Error probability.Shown in Figure 1, the method for the present invention is architecturally on TUDP facilities network network layers, service logic
Under layer.Inventor devises following logic flow to the automatic discovering method of distributed component service in desktop cloud of the invention
Journey: in each node increase group stratum reticulare logic, after node component starting operation, the distributed component newly started multicast into network
A query messages are sent, the state of each component nodes is inquired；Message content contains the spy that desktop cloud and component itself are arranged
The data such as sign mark and the type, version, state of this node.Other distributed components having been turned on receive this message
After verifying signature identification, the data content received and preservation are parsed, while the relevant information of this component nodes is passed through into response bag
Return to sender.If component does not receive any response message, this query messages, Zhi Daoshou are regularly sent within every 5 minutes
To response message.For the spread scope for controlling multicast, multicast address be may be configured as in 239.0.0.0~239.255.255.255
Between, and ttl value (limiting the routing number that multicast packet passes through) is set, by multicast scope control in Intranet limited range,
The specific address (Internet Protocol) multicast IP and TTL (Time To Live) value, can set in advance in component installation kit
It is fixed.The content of response bag (i.e. response message) is initially set according to system, and can be there are two types of different type: one is response messages
(i.e. response message), which directly returns, agrees to (agree)；Networking causes confusion when to avoid same network segment from having more set autonomous systems, is
The response bag that system can also set each node only returns to message and has received (received) and registration confirmed, waits administrator's approval
Afterwards system retransmit an approval message by this node drawing (pull) enter in system.It is further detailed below by way of specific embodiment
Explanation.
The automatic discovering method of distributed component service, shown in Figure 2 in the desktop cloud of the present embodiment, including following step
It is rapid:
S10, multicast monitoring, and default multicast address and the routing number for limiting multicast packet process are established, to control group
The spread scope broadcast.
Specifically, system first establishes multicast monitoring mechanism, and the pre-configured multicast IP and TTL in installation kit, group
It broadcasts IP and is defaulted as 239.1.0.100, port default 10001, TTL is defaulted as 3, and system installer can decompress installation compression
It guarantees the repair free of charge and changes default configuration.
After S11, the distributed component being newly added starting, inquiry is sent into network with multicast mode as sender and is disappeared
Breath.
Specifically, sending a group to address 239.1.0.100:10001 first after the distributed component starting being newly added
It broadcasts inquiry request message (query messages are sent into network with multicast mode), requests to open in packet header with the 0x1111 of 4 bytes
Begin to follow the character string " RNET " of 4 bytes for mark, License (software license), the communication of component itself are contained in backpack body
The mesh informations such as protocol version, software version number, component type, component unique identification (using network interface card MAC).
Other distributed components in S12, network are as recipient, and after receiving the query messages, parsing is wherein
Data content and preservation.
Specifically, other nodes (other distributed components having been turned on i.e. in network) in system receive this request
Afterwards, it checks whether the data in packet header identifier and backpack body meet agreement, checks errorless rear preservation Correspondent Node information.
S13, the mesh information of this component is returned to newly by response message as other distributed components of recipient
The distributed component of addition.
Specifically, whether the settable system of system manager needs to examine the networking request of new node.If being set as needing
It examines, then the response message of other distributed components only returns to message and received (received) and registration confirmed, in system
Mesh information is just sent to New Parent by system after administrator's examination & approval.I.e. if preset policy definition divides without new be added of examination & approval
The networking of cloth component is requested, then other distributed components as recipient are by response message directly by this component
Mesh information returns to the distributed component of the new addition；If preset policy definition needs to examine new addition distributed group
The networking of part is requested, then after examining, then the response message is sent to the distributed component of the new addition.
S14, the new addition distributed component receive response message after, mesh information therein is saved in local match
It sets in file, in case networking uses again after restarting.
Specifically, if the distributed component being newly added does not receive the response message in preset duration, such as:
Response message is not received within 5 minutes, then send the query messages into network with multicast mode again, disappear until receiving response
Until breath.
S15, the distributed component being newly added use local profile according to own service logic, and to other distributions
Component initiates networking request, completes networking.
The advantages of the present embodiment, is as follows:
1. distributed component is not necessarily to any configuration after being installed, leads in nearly network and exist in component energy discovery system
Service, reduce the installation maintenance work amoun under cloud computing large scale deployment, than traditional services registration structure it is more intelligent, high
Effect.
2. each node component other distributed nodes in inquiry system by way of multicast, are scanned relative to IP one by one,
The data traffic in network can be effectively reduced, response and treatment effeciency are improved；And have relatively for the whole network broadcast smaller
Data dissemination range, avoid unnecessary interference.
3. having pre-seted multicast ip address, ttl value, installation personnel can modify multicast IP and TTL before component installation
The parameters such as value, according to grid situation flexible choice.
4. system manager can select the service-seeking for newly added node to request according to own situation, if need
Audit approval, or be directly added into system without examination & approval.
