    • 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
    • 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

    • PROBLEM TO BE SOLVED: To provide a method and an apparatus for hiding network topology in a mobile wireless network. SOLUTION: When data is transmitted and received between a management server in a first mobile network, constituting a first management domain and having a plurality of management servers, and a second network constituting a second management domain, the method for hiding the network topology in the above first mobile network includes steps of: transmitting data to the management server in the second network, via a gateway server replacing a real host name of the management server to a random host name of the management server; receiving the data from the management server in the second network via the gateway server; and managing by the gateway server a mapping table representing the correspondence between the above real host name in the management server and the random host name of the management server.
