Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
One of core idea of the embodiment of the present invention is, proposes a kind of message synchronization method, the problem that message synchronization postpones.The embodiment of the present invention is that the user carrying out interacting message by instant messaging gathers and sets up corresponding multicast network and the multicast address configuring described multicast network, in this multicast network, each user's counterpart terminal is as a multicast source node, thus can multicast network be added by sending interaction request and obtain the multicast address of described multicast network, multicast source node sends the packet carrying mutual instant communication information to described multicast address, and in real time from the multicast address of described multicast network synchronously according to the packet of time positive sequence sequence, mutual instant communication information is shown, thus realize the synchronous of instant communication information mutual between each multicast source node in multicast network, in multicast network, packet is without the need to copying forwarding, decrease taking of resource, and decrease due to server orders and the time forwarded, avoid the delay of message synchronization.
Embodiment one
With reference to Fig. 1, show the flow chart of steps of a kind of message synchronization embodiment of the method for the present invention, specifically can comprise the steps:
Step 102, adds multicast network by sending interaction request and obtains the multicast address of described multicast network.
Multicast (Multicast) technology realizes point-to-point configuration and connects between sender and each recipient.In the embodiment of the present invention, adopt multicasting technology to carry out the synchronous of message between instant communication user, therefore first need the user for being carried out interacting message by instant messaging to gather and set up corresponding multicast network, and configure the multicast address of described multicast network.
Wherein, instant messaging is carried out between at least two users, the present embodiment forms user's set by what carried out interacting message by instant messaging more than two users, and the user namely in this user set can obtain the message that in set, each user sends, thus realizes the synchronous interaction of message.Wherein, set identification can be adopted uniquely to represent user's set, and the user adopting this set identification to carry out instant messaging can share all message in this user set.
Owing to usually there is multiple user set in system, in order to reduce the synchronizing relay of user message in each user set, the embodiment of the present invention sets up a multicast network for each user's set, and distribute a multicast address for each multicast network, wherein, the multicast address of each multicast network is unique, and using each user's counterpart terminal in user's set as a multicast source node of described multicast network, therefore, the sender of the message of this multicast network and message recipient are multicast source node, multicast source node does not limit by region, namely multicast source node can extensively distribute in a network Anywhere, thus each user in user's set can carry out interacting message in this multicast network, multicasting technology is adopted to realize the synchronous of message.
After multicast network has been set up, user will with the user in user's cluster carry out instant messaging carry out interaction message time, the corresponding multicast network of this user's cluster can be added, namely the terminal of each user can send interaction request, this interaction request is used for request and adds access customer set, namely add the corresponding multicast network of access customer set, thus the multicast address of multicast network can be obtained by this interaction request and add multicast network.
Step 104, multicast source node sends packet to described multicast address.
User carries out the packing of mutual instant communication information to be generated packet when instant communication information is mutual, and the packing generation method of packet has a lot, and can also be encrypted, the embodiment of the present invention is not construed as limiting this.Then this multicast source node sends this packet to multicast address, by the transmission address of multicast address as packet.
Step 106, multicast source node is the synchronous packet according to time positive sequence sequence from the multicast address of described multicast network in real time, and shows instant communication information mutual in described multicast network according to described each packet.
After message composition data bag is sent to multicast address by multicast source node, the corresponding physical equipment of this multicast address can receive the packet that in this multicast network, a multicast source node sends, due to when in multicast network, multicast source node is many, the same shorter time period interior (as in 1 second) may receive multiple packet, instant communication information order entanglement mutual during in order to prevent synchronization message, when multicast source node reads data from the multicast address of this multicast network in real time, the time positive sequence of the packet read, namely order from front to back sorts to packet the time
Each multicast source node is after receiving this packet, can resolve packet thus obtain synchronous instant communication information and show, during displaying, message can according to this time positive sequence auto-sequencing, while realizing user message in set and be synchronous, also there will not be the problem of message sequence entanglement.
