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.

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.
