multisite DR, including both active-active and active-standby design
• ..

The requirements would cover DR for compute, storage and network.

• Specify any interface/API specification proposed

New DR related API specification would be proposed.

• Identity a list of features and functionality will be developed.

1. Requirements for infrastructure to support Telco grade DR implementation
2. Use Cases for infrastructure level support Telco grade DR implementation
3. Upstream feature development according to the developed requirements.

• Identify what is in or out of scope. So during the development phase, it helps reduce discussion.

In scope: infrastructure level support for Telco grade DR implementation

Out of scope: DR Policy making, MANO level DR.

• Describe how the project is extensible in future

This project is extendable for future functions.

N/A.

This project intends to produce the following documentation supporting the meta distribution:

• Installation Guide
• User Guide

OpenStack

It would be aligned with OpenStack release schedule (per cycle) and OPNFV schedule.

• Identify any specific development be staged with respect to the upstream project and releases.

N/A

• Are there any external fora or standard development organization dependencies. If possible, list and informative and normative reference specifications.
