Description
Technical field
The present invention relates to video conference fields more particularly to a kind of multimedia conference system, gatekeeper's server and routing to match
Set method.
Background technique
The current network ISP in China (Internet Service Provider, Internet Service Provider) operator has
China Telecom and China Netcom etc., and the connection bandwidth between network operator is more limited, results in the bottleneck that interconnects, across
Access between net is very slow, and has a large amount of packet losses, thus two-wire, it is multi-thread be that medium and small website solves the preferred plan exchanged visits.
Multi-thread service access way has single IP access, the more IP accesses of Single NIC and the more IP of more network interface cards to access three kinds of access ways, wherein more
Network interface card multi-line is a kind of most common mode.There are many implementations for the routing configuration of the server of more more IP of network interface card, such as
Telecommunications, Netcom's two-wire double netcard router just have following two implementation.
1. static routing mode
1) default route, such as telecommunications are set
The default gateway of # setting system
Ip route replace default via telecommunications gateway dev eth1
2) the detail routing of Netcom is set, all Netcom's network segments have been collected, in addition corresponding static routing.
# is arranged system and routes
Routing table 1via Netcom, ip route add Netcom gateway dev eth2metric 1
Routing table 2via Netcom, ip route add Netcom gateway dev eth2metric 1
……
3) backtracking routing # setting is added by the policybased routing of source forwarding, and priority is higher than 1) 2) routing rule set
After having set, to be also added for every route corresponding " backtracking routing " (data come in from which route, it is final still from
This line is gone out), it not so will appear such problems:
Telecommunication user is accessed by the IP of Netcom less than server, and service can not be accessed in Netcom user by telecommunications IP
Device (data packet can from user reach gatekeeper's server, but gatekeeper's server reply data packet be not from backtracking, for
The intercommunication bottleneck problem of route, data packet are likely to not reach user between operator)
2. policybased routing mode
For convenience, we increase by 2 policybased routing tables, and telecommunications=> 100, Netcom=> 200, add rule again in this way
When, so that it may directly with customized title come Alternative digital
echo"100ctc">>/etc/iproute2/rt_tables
echo"200cnc">>/etc/iproute2/rt_tables
Routing rule is added into table ctc:
Ctc table is arranged in ip route add default via telecommunications gateway dev eth1src telecommunications IP table ctc#
Default gateway
Routing rule is added into table ctc:
Cnc table is arranged in ip route add default via Netcom gateway dev eth2src Netcom IP table cnc#
Default gateway
1) default route (telecommunications) is set
The default gateway of # setting system
Ip route replace default via telecommunications gateway dev eth1
2) policybased routing based on destination address is carried out to Netcom
Ip rule add to Netcom routing table 1table cnc prio 100
# goes to the routing rule in the enabling routing table cnc of Netcom address 1
Ip rule add to Netcom routing table 2table cnc prio 100
……
3) addition backtracking routing
Ip rule add from telecommunications IP table ctc
If # source address is telecommunications IP, the routing rule of routing table ctc is enabled
Ip rule add from Netcom IP table cnc
If # source address is Netcom IP, the routing rule of routing table cnc is enabled
Both the above method is all more complicated, routes (multisegment in particular for the detail for adding non-default gateway network segment
Server program is typically all to be bundled on 0 address for the sake of programming simply, TCP (Transport Control Protocol,
Transmission control protocol) address ip will become the value of determining network segment after link establishment, and UDP (User Datagram
Protocol, User Datagram Protocol) it is no link, source address is always 0, so the rule by source routing of policybased routing
To source address be 0 data packet do not come into force, and RAS (Registration, Admission and Status, registration, allow and
State) signaling transmitted with UDP, so needing to add detail route by purpose routing for RAS signaling), it needs to pay
The routing table provided to operator, and the network topology change of operator is frequent, and system has to and then ceaselessly update road
By table.As soon as being further added by a network segment if necessary, the detail routing of this network segment must be increased simultaneously, workload linearly increases.

Path establishing method provided by the invention is described below with reference to Fig. 2.Fig. 2 shows according to an embodiment of the present invention more
The flow chart of the path establishing method of media conference system.
