Abstract: Mobility traffic drop solutions for EVPN-based networking systems that reduce delays related to a device reassociating from one access point to a different access point. For example, a method may include learning information related to a path of a mobile device configured to travel in a physical space along the path; identifying a plurality of access points having coverage areas that provide service to locations along the path and a plurality of networking tunnel endpoints servicing the plurality of access points; assigning the plurality of networking tunnel endpoints to a mobility zone associated with the mobile device; and transmitting data from a source to at least two of the networking tunnel endpoints of the mobility zone.

Abstract: Techniques for aggregating hardware routing resources in a system of devices are provided. In one embodiment, a device in the system of devices can divide routing entries in a software routing table of the system into a plurality of route subsets. The device can further assign each route subset in the plurality of route subsets to one or more devices in the system. The device can then install, for each route subset that is assigned to the device, routing entries in the route subset into a hardware routing table of the device.

Abstract: Methods for efficiently managing a ternary content-addressable memory (TCAM) by minimizing movements of TCAM entries include determining a first node and a second node in the TCAM, determining if there is a free TCAM entry between the first node and the second node, and storing the new entry in the free TCAM entry. Upon determining that a free TCAM entry does not exist between the first node and the second node, further determining a chain of nodes and then determining if there is a free TCAM entry in the chain of nodes. Upon determining that there is a free TCAM entry within the chain of nodes, moving the TCAM entries identified as the nodes in the chain of nodes to generate a free node nearest to the new entry and inserting the new entry in the free node. Moving the TCAM entries identified as the nodes in the chain of nodes preserves the order of the nodes.
