I’m just back from cold and rainy Berlin, where I chaired the second Network Slicing Summit, held 23 October 2018 at the Messe as part of the large annual Broadband World Forum. Like last year, 50+ people attended the Network Slicing Summit, but unlike last year, the event was totally standalone (it was a pre-SON World event last year). We had a well-balanced mix of standards bodies (e.g., 3GPP, ETSI, IEEE), trade bodies (GSMA and 5G-ACIA), academia (e.g., Cork Institute of Technology, University of Peloponnese), regulatory bodies (e.g., Ofcom), and service providers including BT, Bell Canada, Deutsche Telekom, KDDI, NTT DOCOMO, Swisscom, Telenor, Telefónica, Telia, Turk Telecom, and Vodafone. And of course, we ended up with as many definitions of network slicing as people in the room! Coined by our SDN and NFV research leader Michael Howard, here is our end-to-end network slice definition: “An end-to-end network slice is a logical partition or a virtual piece of a physical network, including fixed and mobile, physical and virtual, that has connections, capacities (bandwidth), and characteristics (e.g., SLAs) that make the slice look and act like a physical network to the user, program, or process that is using it.” Clients, please log in to view the full content.
