UK5G – The death of IP? Realising opportunities in Next Generation Protocols

Brought to you by CW (Cambridge Wireless)

This is a one-day workshop in Cambridge open to all those interested in the need to shift away from TCP/IP in 5G core and RAN.

About the event

This is a one-day workshop in Cambridge open to all those interested in the need to shift away from TCP/IP in 5G core and RAN.

  • The main challenges of the current technology include over-complex packet structure, poor mobility support and difficulty in supporting low latency applications.  
  • The main features of the new technology, expected to be in 3GPP Release 17, are (a) simplified packet headers through the movement of information into routing tables, and (b) offer separate synchronous and best-effort services.

 This event is suitable for engineers working on parts of the system that would be affected by a change away from TCP/IP in core and RAN (such as security, addressing, transport layer, slicing, SDN, NFV, MEC, Control and User Plane Separation, etc) to explore how they might benefit from switching to the new protocols, and what features of current protocols would need to be retained.

This event is in liaison with ETSI Next Generation Protocols Industry Strategy Group.

Welcome from Derek Long, Cambridge Consultants


Fraser Edwards, Cambridge Consultants - Why LTE didn't cut it for Ocado

Ocado is the world’s largest online only food distributor and developed the Ocado Smart Platform a fully integrated warehouse and logistics platform. A critical part of the platform is the communication system connecting the control element of the platform with the automated machinery used for collection and sorting of produce into totes ready for loading into the distribution network. The communications system must be wireless on account of the movable machinery and must be high performance as it operates in unlicensed spectrum and yet must provide very highly reliable communication so as to ensure full control. In this presentation we will describe the work we performed in the design of the system and some of the decisions that we made in order to develop the system and also key elements of the final system design and performance.


Q&A and discussion


Operators' requirements - Kevin Smith, Vodafone

The projected surge in connections, data consumption and mobility in the 5G era will place demanding requirements on networks - especially regarding performance, reliability and security. This step-change drives the need for next generation protocols to deliver these requirements with efficiency and scalability.


Q&A and discussion


Packet forwarding in NGP – John Grant

Changes in digital electronics since TCP/IP was created are outlined, and technology more appropriate to the 21st century, and to operators' requirements, is described. This provides two services; one is a synchronous service offering latency of a few microseconds per hop, to support applications requiring ultra-low latency as well as being the most convenient way to send continuous media such as audio and video. The other, which can use all capacity not used by the synchronous service, is a more traditional packet data service but with packet headers simplified by replacing per-flow information with a label which points directly to a routing-table entry; as well as reducing overheads this should greatly simplify the forwarding plane for SDN, and allows new kinds of addressing to be supported.

John Grant - Partner, Nine Tiles

John Grant chairs the ETSI Industry Strategy Group on Next Generation Protocols. He has been designing digital networks since 1981 when he created local area networking technology which was used in both industrial and commercial environments. Since then he has created products for carrying video and audio over digital networks, including network switching equipment; this has given him an insight into the requirements of audio and other live media, which are very different from those for data traffic. More recently he has been researching how packet networking can meet these requirements as well as avoiding the various problems that have been identified with IP. He is a Fellow of the Audio Engineering Society and chairs their standards subcommittee SC-02 on digital audio. He is also editor of several international standards documents including ISO TR 29181-3 (Future Network switching and routing).

Kevin Smith - Distinguished Engineer, Vodafone UK

Kevin Smith is a Distinguished Engineer, Vodafone Group. Kevin has worked with mobile Internet technologies since 1999, as a developer, enterprise architect and standards contributor. Since 2007 he has represented Vodafone at industry fora, including W3C, OMA, GSMA and IETF; and chaired several cross-operator and multi-vendor initiatives, including OneAPI and GSMA’s ENCRY and SMART groups. He chaired ETSI ISG NGP (Next Generation Protocols), 2016-17, driving the need for new Internet protocols that can securely sustain a broad range of 5G scenarios.
