Access device 1 replicates the data flow, and the source IP address of the data flow after duplication is revised as to the IP address of streaming media server,
The purpose IP address of data flow after duplication is revised as to the IP address of client 1.Access device 1 sends new data stream later
To client 1, the source IP address of the new data stream is the IP address of streaming media server, and purpose IP address is the IP of client 1
Address.
From figure 5 it can be seen that streaming media server no longer sends data flow in client 1, and by access device 1
It directly sends data flow in client 1, the transmission path of data flow does not repeat.
In one example, access device 1 can also be by purpose MAC (the Media Access of the data flow after duplication
Control, medium access control) address is revised as the MAC Address of client 1.
In one example, video management server can also notify client 1, the source IP address of the data flow received
It is the IP address of streaming media server, so that client 1 receives and handles the IP address that source IP address is streaming media server
Data flow, the treatment process of client 1 no longer repeat in detail.
In one example, for application scenarios shown in Fig. 3, it is assumed that currently only client 1 requests headend equipment
Data flow, without the data flow of other client request headend equipments, then video management server notice headend equipment will count
Client 1 is transmitted directly to according to stream.Based on this, headend equipment is sent to client 1 after collecting data flow, by data flow,
The source IP address of the data flow is the IP address of headend equipment, and purpose IP address is the IP address of client 1.Access device 1 exists
After receiving the data flow, data flow directly can be sent to client 1 by the purpose IP address based on the data flow.
Application scenarios 2: can be with as shown in fig. 6, on the basis of application scenarios 1 shown in Fig. 3, in video monitoring system
Including access device 2, the client 2 and client 3 that are connect with access device 2.Assuming that the first request data stream of client 2, client
Request data stream behind end 3, then streaming media server sends data flow to client 2, and client 2 is source client, visitor at this time
Family end 3 is purpose client.Assuming that the first request data stream of client 3, request data stream after client 2, then streaming media server
Data flow is sent to client 3, client 3 is source client at this time, and client 2 is purpose client.
The process that the data flow of headend equipment is requested for client 1, identical as application scenarios 1, details are not described herein, with
Under request the process of data flow of headend equipment to be illustrated 2/ client 3 of client.
As shown in fig. 6, the client 2 or client 3 can be in the client 2 perhaps registration process of client 3
Access device 2 sends the first logon message and first logon message is sent to video management service by access device 2 later
Device.Video management server completes the registration process of client 2 or client 3 after receiving first logon message,
Details are not described herein for the process flow of the registration process, so that client 2 or client 3 can be linked into video monitoring system
In.
Access device 2 is receiving the first registration from the client 2 or client 3 connecting with this access device 2
When message, on the basis of the first logon message is sent to video management server, the first logon message can also be carried out
Detection is listened to, and facility information such as client 2 or the client of the perhaps client 3 of client 2 are parsed from the first logon message
The information such as device identification, IP address of equipment, the device type at end 3.Access device 2 sends the second registration to video management server
Message carries the facility information of client 2 or client 3 and the information of this access device 2 in second logon message, such as
Mark, IP address, device type and the client 2 or client 3 of access device 2 are connected to the interface letter of access device 2
It ceases (such as client 2 is connected to interface 1, and client 3 is connected to interface 2).
Video management server knows client 2 or client 3 (from second after receiving the second logon message
Parsed in the client 2 of logon message or the facility information of client 3) with access device 2 (from connecing for the second logon message
Enter and parsed in the information of equipment 2) connection, and client 2 is connected under the interface 1 of access device 2, and client 3 is connected to
Under the interface 2 of access device 2.
In the embodiment of the present invention, video management server is receiving the first registration from client 2 or client 3
After message, if not receiving the second logon message from the access device 2, video in preset time (such as 3 minutes)
Management server thinks client 2 or client 3 is not to be connected on legal access device that (legal access device is in visitor
In the registration process of family end 2 or client 3, second logon message of this access device can be sent, so that video management service
Device completes the registration process of this access device), and refuse client 2 or client 3 is linked into video monitoring system (due to it
Before have allowed for client 2 perhaps client 3 be linked into video monitoring system therefore make client 2 or visitor in subsequent process
Family end 3 is offline), to guarantee the safety of entire video monitoring system.