4 steps are shown in Fig. 2:
Step S210: gatekeeper's server 130 receives the first signaling that terminal is sent.First signaling includes that instruction terminal is wanted
The information of the address of gatekeeper's server 130 of registration.
Specifically, the information of the address of the gatekeeper's server 130 to be registered of instruction terminal can be terminal to be infused
The collateral information of the address of gatekeeper's server 130 of the volume either address of the gatekeeper's server to be registered of instruction terminal.Example
Such as, terminal is used to mark the mark information of the address of different gatekeeper's servers from gatekeeper's server commitment, and believes in transmission first
When enabling, the mark information is carried.Further, no matter terminal and gatekeeper's server 130 are that TCP is linked or UDP is linked, this
One signaling is to be sent to gatekeeper's server 130 by terminal by udp protocol.In a specific embodiment, the first signaling is
One heavyweight registration request signaling (heavyweight Registration Request, heavyweight RRQ), the terminal gatekeeper to be registered
The address of server 130 includes in the nonstandard field of registration request signaling.
Step S220: gatekeeper's server 130 according to received gatekeeper's server 130 address, in address mapping table
Search the gateway address of the address of corresponding gatekeeper's server 130.
Specifically, the first signaling is to be sent to gatekeeper's server 130 by terminal by udp protocol, and since UDP is
A kind of connectionless protocol, and the network address bound when multisegment programming is 0 address, so gatekeeper's server 130 receives terminal
When the first signaling, have no idea by knowing first signaling is forwarded from which gateway address.Therefore, pass through
The information of the address of the included gatekeeper's server 130 to be registered of instruction terminal, is further reflected by address in one signaling
Firing table, to find the gateway address to be passed through when signaling is replied.
Step S230: gatekeeper's server 130 adds the circuit routing that an entry is the terminal for sending the first signaling.Circuit
Routing includes the address of searched gateway address and the terminal for sending the first signaling.
Specifically, calling application programming interface to obtain after gatekeeper's server 130 receives the first signaling that terminal is sent
Take the address of the terminal of the first signaling of transmission.
Step S240: if gatekeeper's server 130, which receives, sends the cancellation signaling that the terminal of the first signaling is sent, end is deleted
The circuit at end routes.
As described above, the present invention has abandoned policybased routing in the prior art and detail routes this two complexity and profession
Allocation plan, when endpoint to register and cancellation by gatekeeper's server 130 automatically increase and delete gatekeeper's server 130 to
The circuit of this terminal routes to get through the circuit that gatekeeper's server 130 arrives terminal.
In conjunction with Fig. 1, in a specific embodiment, the one of address of gatekeeper's server 130 is 211.11.10.21, right
The gateway address (address of route device 120A) for answering network segment is 211.11.10.1, and the address terminal 110A is 211.11.10.19.
It needs to increase a circuit to terminal 110A on gatekeeper's server 130 when then terminal 110A registers online and route, as follows:
route add 211.11.10.19mask 255.255.255.255 211.11.10.1
Gatekeeper's server 130 deletes the routing of this circuit when terminal 110A offline cancellation or gatekeeper's server 130 is refused
The registration of terminal 110A is deleted the circuit after having replied refusal registration request signaling and is routed:
route delete 211.11.10.19mask 255.255.255.255.
The routing of an entry is terminal 110A as can be seen from above circuit needs to know the IP address of terminal 110A and right
Answer the gateway address of network segment.The IP address of opposite end when the IP address of terminal 110A that is, network communication, gatekeeper's server 130 can be with
It is got by application programming interface.Corresponding gateway address can be obtained according to an address mapping table.
The IP address of gateway address network segment corresponding with gatekeeper's server 130 is physically correspondingly, to establish a Zhang Ying
Firing table is such as:
211.11.10.21gw 211.11.10.1
10.17.10.21gw the corresponding gateway address of 10.17.10.1 # gatekeeper's IP address
As long as the IP address for being that is aware of gatekeeper's server 130 that this terminal to be registered is reflected according to address
Firing table gets corresponding gateway address, then establishes corresponding circuit routing.