In sum, corresponding multicast network is set up and the multicast address configuring described multicast network for the user being carried out interacting message by instant messaging is gathered, in this multicast network, each user's counterpart terminal is as a multicast source node, thus can multicast network be added by sending interaction request and obtain the multicast address of described multicast network, multicast source node sends the packet carrying mutual instant communication information to described multicast address, and in real time from the multicast address of described multicast network synchronously according to the packet of time positive sequence sequence, mutual instant communication information is shown, thus realize the synchronous of instant communication information mutual between each multicast source node in multicast network, in multicast network, packet is without the need to copying forwarding, decrease taking of resource, and decrease due to server orders and the time forwarded, avoid the delay of message synchronization.
Embodiment two
On the basis of above-described embodiment, the present embodiment discusses the message synchronization method based on multicasting technology further.
With reference to Fig. 2, show the flow chart of steps of a kind of message synchronization method embodiment of the present invention, specifically can comprise the steps:
Step 202, is obtained the set identification of the user's set being carried out interacting message by instant messaging, and distributes a multicast address for described set identification.
Step 204, as a multicast source node, sets up the multicast network based on described multicast address using each user's counterpart terminal in described user's set.
User can adopt the modes such as the application program of client, webpage or mobile terminal to carry out the interacting message of instant messaging, and in the present embodiment, system support can carry out instant messaging more than two users simultaneously.Therefore, for each user's set in system, the set identification of each user set can be obtained, and distribute a multicast address for each set identification, set up the multicast network based on this multicast address.
Wherein system can be that each user gather the multicast address distributing and fix, i.e. the unique corresponding multicast address of set identification, thus the multicast network that the interaction message that this user gathers correspondence is all built by this multicast address is carried out synchronously.Also interim multicast address can be distributed for user gathers, namely user distributes a multicast address when interacting message is carried out in this user set temporarily, and the use in this user set completes interacting message per family, when no longer carrying out interacting message in Preset Time, delete the corresponding relation of this set identification and multicast address, distribute a multicast address again when user carries out interacting message again in this user set temporarily and build interim multicast network.
In this multicast network, each user's counterpart terminal in user's set is as the multicast source node in this multicast network, this multicast source node as sender and the recipient of message in this multicast network, carries out interacting message for the packet sending and receive in this multicast network simultaneously.In user's set, each user adopts user ID uniquely to represent, then this user ID also uniquely can represent a multicast source node, system can store the relation of user ID and multicast address, and a such as employing tables of data stores the user ID of each multicast source node under a multicast address.
Step 206, sends the interaction request of the set identification comprising user's set.
Step 208, receives the multicast address that the described user determined according to described set identification gathers corresponding multicast network.
After setting up multicast network, user carries out instant messaging to add access customer set, interaction message, interaction request can be sent, this interaction request is used for request and adds this user set, namely add this user by this interaction request and gather corresponding multicast network, the set identification of user's set is comprised in this interaction request, thus can determine that user gathers corresponding multicast network by this set identification, and then determine the multicast address of this multicast network, namely this user can obtain the multicast address of this multicast network and add multicast network, then the terminal of user can as of this multicast network multicast source node, the packet that can synchronously read in multicast address carries out data syn-chronization.
Step 210, multicast source node sends packet to described multicast address.
Step 212, multicast source node reads the data of multicast address described in described multicast network in real time, obtains the packet of the time positive sequence sequence according to the time of reception.
User gathers after corresponding multicast network set up, and in this multicast network, each multicast source node can carry out the synchronous with synchronization message of packet.Therefore user sends message, namely multicast source node by this message packing generate Packet Generation on this multicast address.And synchronization message and multicast source node are from read data packet this multicast address.
Wherein, along with increasing of user in user's set, usually the message that in the same shorter time period, (as 1 second) is mutual also can increase, the packet that sends in this shorter time period can be regarded as and sends simultaneously on ordinary meaning, but the message of user interactions has certain order usually, the order entanglement of interaction message probably causes information to be made mistakes, namely cannot the intention of accurate presentation user, the each packet sent in this shorter time period affects Consumer's Experience, even and if still can distinguish the concrete time of reception.
