摘要： PROBLEM TO BE SOLVED: To achieve acceleration of packet transfer by attaining load distribution of packet transfer by means of a plurality of communication paths by virtually expanding the communication paths. SOLUTION: In a packet routing control method, a radio terminal MN1 creates and stores an address translation rule T1. When connecting a radio terminal MN3 to a file server 102, address translation is performed according to the created and stored address translation rule T1 and a decapsulated packet P3-1 is transferred to the radio terminal MN3, but a radio terminal MN2 is also notified about the address translation rule T1 stored in the radio terminal MN1. Thus, similarly to the radio terminal MN1, a destination address Dst is translated from a VPN address of the radio terminal MN1 to a local address of the radio terminal MN3 and a packet P3-2 is transferred from the radio terminal MN2 to the radio terminal MN3. Namely, since the translated address is the local address, the packet 3-2 is delivered to the radio terminal MN3. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：通过虚拟地扩展通信路径，通过多个通信路径获得分组传送的负载分布，来实现分组传送的加速。解决方案：在分组路由控制方法中，无线终端MN1创建并存储地址转换规则T1。当将无线电终端MN3连接到文件服务器102时，根据创建和存储的地址转换规则T1执行地址转换，并且将解封装的分组P3-1传送到无线电终端MN3，但是还向无线电终端MN2通知存储在无线终端MN1中的地址转换规则T1。因此，类似于无线终端MN1，将目的地地址Dst从无线终端MN1的VPN地址转换为无线终端MN3的本地地址，并且将分组P3-2从无线终端MN2传送到无线终端 MN3。也就是说，由于转换的地址是本地地址，所以分组3-2被传送到无线终端MN3。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a load distributor capable of improving load distributing characteristics of a server to be connected. SOLUTION: The load distributor includes: a state acquisition means which acquires the state information of a server to which a received packet should be transferred; a reset means which transmits a reset packet to a transmission source which has transmitted the received packet when the state information shows an abnormal state or a state requiring correction in the case that a destination of the received packet is the server; and a local DNS server which transmits a plurality of pieces of address information to a terminal being a request source when a name solution is requested from the terminal. On reception of the reset packet, the terminal selects a new destination to which the packet should be transmitted among the plurality of pieces of address information received from the local DNS server and transmits the packet to the new destination.

摘要： In a mobile communication system, which has a plurality of radio network controllers and a number of radio base stations connected to each of the radio network controllers, for sending and receiving user data between a host network and mobile stations via the radio network controllers and radio base stations, a plurality of transmission paths that pass through one or more radio network controllers are set up between a base station, which sends and receives radio signals to and from a mobile station, and the host network. When data is being sent and received using one transmission path from the host network to a base station through a radio network controller, traffic conditions on this transmission path are monitored. When traffic has increased, the user data is dispersed by being passed through a plurality of transmission paths.
