One or more aspects of the present disclosure relate to detecting and mitigating congestion in a storage area network. In embodiments, peer congestion Fabric Performance Impact Notification (FPIN) messages can be used to infer congestion on a target port that has not received a direct congestion FPIN. Upon receiving a peer congestion FPIN for a target port, the embodiments determine if the target port received a direct congestion FPIN. If not, the embodiments infer congestion on the target port based on the peer notification. The embodiments then control messaging to the congested port to mitigate the congestion, such as by adjusting bandwidth limits. This approach enables congestion detection and mitigation even when severe congestion prevents the delivery of direct notifications to the affected port. Accordingly, the embodiments leverage existing FPIN infrastructure and connectivity information to provide a simple, standards-based solution for identifying and addressing congestion issues in storage networks.

Solutions are disclosed that provide for internet protocol (IP) multimedia subsystem (IMS) session continuity with stored authentication. When a user equipment (UE) registers with a first proxy call session control function (P-CSCF), the first P-CSCF stores authentication information for the UE, and binding information for an IMS session in an authentication database, for example in a storage area network (SAN). Upon an outage of the first P-CSCF, a second P-CSCF (in the same pool) retrieves the authentication information and binding information in lieu of requiring the UE to register. The second P-CSCF is then able to act as a proxy for the IMS session. This is available for mobile originating (MO) and mobile terminating (MT) calls. For MO calls, the call setup is sped up. For MT calls, the UE is able to receive the call, rather than the call being missed.
