The invention discloses Network fusion and control method and system of a CDN and P2P. The invention comprises the following steps of: sending a user name and a password inputted by a login user through a management module of an EMM (Expanded Memory Manager) for authority authentication; generating encrypted business configuration information after adding a user set and the user name to the business configuration information and encrypting by using a business configuration module and sending the encrypted business configuration information to a TS (Terminal Server); carrying out the authorityauthentication on the user by the TS server according to the encrypted business configuration information, and then sending the generated encrypted channel configuration information to a SP server; and deciphering the received encrypted channel configuration information by using the SP server, and then executing operations according to the channel configuration information. Through the technical scheme of the invention, the signal CDN network and a P2P live broadcasting system are lightly fused on the business control to establish a uniform control platform, the configuration, the publishmentand the verification of video sources are intensively and uniformly managed and revealed on the management platform of the CDN, and the user experience effect of the P2P live broadcasting system is improved by using the CDN network, and therefore, the business fusion of the CDN and the P2P is realized.
