Abstract: Various example embodiments for supporting scheduling of deterministic flows in time synchronized networks are presented. Various example embodiments for supporting scheduling of deterministic flows in a time synchronized network may be configured to support scheduling of deterministic flows in the time synchronized network based on assignment of transmission start times to data flows of communication devices such that the communication devices may transmit data of the data flows at the transmission start times in a manner tending to reduce or eliminate collisions in the time synchronized network.

Abstract: A segment routing (SR) network has a plurality of interconnected SR gateways, where each of a plurality of local networks is connectable to an SR gateway at an edge router of the local network. An SR network control plane maintains a locator database that maps (i) a global IP (GIP) address for user equipment (UE) to (ii) an IP address of a downstream node associated with the UE along a path from the SR network to the UE. An SR gateway (i) receives a message for the UE and (ii) addresses the message to the IP address of the downstream node. The SR network control plane updates the locator database to map (i) the GIP address for the UE to (ii) a different IP address of a downstream node upon the SR network control plane determining that the association of the UE has changed to the different IP address.

Abstract: Leaf nodes of a tree structure, also having a root node and intermediate nodes, communicate with endpoints via access networks and store mappings from permanent virtual IP (VIP) addresses for the endpoints to physical IP (PIP) addresses for the endpoints on the access networks. The root node and intermediate nodes store pointers for the endpoints' leaf nodes and associated access networks. When a connection setup request (CSR) for a destination endpoint is received from a corresponding node, the receiving leaf node passes the CSR up through the tree structure to a lowest common ancestor (LCA) node for the receiving leaf node and one or more destination leaf nodes associated with the destination endpoint. The LCA node uses its pointers to pass the CSR down towards the one or more destination leaf nodes, which use the corresponding VIP-to-PIP mappings to forward the CSR to the destination endpoint.
