When failure, the unremitting operation of intermediary's flow rules；Pass through the fault-Tolerant Scheduling Algorithm of component so that single-point is occurring in ESB system
Before and after failure, load can also be maintained within a certain range, to ensure the robustness of system.
In one embodiment, data management platform (also referred to as ESB) also includes following function, services access way: RPC
Remote procedure call (towards method), first end are established network with server and connect, http communication: http communication is based on application
Layer http protocol, application server complete the process of request and 4-Way Handshake by HTTP three-way handshake to disconnect.
Socket communication: Socket communication is the encapsulation based on ICP/IP protocol, communication process in four steps: server is monitored, the
One end request, connection confirmation, data transmission.When encountering network flash, the problems such as connection time-out, server exception: 1. links are deposited
Biopsy is surveyed: first end sends heartbeat detection information to second end, and second end judges link alive state by detecting heartbeat.2. disconnected
Open reconnect test.It is with expansible, unrelated with programming language using simple, unrelated with platform.
The processing request of ESB second end: comprising 1. synchronous obstruction mode (BIO), 2. synchronous non-blocking fashion (NIO), 3. is different
It walks non-blocking fashion (AIO).
Data transmission uses agreement
Http protocol, usual agreement contract include two parts: message header and message body.
Data Serialization and unserializing: text class uses XML/JSON, and binary system uses PB/Thrift.
SOAP Enterprise SOA (message-oriented)
SOAP uses two agreements being widely used: HTTP and an XML (son under standard generalized markup language
Collection).HTTP is for realizing the transmission of the RPC style of SOAP, and XML is its coding mode.Using several line codes and an XML
Resolver, HTTP server (IIS or Apache of MS) become the ORBS of SOAP at once.SOAP communications protocol is sent out using HTTP
Send the information of XML format.The agreement of HTTP and RPC is much like, it is simple, configuration is extensive, and to firewall than other agreements
It is easier to play a role.HTTP request is generally handled by web server software (such as IIS and Apache), but more and more
Application server product is supporting HTTP.XML is as a better network data expression way (NDR).SOAP is XML's
Request and response parameter coding mode are turned to using code, and is transmitted with HTTP.Specifically, a SOAP method can letter
Singly regard the HTTP request and response for following SOAP coding rule as, a SOAP terminal is then considered as one based on HTTP's
URL, it is used to the target that recognition methods is called.As CORBA/IIOP, SOAP does not need specific object binding to one
Given terminal, but the object object terminal identifier image to server end is decided how by specific implementation program.
Using state as angle, propose to propose the mode that state migration to first end is handled into that is both suitable for a first end application
Again suitable for the application of second end, unified Web view.It is suitble to B/S C/S S/S.Between HTTP first end and HTTP server
Difference, it doesn't matter for framework.One software can should not only serve as Web first end but also serve as Web server, and need not adopt
With two sets of entirely different APIs.
The unification of resource operating methods: POST, GET, PUT, DELETE is provided, is driven with hypertext or hypermedia
(hypertext/Hypermedia) state transfer is REST framework core.Operation brings state change, state transfer traversal
It is realized using link navigation mode.
The protocol conversion of ESB, homologous ray does not use different agreement, such as EJP, B system that A system uses to use
The RMI etc. that email, E system that webservice, C system use servlet, d system to use use.
The agreement that ESB is supported has:
HTTP, HTTPS, POP, IMAP, SMTP, JMS, AMQP, TCP, UDP, SMS etc.
Protocol conversion identifies that message transformation is the agreement that first end needs according to content type by Transport, then
It is transmitted.
Data conversion: the information of different-format, the load contents of operation information including encryption, compression are exchanged between application
And code conversion, message is formatted between the data type of the transport protocol of isomery.
Content-message routing is the core function of ESB, no matter business ESB product or increases income what ESB was mostly used greatly at present
It is fixed route, this is a kind of point-to-point routing mode, and hardness writes routing rule usually in request message header file,
Message based entrance determines the exit point of message, limits the flexibility of routing；In one embodiment, due to n
Service communicates with each other the channel that configure 0 (n) grade yearningly, as the increase , Pei Catching-rabbits the file information of quantity of service exponentially increases
Add, causes the decline of performance；Therefore routing (Content-based Routing, CBR) algorithm based on content, reduces and is
The cost of system and configuration is flexibly, improves the real-time responsiveness of system.
In one embodiment, which also includes encrypting module, such first end or second end and data
Preset cryptographic protocol is based on using encrypting module when management platform information interaction to be encrypted, when guarantee information is transmitted in this way
Safety.
In one embodiment, which also includes memory module connected to it, to store conversion
Information.
It is illustrated in figure 3 the flow diagram of the system of the data management platform of one embodiment of the application, is applied to
One typical SOA occasion end to end:
The system includes first end, data management platform, second end,
Information exchange is carried out between the first end and data management platform, and information friendship is carried out between data management platform and second end
Mutually.
In present embodiment, second end Service Provider issues Web Service in a manner of SOAP/HTTP,
Web Service input and return are all Java Object, and first end is gone to call Web Service in a manner of JMS, be needed
Data management platform (ESB) is first passed through, carries out protocol conversion, data conversion by the ESB.ESB is based on default rule for JMS
Protocol conversion is the SOAP/HTTP agreement that second end needs.The data that second end returns turn SOAP/HTTP agreement by ESB
It changes JMS agreement and is being sent to first end.In present embodiment, message routing is disappeared based on message content and complex rule routing
Breath, filtering, polymerization and the rearrangement of message.
