摘要: A router in a switching network has input interfaces communicatively coupled to other routers and first and second output interfaces communicatively coupled to other routers in the switching network. First and second output interface queues, respectively associated with the first and second output interfaces, store data packets awaiting transmission respectively on the first and second output interfaces. A routing table maps first and second destination addresses to the first output interface as a primary interface and maps the first destination address to the second output interface as an alternate interface. A route controller assigns, using the routing table, data packets having one of the first or second destination address to the primary output interface for transmission, the primary output interface being the first output interface. The controller monitors the first output interface queue and determines whether to activate an alternate route for transmitting data packets having the first destination address over the switching network.

摘要: Provided are a method and device for packet forwarding. The method comprises: interface direction information and a routing table issued by a control plane are received, where a route in the routing table carries a routing direction identifier; when a packet is received from an interface, a forwarding plane determines the interface direction of an incoming interface of the packet according to the interface direction information, and determines a routing direction of the packet according to the routing direction identifier; if the interface direction of the incoming interface matches the routing direction, then the packet is forwarded; and if not, then the packet is discarded.

摘要: Techniques for improved routing based on network traffic are provided. Telemetry data relating to a first network node of a plurality of network nodes in a locator ID separation protocol (LISP) fabric is received. A first portion of the telemetry data that relates to a first destination of a plurality of destinations is identified. Further, a first routing weight associated with a first interface of the first network node is revised based on the first portion of the telemetry data, where the first interface is associated with the first destination. The revised first routing weight is published to a second plurality of network nodes in the LISP fabric, wherein the second plurality of network nodes route packets to the first network node based in part on the revised first routing weight.

摘要: Some embodiments provide a method for processing a packet for a pipeline of a hardware switch. The pipeline, in some embodiments, includes several different stages that match against packet header fields and modify packet header fields. The method receives a packet that includes a set of packet headers. The method then populates, for each packet header in the set of packet headers, (i) a first set of registers with packet header field values of the packet header that are used in the pipeline, and (ii) a second set of registers with packet header field values of the packet header that are not used in the pipeline.

摘要: Embodiments of the present invention disclose a data packet processing method and apparatus, and a device. The method includes: if a first data packet is received, determining a first cache queue that is in the first buffer and that is used to store the first data packet; buffering the first data packet in the second buffer if a state of the first cache queue is an invalid state, where a data amount of the first data packet is less than the capacity of the second buffer, and the state of the first cache queue is set to the invalid state when a current data amount of the first buffer reaches the capacity of the first buffer; and if a data amount of the second buffer reaches the capacity of the second buffer, sending all data packets that are in the second buffer to a control plane device.
