Edge Network Support

Edge networking is one of the most promising concepts, regarding the reduction of end-to-end service delay and network congestion. It posits that network functions are placed as close as possible to the mobile devices, in order to be able to support the shortest data paths (related to delay and number of intermediary nodes), while avoiding inefficient functions relocations, which may be often required for ultra-dynamic devices.

Apart from the development of the fundamental mechanisms for supporting infrastructure based shortest data paths, which are included in Open5GCore Rel. 1, several research items have to be further resolved:
  • Network functions placement;
  • Clustering of the end point devices based on their mobility. Extensions of the subscription profile for edge networking;
  • Policy based function of edge networking for making decisions when edge routing has to be used;
  • Autonomic functioning of edge nodes when there is no backhaul available;
  • Selection of the backhaul and of the connectivity parameters depending on the specific sessions;
  • Dynamic control entities selection – dynamic switching between edge and core network control;
  • Dynamic data path support – support for data path switches chaining.
