Abstract: Systems and methods are provided to facilitate the distribution of audio signals over wireless networks. In one implementation, an audio system includes a head end having an encoder and a wireless network interface. Audio signals associated with a plurality of audio channels are processed by the encoder to provide an encoded signal in accordance with an audio codec. The encoded signal can be provided to a wireless network by the wireless network interface as a plurality of data packets associated with a network address in accordance with a wireless networking protocol, such as an IEEE 802.11 protocol. One or more remote endpoints can also be provided to receive the data packets from the wireless network, assemble the data packets to obtain the encoded signal, and extract at least one of the audio signals from the encoded signal in accordance with the audio codec. Multicast and unicast implementations are also provided.

Abstract: A method, apparatus and computer program product for providing an encrypted multipoint Virtual Private Network (VPN) service is presented. A first packet of a plurality of packets is received at an ingress provider edge (PE) the plurality of packets destined for a remote server in communication with said egress PE router. A lookup for a destination prefix of a first packet is preformed, and a determination made that a next-hop for the first packet is reachable through a mGRE tunnel. A resolution request is sent to a hub to acquire a routable IP address. The packets sent to the hub are encapsulated, and encrypting until a resolution reply is received and until security associations (SAs) have been exchanged. Then a VPN is established between the ingress and egress PEs and is used for all subsequent packets.

Abstract: A method, apparatus and computer program product for limiting Virtual Private Network (VPNv4) prefixes per VPN in an inter-autonomous system environment are presented. A limit on the number of VPNv4 routes per VPN for a Route Distributor (RD) or a group of RDs associated with a VPN is defined, at an Autonomous System Border Router (ASBR). When the number of received routes at the ASBR exceeds the limit, then a soft notification is sent to a neighboring ASBR and routes exceeding the limit are discarded at the ASBR.
