Massive number of call attempts (roughly 60-fold increase) were made. Call restriction control were in place.

We need a mean to do resource sharing

Challenges

Standardization won’t be completed before deployment – Risk of ‘standalone’ specification

Lack of commercial virtualization-based solution – gaps exist between standards and what is available

Don’t have a reference platform – Can’t compare if an offered platform is good enough

We need a way for fast implementation, start with what is common to everyone. We have heard that ‘opensource’ is pretty fast ….

Standard and Opensource

Open Platform for NFV started in Oct. 2014

Use cases and requirements Architecture High-level specifications

Open Platform for NFV A Linux Foundation Collaborative Project

Reference implementation Interoperability tests Validating specifications

requirements

solutions

11

Network Functions Virtualisation (NFV) Industry Specification Group (ISG)

What we want and the interoperability requirements

We quickly know what is missing, what is right




Contribution of Opensource

De-facto implementation – Opensource projects can provide fast solutions becoming de-facto/standards later

Validity and compliance

– detects issues in standards through implementation, provide common codebase to test compliance to the standards

Reduce development burden – vendors can build on existing code base rather than creating it from scratch

Summary

Telco nodes need ‘some’ attention in virtualization. reliability, high availability required, but not from the hardware per-say.

Opensource can play a significant role in NFV-based telco network deployment and the

consequent operation. complementing the lack of commercial solutions.

OPNFV is a fast-growing opensource community driving speedy development of a reference

NFV platform. heavy presence of telco players. Seeing success already.

Early engagement from Operators/service providers in opensource development saves lots

of rework later. collect end-customers view ASAP.

Follow standards. Standard is necessary in communication.

opensource can accelerate the adoption of telecom standards.
