Problems solved by technology

[0009] The purpose of the invention is to propose a video grid self-adaptive load balancing scheduling method. This method is based on dynamic regional alliances, dynamically adjusts the scheduling range according to the load situation, makes full use of limited resources, and obtains the intra-regional network with a small scheduling information interaction cost. Load balancing, effectively solve the service load peak problem, maximize throughput, and provide more services

Embodiment Construction

[0027] Content of the present invention is further described as follows in conjunction with accompanying drawing and embodiment:

[0028] A video grid adaptive load balancing scheduling method proposed by the present invention is characterized in that the method generates three tables: the member list of the dynamic area alliance, the virtual organization node list of the home service node and the service provider of the home service node list;

[0029] It specifically includes the following steps, as shown in Figure 4:

[0030] (1) The client first logs in to the grid portal for identity verification, and sends a service request after authorization;

[0031](2) The grid portal automatically directs it to the home service node (usually the streaming media cluster closest to the client as the home service node);

[0032] (3) The home service node inserts the real server IP address of the streaming media cluster in the home service node having the requested content into the vi...

Abstract

This invention relates to one visual network self-adaptive load even transfer method in computer multi-media field, which comprises the following steps: generating dynamic area corporation member list, service point virtual organization point list and belong service point provider list; after customer sends requires, network grid door automatically set its direction to service points and judging whether the real servo satisfies the service quality requires; if yes, ending this transfer; if not, according to dynamic area load value to judge whether the service point satisfies the service needs.

Description

technical field [0001] The invention belongs to the technical field of computer multimedia, in particular to a video grid self-adaptive load balancing dispatcher in the distributed application integration technology. Background technique [0002] Grid technology is a technology emerging in recent years to solve the problem of coordination of distributed resources. It was originally intended for use in distributed computing infrastructure for advanced science and engineering. "Grid problem" is defined as the flexible and safe coordination of resource sharing among dynamic individuals, institutions and resource collections, which is reflected in the concept of virtual organization. In February 2002, at the Global Grid Forum GGF meeting held in Toronto, Canada, the Globus project team and IBM jointly proposed a new grid standard OGSA. OGSA is called the Open Grid Services Architecture (Open Grid Services Architecture). It combines the Globus standard with the commercially-ori...
