摘要:
A video distribution system according to the present invention includes a user terminal, an SIP session controller, and a video distribution server. When the SIP session controller receives a request to establish a session, the SIP session controller establishes a session between the user terminal and the video distribution server, and controls a bandwidth controller to reserve a bandwidth for the distribution of video content in a communication path between the user terminal and the video distribution server. The video distribution server sends a bandwidth changing request for requesting the SIP session controller to change the bandwidth to reserve a bandwidth depending on a fraction of the bandwidth that is needed for distributing video content. In response to the bandwidth changing request, the SIP session controller further secures a bandwidth for the distribution of video content in the communication path between the user terminal and the video distribution server.

A service providing system is connected to a user terminal via a network, acquires a request message described with an upper layer protocol exceeding three layers for requesting desired data and transmitted by the user terminal, and analyzes the content of a body portion of the message. In the case where unwanted information or unusual information is contained in request content, the unwanted information or the unusual information is eliminated by subjecting the request message to a predefined process.

摘要:
The present invention provides a nonflammable water-based cutting fluid composition which affords excellent dispersion property of abrasives, which does not cause problems involving in flammability upon the use for cutting process of a hard and brittle materials, which can be readily washed, and which can achieve sufficient rust preventive property even if it is used in an equipment for oil use. Provided by the present invention is a nonflammable water-based cutting fluid composition containing a polycarboxylic acid-based polymer compound and/or a salt thereof having a weight-average molecular weight of 1,000-200,000, and additionally a carboxylic acid and/or a salt thereof upon needs for a rust preventive property.
