Overview

A network service chaining (SC or SFC), is a capability that uses SDN capabilities to create a service chain of connected network services and connect them in a virtual chain. This capability can be used by SP to set up catalogs of connected services that enable the use of a single network connection for many services, with different characteristics.

Dublin Goals

1. Enhancements to Information & Data Model - Extend CCVPN IM &DM for DR services
2. Enhancements to DR compliant validation when on-boarding - Extend the existing validation for lifetime compliance validation
3. DR Activation/Configuration -  enable DR awareness when provisioning and operations a NS
4. Direct Service Recovering - Implementation of DR service across domains to provide fine granularity management during the elapse time
5. Recovering Status Notification - Notify to service administrators that the Service has been recovering or progress in the service bus

6. Smart workload balancing - smart optimization and selection when recovering for connection reliability and efficiency

7. Future Releases (El Alto and beyond)
   
   1. Intent programming based trigger and receiver
   2. Predicability based optimization
   3. VPN as a service

Business Requirement

DR Services are used by Operators to connect different Cloud for DR usage. For example, multiple Cloud Consumers can connect with different Clouds for replication/recovery between different domains/sites.  

Participating Companies

Wind River, Huawei,ZTE

Scope

The Dublin version will focus on the enabling of basic features. If possible, we can also try to complete the intelligent modeling of SFC at SDC.
