    Abstract: Techniques and architecture are described grouping various sources of traffic within a network into grouping fields and assigning each combination of grouping field values an aggregate identification (ID). A first hop edge router may receive a packet and search a mapping table for a corresponding aggregate ID for the combination of grouping field values within the mapping table. If not found, the first hop edge router may assign a corresponding aggregate ID for the combination of grouping field values and store the new aggregate ID for the combination of grouping field values in the mapping table. The first hop edge router may forward the packet on through the network with the aggregate ID embedded in metadata. Routers within the network may measure and aggregate flow metrics of the packet within the network based on the aggregate ID and provide the measurements to the network controller.

    Abstract: In one embodiment, a method includes determining, by a first network component, a sender shaper drop value based on the following: a maximum sequence number; a minimum sequence number; and a sender sequence counter number associated with the first network component. The method also includes determining, by the first network component, a wide area network (WAN) link drop value based on the sender sequence counter number associated with the first network component and a receiver sequence counter number associated with a second network component. The method further includes determining, by the first network component, whether to adjust a sender shaper rate based on the sender shaper drop value and the WAN link drop value.

    Abstract: Techniques described herein can enable proactive congestion notifications based on service level agreement (SLA) thresholds. The disclosed techniques can be performed at a network router device. The router can monitor network traffic performance measurements of network traffic associated with an SLA. The SLA can be associated with an SLA policy, and the SLA policy can comprise performance thresholds such as loss/latency/jitter thresholds, and a congestion notification policy. The congestion notification policy can comprise a portion, e.g., a fraction or percentage, applicable to the performance thresholds to determine congestion notification thresholds. The router can send a congestion notification in response to a network traffic performance measurement exceeding a congestion notification threshold.

    Abstract: In response to receiving one or more packets from an interface, an anchoring border router classifies the traffic flow and either transmits the packets based upon the routing control table as usual, or determines that the packets of the traffic flow are to be forwarded to a forwarding border router. Upon determining that the packets are to be forwarded, the packets are encapsulated with a routing encapsulation key corresponding to a routing path and are forwarded from the anchoring border router to the forwarding border router via a routing encapsulation tunnel. When a forwarding border router receives the redirected packets over the routing encapsulation tunnel, the forwarding border router removes the routing encapsulation key from the packets of the traffic flow and transmits the packets via a routing path corresponding to the routing encapsulation key.

    Abstract translation: 响应于从接口接收到一个或多个分组，锚定边界路由器对业务流进行分类，并根据路由控制表照常发送分组，或者确定业务流的分组将被转发到转发 边界路由器。 在确定要转发数据包时，将使用对应于路由路由的路由封装密钥封装数据包，并通过路由封装隧道从锚定边界路由器转发到转发边界路由器。 当转发边界路由器通过路由封装隧道接收到重定向报文时，转发边界路由器从业务流分组中删除路由封装密钥，并通过与路由封装密钥相对应的路由路径发送报文。

    Abstract: This disclosure describes techniques and mechanisms for intelligently sampling packet flows within a network. The techniques enable the sampling of a limited set of packet flows that show greatest amount of information about the network from the packet flows in order to provide the greatest insight on application performance, network packet, and critical events within the network. Additionally, the techniques provide configurable parameters, such that the techniques are customizable for each user's network.
