Abstract: Techniques for using global virtual network instance (VNI) labels in a multi-domain network to route network data with a multi-tenant network overlay are described herein. A routing device provisioned in a network domain of the multi-domain network may register with a service discovery system of the network domain for use of network configuration data to establish routes through the multi-domain network with network nodes. Each network domain of the multi-domain network may include an application programming interface (API) server for processing API requests to make changes to configurations of a network domain. A border gateway protocol (BGP) large community may be utilized to encode global VNI labels, network addresses, local next hop nodes, and/or additional network information and sent to routing devices provisioned in separate network domains. A service chain may be signaled by global VNI labels to route network traffic through various services prior to reaching a destination endpoint.

Abstract: A first network device associated with a network may establish an Internet protocol version 6 Multiprotocol BGP session with a second network device associated with the network. The first network device and second network device are both capable of forwarding both IPv4 and IPv6 packets with only an IPv6 address configured on the interface of both the first network device and second network device. The first network device may exchange Multiprotocol Reachability capability with second network device for corresponding 2-tuple Address Family Identifier/Subsequent Address Family Identifier. The first network device may advertise Internet protocol version 4 network layer reachability information and may advertise Internet protocol version 6 network layer reachability information with IPv6 extended next hop encoding using Internet Assigned Numbering Authority assigned capability code value 5 to second network device.

Abstract: Systems, methods, and computer-readable media for managing compromised sensors in multi-tiered virtualized environments. In some embodiments, a system can receive, from a first capturing agent deployed in a virtualization layer of a first device, data reports generated based on traffic captured by the first capturing agent. The system can also receive, from a second capturing agent deployed in a hardware layer of a second device, data reports generated based on traffic captured by the second capturing agent. Based on the data reports, the system can determine characteristics of the traffic captured by the first capturing agent and the second capturing agent. The system can then compare the characteristics to determine a multi-layer difference in traffic characteristics. Based on the multi-layer difference in traffic characteristics, the system can determine that the first capturing agent or the second capturing agent is in a faulty state.

Abstract: A Proxy Forwarding node configured to advertise Segment Routing (SR) proxy forwarding capability of the Proxy Forwarding node for neighboring nodes of the Proxy Forwarding node using extensions to interior gateway protocol (IGP) for Proxy Forwarding for enabling an ingress node to the SR Traffic Engineering (SR-TE) path to continue to forward the traffic without modifying a segment list of the SR-TE path that includes a node segment identifier (SID) of a failed neighboring node of the Proxy Forwarding node. When the Proxy Forwarding node receives traffic targeting the failed neighboring node, the Proxy Forwarding node performs SR proxy forwarding for the failed neighboring node by forwarding the traffic towards a destination of the traffic in a direction that avoids the failed neighboring node for a period of time after the IGP has converged.

Abstract: Various example embodiments for supporting stateless multicast in communication networks are presented. Various example embodiments for supporting stateless multicast in communication networks may be configured to support stateless multicast in multi-domain packet distribution networks. Various example embodiments for supporting stateless multicast in communication networks may be configured to support stateless multicast in multi-domain packet distribution networks which may be based on Internet Protocol (IP). Various example embodiments for supporting stateless multicast in a multi-domain packet distribution network may be configured to support multicast of packets based on use of internal multicast packets for multicast communication of the multicast packets within sub-domains of the multi-domain packet distribution network and use of external multicast packets for unicast communication of the multicast packets across or between sub-domains of the multi-domain packet distribution network.

Abstract: A method includes, at a node associated with a multiprotocol label switching system (MPLS) network, identifying information associated with an application flow based on one or more unencapsulated packet headers of the application flow or based on an ingress data stream that includes the application flow. The method further includes, in response to identifying the information, and based on stored data that maps application flows with pseudowires, determining a number of pseudowires corresponding to paths through the MPLS network, where the stored data indicates, for a sending device application, a distributed mapping of the application flow via at least one of the number of pseudowires, and communicating data related to the sending device application via at least one of the number of pseudowires.

Abstract: Embodiments of the present disclosure relate to the technical field of communications, and in particular, to a forwarding method, a forwarding system, an electronic device, and a computer-readable storage medium. The forwarding method includes: acquiring a packet to be forwarded, and detecting whether the packet to be forwarded contains a preset indicator, wherein the preset indicator is used for indicating that the packet to be forwarded has a designated forwarding path; when the packet to be forwarded contains the preset indicator, acquiring information of a protocol header following a Bit Indexed Explicit Replication (BIER) header of the packet to be forwarded, wherein the information of the protocol header is at least used for indicating the designated forwarding path; determining a next hop according to the information of the protocol header; and forwarding the packet to be forwarded according to the next hop.
