Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] In digital signature technology, the data to be transmitted is encrypted and decrypted by using asymmetric encryption technology, that is, encryption and decryption use one of the public and private key pairs respectively. If the private key in the public-private key pair is used to encrypt the data to be transmitted, then the public key in the public-private key pair is used to decrypt the encrypted data. Through the digital signature technology, the legal ...

Abstract

The invention discloses a digital signature-based point-to-point flow control method, which comprises that: after a P2P client is started, an application program of the P2P client encrypts flow characteristic data of a media flow to be uploaded by a private key in a public and private key pair to form a digital signature message, and sends the digital signature message to gateway equipment, wherein the public and private key pair is generated by digital signature technology; the gateway equipment decrypts the digital signature message through a public key in the public and private key pair, and identifies the identity of the application program of the P2P client to acquire the flow characteristic data; and the gateway equipment configures a flow management strategy according to the flow characteristic data so as to perform flow control of the media flow to be uploaded according to the flow management strategy. The method can control the uplink flow of a P2P node according to individual requirement of the P2P node so as to provide differentiated service for the P2P node.

Description

technical field [0001] The invention relates to network flow control technology, in particular to a digital signature-based point-to-point flow control method and system. Background technique [0002] Point-to-point (peer to peer, hereinafter referred to as: P2P) technology is a peer-to-peer Internet technology. In a P2P network using P2P technology, each node installed with P2P software has an equal status. It is the client, and each node is also providing services for other nodes while enjoying the services provided by other nodes. Therefore, it is not only the consumer of traffic, but also the producer of traffic. [0003] Since P2P technology makes full use of the computing and sharing capabilities of each node, it has great advantages in terms of scalability and construction costs. In recent years, various Internet applications based on P2P technology, such as file sharing and streaming media, have developed rapidly. P2P download traffic has accounted for more than 70%...
