Abstract: Embodiments herein describe branch statements for a segment routing (SR) list that are inserted into a packet header for use when performing Service function chaining (SFC). For example, the branch statement may be embedded within a SR list and includes a serverless function ID and two different segment IDs (SIDs). When reaching a network node assigned to perform the serverless function, the node uses the function ID to determine the appropriate serverless function to use when evaluating the packet and then uses the results of that function to determine which segment to use when forwarding the packet. Thus, rather than forming a linear chain, the branch statement permits the SR list to form different routes (depending on the results of the serverless function) as part of SFC.

Abstract: Systems, methods, and computer program products relating to resilient transmission of a media stream over a communication network. A plurality of data packets are received over a communications network. The plurality of data packets relate to a first source video portion transformed using a geometric transform. The geometric transform is configured to modify a location of pixels in the first source video portion such that a plurality of adjacent pixels in the first source video portion are not adjacent after transformation. A received video portion is assembled based on the plurality of data packets. The received video portion is transformed, using an inverse of the geometric transform, to generate a second source video portion. The second source video portion and the first source video portion include a plurality of matching pixels.
