Abstract: A routing device including a memory and a processor. The memory stores instructions. The processor is configured to execute the instructions to receive a signed route origin authorization (ROA), which includes a blockchain hash, and a border gateway protocol (BGP) update message, which includes one or more routes. The processor is further configured to implement a Route Origin Validation (ROV) process using the blockchain hash in the signed ROA to determine whether the one or more routes in the BGP update message are valid; update a routing table to include the one or more routes from the BGP update message when the one or more routes are determined to be valid by the ROV process; and refrain from updating the routing table with the one or more routes from the BGP update message when the one or more routes are determined to be invalid by the ROV process.

Abstract: Techniques are presented to stitch existing virtual private networks (VPNs), such as MPLS based VPNs, with virtual private clouds (VPCs) in public cloud data centers. The stitching architecture can be realized by configuring a virtual routing application (VRA) in the VPCs and configuring virtual routing applications and a virtual routing application controller in the existing VPN. For VPCs in public clouds that do not have a VRA, traffic can be default routed to VPCs with a VRA.

Abstract: A method, an apparatus, and a system are provided for load balancing of a service chain. The method includes: receiving, by a flow classifier, a service chain selection and control policy sent by a policy and charging rules function (PCRF) unit; hashing, by the flow classifier according to a hash quantity, a service flow corresponding to a service chain identifier, to obtain multiple subflows, and adding the service chain identifier and hashing factors to packets of the subflows, where different subflows correspond to different hashing factors; and sending, by the flow classifier, the packets of the subflows after the service chain identifier and the hashing factors are added, to a forwarding device.
