Workshop Bio
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.
Topics
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.
