Embodiment Construction

[0008] The whole system includes video server group, load balancing server, IP disk array, program production server and client. The video server group, load balancing server, program production server are located in the backbone of the network, connected by Gigabit Ethernet switch, IP disk array Connect to the 100M port of the switch with Gigabit uplink and 100M downlink port, and then connect to the Gigabit backbone switch from the Gigabit uplink port.

[0009] The video server group is composed of multiple computers with gigabit network interfaces, and a database is installed to store the location information of media files on the IP disk array. The server is responsible for providing streaming media file data to users.

[0010] A database and a WEB server are installed on the load balancing server, the program list user authentication information is stored in the database, the program list is displayed to the user in the form of WEB, and the user is managed and authenticated. ...

Abstract

The invention relates to a high-property distribution parallel VOD system, based on embedded IP storage technique. Wherein, it comprises video server, load balance server, IP disc array, program server and client, while the video server, load balance server, and program server are the main parts of network that connected via kilomega Ethernet exchanger; the IP disc array is connected to the hundred-mega port of exchanger, then via kilomega ascending port to connect the main exchanger. The invention has the advantages that the server not directly operates the flow media document on the memory device, and the data is transmitted by udp protocol, to improve the document manage and transmission efficiency on IP disc; and it uses embedded IP disc as storage node, with low cost and low power consumption; the document is distributed on several network discs, therefore, server can parallel transmit document via network, to improve the I/O property.

Description

Technical field [0001] The invention relates to a high-performance distributed parallel VOD system based on embedded IP storage technology, which belongs to the field of network and digital multimedia technology. Background technique [0002] In a traditional client / server environment, no matter what protocol is used, storage devices are directly connected to the server in the form of a bus. Under this structure, any I / O access operation on the storage device must be completed by the intervention of the server CPU. This method of processing has brought a heavy burden to the server and has caused difficult problems faced by many IT organizations' application systems. There are two main points: a higher transmission rate is required between the server and the storage unit, but the direct-connected storage mode uses bus technology to realize the connection between the server and the storage device, and uses the device protocol to communicate, which reduces the data The transfer rate...
