Abstract: PROBLEM TO BE SOLVED: To speed up appropriate retrieval time in a mail server which requires cost when there are attached files such as image files in addition to a text in a mail and memory capacity for caching all the held mails is secured and whose retrieval processing becomes slow when the mail server stores the mails in a disk and a character string included in the mail text is retrieved in the large-scaled mail server.SOLUTION: A data storage server that can designate a storage destination of data to store the data is installed as a storage region of a mail box server. The mail box server analyzes a construction of the received mail, holds a mail header and a body, which become retrieval objects, in a memory, and holds an attached file which is not the retrieval object of a character string in a disk, in the data storage server.

Abstract: PROBLEM TO BE SOLVED: To provide a retrieval system for efficiently presenting a proper content to a user from evaluation of the user and a state of the content.
SOLUTION: When the user requests content retrieval, a user terminal 10-1 transfers inquiry to user terminals 10-2 to 10-4, retrieves the content, performs processing by use of evaluation information stored in a content individual information storage device 11, and displays it. When the user terminal retrieves and acquires the content, correction of the evaluation information is performed, a latest state of the content is transmitted, and a network 100 is reconfigured by use of a difference of the evaluation information to improve efficiency of the retrieval.

Abstract: PROBLEM TO BE SOLVED: To effectively utilize a mail server resource in an overall system to occurrence of a fault in a certain specific transmission destination mail server or path. SOLUTION: This mail server system includes: a convergence control management part 120 for managing convergence control of an overall mail server system; a convergence statistical information collection part 119 for collecting convergence statistical information of each mail server 120; and a retry server 103 having a retransmission queue 117 having sufficient capacity for performing retry. When detecting a mail server causing a fault from the collected convergence statistical information, the convergence control management part 120 provides a direction of mail transmission restriction addressed to a faulty mail server to each mail server 102. The mail server 102 provided with the direction of the mail transmission restriction addressed to the faulty mail server transfers all the mails addressed thereto to the retry server 103, and transfers the received mails addressed to the faulty mail server to the retry server 103 until a restriction canceling direction is issued from the convergence control management part 120.

Abstract: PROBLEM TO BE SOLVED: To achieve stable service by avoiding congestion of a mail gateway and/or a mail system even when external conditions such as mail profiles and so on are changed, and to facilitate the estimation of the performance of the mail gateway.SOLUTION: A mail gateway monitors plural pieces of information in the internal processing of a program, and when the monitored information exceeds a threshold, the mail gateway determines the degree of influence on congestion for each mail received by the mail gateway, and preferentially regulates the processing of mails having a higher degree of the influence on the congestion. In addition, it visualizes the information on the internal processing of the program, which could not be conventionally monitored from the outside a server, and associates each processing to perform analysis and display.

Abstract: PROBLEM TO BE SOLVED: To solve the problem of an increase in storage capacity and network load of a mail server because of increasing mail traffic in mobile phone carriers.
SOLUTION: A relay device for relaying a mail transfer (SMTP communication) and a mail fetch (IMAP communication) is installed in a carrier facility network. The relay device compresses a mail including a header transferred from a mail transfer server, adds a new header to encapsulate the mail, and transmits the encapsulated mail to an IMAP server as a compressed mail. In response to a mail fetch request from a communication terminal, the relay device decapsulates and restores the compressed mail fetched from the IMAP server, and transmits the restored mail to the communication terminal. The relay device changes parameters, such as the mail size, to prevent inconsistency of IMAP commands from occurring in compressing/restoring the mail.

Abstract: PROBLEM TO BE SOLVED: To limit the impact of congestion state when it is caused by a mail addressed to a mail server to which a queue is not set.SOLUTION: The counting unit 14 of a mail gateway 10 counts the statistical information of specific information for every specific information included in a mail input to a retransmission queue 11b. A new queue creation unit 16 creates a new queue 12 handling a mail having a possibility of causing congestion, based on the counts. Consequently, a normal queue 11 can be prevented from entering the congestion state. When the congestion state is caused in the new queue 12 performing delivery of a mail 40 including specific information, the mail gateway 10 limits input of the mail 40 to the new queue 12 by a mail distribution unit 13, and thereby the impact of congestion state can be limited to the new queue 12.

Abstract translation: 要解决的问题：限制由发送到未设置队列的邮件服务器的邮件引起的拥塞状态的影响。解决方案：邮件网关10的计数单元14对特定信息的统计信息进行计数 对于包括在输入到重传队列11b的邮件中的每个特定信息。 新队列创建单元16基于计数创建处理具有引起拥塞的可能性的邮件的新队列12。 因此，可以防止普通队列11进入拥塞状态。 当在新的队列12中引起包含特定信息的邮件40的传送时的拥塞状态时，邮件网关10通过邮件分配单元13将邮件40的输入限制到新的队列12，从而限制拥塞状态 可以限于新的队列12。
