Congress in NFV-based Mobile Cellular Network Fault Recovery

High service availability is an integral part in mobile core network. As each core node hosts few hundred thousand subscriber sessions, a sub-second level fast recovery is necessary not only to ensure seamless connectivity to the customers, but also to avoid the consequent ‘attach’ storm where all disconnected mobile devices try to reconnect to the mobile network simultaneously, creating control traffic beyond what a node can handle. In NFV-based networks, recovery actions will be performed by a node manager which cannot directly detect virtualized network infrastructure level failures. Therefore, OpenStack needs to detect and notify the corresponding node manager of relevant resource failure. An additional requirement is the filtering of the failures, as the definition of failure and the operational policy may differ among Operators.

We’ll introduce a solution using Congress and extended features to meet these telco requirements, as well as PoC developed with OPNFV Doctor Project.


The Telecom/NFV track is brought to you by OpenStack and OPNFV.

What can I expect to learn?
  • Details use cases and the consequent requirements for failure management in a mobile cellular network, from NFV-based network design, development and deployment experience on OpenStack
  • How Congress can play a vital role in meeting such failure management requirements
  • On-going progress and success story of collaboration among operators, telco-vendors and open source developers in OpenStack and OPNFV

I have been working in the Telco industry since 1998. Watching the industry to evolve and being part of making it happen. 2014 I started to work in the OPNFV to make Telco/NFV features to open source. My main focus is to drive changes into OpenStack . Figure out with developers, operators and OPNFV community of how things can be done to satisfy Telco and other users needs. Discuss,... FULL PROFILE
