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.

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.
