Embodiment Construction

[0022] In a large-scale video surveillance network, there are many surveillance front-end devices. In order to connect these surveillance front-end devices to the video surveillance network, various switches need to be deployed. The first type is the access switch that connects the monitoring front-end equipment to the video surveillance network; the second type is the aggregation switch that aggregates the access switches; the third type is the core switch at the core layer. In this large-scale video surveillance network, the surveillance services that exist at the same time are interlaced. For example, the storage service carried out by the monitoring front-end device to the storage device; the monitoring back-end device initiates a live service for one or more monitoring front-end devices, and so on. In order to ensure the smooth development of various monitoring services, a good network environment is required. For stored streams and live streams, that is, there is no pa...

Abstract

The invention provides a method for adjusting the working speed of convergence switch interfaces. The method is applied to a video management server. The method comprises the steps that A, an SNMP is used for inquiring an MAC address table of a convergence switch, and the MAC addresses learned on the interfaces connected to a switch of the convergence switch are acquired; B, the speeds of all the interfaces of the convergence switch are calculated according to the real-time condition flow and storage flow information sent by all monitoring front end devices in current local records combined with the MAC address information learned on all the interfaces of the convergence switch; C, the working speed of the interfaces with the speed smaller than a preset threshold value is adjusted to be 100 M, and the working speed of the interfaces with the speed larger than or equal to the preset threshold value is adjusted to be 1000 M. According to the scheme, the video management server is used for dynamically adjusting the speeds of the interfaces of the convergence switch according to the code stream needing to be borne in a current network and insisting on the applicable principle, so that the problem that the bandwidth of the interfaces of the convergence switch can be insufficient, and packet loss happens is solved.

Description

technical field [0001] The invention relates to the technical field of video monitoring networks, in particular to a method and a device for adjusting the working rate of a switch interface. Background technique [0002] In the IP video surveillance transmission network, the transmission requirements for network equipment are quite different from the traditional requirements, mainly because the IP video surveillance data packets carried by them have their own characteristics. As we all know, IP video data packets are divided into I frames, P frames, and sometimes B frames. For the network equipment responsible for video data transmission, the situation with the largest traffic load is that the I-frame data of multiple video streams rush in at the same time. At this time, the superimposition of several channels of I-frame data may instantly exceed the output port rate of the network device, which will cause the loss of video data packets, and the actual experience for the us...
