TLDR
An orchestration system that comprises dynamic virtual function selection and intent-based traffic steering control functionalities to provide optimized service chains in terms of end-to-end latency and adjustable with respect to the context is demonstrated.Abstract:
This paper will demonstrate an orchestration system for 5G infrastructure supporting latency-minimized and self-adaptive service chaining over geographically distributed edge clouds interconnected through SDN. The demo will show an orchestration system that comprises dynamic virtual function selection and intent-based traffic steering control functionalities to provide optimized service chains in terms of end-to-end latency and adjustable with respect to the context (e.g., service dynamics, network status).read more

Tenant-defined service function chaining in a multi-site network slice
TL;DR: In this article, the authors proposed a VNF selection algorithm that relies on an abstracted network model to minimize topological and monitoring information required by the infrastructure, and also proposed a forwarding mechanism that manages chains and controls traffic steering within the tenant network without leveraging infrastructure control APIs.
