摘要： PROBLEM TO BE SOLVED: To provide a communication switch device which can use a general industrial network (for example, Ethernet(R), etc.) without the necessity of a special function for each node composing the network, moreover can guarantee a real time property of cyclic information. SOLUTION: The device is provided with a buffer which stores cyclic information received from a high rank port in a circuit-use time zone of the other communication switch device, and I/O data received from low rank ports at any time; and a means which reads out the newest information of the I/O data stored in the buffer in an own circuit-use time zone, and transmits it to the high rank port.

摘要： A front-end processor and a routing management method capable of appropriately controlling the loads on respective routing paths. An Allocating section allocates a router on a first network to a routing section, and a routing information transmitting section transmits routing information to the router allocated to the routing section. The router, which is thus supplied with the routing information, accesses a server computer via the routing section, whereby the processing load of the routing section can be appropriately controlled.

摘要： PROBLEM TO BE SOLVED: To attain band widening of communication from a transmitting terminal to a receiving terminal in multi-link including a link in which communication quality is varied. SOLUTION: In a network system that a packet transmitted from the transmitting terminal and arrives at the receiving terminal via a receiving side sorting device from a transmitting side sorting device 1 flows on the multi-link for bundling a plurality of links between the transmitting side sorting device 1 and the receiving side sorting device, the transmitting side sorting device 1 has an interface which receives the packet transmitted from the transmitting terminal, a link monitoring part 112 which monitors communication quality of the link, a distribution processing part 111 which calculates predicted receiving time of the packet to the receiving side sorting device based on the communication quality of the link for each link constituting the multi-link and determines the link with the earliest predicted receiving time as a transmitting destination link and a tunneling processing part 113 which transmits the packet to the transmitting destinatin link.

摘要： PROBLEM TO BE SOLVED: To provide a distributed streaming internet server system.
SOLUTION: A distributed streaming internet server system comprises multi-tier servers and has data caching, file storage and application server features. The system provides a high-reliability, and streaming media. The system is designed so as to be expanded, so that additional capacity can be easily increased as needed. The use of present remaining capacity is optimized by re-distributing user connection as needed, thereby achieving load balancing and fault processing.

摘要： PROBLEM TO BE SOLVED: To transparently change over a server desired by a client by dynamically selecting it without needing a management server or without imposing a processing load for specifying the server on a client terminal when selecting and accessing a plurality of servers. SOLUTION: Servers 3a-3n are composed by installing totally identical IPv6 anycast address and multicast address, and access from a terminal 1 uses the anycast address. When it is determined for a request file from the terminal 1 that the file cannot be provided, the servers 3a-3n transmit the file request content to other servers by using the multicast address, and annunciate the unicast address of the server having first received the feasibility of provision to the terminal 1 as routing information. After receiving the routing information, the terminal 1 transmits a message to the anycast address by attaching an IPv6 expansion header using the received anycast address for routing information.

摘要翻译：要解决的问题：通过在不需要管理服务器的情况下动态地选择客户端所需的服务器，或者在选择和访问多个服务器时不在客户终端上指定服务器时施加处理负载来透明地切换服务器。解决方案：服务器3a-3n由安装完全相同的IPv6任播地址和组播地址组成，终端1的访问使用任播地址。当确定来自终端1的请求文件不能提供文件时，服务器3a-3n通过使用多播地址将文件请求内容发送到其他服务器，并且通知首先接收到的多播地址的服务器的单播地址提供给终端1作为路由信息的可行性。终端1在接收到路由信息后，通过使用接收的路由信息的任播地址附加IPv6扩展报头，向任播地址发送消息。版权所有（C）2007，JPO＆INPIT
