Abstract: Techniques for utilizing a portion of a communication session identifier (e.g., a Session-ID, an SPI, a CID, a DCID, and/or the like) to indicate a target routing device (e.g., a VPN and/or ZTNA termination device) for establishing control plane session(s) and/or data plane session(s) at wire-speed in a networked computing environment. The routing device(s) of a networked computing environment may generate a communication session identifier and send the communication session identifier to the client device, such that subsequent packets send from the client device may be forwarded to the proper routing device indicated by the communication session identifier for establishment of one or more data plane sessions. Additionally, data plane sessions may be established using a Resumed Handshake rather than a full handshake that is typically required, as Session Resumption utilizes the assigned communication session identifier for mapping.

Abstract: Systems, methods, and computer-readable media are provided for securely advertising autoconfigured prefixes in a cloud environment. In some examples, a method can include, receiving, by a first router, an indication of an available network address prefix. In some aspects, the method can also include selecting, by the first router, a first network address prefix that is within the available network address prefix, wherein the first network address prefix provides at least one route to one or more network elements associated with the first router. In some cases, the method may further include sending, to a second router, a message including a stub registration option that indicates the first network address prefix.

Abstract: Proposed herein at techniques for scalable network traffic steering in a multi-tenant network. In one aspect, a method includes receiving, at an ingress of a multi-tenant network, a data packet, the data packet including a Virtual Network Identifier (VNI) identifying a corresponding tenant for the data packet in the multi-tenant network, and determining, at the ingress, a corresponding cluster of routers for processing the data packet based on the VNI, wherein the corresponding cluster of routers is one of a plurality of clusters of routers in the multi-tenant network. The method further includes forwarding the data packet to a router in the corresponding cluster of routers for processing.

Abstract: Techniques for routing Internet Protocol security (IPsec) data packets. An index is assigned to a Security Parameter Index (SPI) header of the IPsec data packet. The index includes information for routing the data packet to a particular Encapsulating Security Payload (ESP) processor. The data packet can be routed using techniques that are analogous to conventional routing protocols such as IPv4 routing protocol. This allows the data packet to be routed using less expensive routing protocols rather than relying solely on more expensive load balancing techniques to route the data packet. This also advantageously allows the data packet to be routed employing routing techniques developed over decades of routing protocol development.

Abstract: Techniques for a hub node, provisioned in a site of a hub and spoke overlay network, to receive, store, and/or forward network routing information associated with a spoke, and send packets directly to spoke(s) that are remote from the hub node. A first hub node may receive a network advertisement including a border gateway protocol (BGP) large community string from a first spoke local to the first hub node. The first hub node may send the BGP large community string to a second hub node remote from the first hub node. The second hub node may decode network routing information from the BGP large community string and store the network routing information locally. The second hub node may send a packet from a second spoke local to the second hub node directly to the first spoke without the data packet being routed via the first hub node.

Abstract: An approach to establish connections between clusters having overlapping IP address ranges. A method includes receiving, at a service discovery server, from a first node in a first cluster, a service discovery request including a unique name, determining, at the service discovery server, that the unique name resolves to a destination IP address of a second node in a second cluster, determining that the destination IP address overlaps with an IP address range associated with the first cluster, in response to determining that the destination IP address overlaps with the IP address range belonging to the first cluster, configuring a gateway to expect a network connection request from the first node that includes an IP address of the gateway, and sending a service discovery response to the first node, the service discovery response including the IP address of the gateway, but not the destination IP address.

Abstract: Systems, methods, and computer-readable storage media are provided to populate databases with routing data for containers to eliminate the need for continuously accessing a global discovery service. An example method includes initiating, from a source container operating on a first machine in a first rack, a communication with a destination container operating on a second machine on a second rack, wherein a local database on the first machine does not know an address of the destination container. The method includes accessing a global discovery service to provide the address of the destination container, populating the local database on the first machine with the address of the destination container and routing a packet from the source container to the destination container according to the address of the destination container.

Abstract: Systems, methods, and computer-readable media for load balancing using segment routing and application monitoring. A method can involve receiving a packet including a request from a source device to an application associated with a virtual address in a network, mapping the request to a set of candidate servers hosting the application associated with the virtual address, and encoding the set of candidate servers as a list of segments in a segment routing header associated with the packet. The method can further involve determining that a first candidate server from the set of candidate servers is a next segment in the list of segments, encoding the first candidate server in a destination address field on a header of the packet, and forwarding the packet to the first candidate server.

Abstract: A method includes, in a constellation of clients including a first client and a second client, receiving, at the first client, a connection request from the second client, retrieving endpoint reachability data associated with the second client and transmitting, to a server, a connection request based on the endpoint reachability data. The first client receives, from the server and based on the connection request, endpoint reachability information associated with the second client and starts a bidirectional connection with the second client. A direct or indirect tunnel is established between the first client and the second client. The tunnel is set up based on a table which maps a first connectivity option associated with the first client to a second connectivity option associated with the second client to determine whether to establish the direct tunnel or the indirect tunnel between the first client and the second client.

Abstract: A computing device running a local enforcement agent is configured to instantiate at least one application container at the computing device, where the at least one application container is part of a containerized application. The computing device is also configured to associate the local enforcement agent with the least one application container so that the local enforcement agent operates as an intra-application communication proxy for the least one application container. The local enforcement agent receives an intra-application Application Programming Interface (API) call that is sent to the at least one application container from a second application container that is part of the containerized application. The local enforcement agent is configured to analyze the intra-application API call for compliance with one or more security policies associated with the at least one container.
