Problems solved by technology

[0030] When using the forward scheduling process, there are the following problems. First, the DNS system and the IPTV system are usually two independent systems, and the DNS cannot know the current status of each node. But the problem that this node cannot provide services
Second, although the IPTV system has node status information, due to the use of judgment from the center to the edge, it not only increases the delay and response speed of each service, but also greatly increases the management burden of the central node, which is easy to cause A single point of failure that cannot provide services globally after the central node crashes

Embodiment Construction

[0072] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0073] The service scheduling method of the present invention is divided into two parts in the process, as shown in Figure 3:

[0074] The first step is the configuration phase:

[0075] Usually, the original global load balancing process of the DNS and IPTV system is used, and the result of the process is saved locally as static information, that is to say, when the user terminal device is powered on and connected to the relevant server, the global load balancing process of the DNS or IPTV system is used. Information such as the IP address of the edge node obtained during the load balancing process is saved as static information on the user terminal device.

[0076] In addition to the dynamic configuration method, a static configuration method can also be used to configure the configuration information of the user terminal when the u...

Abstract

The present invention discloses a service dispatching method of an interactive television system, which comprises a configuration stage and a service stage; the configuration stage comprises the following procedures: storing the result of the global load balancing on the user terminal device as a static information; the static information at least comprises an IP address of a edge node servicing for the user terminal; the service stage comprises: the user terminal sends a service request information to the edge service node address stored in local; if the edge service node can not satisfy the service request, the service request of the user terminal is leaded to a higher level node, and the service is provided by the higher level node to the user; otherwise, a media service server is selected by the edge node and the IP address is returned to the user terminal. The time efficiency and the serviceability of the service are improved after the proposal of the present invention is utilized, the service pressure of the middle node is decreased, and the affection to the entire system by a single node fault is reduced.

Description

technical field [0001] The invention relates to the IPTV field, in particular to a service scheduling method in the IPTV system. Background technique [0002] IPTV, also known as interactive TV, refers to a brand-new TV service method that uses IP technology as a means of transmission. Combining codec technology, streaming media technology, storage technology, and terminal ), TV playback, VOD (Video On Demand) and other brand-new services with interactive features and user-independent nature, to meet users' needs for personalized TV viewing. At the same time, IPTV is also an important business form for telecom operators to increase ARPU (average revenue per user), increase user loyalty, and cope with competition. At present, many operators in the world have chosen IPTV as a new business development direction. [0003] Normally, when building an IPTV system, an IPTV service operator generally adopts a hierarchical and sub-regional mode to build an IPTV service network. Whe...