Based on the above process, video management server can know that client 2 is connected under the interface 1 of access device 2, and
And know that client 3 is connected under the interface 2 of access device 2.Therefore, video management server can know access device 2 with
At least two clients (i.e. client 2 and client 3) connection, it is assumed that the first request data stream of client 2 is requested after client 3
Data flow, then client 2 is the source client of client 3, and client 3 is purpose client.Later, it is come from if received
The message for request data stream of source client, then video management server sends duplication to access device 2 and redirects plan
Slightly, which redirects strategy for making 2 convection media server of access device be sent to source client (client 2)
Data flow is replicated, and obtains a new data stream, and the new data stream is sent to source client (client 2).
Based on foregoing description, in the embodiment of the present invention, access device 2 is receiving the duplication from video management server
After redirecting strategy, the data flow that the duplication redirects strategy is matched if received, access device 2 is according to the data flow
Destination address send the data flow (data flow being sent to source client, such as client 2), and utilize the duplication weight
Directional strategy is that the purpose client (such as client 3) replicates new data stream, and the new data stream is sent to purpose client
End.
In one example, the match options that duplication redirects strategy can be with are as follows: source IP address is streaming media server
IP address, purpose IP address are the IP address of source client (such as client 2).Action option can be with are as follows: keeps source IP address
Constant, i.e., holding source IP address is the IP address of streaming media server, and purpose IP address is modified as purpose client (such as client
End IP address 3), and new data stream is sent by interface 2 (i.e. client 3 connect on access device 2 interface).
For the collected data flow of headend equipment, after data flow is sent to streaming media server by headend equipment,
After 2/ client 3 of client sends the message for requesting the data flow to video management server, then the data flow is in stream matchmaker
Transmission path between 2/ client 3 of body server and client are as follows:
In the prior art, video management server can notify streaming media server that data flow is sent respectively to client
End 2 and client 3.Based on this, streaming media server can replicate two parts of data flows, and a copy of it data flow is sent to client
End 2, the source IP address of the data flow are the IP address of streaming media server, and purpose IP address is the IP address of client 2；And it is another
A data flow is sent to client 3, and the source IP address of the data flow is the IP address of streaming media server, purpose IP address
For the IP address of client 3.It can thus be seen that streaming media server needs to send two parts of data flows.
In embodiments of the present invention, video management server can notify streaming media server that data flow is sent to client
2 (source clients) are held, but is not longer notified about streaming media server and data flow is sent to client 3.Based on this, streaming media service
Device only replicates a data flow, which is sent to client 2, and the source IP address of the data flow is streaming media server
IP address, purpose IP address are the IP address of client 2.Access device 2 issues the stream compression after receiving the data flow
Client 2.
On the basis of the stream compression is issued client 2 by access device 2, access device 2 can also be from data flow
Source IP address and purpose IP address are parsed, due to the IP address that the source IP address of the data flow is streaming media server, purpose
IP address is the IP address of client 2 (i.e. source client), therefore the data flow can be matched to above-mentioned duplication and redirect plan
Slightly.Based on this, access device 2 replicates the data flow, and keeping the source IP address of the data flow after duplication is streaming media server
IP address (i.e. the source IP address of holding data flow is constant), and the purpose IP address of the data flow after duplication is revised as client
Hold the IP address of 3 (i.e. purpose clients).Later, new data stream is sent to client 3 by access device 2, the new data stream
Source IP address is the IP address of streaming media server, and purpose IP address is the IP address of client 3.
It can thus be seen that streaming media server only sends a data flow, the transmission of data flow is reduced.
In one example, the target MAC (Media Access Control) address of the data flow after duplication can also be revised as client by access device 2
3 MAC Address.In addition, in one example, video management server can also notify client 2 or client 3, connect
The source IP address for the data flow received is the IP address of streaming media server, so that client 2 or client 3 receive and handle source
IP address is the data flow of the IP address of streaming media server, and the treatment process of client 2 or client 3 is no longer gone to live in the household of one's in-laws on getting married in detail
It states.
By application scenarios 1 and application scenarios 2 as can be seen that in the embodiment of the present invention, number can be realized by access device
Distribute according to the duplication of stream, and do not have to streaming media server and duplication distribution is realized to all data flows, to mitigate streaming media service
