    Abstract: A method used by an egress router is disclosed. The egress router obtains a capacity index of an application server attached to the egress router. The egress router further obtains a load index describing a load measurement between the egress router and the application server during a certain time period. The egress router encodes the capacity index and the load index into a packet. The egress router transmits the packet to one or more routers in an Internet protocol (IP) network.

    Abstract: A method used by an egress router is disclosed. The egress router receives a first packet from an initial ingress router addressed to an anycast address of an application server. The egress router transmits the first packet to the application server. The egress router receives a second packet from the application server. The second packet is addressed to the initial ingress router. The egress router inserts a sticky destination sub type length value (Sticky-Dst-SubTLV) into a destination option header of the second packet. The egress router transmits the second packet with the Sticky-Dst-SubTLV to the ingress router.

    Abstract: A method for performing virtual private cloud (VPC) routing across multiple public cloud environments. In an embodiment, the method creates a first virtual routing agent (VRA) for a first VPC of a first public cloud. The method sends a registration request to a VRA controller, wherein the registration request comprises a data structure that includes communication parameters of the first VRA. The method receives the communication parameters of other VRAs for other VPCs located in other public cloud environments from the VRA controller. The method uses the communication parameters of the other VRAs for overlay routing of data packets from the first VPC of the first public cloud to other VPCs of other public clouds via the other VRAs of the other VPCs.

    Abstract: A Software Defined Wide Area Network (SD-WAN) edge node is disclosed. The SD-WAN edge node includes edge node SD-WAN ports coupled to untrusted underlay networks. The SD-WAN edge node transmits a first Border Gateway Protocol (BGP) update message advertising WAN (Wide Area Network) properties of the edge node SD-WAN ports to a local controller via an encrypted channel over the untrusted underlay network. The SD-WAN edge node receives a second BGP update message from the local controller, the second BGP update message advertising WAN properties of peer node SD-WAN ports of a peer node. The SD-WAN edge node establishes a security association with the peer node over the untrusted underlay networks based on the WAN properties of the edge node SD-WAN ports and the WAN properties of the peer node SD-WAN ports.

    Abstract: Disclosed are a flow classifier, policy and charging rules function unit and controller. The flow classifier receives a service chain selection control policy sent by a policy and charging rules function unit. The service chain selection control policy includes a corresponding relation between an application type and an identifier of a service chain. The service chain is a path formed by a forwarding device and a value-added service device both of which a service flow with the application type needs to pass through. The flow classifier detects the service flow with the application type based on the service chain selection control policy and adds the identifier of the service chain to a message of the service flow. The flow classifier sends the message of the service flow with the added identifier of the service chain to a forwarding device directly connected to the flow classifier.