Therefore, multicast source node in real time reading message above-mentioned from multicast address time, read in the time period (above-mentioned short period section) in moment for this reading moment to upper one, multicast address may receive the packet that in multicast network, each multicast source node sends, thus when multicast source node reading data in real-time, the acquisition packet that puts in order of the time positive sequence (from front to back) of the time of reception of packet can be received according to multicast address, realize the real-time synchronization of multicast source node to data in multicast network.
Step 214, described multicast source node carries out resolving the described mutual instant communication information of acquisition to described packet.
Step 216, shows described mutual instant communication information according to the time positive sequence clooating sequence of described packet.
According to after the packet of the time positive sequence sequence of the time of reception in each multicast source synchronisation of nodes multicast address, can resolve packet and obtain mutual instant communication information, then in the display location such as the page, client of instant messaging, mutual instant communication information be shown.
In the embodiment of the present invention, if get final product the message in real-time synchronization multicast network after having new multicast source node (user) to add in multicast network, and the history interaction message before adding to this multicast source node synchronous, also can read from multicast address.
In the embodiment of the present invention, whether multicast network periodically can detect each multicast source node and survive, if multicast source node has exited this multicast network, as user leaves instant communication client, no longer can receive interaction message.In this multicast network, multicast source node can add at any time or exit, and avoids because a certain multicast source node failure causes this user to gather the problem that cannot continue interaction message, and improves the extensibility of this multicast network.
In the present embodiment, the physical equipment such as switch or router can be adopted to receive the packet be sent on this multicast address, and give each multicast source node in this multicast network by the packet delivery in this multicast address.
Such as, build a multicast network with switch, the multicast address of this multicast network and port are set to: 238.1.1.1:10001, as shown in Figure 3.
In this multicast network, each packet (Packet) sender forms the multicast source of multicast, then comprise n multicast source node in this multicast network, assuming that the Packet that each multicast source node sends is the information of the minimum unit that data transmit, be namely indivisible.
In this multicast network during interaction message, each multicast source node sends Packet to multicast address, when each Packet is sent in multicast network, at this moment each Packet sorts according to its transmitting time, multicast source node, when reading the packet in multicast address, can read the Packet sorted according to the positive sequence of time of reception.
When a new multicast source node R joins this multicast network, this multicast source node R directly can read data from multicast address 238.1.1.1:10001, namely reads each Packet by the sequence of transmitting time positive sequence that each multicast source node in this multicast network is sent to multicast address.
Thus, for each multicast source node added in this multicast network, as node 1, node 2 ... node n, namely it become sender and the recipient of message in this multicast network while adding this multicast network, the packet carrying synchronization message can be read from multicast address 238.1.1.1:10001, the quantity of the Packet therefore received by each multicast source node is the summation of the Packet that in this multicast source node self and this multicast network, other each multicast source nodes send, thus achieves message synchronization based on multicasting technology.
In instant messaging not only for the terminal such as application program of client, mobile terminal in the embodiment of the present invention, can also be applied in the instant messaging of webpage, such as be applied to chat system in show field, thus chat message can respond fast to other users, low delay, and for example be applied to the Commentary Systems (as barrage etc.) of collection of drama, thus the comment of user quasi real time can respond to other users.
To sum up, adopt the sequence of multicasting technology realization to message, saved the time of prioritisation of messages, decrease the message delay problem caused due to algorithm sequence, sort in real time in message and there is in synchro system the advantage of low delay.
Secondly, multicast node server can add at any time and exit multicast network, solves Single Point of Faliure problem and parallel-expansion problem.And the multicasting technology that the present embodiment adopts, does not have particular/special requirement to performances such as the CPU of the physical equipment of multicast source node and multicast address, decreases the wasting of resources to scrap build.
