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: According to some embodiments, a software defined wide area network (SD-WAN) includes a first region and a second region. The first region includes multiple first routing controllers and multiple first SD-WAN edge routers. The second region includes multiple second routing controllers and multiple second SD-WAN edge routers. Each first SD-WAN edge router of the first region is configured to establish Overlay Management Protocol (OMP) peering connections with the plurality of first routing controllers of the first region but to avoid establishing OMP peering connections with the plurality of second routing controllers of the second region. Each second SD-WAN edge router of the second region is configured to establish OMP peering connections with the plurality of second routing controllers of the second region but to avoid establishing OMP peering connections with the plurality of first routing controllers of the first region.

Abstract: The present disclosure is directed to managing industrial internet of things end points and includes one or more processors and one or more computer-readable non-transitory storage media coupled to the one or more processors and comprising instructions that, when executed by the one or more processors, cause one or more switches to perform operations comprising: identifying a first end point using a protocol associated with the first end point, determining a classification for the identified first end point based on one or more attributes of the first end point, identifying one or more related end points having the classification in common with the first end point, segmenting the first end point with the identified one or more related end points, and applying one or more policies to the segmented first end point and the one or more related end points.

Abstract: A network controller can register WAN edge routers and WAN optimizers distributed across a WAN. The controller can receive a request to establish a WAN optimized connection between first and second hosts. The controller can identify a first WAN optimizer to perform first services (e.g., de-duplication, compression, application acceleration, caching, etc.) for first traffic from the first host to the second host and first complementary services for second traffic from the second host to the first host, and a second WAN optimizer for the second traffic and second complementary services for the first traffic. The controller can establish the optimized connection comprising a first path including the first host, WAN optimizer, and router; a second path including the first router and a second router, and a third path including the second router, WAN optimizer, and host. The controller can route the first and second traffic through the optimized connection.

Abstract: Techniques are provided to communicate the serving Radio Access Network (RAN) element information to the packet core network to enable operators to provide differential treatment for fifth generation (5G) subscribers. The techniques presented herein fill these gaps and help drive faster adoption of Dual Connectivity New Radio (DCNR) subscribers by service operator to offer customized policy and quota management to address different business requirements in the 5G Non-Stand Alone (NSA) architecture.

Abstract: A first virtual machine executing on a centralized management node provides a first image file to a first computing entity arranged within a first point of delivery. The first image file includes a first boot configuration file or a first ramdisk file. A second virtual machine provides a second image file to a second computing entity arranged within a second point of delivery different from the first point of delivery. The second image file includes a second boot configuration file or a second ramdisk file. The first virtual machine provides a third image file to the first computing entity. The third image file comprises a first operating system installation file. The second virtual machine provides a fourth image file to the second computing entity. The fourth image file comprises a second operating system installation file.

Abstract: In one example, an indication that a user equipment participating in a Packet Data Network (PDN) session hosted by a Serving Gateway (SGW) and a PDN Gateway (PGW) is transitioning from a first Mobility Management Entity (MME) to a second MME is obtained. An indication that the SGW is co-located with the PGW and an identification of the SGW are obtained. Based on the indication that the SGW is co-located with the PGW and the identification of the SGW, it is determined that the SGW is reachable from the second MME. In response to determining that the SGW is reachable from the second MME, the SGW is selected to host the PDN session after the user equipment transitions from the first MME to the second MME.

Abstract: A solution for selecting an optimal user Plane entity (with Control and User Plane Separation (CUPS)) per UE during seamless roaming. In one embodiment, a method is provide that is performed by a control plane entity in a mobile core network that supports inter public land mobile network (PLMN) roaming among two or more PLMNs. The method includes obtaining a create session request from an entity in a second PLMN to which a user equipment has roamed from a first PLMN; selecting a particular user plane entity among a plurality of user plane entities based on one or more user equipment related parameters; and establishing a session with the particular user plane entity to serve user plane traffic in the mobile core network for the user equipment.
