Data connecting method, data connecting apparatus, program recording medium

An information drop unit comprising:

• an input means for inputting contents in which at least a plurality of types of priorities are added when the contents are processed;
• a priority corresponding management means making step for dividing said contents into packets of the Internet protocol and making priorities of a plurality of types of said contents correspond to a priority field of packets of said Internet protocol;
• a classification means for classifying said packets to which said priority is made to correspond, into drop classes having at least two or more different drop probabilities based on said priority that is made to correspond;
• and
• a drop means for dropping said packet in accordance with the network load based on said drop classes.

An information drop method comprising:

• an input step for inputting contents in which at least a plurality of types of priorities are added when the contents are processed;
• a correspondence making step for dividing said contents into packets of the Internet protocol and making priorities of a plurality of types of said contents correspond to a priority field of packets of said Internet protocol;
• a first classification step for classifying said packets to which said priority is made to correspond, into first drop classes according to previously assigned rules;
• a second classification step for classifying packets classified as such, into second drop classes having at least two or more different drop probabilities provided in said first drop class, based on said priority made to correspond;
• and
• a drop step for dropping said packets in accordance with the network loads based on said first and second drop classes.

An information drop method characterized by comprising:

• an input step for inputting contents in which at least a plurality of types of priorities are added when the contents are processed;
• a correspondence making step for dividing said contents into packets of the Internet protocols, and for making a plurality of types of priorities of said contents correspond individually to a priority field of packets of said Internet protocol independently;
• a first classification step for classifying said packets, to which said priority correspond is made correspond, into a first drop class based on one of said plurality of types of priorities being made to correspond;
• a second classification step for classifying packets, which has been classified in such a way, into a second drop class having at least two or more different drop probabilities provided in said first drop class based on other priorities than said plurality of types of priorities which have been made to correspond;
• a drop step for dropping said packets according to the network loads based on said first and second drop classes.
