Embodiment
As shown in Figure 1, the present invention proposes a kind of safe and reliable message delivery system based on mobile network, this message delivery system consists of presentation layer, operation layer and data Layer, and wherein presentation layer consists of client message receiving subsystem, client message receipt subsystem, client message retransmission subpacket system, client message display subsystem; Operation layer consists of server end Message Processing subsystem, server end message retransmission subsystem, server end message push subsystem; Data Layer main usage data storehouse and zookeeper storage presentation layer and the required data of operation layer.This message delivery system is used three machines to build message server cluster and zookeeper cluster: message server cluster is intended to reduce by load balancing the pressure that single server bears, providing more efficiently, more stable service; Zookeeper cluster is mainly to carry out data synchronously and data sharing for each message server.
Presentation layer mainly refers to mobile client, and the interface for user provides interactive operation, comprises the functions such as message receipt, message retransmission and message demonstration.
Operation layer mainly consists of openfire server cluster, for receiving, process, forward and retransmit client message, give client message receipt and to client push message etc.In addition, also comprise data access interface, for accessing boat trip database and zookeeper data storage in length and breadth.
Data Layer is for storing the boat trip related data of application system in length and breadth, and its Air China trip is the main storing subscriber information of database and deferred information etc. in length and breadth, and zookeeper cluster is mainly stored the shared data of openfire cluster.
Client message subsystem, for judging whether the message receiving exists; And display message queue is safeguarded;
Client message receipt subsystem, for constructing the concurrent client message receipt that send.When client successfully receives online message or deferred information, to service end, send the receipt of " successfully receiving online message " or " successfully receiving deferred information ", notification server end client successfully receives message, need not resend this message.
Client message retransmission subpacket system, for resending the unsuccessful message of sending to server.Queue being formed by client transmitted message of client message retransmission subpacket system maintenance, when receiving the receipt of service end success receipt message, from queue, delete corresponding message, if do not receive receipt, when timer period travels through queue, retransmit this message, with this, improve the reliability that user end to server end sends message.
Client message display subsystem, for giving different demonstrations according to type of message to message.For difference common message, message receipt and PUSH message, client message display subsystem ejects the aspects such as mode, message font color and has carried out different processing from message.
Server end Message Processing subsystem, for receiving, forwarding client message and give receipt to client message.After server end receipt message, according to the different conditions of message recipient, carry out different message policies, as direct transmission, save as deferred information, abandon message etc., and send corresponding receipt to sender of the message.
Server end message retransmission subsystem, for resending the unsuccessful message of sending to client.Server end is safeguarded a queue being comprised of server end transmitted message, when receiving receipt, from queue, delete corresponding message, if do not receive receipt, when traveling through queue, retransmits timer period this message, and with this, improve server end and to client, send the reliability of message.Server end is taked the retransmission policy of different stage according to the significance level of message, frequency and the number of times of more important message retransmission are higher.Multi-level retransmission policy be more convenient for customization, more flexible.
Server end message push subsystem, for forward other application servers by server end the message to client push, and obtain the message receipt that client is sent, thereby determine and take which kind of message compensation policy according to message receipt.
Server end Message Processing subsystem, server end message push subsystem, server end message retransmission subsystem cooperate jointly, have guaranteed the high reliability of message push on the basis that completes message push function.
As shown in Figure 2, the safe and reliable message delivery system based on mobile network of the present invention, its message transmitting procedure is divided into 4 stages: (1) sender of the message sends a message to server end; (2) server sends to message recipient by message; (3) message recipient sends to server by receipt; (4) server sends to sender of the message by receipt.Wherein, message receipt can be divided into two large classes according to the state of message recipient: client receipt and server end receipt.When message recipient is online, it receives message and is responsible for structure message receipt later, and sends to server end to be transmitted to sender of the message by server end in this receipt, and this programme is constructed this type of message receipt by client is called client message receipt.When message recipient is non-presence, server end is responsible for constructing message receipt, and this message receipt is sent to sender of the message, and this programme is constructed this type of receipt by server end is called server receipt.As can be seen from Figure 2, to be to construct the main body of receipt different for client receipt and the main distinction of server end receipt.
Fig. 3 is the design sketch of message and message receipt.Message receipt is realized principle:
(1) when message recipient is online, server directly sends to message recipient by message, and by message recipient structure message receipt " the successful receipt message of message recipient ", server is responsible for this message receipt to send to sender of the message;
(2) when message recipient off-line, server is deferred information by message stores, by server constructs message receipt " message has saved as deferred information ", and this message receipt is sent to sender of the message;
(3), when user logins, server extracts from database the deferred information that belongs to this user send to user.User constructs message receipt " message recipient successfully receives deferred information " after receiving deferred information, by server, is responsible for this receipt to be transmitted to sender of the message.
(4) when message recipient does not exist or be anonymous, server constructs message receipt " message recipient does not exist or is anonymous ", and this message receipt is sent to sender of the message;
(5) when message recipient arranges authority disable message sender to its transmission message, server constructs message receipt " because shielding action cannot send to recipient by message ", and this receipt is sent to sender of the message.
Except the 5 class receipts of showing in figure, also have receipts such as " message resend " and " message retransmission number of times has reached the upper limit, abandons retransmitting and being stored as deferred information ", in view of length restriction, at this, will not enumerate.
Fig. 4 is the schematic diagram that openfire cluster and zookeeper cluster carry out data interaction.For supporting message retransmission function, each openfire server need to be shared same message queue, after Openfire receipt message, added to shared queue, receive message receipt Shi Xucong shared queue and delete corresponding message, the present invention uses zookeeper cluster to realize the sharing and synchronization of message queue.Zookeeper is by electing leader and follower, and the correct prerequisite of carrying out of its algorithm is to have machine over half normally to work, therefore should adopt odd number platform machine.Fig. 4 is openfire cluster and the mutual schematic diagram of zookeeper cluster, every machine is disposed an Openfire server and a zookeeper server, between each Openfire, carry out load balance, between each zookeeper, carry out data synchronous, openfire is preferentially from local zookeeper access data.In each machine, only have a machine as master server, all the other are as dependent server, and master server is responsible for the repeating transmission of message.
Fig. 5 is message retransmission mechanism flow chart of the present invention.For realizing message retransmission, need to safeguard a message queue, when openfire receives message, message is added to queue, when receiving message receipt, Openfire deletes corresponding message from queue.Message in queue comprises message body, data such as sending times, last transmitting time, by timer period property, carries out repeating transmission task.When carrying out the queue of timer task traversal, if certain message apart from last time transmitting time surpass threshold value and just retransmit this message, and revise the last transmitting time of message and transmission times, when certain message transmission times reaches the upper of setting, just saved as deferred information in limited time, treat to receive again this message after user logins.Message retransmission mechanism has improved the probability that message is sent to, and has improved communication quality.
Fig. 6 is mobile client message sink flow chart.Client message comprises the steps:
Step 1, client, after message, is compared with the message in client message queue, checks the message that whether has identical id in message queue, if existed, abandons this message.
Step 2, client is saved in the id of the message having shown in message queue, before user's display message, first checking whether this queue has existed this message, if existed, can not repeat to be shown to user, with this, avoid repeating to be shown to user because retransmitting message mechanism receives duplicate message.
Step 3, the type of the message that judgement receives.If what receive is message receipt, in sending message queue, delete the message corresponding with message receipt; If PUSH message, shows PUSH message in client; If common message, display message content in chat interface.
Step 4, corresponding receipt can be constructed and send to client during to PUSH message or common message, to server end, by server, is responsible for message receipt to send to sender of the message.
