Abstract: Systems, methods and computer readable media for mobility integration with fabric-enabled networks are described. Some implementations can include a method comprising terminating, using one or more processors, an access tunnel at an edge switch of a fabric-enabled network, and establishing, using the one or more processors, a mobility tunnel with the edge switch. The method can also include mapping, using the one or more processors, a mobility network to a service identifier associated with the mobility network. The method can further include forwarding, using the one or more processors, traffic for the mobility network from the edge switch to another edge switch across the fabric enabled network, wherein the traffic includes the service identifier.

Abstract: One or more implementations can include methods, systems and computer readable media for multi-threaded multipath processing. In some implementations, the method can include determining that a next hop for a destination includes a first next hop and a second next hop. The method can also include generating a first packet having a first destination address based on a nickname of a remote switch and on an identifier of a first path. The method can further include generating a second packet having a second destination address based on the nickname of the remote switch and on an identifier of a second path.

Abstract: Some implementations provide a capability of limiting or blocking configuration of network services based on network service mode and type advertisements. An example method can include providing a network service having a service mode and a service type, and generating a network service advertisement message including a service identifier, a service mode portion and a service type portion. The method can also include populating the service mode portion with a first value corresponding to a service mode of the network service and populating the service type portion with a second value corresponding to a service type of the network service. The method can further include forwarding the network service advertisement message from a first system to one or more other systems via a network.

Abstract: Implementations generally relate to data transmission in networks. In some implementations, a method includes determining communication paths in a network, where the communication paths connect a plurality of network nodes, and where the network nodes include one or more edge devices and one or more core devices. The method further includes determining if a forwarding information base (FIB) is permitted at at least one network node. The method further includes filtering one or more packets at the at least one network node if the FIB is not permitted. The method further includes enabling traffic flow of one or more packets at the at least one network node if the FIB is permitted.

Abstract: Systems, methods and computer readable media for network loop detection and prevention are described. Some implementations can include a computerized method comprising detecting, at a first switch, a loop condition in a network, and generating, at the first switch, a localize loop message having an instance count and a path list. The method can also include setting, at the first switch, the instance count of the localize loop message to a first value, and transmitting, from the first switch, the localize loop message to a second switch. The method can further include detecting, at the second switch, a loop in the network; and sending, from the second switch, a localize loop response message to the first switch.
