    Abstract: Techniques for a head-end node in one or more network autonomous systems to utilize a protocol to instantiate services on tail-end nodes. The head-end node can use a service request mechanism that is enabled by the protocol to request service instantiation on the tail-end node without a network operator having to manually configure the tail-end node, or even having access to the tail-end node. Additionally, the protocol may further provide mechanisms to define handling attributes for traffic of the service (e.g., Service-Level Agreement (SLA) parameters, an underlay transport protocol, etc.), service acknowledgement mechanisms for the head-end node to determine that the service was instantiated on the tail-end node, and so forth. In this way, a head-end node can be used to instantiate a service on a tail-end node without a network operator having to have direct access to the tail-end node to manually configure the tail-end node.

    Abstract: Mechanisms are provided for “direct mode” (in-band) performance loss measurement in computer networks where packet loss is measured directly in the data plane using techniques based on ECMP paths. Counters on each of an ingress node and an egress node are configured by a network controller to count traffic for indicators associated with different equal-cost multi-path (ECMP) paths through a network between ingress and egress nodes. Each indicator is toggled on or off during a measurement interval during which traffic is measured by the traffic counters on the ingress and egress nodes for each ECMP path. The traffic counters (measured in bytes/packets) from the ingress and egress nodes are sent via event driven telemetry to the network controller for performance loss measurement determination.

    Abstract: At a first network device, a plurality of paths through a network from a source network device to a destination network device are determined. A vacant bandwidth is calculated for each of the plurality of paths. A primary path is selected from the plurality of paths based on the vacant bandwidth, and a standby path is selected from the plurality of paths based on the vacant bandwidth.

    Abstract: In one aspect, a method for monitoring a Fast Re-Route (FRR) path between a source node (Node-S) and a destination node (Node-E) in a network, includes generating a discovery-probe at the source node (Node-S) to detect at least one node with an FRR indicator along the FRR path that includes a plurality of next available nodes. The method also includes upon the discovery probe reaching a first node with the FRR indicator, generating a primary probe configured to detect a primary path and a repair probe configured to detect a repair path. The method also includes in response to receiving the primary probe via the primary path and the repair probe via the repair path at the destination node, sending the primary probe and the repair probe back to the source node to monitor the FRR path between the source node and the destination node.

    Abstract: Systems and methods for validating a hardware path capability are provided. The method includes generating, at an ingress node of a network, an operations, administration and maintenance (OAM) probe packet having an OAM bit set associated with validating the hardware path capability, wherein the OAM probe packet comprises a plurality of features; indicating, by each respective intermediate node of a plurality of intermediate nodes in the network along a network path and as instructed by the OAM bit set, whether the respective intermediate node can support the respective feature of the plurality of features; generating, at an egress node associated with the network path, a report regarding whether the plurality of intermediate nodes can support each respective feature of the plurality of features within the OAM probe packet; and determining, based on the report, whether to enable customer traffic implementing the plurality of features along the network path.
