 Examples of these network dependent applications include but are not limited to, email, net based telephony, world wide web and various types of e-commerce. Success of many of these content/service providers as well as commerce sites depend on the quality of service that they provide.
Unfortunately, the connectivity that makes it possible for these servers to provide the content/service, also makes it very easy for hackers to launch denial of service (DOS) attacks against these servers. As a result, techniques for detecting and thwarting undesirable network traffic have become a subject of great interest to the artesian. For example, in co-pending U.S. patent application Ser. No. 09/631,898 entitled “A Distributed Solution For Regulating Network Traffic”, a distributed approach for detecting undesirable traffic is disclosed. In co-pending U.S. patent application Ser. No. 09/685,518, entitled “Progressive and Distributed Regulation of Selected Network Traffic Destined for A Network Node”, a progressive approach to regulating undesirable network traffic is disclosed. While these and other approaches work well and offer various advantages, it is nevertheless further desirable to be able to enable routing devices in a network to be able to independently detect undesirable traffic, and take appropriate action to thwart such traffic as soon as they are detected. Proposals have been made to provide a wireless communication system for passengers in a vehicle such as for aviation use to allow cell phones to be used on an aircraft when in flight. For in-vehicle wireless pico-cells such as those proposed for use on aircraft or in any other suitable moving vehicle (e.g. train, bus, etc.), security concerns are of utmost importance.
An in-vehicle wireless CDMA pico-cell has been proposed for use in an aircraft where, for example, a passenger may activate a personal cell phone that includes not only a wireless wide area network transceiver to communicate for example with ground based networks, but also where the transceiver can operate as a short range wireless local area network transceiver that may communicate for example with an on aircraft CDMA pico-cell. The in-vehicle wireless CDMA pico-cell performs many of the functions of cell towers that are used in CDMA systems on the ground and may also relay calls to an aircraft satellite communication antenna mounted in the aircraft to communicate wireless calls from the CDMA pico-cell to the ground cellular network. A signal is transmitted from the plane's satellite antenna to an orbiting satellite and global positioning technology in the

While these and other approaches work well and offer diverse advantages, it is nevertheless further desirable to be able to enable routing devices in a network to be able to independently detect undesirable dealings, and take appropriate action to thwart such traffic as soon as they are detected.
