The present invention relates to communications methods and apparatus for session load balancing among session processing entities. An exemplary method embodiment includes the steps of receiving from a first device at a Signaling Front End Load Balancer (SLB) a first session initiation request destined for a second device; making a first session load balancing decision at the SLB with respect to the received first session initiation request; transmitting the first session initiation request to a first Session Border Controller (SBC) worker based on the first load balancing decision, the first SBC worker being one of a plurality of SBC workers forming a cluster of SBC workers, making a session mismatch determination at the first SBC worker with respect to a first session corresponding to the first session initiation request; and when the session mismatch determination is that a session mismatch has occurred notifying the SLB of the session mismatch.

An exemplary embodiment of implementing a communications service in a Public Cloud system comprises the steps of: (i) registering, by a Maintenance Management application of the communications service, to receive notifications for maintenance events scheduled for virtual machines and/or servers of the Public Cloud system being used to implement the communications service; (ii) receiving, by the Maintenance Management application, a maintenance notification indicating a first virtual machine is to undergo a maintenance event; (iii) determining, by the Maintenance Management application, public IP addresses being hosted by a first Packet Front End application executing on the first virtual machine; and (iv) notifying session control applications of the communications service to drain the determined public IP addresses being hosted by the first Packet Front End application.

Methods and systems for supporting parallel processing utilizing Central Processing Unit(s) (CPU(s)) and at least one Graphics Processing Unit (GPU) device to provide high scale processing of content streams. An exemplary method embodiment including the steps of: receiving at a CPU multiple data units corresponding to a first frame time for each of first through Nth content streams; sequentially processing by the CPU data units corresponding to different content streams and the first frame time; operating a set of cores of a GPU, in parallel, to perform processing on a set of data units, processing including operating each core of the set of cores to perform an operation on a data unit corresponding to a single one of the first plurality of content streams, each core in the set of cores processing a data unit of a different content stream, said processing generating a set of generated data units.

Methods and apparatus for supporting encoding, decoding and/or transcoding of content streams in a communication system

Context values used by filters corresponding to different streams are stored in an interleaved manner in a block of contiguous memory locations, e.g., of a buffer, to facilitate coalesced access of data units, e.g., context values, corresponding to different channels to facilitate filtering of multiple streams, e.g., audio streams, in parallel using a graphics processing unit. Context values corresponding to different channels are intentionally grouped together on an interleaved per channel basis in staging memory. This allows context values for multiple different streams to be transferred, e.g., loaded, as a single block e.g., with a context value of each different channel being loaded into a different GPU core. By organizing the context values to facilitate GPU processing, device operation is improved and execution efficiency is achieved as compared to what would be the case if multiple non-contiguous memory locations had to be implemented to load the cores of the GPU.
