Working Group C

New directions in communication architectures and Technologies


Chair: Sudhir Dixit


The approach and focus of the WWRF is at present being sharpened to better align with the technology innovations and industry directions in networking and communication. As a result, the Working Group C, while building on its successes, is being revitalized to speed-up and facilitate the convergence of software, cloud, big data, virtualization and networking. It is the WGC’s endeavor to pool industry and academic resources to do targeted applied research to identify challenges facing the industry with this convergence and propose solutions that are pragmatic in the short-term (with backwards compatibility) and strategic in the long-term to evolve to what ideally they should be.


The group’s mission is to guide the mobile industry in the use of software, virtualization and cloud computing in future networks (both wireless and wired) by developing end-to-end network architectures, identifying the specific requirements and issues and addressing them by providing solutions that are practical and business driven, and thus accelerate the adoption of 5G where IT will play a major role. Virtual network slicing to develop custom networks for specific industry verticals and services from the common underlying physical infrastructure will also be an important mission of this group.

Until now the working focused on the vision and tasks that were guided by the architecture depicted in Figure 1 below, resulting into several widely cited white papers and outlooks. These accomplishments will now form the foundation of the future activities of the reorganized working group, as depicted in Figure 2.0, and will primarily focus on the softwarization, virtualization and slicing of the 5G and future networks where IT will play an important role.

Focused Topics

Main topics that WGC covers are focused on:

  • Software network architectures and software design approaches to meet the specific requirements of future wireless carrier networks
  • Mapping of 5G performance requirements to virtualized hardware and software that is decentralized, including potentially those that virtualize the user (5G) devices
  • Liaison with IEEE, ITU and ETSI and other fora to influence standards work
  • Facilitate collaborations and consensus building among various experts and actors
  • Invite and engage with the IT industry and encourage them to join WWRF
  • Organize speaking events and workshops to encourage dissemination and interactions with the experts
  • Convergent wireless/ wireline access and core network segments leveraging cloud, virtualization and big data
    • Smart Virtualized Infrastructure
    • Smart management of the Cloud-RAN;
    • Software-defined wireless networks (SDN);
    • Network Function Virtualization (NFV)
    • End-to-end network slicing
