Problems solved by technology

[0005] When there are many VCs on demand at the same time, it will cause great performance pressure on MS; MS needs to perform actual address replacement and forwarding functions during data forwarding, which requires a high-performance server to adapt, and the cost is high

Embodiment Construction

[0045] Aiming at the above-mentioned problems in the prior art, the embodiment of the present invention provides a technical solution for data transmission, which is applied to a video monitoring system including a multimedia server MS, an encoder EC, a switch and at least two monitoring clients VC. In this technical solution, the MS allocates a virtual IP address and a MAC address to the VC requesting live streaming, and notifies the EC and the VC of the virtual IP address and virtual MAC address, so that the EC sends the destination IP address and MAC address of the live streaming Set to the virtual IP address and virtual MAC address respectively, and when the VC receives the live stream whose destination IP address and MAC address are respectively the virtual IP address and the virtual MAC address, the live stream is parsed and decoded; wherein, the switch device According to the keep-alive message whose source IP address and MAC address are respectively the above-mentioned ...

Abstract

The invention discloses a method and a system for data transmission. The data transmission method includes that a virtual computer (VC) sends a live registration request on demand to a main storage (MS), the MS distributes a virtual internet protocol (IP) address and a media access control (MAC) address for the VC according to identification information of an electronic computer (EC) carried in the live registration request on demand, and informs the EC and the VC of the virtual IP address and the MAC address; the EC sets the objective IP address and the MAC address of the live stream as the virtual IP address and the MAC address informed by the MS respectively, and sends the live stream to a switch; the switch inquires corresponding MAC entry according to the received virtual MAC address carried in the live stream, and transmits the live stream according to the MAC entry; and when the objective IP address and the MAC address received by the VC are the live stream of the virtual IP address and the MAC address, the VC analyzes and decodes the received live stream. By means of the method and the system for data transmission, performance stress of the MS in the live stream request process is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and system. Background technique [0002] Such as figure 1 As shown in FIG. 1 , it is a schematic diagram of a system architecture of multimedia live on-demand in an existing monitoring system. In this technical solution, the MS (Multimedia Server, multimedia server) performs unicast forwarding and sending to the decoding client for decoding and playing. [0003] Among them, when multiple VCs (Video Clients, monitoring clients) are required to perform live EC (Encoder, encoder) on-demand, the VM (Video Management, video management) server first notifies the EC to send the live stream to the MS in the network. At the same time, the VM sends the IP (Internet Protocol, Internet Protocol) address and MAC (Media Access Control, Media Access Control) address of the VC performing on-demand broadcasting to the MS, and the MS locally generates a...
