Abstract: A system is disclosed for providing Open RAN CU-UP high availability, the system comprising: at least one active CU-CP; at least one active CU-UP in communication with the at least one active CU-CP; and at least one standby CU-UP in communication with the at least one active CU-CP; wherein when a message may be received from a CU-CP that detects a failure of the at least one active CU-UP, the at least one standby CU-UP may be configured to take over and become an active CU-UP, thereby providing failover redundancy for the at least one active CU-UP.

Abstract: A method and computer readable medium for providing accelerated lookup for ESP IPsec tunnels is presented. In one embodiment a method includes receiving an IP packet at a network stack; performing IPsec policy lookup of the IP packet to identify an ESP tunnel IP, thereby ensuring an inner IP is routable at an other end of the tunnel without installing a route for the inner IP at the network stack; performing a route lookup for the tunnel IP; and sending the IP packet across the ESP tunnel.
