摘要： An IP tunnel is constructed between routers connected with the INTERNET. A bandwidth of the IP tunnel is assured by setting up a reservation resource protocol (RSVP) on the IP tunnel. Further as a traffic control of the routers and on the IP tunnel, a frequency for sending packets, which are processed by an input processor and an output processor inside of the router, is allotted based on a ratio of the reserved bandwidth in each IP tunnel, then an algorithm for controlling the traffic is simplified. Furthermore each of the routers on the IP tunnel has a function for scheduling a reservation and manages a time period at which the virtual private network (VPN) of a type of the reservation resource protocol (RSVP) will be used, then it is possible to reserve the assurance of the bandwidth on the designated date and time in the future.

摘要： A WAP (Wireless Application Protocol) analyzer located on a transmission line between communication apparatuses using WAP. A WAP packet includes at least one WTP-PDU (Wireless Transaction Protocol—Protocol Data Unit). The WAP analyzer comprising, database (16) for storing state-transition specification data that define a state-transition with a cause-and-effect relationship between WTP-PDUs, states of a WTP layer, primitives between the WTP layer and WSP (Wireless Session Protocol) layer, and states of the WSP layer, based on WAP specification, means (11) for extracting the WTP-PDUs from the WAP packets, and means (13) for estimating the state-transition of the WTP layer and the WSP layer, to the apparatus that received one of the WTP-PDUs and subsequently sent other of the WTP-PDUs, for each pair of a sender and a receiver.
