A low-cost, distributed broadband multi-service communication network includes intelligent hybrid communication nodes which communicate with one another. The hybrid communication nodes have multi-media interfaces and processors that allow the node to receive a communication broadcast at one protocol interface, convert the broadcast to other communication protocols, and route it to those different communication protocol interfaces for transmission to other communication media. The smart hybrid communication nodes provides a distributed system that does not rely on a central intelligence, so that the network can be instantly deployed and expanded. In addition, a weatherproof container permits the nodes to be physically mounted adjacent to a communication antenna. This eliminates the need for a cable to connect a transmitter interface to the antenna (which can be several hundred feet away at the top of a tower). Even expensive cable results in substantial power and signal loss.

A method and a wireless telecommunication system of performing network-assisted handover of calls between a serving network and another wireless network that employs communication protocols different from those of the serving network. A message is sent from a mobile station of a user to the serving wireless network, which includes an indication that the mobile station is capable of communicating with the neighboring wireless network. Information relating to the communication characteristics of the neighboring wireless network is also sent from the serving wireless network to the mobile station. Using the information relating to the communication characteristics of the neighboring wireless network, the mobile station receives radio signals from the neighboring wireless network. The quality of the radio signals between the mobile station and the neighboring wireless network is measured. The serving wireless network sends a message to the neighboring wireless network to request a handover of the communication transaction when the quality of the radio signals between the neighboring wireless network and the mobile station meets a predetermined minimum threshold. Then a handover of the communication transaction from the serving wireless network to the neighboring wireless network is executed after the neighboring wireless network has established a communication channel for the mobile station pursuant to the handover request.

Conventional methods of addressing a Distributed Denial of Service attack include taking the target node offline, and routing all traffic to an alternate countermeasure, or “sinkhole” router, therefore requiring substantial lag time to reconfigure the target router into the network. In a network, a system operator monitors a network for undesirable message traffic. Upon a notification of such undesirable message traffic, traffic is rerouted to a filter complex to separate undesirable traffic. The filter complex establishes an alternate route using a second communications protocol, and uses the alternate route to redirect the desirable message traffic to the target node. The use of the second protocol avoids conflict between the redirected desirable traffic and the original, or first, protocol which now performs the reroute. In this manner, the filter complex employs a second alternate communications protocol to reroute and redirect desirable message traffic to the target node while diverting undesirable message traffic, and therefore avoids widespread routing configuration changes by limiting the propagation breadth of the second protocol.
