摘要： Systems, methods, and computer-readable media for an intelligent load balancer. In some embodiments, a system can analyze activity data for egress links associated with a network. The system can also receive a service request originating from a remote device. Next, the system can select a server in the network for receiving the service request. Based on the activity data, the system can also select an egress link from the egress links for communicating data associated with the service request from the network to a remote destination location, such as the remote device. The system can then send a signal to the selected server which can include the service request and an indication of the egress link to be used for the data associated with the service request. The system can also later change the selected egress link for the service request if the system subsequently identifies a better egress link.

摘要： Embodiments of the present disclosure relate to methods and systems for on-demand next-hop resolution. Aspects of the embodiments include receiving a triggering event to prompt a request for a path to a network location; requesting a path computation from a second network element based on receiving the triggering event; receiving the path computation from the second network element; and programming an output interface with an indication of the path computation received from the second network element.

摘要： First and second egress nodes are each multi-homed to a customer edge (CE) that participates in virtual routing and forwarding (VRF). First forwarding information is configured on the first egress node. The first information includes VRF labels and defines forwarding of traffic based on the VRF labels and a status of a primary path to the CE. The VRF labels include a per-VRF label for the VRF and a per-CE label for the CE. Second forwarding information is configured on the second egress node. The second forwarding information includes the per-VRF label and the per-CE label, and defines traffic forwarding based on the VRF labels. Upon receiving traffic for the CE that carries the per-VRF label, the first egress node determines the status of the primary path, and forwards the traffic to either the CE over the primary path or to the second egress node, depending on the status.
