Abstract: A method, computer program product, and computing system for selecting target volumes within a storage system that are currently accessible to computing devices via first storage protocol paths via a first storage protocol for accessing via second storage protocol paths via a second storage protocol. For each of the selected target volumes, a first storage protocol identifier specific to each selected target volume may be associated with a second storage protocol identifier specific to each selected target volume. The first storage protocol paths and the second storage protocol paths may be grouped into a multipath group based upon the association between the first storage protocol identifier and the second storage protocol identifier. Access between the computing devices and the selected target volumes may be switched from the first storage protocol paths to the second storage protocol paths without application disruption and across multiple host platforms, including host-clusters.

Abstract: The present disclosure relates to blockchain-based data processing methods and devices to achieve balance between a service need and system resource consumption. In one example method, an amount of service data processed by consensus in a blockchain in a specified time period is monitored. A determination is made as to whether the monitored amount of processed service data in the specified time period is less than a specified first threshold or more than a specified second threshold. In response to determining that the monitored amount of processed service data in the specified time period is less than the specified first threshold or more than the specified second threshold, a block generation time for the blockchain is dynamically adjusted. A new block in the blockchain is then dynamically adjusted based on the adjusted block generation time.

Abstract: A method for referencing and updating objects in a shared resource environment. A reference counter counts is incremented for every use of an object subtype in a session and decremented for every release of an object subtype in a session. A session counter is incremented upon the first instance of fetching an object type into a session cache and decremented upon having no instances of the object type in use in the session. When both the reference counter and the session counter are zero, the object type may be removed from the cache. When the object type needs to be updated, it is cloned into a local cache, and changes are made on the local copy. The global cache is then locked to all other users, the original object type is detached, and the cloned object type is swapped into the global cache, after which the global cache in unlocked.

Abstract: A method for context-dependent in-call video codec switching includes receiving an indication that a far-side endpoint includes a capability to switch from an initial video codec to a secondary video codec during a call. During a call with the far-side endpoint, the method includes determining that a performance of an encoder satisfies a codec switching threshold. The codec switching threshold indicates that the performance of the encoder justifies switching from the initial video codec mid-stream of the call. During a call with the far-side endpoint, the method also includes switching from the initial video codec initially negotiated to govern the call to the secondary video codec.

Abstract: Systems and methods for dynamic service-based load balancing in an SD-WAN are provided. According to one embodiment, a routing protocol daemon of an SDN controller within a spoke network receives a dynamically assigned subnet and associated attributes for a client device newly registered with the hub network. The routing protocol daemon tags the subnet with a route tag using a route map based on the received attributes meeting network administrator-defined match criteria for corresponding attributes associated with the route tag in the route map. The tagged subnet is communicated to an SD-WAN daemon of the SDN controller, which translates an SD-WAN service rule defined with reference to the route tag to an SD-WAN service rule defined with reference to the subnet. A load balancer associated with the spoke network is caused to perform load balancing of incoming network traffic in accordance with the translated SD-WAN service rule.
