Call for Papers: Managing Radio Networks in an Encrypted World (MaRNEW) Workshop

Managing Radio Networks in an Encrypted World (MaRNEW) Workshop

Thursday 24th – Friday 25th September, 2015, 9:00 AM – 6:00 PM
AT&T Atlanta, Atlanta, GA

Mobile networks have a set of requirements and properties which places a  large emphasis on sophisticated bandwidth optimization. Encryption is  increasing on the internet which is a good thing for consumer and  business privacy and security. Many existing mobile bandwidth  optimization solutions primarily operate on non-encrypted  communications; this can lead to performance issues being amplified on  mobile networks. Encryption on networks will continue to increase; and  with this understanding the workshop aims to understand how we can solve  the issues of bandwidth optimization and performance on radio networks  in this encrypted world.

Understanding “Bandwidth Optimization”

For the purposes of this workshop, bandwidth optimization encompasses a variety of technical topics related to traffic engineering,  prioritisation, optimisation, efficiency enhancements, as well as user-related topics such as specific subscription or billing models. These  can include:

  • Caching
  • Prioritisation of interactive traffic over background traffic,
  • Per-user bandwidth limits
  • Business-related topics such as content delivery arrangements with specific content providers.

Many of these functions can continue as they’re performed today, even  with more encryption. Others traditionally inspect parts of the  communication that are encrypted, and will have to be done differently  in a more-encrypted Internet.

Finally, while not strictly speaking traffic management, some networks  employ policy-based filtering (e.g., requested parental controls) and  all networks support some form of legal interception functionality per applicable laws.


For this workshop we would like to consider topics that speak to these questions, including the following:

  • Understanding the bandwidth optimization use cases particular to radio networks
  • Understanding existing approaches and how these do not work with encrypted traffic
  • Understanding reasons why the Internet has not standardised support for LI and why mobile networks have
  • Determining how to match traffic types with bandwidth optimization methods
  • Discussing minimal information to be shared to manage networks but ensure user security and privacy
  • Developing new bandwidth optimization techniques and protocols within these new constraints
  • Discussing the appropriate network layer(s) for each management function
  • Cooperative methods of bandwidth optimization and issues associated with these

The outcome of the workshop will be architectural and engineering  guidance on future work in the area, published as an IAB workshop  report, based on discussion of proposed approaches. We will also explore  possible areas for standardization, e.g. new protocols that can aid  bandwidth optimization whilst ensuring user security inline with new  work in the transport layer.

Submission Instructions:

Attendance at the workshop is by invitation. Prospective participants are invited to submit short (i.e., about two pages) position papers outlining their views on one or more topics related to the scope of the workshop.  Position papers will be published on the IAB website at
