Abstract: Solutions are disclosed that enable capacity-aware local repair of tunnels in packet switched wide area networks (WANs). Traffic engineering agents on the routers are programmed to create the tunnels and include sets of primary and alternate tunnels sharing the same source and destination. A tunnel source router is provided a traffic split for allocating incoming traffic to its primary and alternate tunnels for when the primary tunnel is operating at or near full capacity operation, and another traffic split that shifts at least some traffic from the primary tunnel to the alternate tunnel, when the primary tunnel's capacity drops below a threshold. A tunnel may lose capacity for commonly-occurring reasons, such as a disturbance to cabling and faults in optical transceivers. Traffic engineering agents along the tunnel report capacity to the tunnel source router, permitting the network to respond to capacity changes more rapidly than waiting for network tunnel reconfiguration.

Abstract: A system for establishing network reliability for a computer network includes a plurality of initiating nodes to transmit a plurality of packets across the network and a plurality of receiving nodes to receive the plurality of packets via the network. A portion of the plurality of packets transmitted from the initiating nodes are appended with identifiers that correspond to characteristics of entities using the network. The plurality of receiving nodes transmit acknowledgement receipts associated with packets appended with the identifiers to a network monitoring system that monitors quality of service associated with the characteristics.

Abstract: Virtual connections are established between remotely connected servers in a network. The virtual connections include (1) a terrestrial path, as well as (2) a satellite path, for routing the flow of packets through the network. Keys are used for controlling the selective routing of packets through the virtual connections with either the terrestrial path and/or the satellite path. Some tenants in the network are provided virtual connections for enabling their use of the satellite paths and corresponding satellite components. Other tenants are only provided access to terrestrial connections and are restricted from utilizing the referenced satellite components.

Abstract: Solutions are disclosed that enable differentiated admission control for singular flows with bifurcated priorities in a wide area network (WAN). Examples include receiving a bandwidth request for each of a plurality of data flows, each request indicating a primary bandwidth request portion and a deferrable bandwidth request portion; aggregating the bandwidth requests for the plurality of data flows into an aggregate bandwidth request, the aggregate bandwidth request indicating a primary aggregate bandwidth request portion and a deferrable aggregate bandwidth request portion; determining, based on at least the aggregate bandwidth request, a granted primary aggregate bandwidth and a granted deferrable aggregate bandwidth; and based on at least the granted primary aggregate bandwidth and the granted deferrable aggregate bandwidth, allocating, for each bandwidth request for the plurality of data flows, a granted primary bandwidth and a granted deferrable bandwidth.

Abstract: Embodiments are directed to a distributed computing system comprising a plurality of compute nodes for providing resources to users and a hierarchy of two or more layers of controllers coupling the compute nodes to a user interface via a control plane, wherein at least one compute node receives a local application program interface (API) call from an application running on the at least one compute node, the local API call causing the at least one compute node to configure a local resource without requiring commands from the control plane.
