Abstract: Systems, methods, and computer-readable media for interconnecting SDWANs through segment routing. A first SDWAN and a second SDWAN of a SDWAN fabric can be identified. A segment routing domain that interconnects the first SDWAN and the second SDWAN can be formed across a WAN underlay of the SDWAN fabric. Data transmission between the first SDWAN and the second SDWAN can be controlled by performing segment routing through the segment routing domain formed between the first SDWAN and the second SDWAN.

Abstract: A process can include determining affinity information indicative of route preferences between branch routers and gateway routers. A prefix can be determined for a subnet of branch routers located at a same branch location. An affinity position of a first gateway router can be determined based on affinity information of the branch routers in the subnet. A mapping can be determined between a local preference Border Gateway Protocol (BGP) community attribute and the affinity position of the first gateway router, wherein a mapped local preference BGP community attribute and the affinity position are indicative of a same routing preference. The mapped local preference BGP community attribute can be attached to routes from the first gateway router into a cloud service provider. Affinity-based route preferences are indicated to the cloud service provider by redistributing the routes from the first gateway router with the mapped local preference BGP community attribute attached.

Abstract: According to certain embodiments, a method by a network device includes receiving a handshake message for a traffic flow from a Software-Defined Wide-Area Network (SDWAN) and determining, from a traffic policy, whether the traffic flow should be symmetrical. In response to determining from the traffic policy that the traffic flow should be symmetrical, the method further includes performing a flow lookup on the traffic flow to determine if the network device originated the traffic flow. In response to determining that the network device did not originate the traffic flow, the method further includes determining a second network device that originated the traffic flow and sending the handshake message for the traffic flow to the second network device in order to maintain symmetry for the traffic flow.

Abstract: Symmetric networking techniques disclosed herein can be applied by gateway routers in cloud networks. The techniques can ensure that both outbound traffic received at a cloud from a branch device and return traffic directed from the cloud back to the branch device are processed by a same gateway router. The gateway router can use network address translation to insert IP addresses from an inside pool and an outside pool assigned to the router.

Abstract: Systems, methods, and computer-readable media for performing threat remediation through a switch fabric of a virtualized network environment. Data traffic passing into a virtualized network environment including a plurality of virtual machines running on a switch fabric is monitored. A network threat introduced through at a least a portion of the data traffic is identified at the switch fabric. One or more remedial measures are performed in the network environment based on the identification of the network threat in the virtualized network environment.

Abstract: This disclosure describes techniques and mechanisms for improving security within SDWAN fabric and utilizing telemetry data from non-enterprise providers to remediate compromised SDWAN site(s) and/or user(s). The techniques may implement an integration of non-enterprise application(s) and API(s) with an enterprise network, thereby enabling the enterprise network to identify compromised endpoint(s), identify user(s), group(s), site(s) that are impacted, and take a corrective action (by the enterprise network and/or the non-enterprise application(s) or API(s)) on the enterprise fabric.

Abstract: Techniques and mechanisms for Fifth Generation (5G) system (5GS) failure detection monitoring of an application or control function in a network for efficient restoration of service are described. The network may be an Internet Protocol (IP) Multimedia Subsystem (IMS) network, and the voice or data service may be an IMS service that utilizes Session Initiation Protocol (SIP) signaling. The application or control function may be a Proxy-Call Session Control Function (P-CSCF) of the IMS network. In some implementations, the procedure may involve a session management function (SMF) programming of a user plane function (UPF) for UPF monitoring of the P-CSCF, using a ping procedure or health check procedure (e.g. for 3GPP Pre-Release 16). In other implementations, the procedure may involve the SMF monitoring of a P-CSCF via a Network Function (NF) Repository Function (NRF) (e.g. for 3GPP Release 16).
