Flow-media cluster service content scheduling method based on Netfilter architecture

The invention is a Netfilter structure based stream media cluster service content planning method, including: a, user end sends a service request to a cluster; b, a planner receives the request data package and according to whether there is an active record for the request link in its planning table, transmits the data package to the corresponding server or to other user spaces; c, in the user space, according to the content in the data package, find a server storing the needed program in a program database, consider the regional distribution and load conditions of a server to select an object server, and adds the planning record to the planning table; d, the planner builds a TCP connection from user end to the object server to transmit the data package; e, the object server receives the data package, and then builds a TCP response connection from the object server to user end to send the needed program to user end. It utilizes a planner to unitedly manage the service cluster, implementing intelligent planning of user request, and the efficiency of system is high.
