Abstract: Systems, methods, and computer-readable media for communicating policy changes in a Locator/ID Separation Protocol (LISP) based network deployment include receiving, at a first routing device, a first notification from a map server, the first notification indicating a change in a policy for LISP based communication between at least a first endpoint device and at least a second endpoint device, the first endpoint device being connected to a network fabric through the first routing device and the second endpoint device being connected to the network fabric through a second routing device. The first routing device forwards a second notification to the second routing device if one or more entries of a first map cache implemented by the first routing device are affected by the policy change, the second notification indicating a set of one or more endpoints connected to the second routing device that are affected by the policy change.

Abstract: Client address based forwarding of dynamic host configuration protocol response packets may be provided. First, a first relay agent on a first network device may receive a first discovery message associated with a first client device. The first discovery message may include a first discovery message identifier field comprising a first identifier corresponding to the first client device. The first client device may be associated with a subnet. Then the first relay agent may register, with a map server, the first identifier with an address of the first network device and add a gateway address corresponding to the first relay agent to the first discovery message. Next, the first relay agent may encapsulate the first discovery message and forward the encapsulated first discovery message over a network to a border device.

Abstract: In one embodiment, a method for the prioritized transmission of messages includes monitoring a network link of a mobile device to determine performance characteristics of the network link, establishing a network association between the mobile device and a routing network node, receiving a connection request from an application that is directed to a connection between the mobile device and a destination server, determining a relative priority of the connection, mapping the connection to a stream of the network association that is associated with the relative priority of the connection and identifies the destination server, and transmitting messages for the stream to the routing network node interlaced with messages of other streams of the network association based on the performance characteristics of the network link and the relative priority associated with the stream in comparison to relative priorities associated with the other streams of the network association.

Abstract: Group based multicasts may be provided. First, a request may be received. The request may comprise a receiver tag, a request source identifier, and a request multicast group identifier. Next, a source tag corresponding to the request source identifier may be obtained and then it may be determined that a group corresponding to the receiver tag is allowed to access content from a source corresponding to the obtained source tag. In response to determining that the group corresponding to the receiver tag is allowed to access content from the source corresponding to the obtained source tag, content may be received from the source at a multicast group corresponding to the request multicast group identifier. The content may then be forwarded to a receiver corresponding to the request.