Fig. 3 shows the timing diagram of terminal according to an embodiment of the present invention and gatekeeper's server Signalling exchange.
First in step S401, server 130 sends a registration request signaling, and the registration request to terminal 110 to the gatekeeper
Signaling carries the address of the corresponding a certain network of gatekeeper's server (GK) 130.Step S402, gatekeeper's server 130, which calls, applies journey
Sequence programming interface obtains the address of terminal 110, according to the address of the corresponding a certain network of gatekeeper's server (GK) 130 in address of cache
Associated gateway address is searched in table, is the circuit road of terminal 110 according to the address of terminal 110 and gateway address adding purpose
By.Step S403, gatekeeper's server 130 reply the response signaling that succeeds in registration to terminal 110.Step S404, terminal 110 is to the gatekeeper
Server 130 sends de-registration request signaling.Step S405, gatekeeper's server 130 is replied to terminal 110 nullifies success response letter
It enables.Step S406, gatekeeper's server 130 are deleted the circuit that purpose is terminal 110 and are routed.Step S403 and step S404 it
Before, terminal 110 can also have other communications to interact with gatekeeper's server 130, for example, the communication in relation to multimedia videoconference
Interaction.

Figure.
In step S301, gatekeeper's server 130 loads the mapping table of gatekeeper's server 130 address and gateway address.In step
Rapid S302, gatekeeper's server 130 listen to the register command for carrying out self terminal.Step S303, gatekeeper's server 130 judge whether to receive
The message of terminal.Step S304 is continued to execute if the message that step S303 judgement receives terminal, gatekeeper's server 130 continues to sentence
Whether the message of disconnected terminal is heavyweight registration request signaling.If step S304 judges that the message of terminal is asked for heavyweight registration
Signaling is sought, then continues to execute step S305, gatekeeper's server 130 is according in the nonstandard field in heavyweight registration request signaling
Corresponding gateway address is searched in address mapping table in the address of gatekeeper's server 130.If finding corresponding gateway address, after
Continuous to execute step S306, gatekeeper's server 130 adds the circuit routing that an entry is the terminal.Step is continued to execute later
S307, gatekeeper's server 130 authenticate terminal, if authenticating successfully, then follow the steps S309, and gatekeeper's server 130 is to end
Accreditation verification (RCF) signaling is replied at end, and will make the terminal that time-out detection be added (after endpoint to register success, at interval of certain
Time threshold needs the transmission of server 130 lightweight registration request signaling to the gatekeeper, with keep-alive terminal and gatekeeper's server 130
Link), and step S302 is continued to execute, gatekeeper's server 130 listens to the message for carrying out self terminal.If in step S302, terminal is super
Crossing certain time threshold value, server 130 does not send message to the gatekeeper, then judges that the terminal is offline, and execute step S310.In step
In rapid S310, gatekeeper's server 130 is deleted the circuit that purpose is the terminal and is routed, and continues back at step S302 later and listens to and comes from
The message of terminal.
If the message that in step s 304, gatekeeper's server 130 judges that terminal is sent is not heavyweight registration request signaling,
Step S312 is then continued to execute, gatekeeper's server 130 judges whether the message that terminal is sent is to nullify signaling.If step S312
In, gatekeeper's server 130 judges the message that terminal is sent to nullify signaling, then gatekeeper's server 130 is nullified true to terminal replies
Determine signaling, and deletes the circuit that purpose is the terminal and route.If in step S312, gatekeeper's server 130 judges what terminal was sent
Message is not to nullify signaling, then can continue to execute step S302 and listen to the message for carrying out self terminal.
If gatekeeper's server 130 does not find corresponding gateway address in address mapping table, then in step S305
Step S309 is executed, at this point, gatekeeper's server 130 passes through default route to terminal replies signaling.
If gatekeeper's server 130 judges that terminal authentication fails in step S307, then step S308 is continued to execute.In step
In rapid S308, gatekeeper's server 130 is to terminal replies registration request failed signaling (RRJ), and deleting purpose is returning for the terminal
Road routing.Later, it continues to execute step S302 and listens to the message for carrying out self terminal.
