Wherein, after the present embodiment takes technique scheme, take and represent service node rather than whole service section
Point reports its routing iinformation, and therefore, this kind of method is suitable for service node among Distributed Services network and is susceptible to variation
Network environment, and the method, when representing service node and not producing change, does not produce other Signalling exchanges, therefore, this application phase
For above-described embodiment, there is the technological merit saving Signalling exchange.
Embodiment of the method three:
Distributed network is a dynamic network, and frequently reaching the standard grade inevitably occurs in the service node in network, offline
Phenomenon (shaking, churn).Wherein, the appearance of shake will produce problems, and for example, shake makes to use for terminal
Family provides the node of service to terminate service, and service node terminates providing the information of service must issue in time, otherwise can be to intercommunication
Impact.
End-user listening data can be caused additionally, the service node in described dsn p2p network is reached the standard grade to migrate with offline,
The home service node directly influencing terminal changes.
Wherein, for the service node that certain is reached the standard grade, a part of end-user listening data will move from existing service node
Move this service node, this service node will be actively to dns server sending node address information after reaching the standard grade.Due to service node still
So in dsn network, do not result in the interruption of business, therefore, the impact for intercommunication is little, does not do here and more retouches
State.
Wherein, for certain offline service node, service node leaves network, the user data on service node
To migrate to backup services node.Service node leaves network, produces call loss to ongoing intercommunication first, secondly to rear
There is impact in the domain name mapping of continuous dns, before nodal information entry is aging, the domain name mapping of dns is probably mistake.One
As in the case of, there are two kinds of possible offline modes: graceful pattern and ungraceful pattern.
Wherein, adopting graceful pattern offline if representing service node, before node is offline, representing service node
Actively this node dns dynamic fresh information message can be sent to dns server, instruction dns server deletes < the ip ground of itself
Location, domain name > entry, this kind of mode carry out intercommunication between network and do not have much impact, be not described here in detail.
Wherein, adopt ungraceful pattern offline if representing service node, representing service node will not be actively
Send dns dynamic update message to dns server, but delete this entry after timer expiry, due to surpassing of this timer
When the time be typically both configured to 1 day, if then dns server is before receiving the offline dns dynamic update message of service node,
The ip address of this service node is returned to cscf, then cscf does not know that service node will be offline, continue to service section
Point initiates session establishment request, thus leads to intercommunication failure between network.
For this reason, in the present embodiment, the invention provides a kind of method of network interworking letter, for realizing the appearance of network
Calamity, wherein, Fig. 6 is the schematic diagram of the embodiment of method carrying out mutual communication between heterogeneous networks of the present invention；According to Fig. 6,
The present embodiment comprises the following steps:
S301: a certain service node is chosen for representing service node by Distributed Services network, actively to name server
This is reported to represent the node routing information of service node；
Wherein, if described Distributed Services network is shaken, lead to some to represent service node offline, include again
The following step:
S302: name server obtains a certain predecessor node representing service node, descendant node and secondary node simultaneously
Send dsn network new information；Wherein, above-mentioned network new information carries out sending out based on the dynamic renewal agreement of ietfrfc2063
Send.
Wherein, in one embodiment, described information is deleted for request server and " is represented service node ip address, generation
The information such as table service node domain name "；
S303: name server represents service node according to this acquisition of information and lost efficacy to this；
S304: name server deletes the described information representing service node based on this new information；
S305: name server receives new service node information and as new representative service node, and registers
The information such as the ip address of new representative service node and domain name.
For example, representing the predecessor node of node, descendant node, secondary node, to send dns to dns server dynamic more simultaneously
New information, request dns server deletes " representing service node ip address, represent service node domain name " entry；So can keep away
Exempt to occur continuous nodes on chord ring to lose efficacy and led to the phenomenon that dns server respective entries cannot update.
And, after receiving dynamic update message, dns server is by < the ip of actively offline representative service node
Address, domain name>record, wait new representative node to register<ip address, domain name>record.
By said method, the present invention can avoid because the unexpected generation representing service node changes and leads to distributed
Node failure on network and lead to the corresponding service node information in Distributed Services network cannot update, and, this
Method ensure that the intercommunication session between two networks will not be by affecting that the node in Distributed Services network is shaken.
