When determining the link in network between monitor client and flow congestion occur, network monitoring device will detect network traffic congestion
And the warning information of network congestion is sent, and notify front monitoring front-end (web camera).
In the preferred embodiment of the application, when there is congestion address field in network system is monitored, network monitoring sets
It is standby to send network link information to web camera.Network link information is that network monitoring device passes through in real time to network system
In data traffic be monitored, and obtain after recording to the congestion address field in network system.It can be seen that, in lattice chain
In the information of road, the information of all of congestion address field in network system is contained.
Web camera is after the network link information for receiving network monitoring device transmission, it is possible to obtain network system
In congestion address field information.Afterwards, web camera judges to regard further according to the information of the congestion address field in network system
The network path that frequency request message is passed through whether there is congestion phenomenon.
In the preferred embodiment of the application, web camera can judge video request by following concrete grammar
Whether the flow load of the network path that message is passed through exceedes default load threshold.Specifically, the method at least includes following
The step of：
(1) obtain the network address information of each network equipment on the network path that video request message is passed through.
Web camera is obtained on the network path that video request message is passed through by parsing to video request message
The network address information of all-network equipment (preferably network router).
(2) address field that the network path is passed through is determined according to the network address information of each network equipment.
On network path is obtained after the network address information of all-network equipment, web camera is according to each net
The network address information of network equipment, determines the address field that the network path is passed through.
(3) if the address field of network path process is identical with congestion address field, confirm that the flow of the network path is born
Load has exceeded load threshold.
If the address field that the network path is passed through is identical with congestion address field, illustrate that network path have passed through network system
Congestion address field in system, now then thinks that the flow load of the network path has exceeded load threshold.
(4) if the address field that the network path is passed through is differed with congestion address field, confirm that the flow of network path is born
Carry not less than load threshold.
If the address field that the network path is passed through is differed with congestion address field, illustrate that network path not have passed through
Congestion address field in network system, now then thinks the flow load of the network path not less than load threshold.
Preferred implementation by more than, web camera can rapidly and accurately judge what video request message was passed through
Whether the flow load on network path is super default load threshold.This is the choosing that provides to the Path selection of video flowing afterwards
The foundation selected.
It should be noted that whether the disclosed above flow load for judging networking path is super default load threshold
Method, a kind of preferred implementation that simply the application is proposed, based on the core concept of the application, those skilled in the art may be used also
To take other to judge the whether super method for having default load threshold of the flow load in networking path, this can't affect this Shen
Protection domain please.
In the preferred embodiment of the application, if it is determined that the flow for obtaining the network path of video request message process is born
Carry not less than default load threshold, web camera sends the video flowing to monitor client by the network path.
If the flow load of the network path that video request message is passed through illustrates this not less than default load threshold
There is no the phenomenon of congestion on network path.Now, web camera can be directly by the network path to monitor client
Send video flowing.
S103, if it is determined that the flow load for obtaining the network path of video request message process has exceeded default load
Threshold value, web camera select the paths different from the network path to send video flowing to monitor client, so that video flowing
The flow load of transmitting path is less than load threshold.
If the flow load of the network path that video request message is passed through exceedes default load threshold, the net is illustrated
There is no the phenomenon of congestion on network path.Now, regard if web camera is sent to monitor client by the network path
Frequency flows, it would be possible to there is transmission slowly, or even the phenomenon of error occurs.Meanwhile, monitored picture is watched in monitor client side
The phenomenons such as interim card, Hua Ping just occur, this will have a strong impact on the quality of video monitoring, reduce the viewing experience of user.
Therefore, in embodiments herein, the flow load of the network path passed through in video request message exceedes in advance
If load threshold when, web camera selects paths different from the network path to monitor client transmission video flowing, and
And the flow load in its path for selecting is less than load threshold.So that web camera is sent to monitor client
Video flowing can bypass congestion address field in network system, and then ensure that video flowing can rapidly and accurately to monitoring visitor
Family end is transmitted, and improves the quality of video monitoring and the viewing experience of user.
From the description of above idiographic flow, by the technical scheme using the application, monitor client is being received
During the video request message of transmission, web camera by parsing to video request message, obtains video request report first
The network path that text is passed through；Then the network link information for being provided by network monitoring device judges the flow load of network path
Whether default load threshold is exceeded；If the determination result is YES, web camera selects different from the path of video request message
Path to the monitor client send video flowing, with guarantee video stream path flow be less than default load threshold
Value.Video flowing can be allowed to bypass the congestion address field in network system so as to ensure that, and then ensure that video flowing can be fast
Speed is transmitted to monitor client exactly, improves the quality of video monitoring and the viewing experience of user.
In order to the technological thought of the present invention is expanded on further, in conjunction with specific protocol procedures, the technical side to the application
Case is illustrated.
Present invention mainly solves during nonbursty network congestion, video flowing is unable to connecing for real-time high-efficiency transmission in video surveillance network
The problem of receiving end.The purpose of the present invention is to meet video flowing to network link low time delay, the link requirement of low packet loss ratio.
