Problems solved by technology

[0007] (1) Due to the different business of each section in the Taiwan-wide network, the utilization rate of each section varies from high to low, and the utilization rate of media data files owned by the section also varies from high to low. Suppose it is configured under a high-usage section A The number of transmission terminal xPeers and the number of transmission terminal xPeers configured under a low-utilization section B are the same. At the same time, due to the large number of services under A, the xPeers responsible for transmission under this section and the xPeers responsible for other services (such as transcoding) must be divided. Therefore, the xPeer used for transmission will be affected by other services, and the efficiency of transmission scheduling will also be affected
[0008](2) The data transmission scheduling method starts with a task. If there is no suitable transmission route under the task, the task will wait for a long time and requires management personnel Manually change transfer settings to start transfer

Embodiment 1

[0025] Assume that the entire network of a TV station includes three sections A, B, and C, and five xPeer transmission terminals a, b, c, d, and e. First, configure the channel. The channel refers to the dedicated and directional transmission path between the plates. The elements in the channel configuration mainly include: the source section, the destination section, and several xPeer terminals interconnected within the entire station network. In the channel configuration, it is necessary to determine the transmission direction of the media data file and the expected transmission frequency, so as to configure the number of xPeers performing tasks under the channel on this basis. Assume that a and b are the sending end responsible for transferring media data files of sector A to sector B, c is the receiving end responsible for transferring media data files of sector A to sector B; e is responsible for transferring media data files of sector C to sector A The sending end, c and d a...

Embodiment 2

[0040] This embodiment makes a further improvement to Embodiment 1. On the basis of Example 1, the steps of channel routing and transfer are added, which can improve the media data file transmission by transferring when there is no channel between the sections, or when the channel is temporarily unavailable under the target section. Real-time performance and transmission efficiency.

[0041]Channel routing means that when the source and destination sections cannot directly transmit media data, they can transit through other sections, and the ultimate goal has been reached. This method can be applied to the occasional case of transmission between the two sections, that is, two sections. The infrequent exchange of media data between sectors. It can not only overcome the lack of real-time transmission of media files, but also prevent the administrator from frequently configuring channels, reducing the administrator's workload.

[0042] In this embodiment, it is assumed that the media...

Embodiment 3

[0045] This embodiment makes a further improvement to the second embodiment, that is, how to select the best transfer channel when there are two or more transfer channels.

[0046] First select the channel with the largest number of free connections in the primary transmission channel and the number of free connections in the secondary transmission channel is not 0 as the transit channel for data transmission.

[0047] For example, there are three transfer channels: A1→B1→C1, A1→B2→C1 and A1→B3→C1. Assume that the parameters before data transmission scheduling are as follows:

[0048] (1) There is an idle xPeer server under A1 of A1→B1, and the number of free connections is 5; B1→C1 has an idle xPeer server under B1, and the number of free connections is 10;

[0049] (2) There is an idle xPeer server under A1 of A1→B2, and the number of free connections is 8; under B2 of B2→C1, there is an idle xPeer server, and the number of free connections is 1;

[0050] (3) There is an idle xP...

Abstract

The invention discloses a data transmission scheduling method based on channel configuration, belonging to the technical field of data transmission scheduling. The prior data transmission scheduling method is as follows: taking an assignment as a starting point for transmission scheduling, extracting a source plate and an objective plate in the assignment and confirming a sending terminal and a receiving terminal for transmission through selecting an xPeer terminal under the source plate and an xPeer terminal under the objective plate, then executing the assignment through sending out an instruction by an M-Peer. By the way, the transmission scheduling has lower efficiency. In the method, a channel is used as a starting point for transmission scheduling, firstly, whether the channel exists in a source terminal and an objective terminal or not is queried in a channel list, if no channel exists, transferring is performed by a channel router; and if the channel exists and the channel is usable, then a channel connection is built for transmitting data. The channel has specificity and directivity, and therefore, the method can remarkably improve the efficiency of data transmission scheduling.

Description

Technical field [0001] The invention belongs to the technical field of data transmission scheduling, and specifically relates to a data transmission scheduling method based on channel configuration. Background technique [0002] In the field of radio and television, with the digital transformation of TV stations’ internal business systems and the construction of various systems and networks within the TV stations, a TV station often forms collections and collections, news production and broadcasting, comprehensive production, studio networks, scheduling and broadcasting, and media asset management. , Broadcast and distribution and many other business sectors. Due to the increase in business sectors, the need for interconnection between sectors has emerged. [0003] In the prior art, there is a TV station-wide network solution based on an SOA architecture. This program integrates major business segments into the backbone platform to realize the interconnection and intercommunicati...
