    Abstract: A controller determines a path from a first router in a first segment routing (SR) domain to a destination in a second SR domain, where the path includes a first sub-path in the first SR domain and a second sub-path in the second SR domain. The controller determines first SR instructions, that conform to a first SR protocol, for the first sub-path, and determines second SR instructions, that conform to a second SR protocol, for the second sub-path. The controller sends the first SR instructions to the first router in the first SR domain to enable segment routing of data towards the destination via the first sub-path, and sends the second SR instructions to a second router located at an end of the first sub-path or at a beginning of the second sub-path to enable segment routing of data towards the destination via the second sub-path.

    Abstract: A method, a network device, and a non-transitory computer-readable storage medium are described in relation to an transport congestion control notification service. The transport congestion control notification service may include providing congestion notification by a network device according to a schedule. The congestion notification may be implemented as explicit congestion notification bits included in packets. The schedule may govern the starting and stopping of the congestion notification. The schedule may be generated based on historical congestion states of relevance to the network device. The schedule may be generated by the network device or by an external device and provisioned at the network device.

    Abstract: A controller determines a first path across a first segment routing (SR) domain and a second SR domain to a destination in the second SR domain, where the first SR domain uses a first SR protocol and the second SR domain uses a second SR protocol. The controller determines SR instructions that enable the interworking of the first SR domain and the second SR domain when data is routed across the first path to the destination. The controller sends, prior to the data being routed over the first path, the SR instructions to at least one of a first router in the first SR domain, a second router in the second SR domain, or a third router in the first SR domain to enable the interworking of the first and the second SR domains for segment routing the data across the first path.

    Abstract: A method, a device, and a non-transitory computer-readable storage medium are described in which an predictive discontinuous reception (DRX) bypass service is provided. The bypass service may provide flow control signaling that enables an uplink grant to be transmitted to an end device regardless of the DRX mode. The bypass service may provide for an immediate grant for uplink data and may improve latency. The bypass service may also provide flow control signaling for downlink data that may cause the end device to wake up from a DRX mode and receive downlink data. The bypass service also provides predictive scheduling that allows an external network, such as a multi-access edge computing network to establish a DRX-free downlink connection before completion of data processing. The flow control signaling may include a quality of service flow identifier value that correlates to the bypass service.
