Abstract: Accelerating network convergence may be provided. Consistent with embodiments of the disclosure, a mapping server may be configured to map an interconnection of various network elements comprising at least the following: a wireless host, at least two access switches, a plurality of distribution switches, a core switch, a mobility controller, and a mapping database. The mapping server may then receive an indication from the mobility controller that the wireless host has roamed from a first access switch to a second access switch. In response to the indication, the mapping server may remap the interconnection of network elements in the mapping database to update network routing information associated with the wireless host.

Abstract: In one embodiment, a device of a software-defined wide area network (SD-WAN) receives, from a cloud-native application, contextual data for the cloud-native application that identifies microservices of the cloud-native application. The device translates the contextual data for the cloud-native application into a network policy for traffic in the SD-WAN associated with the cloud-native application. The device applies the network policy to a traffic flow in the SD-WAN between an endpoint and a particular microservice of the cloud-native application.

Abstract: Systems and methods for network authorization are described herein. An example method can include receiving a user credential from a host device connected to a network, authenticating the user credential, and in response to authenticating the user credential, determining an authorization policy associated with the host device. The method can also include polling a network overlay control plane of the network to obtain a network location information associated with the host device, identifying at least one network device of the network using the network location information, and transmitting the authorization policy to the at least one network device.

Abstract: The methods and devices discussed herein provide service clustering within a TRILL network without relying on an additional service insertion framework. A TRILL network can include one or more flow distribution RBridges for distributing flows to service nodes. Each flow distribution RBridge can have a virtual base identifier and one or more virtual cluster identifiers. An example method can include maintaining service cluster load balancing structures and receiving a packet that is encapsulated with an inner header and an outer header. The method can include determining whether the egress RBridge identifier is a virtual cluster identifier, and if so, selecting a service node from one of the service cluster load balancing structures. The method can include forwarding the packet to the selected service node.

Abstract: The methods and devices discussed herein provide service clustering within a TRILL network without relying on an additional service insertion framework. A TRILL network can include one or more flow distribution RBridges for distributing flows to service nodes. Each flow distribution RBridge can have a virtual base identifier and one or more virtual cluster identifiers. An example method can include maintaining N service cluster load balancing structures and receiving a packet that is encapsulated with an inner header (source/destination addresses) and an outer header (ingress/egress RBridge identifiers). The method can include determining whether the egress RBridge identifier is a virtual cluster identifier, and if so, applying a hash function to a predetermined flow tuple and selecting a service node associated with the hash value from one of the N service cluster load balancing structures. The method can include forwarding the packet to the selected service node.

Abstract: Changes are made to a virtual network for an endpoint based on the authenticated user identity of the endpoint. The system includes a server and a controller associated with a network fabric to which the endpoint is connected. The network fabric includes network elements to carry network traffic for the endpoint. The server authenticates the endpoint associated with a network address and determines a user identity of the endpoint based on the authentication. The server determines a first virtual network associated with the user identity. The controller receives a notification from the server that the network traffic for the endpoint associated with the network address is to be routed over the first virtual network. The controller updates routing information to associate the network address with the first virtual network and sends the updated routing information to the network elements of the network fabric.

Abstract: A method, system, and computer readable medium is disclosed which utilizes the LISP control plane to increase communications and access to enterprise resources in a network with multiple subnetworks, such as a university setting. As a result, the various embodiments of the present invention provide a routing and services dimension to enterprise discovery protocol traffic, such as Apple Bonjour traffic. A LISP instance ID, which is carried in the LISP header, is used to associate one or more end user devices with specific enterprise resources in a particular subnetwork or a service domain, wherein these resources may be accessed by the end user device even if the end user device migrates to another subnetwork. Another embodiment of the invention limits routing services advertisements from enterprise services to a subset of end user devices associated with particular user EIDs by using L2-LISP multicast techniques.