For the technological thought for more clearly illustrating the application, the first work of the network equipment to being related in the application
With illustrating.
(1) IMP (network monitoring device)
IMP is used for the network topology for managing whole monitoring network, and monitor in real time entirely monitors the data traffic pressure of network,
If there is flow and gathers around in link of the front monitoring front-end (IPC) in a certain network address section in specified network between monitor client
During plug, IMP will detect network traffic congestion and send the warning information of network congestion, and notify IPC (CCTV camera).
(2)IPC
After the order request message for receiving monitor client, parsing first obtains the address pair that request message is passed through to IPC,
Then network link between address above mentioned pair whether congestion is judged again, if congestion, is sending video to the monitor client
During stream, new path is reselected, so that video flowing avoids the network link of congestion.
(3) monitor client
Monitor client carries " record route option ", and in the information of message internal record local network segment, while by Jing
The outgoing interface address information recording for crossing router gets off.
Based on the description of above primary network device, the specific flow process of the application is as follows：
In this flow process, the involved network equipment and interface IP address are as shown in table 1 below
The involved network equipment and interface IP address table in 1. flow processs of table
As shown in Fig. 2 working as in multiple monitor clients (PC1) that address field is 202.15.8.0/24 while at program request
When address field is live for multiple IPC1 of 202.15.7.0/24, video flow sequentially passes through the routers such as A, C, D and is sent to road
By device B, but as the IPC1 ways of program request are excessive, and the monitor terminal of program request is excessive, causes intermediary routing node A, C, D, B
Between link there is interim bursts of traffic, there is the phenomenon of congestion.Now, IMP will send a warning message to IPC1, notify
Congestion is occurred in that between IPC1 routing node A, C, D, B, while all network segment addresses pair for occurring link congestion on the link
(source address and destination address) notifies all IPC1 that location section is 202.15.7.0/24.The ground for now preserving on IPC1
Location network segment address is as shown in table 2 below to gathering：
| Source network segment address | Wildcard bits | Destination network segment address | Destination network segment mask |
| 202.15.7.0 | 255.255.255.0 | 202.15.8.0 | 255.255.255.0 |
| 202.15.7.0 | 255.255.255.0 | 202.15.100.0 | 255.255.255.0 |
| 202.15.7.0 | 255.255.255.0 | 202.15.101.0 | 255.255.255.0 |
| 202.15.7.0 | 255.255.255.0 | 202.15.102.0 | 255.255.255.0 |
2. congestion address network segment of table correspondence table
If matching monitoring request of the address field to (section containing destination address is 202.15.8.0/24), address field
Front monitoring front-end (IPC1) for 202.15.7.0/24 needs routing again when sending video flow, as shown in figure 3, IPC1 according to
Strict source routing option carries out video stream, walks other network links.
Under normal circumstances, in catenet, routing node and remote host that the IP messages that main frame sends are passed through
The routing node passed through to the response message of the main frame is typically different；Monitor client (PC1) is to front monitoring front-end IPC1
When carrying out video request, first locally making requests on message encapsulation, record route option labelling is set, and by local network ground
Location section is write in this request message.The IP address space of 16 bytes is reserved in record route option at most, in monitoring request
It is 202.15.8.0 that the data division of message carries the network address, and mask is the network address segment information of 24.Brief information
It is illustrated in fig. 4 shown below.
When message enters router B, according to the fill rule of record route option, IP messages are added in route B
After route record option, the message format for being forwarded to router F from router B is as shown in Figure 5.
In the same manner, after router F receives the video on-demand request message of monitor client, fill new record route option
Afterwards, monitoring request message and router E being forwarded to from router F, the IP message answers of router E are now forwarded to from router F
Information is as shown in Figure 6.
In the same manner, through the route selection function of IP options, after filling new record route option, monitoring request message is from road
Router A is forwarded to by device E, and the IP message answering informations for now router A being forwarded to from router E are as shown in Figure 7.
After router A receives message as shown in Figure 7, new route record option information is filled, message is sent to
IPC1, the message information that now IPC1 is received are as shown in Figure 8.
IPC1 analytic messages, the route option information, the network address segment information of monitor client in extraction IP options.Send out
Address field in the monitor client network address Duan Nengyu table 2 for now extracting is to matching.IPC1 then judges current video prison
Control request needs carry out routing again, IPC1 with the monitor client carry out all video monitoring service message interactions when
Wait, all carry out source station and route selection.Then video stream packets of the IPC1 subsequently to the hair style of monitor client (PC1) must be in advance
Routing route option information is filled in IP options.The form answer of video stream packet is illustrated in fig. 9 shown below.
After IP messages reach router A, update through route selection option, message is forwarded to into router from router A
E, is now substantially illustrated in fig. 10 shown below from the message format that router A is forwarded to up to router E.
The message that router F, B and destination monitor client (PC1) are received in the same manner is respectively such as the institute of Figure 10,11 and 12
Show.
Through above step, Streaming Media successfully avoids link nodes B, C of flow congestion, it is ensured that video flowing is high in real time
What is imitated is sent to monitor client.
