摘要： An apparatus and methods are disclosed that enable a non-multi-hop wireless terminal (i.e., a wireless terminal that has not been programmed to participate in multi-hop ad-hoc wireless networks) to in fact participate in a multi-hop ad-hoc wireless network, without any changes to the non-multi-hop terminal's software or hardware. In the illustrative embodiment, a wireless terminal T that already belongs to a multi-hop ad-hoc wireless network is assigned to a non-multi-hop wireless terminal W, and a signal is transmitted to terminal W that induces terminal W to use terminal T as a relay for transmitting messages. The assignment of multi-hop-capable terminals in the network to non-multi-hop terminals can be based on a variety of factors, such as signal strengths and the geo-locations of terminals.

摘要： The present invention is a system and method for rapid network failure detection, identification and notification to internet users. It is particular applicable to VoIP applications where such real-time problem identification is particular valuable. It reduces failure detection time by coordinating the sending frequency of RTP and RTCP packets. These incoming packets are monitored and the failure to receive a predetermined number in a specified time window indicates that a network problem has occurred. This problem is then promptly communicated to users of the system.

摘要： A technique is disclosed that attempts to improve the evaluation of a network path's signal quality, as well as the selection of a network path for transmission purposes, without some of the costs and disadvantages of doing so in the prior art. In accordance with the illustrative embodiment, a node with access to the packet network, such as a VoIP telephone endpoint, evaluates the quality of service that is associated with each of multiple network paths. The evaluation process is iterative, in which the number of candidate paths is successively reduced from one iteration of the technique to the next. The multiple paths that remain as candidates in any given iteration are evaluated concurrently and at an evaluation bit rate that i) is less than the full transmission rate of the real-time traffic (VoIP) packets to be sent and ii) varies as a function of the number of candidate paths remaining under consideration.
