Abstract:
In 5G, the latency and bandwidth requirements of demanding scenarios such as virtual and augmented lead to significant design challenges. This need is complemented by the adoption of cloud principles for providing services, particularly for virtualizing service components with which virtualized instances can appear rapidly at different execution points in the network. The solution seems simple - provide service endpoints close to the end user, but early service break-out is currently limited to routing requests to Point-of-Presence (POP) nodes provided by a few global CDN players deep in the customer network. In the work reported here, we propose instead to turn the edge of the Internet into a rich service-based routing infrastructure with early service termination provided through edge compute nodes. Our approach interprets every IP-based service as a named service over a (L2 or similar) transport network. This requires no per flow state in the network, while natively supporting both unicast and multicast delivery, even for transactions that are defined with unicast semantic. In addition, it enables route adjustments in time scales of few tens of milliseconds, enabling rapid failure recovery, extremely responsive load balancing, efficient mobility support, and more. We have implemented our solution on standard SDN-based infrastructure and in mobile terminals in a backwards-compatible manner. Our performance evaluation shows significant improvements in network utilization as well as flow setup times.
