Abstract: Techniques for maintaining service continuity in a 5G NR network in communication with a MEC system and an edge application (EDGEAPP) system are disclosed. A notification message originating from a service management function (SMF) of a core network (CN) is decoded at a network exposure function (NEF) of the CN. The notification message includes a UE IP address change of a UE. A private IP address of the UE is determined based on the UE IP address change. A query with the private IP address is encoded for transmission to a NAT server. A response from the NAT server is decoded. The response includes a public IP address and a UE ID of the UE. The public IP address corresponds to the private IP address. A tuple including the UE ID, the public IP address, and the private IP address is generated at the NEF.

Abstract: Methods and apparatus for software-controlled active-backup mode of link aggregation for RDMA and virtual functions. A Network Interface Controller (NIC) includes hardware implementing first and second physical functions (PFs) including transmit and receive resources to support data transfers via first and second ports. A bonding group is created with the first and second PFs. The first PF as an active PF and used for primary data transfers while implementing the second PF as a backup PF. On a link or port failure of the active PF, the bonding group is reconfigured to employ transmit and receive resources of the backup PF such that those resources are shared with the active PF. Data transfers are then performed using the shared resources of the active PF and the backup PF. Embodiments may support RDMA data transfers using PF bonding and the solution may be implemented in virtualized environments including virtual machines (VMs) in a manner transparent to the VMs.
