Description
Technical field
The present invention relates to the technology of cluster device transfer files, particularly a kind of method and document transmission device of cluster device bulk transfer file.
Background technology
In communication system, a kind of technology of application network equipment is arranged, as using the technology of Ethernet switch equipment, this technology is connected to each other many network equipments, forms a cluster device group.In management layer, the cluster device group is an integral body, wherein, have in the cluster device group nucleus equipment respectively with the cluster device group in miscellaneous equipment directly or indirectly be connected, be used for miscellaneous equipment in the management cluster equipment group, nucleus equipment in the cluster device group is called command facility, and miscellaneous equipment is called member device.
The function that the cluster device group can realize mainly comprises: the first, and the plug and play of member device, the cluster device group can be found and add to a member device that has just dispatched from the factory just as long as be connected with command facility by command facility; The second, the unified management of member device, the keeper can not need to the member device scene member device to be managed or disposes by command facility management or configuration member's equipment, has reduced management cost, has improved allocative efficiency; The 3rd, batch documents is downloaded, and command facility may be calculated once for many member devices and downloads publicly-owned file simultaneously, improves download efficiency; The 4th, the remote failure location when member's device fails, can be found the member device of fault by command facility, reaches the purpose of quick fault location equipment; The 4th, save publicly-owned Internet protocol (IP) address, whole cluster device group provides a public ip address to the communication system of outside, and the public ip address that the equipment in the outside communication system passes through to be provided adds command facility and each member device in each device identification (ID) visit cluster device in the cluster device group.
Because the quantity of member device is more in the cluster device group, Regional Distribution is wider, when the upgrading member device, need to use the notebook computer that stores upgrade file each member device to be upgraded to each the member device scene in the cluster device group, this is a very loaded down with trivial details process, and the main purpose of setting up the cluster device group is the streamlining management operation, reduces the maintenance cost of equipment.Therefore, in the streamlining management operating process, it is exactly the technology of the cluster device bulk transfer file in the cluster device group that a very important bookkeeping is arranged, and particularly carries out the technology of bulk transfer upgrade file at the member device in the cluster device group.
The method that the technology of the cluster device bulk transfer file in the employing cluster device group is upgraded to the member device in the cluster device group has two kinds.
First method, the file server of a carrying upgrade file is set, this document server adopts the mode of Telnet to sign in to successively by the command facility in the cluster device group on the member device in the cluster device group that needs upgrading, upgrade file is downloaded to each member device in the cluster device group upgraded.In order to improve the utilance of this document server, this document server is arranged on the outside of cluster device group usually.According to the implementation of cluster device group processing file, the file of downloading to each member device in the cluster device group all needs through command facility.
Second method, the file server of a carrying upgrade file is set, the member device of command facility in the cluster device group in the cluster device group sends the software upgrading order, this order carries the file server address of carrying upgrade file and the path of upgrade file, after member device in the cluster device group receives orders, be remotely logged into the file server that has carried upgrade file simultaneously by the command facility in the cluster device group, the download and upgrade file is upgraded.Similarly, in order to improve the utilance of this document server, this document server is arranged on the outside of cluster device group usually.
But all there is shortcoming in these two kinds of methods.The shortcoming of first method is: at first, the file server of carrying upgrade file need sign in on the member device that will upgrade in the cluster device group successively, quantity increase along with member device in the cluster device group, the manipulation strength straight line rises, and is easy to cause the misoperation of the file server that carries upgrade file; Secondly, upgrading efficient is low, all is serial to the escalation process of member device in the cluster device group, can cause the problem to the escalation process overlong time of whole cluster device group.The shortcoming of second method is: at first, command facility load in the cluster device group is very big, because the member device in the cluster device group is simultaneously by the command facility download and upgrade file in the cluster device group, can cause the serious overload of command facility load in the cluster device group, finally cause the operation exception of whole cluster device group; Secondly, if in order to alleviate the command facility load pressure in the cluster device group, must limit the quantity of the member device that will upgrade in the cluster device group each time, under a fairly large number of situation of the member device that will upgrade in the cluster device group, just need a plurality of member devices in the cluster device group to upgrade in batches, this can make the escalation process overlong time of whole cluster device group, as several hours, in this process, the load of the command facility in the cluster device group is all very big always, and this can cause the decreased performance of whole cluster device group.
Therefore, how to guarantee that the bulk transfer document time is short and to reduce under the load condition of command facility in the cluster device group that member device bulk transfer file, particularly upgrade file in the cluster device group become a problem demanding prompt solution.

Command facility in the cluster device group of the present invention is provided with rank and storage according to the topological structure of cluster device group respectively to each member device in the distinct device type of cluster device group.
The present invention can be according to the member device rank in the distinct device type of determining the cluster device group according to following steps.
At first, the device type independence divided rank different, i.e. different members equipment independence divided rank in the distinct device type according to member device in the cluster device group.This be because, may be different at the file of the member device bulk transfer in the distinct device type.
Secondly, for the different members equipment in the same device type, be root node with the command facility in the cluster device group, determine the grade of member device according to the member device in the cluster device group to the jumping figure of command facility, jumping figure is few more, and grade is high more.For example: when the member device in the cluster device group when the jumping figure of command facility is 1, giving the grade of this member device setting is 1; When the member device in the cluster device group when the jumping figure of command facility is 2, giving the grade of this member device setting is 2.
At last, for the identical different members equipment of jumping figure in the same device type, that arrive command facility, command facility is treated with a certain discrimination: if these different member devices are competition first order equipment, promptly the grade of She Zhiing all is 1, then select the member device of member id minimum to be the first order equipment in this device type, other member device is the second level equipment in this device type; If these different member devices are not competition first order equipment, promptly the grade of She Zhiing is not 1, then that these are different member devices classify as in this device type the peer device of definite grade.For the different different members equipment of jumping figure in the same device type, that arrive command facility, will be the rank of the determined grade of member device as this member device.
Fig. 1 is the topological structure schematic diagram of cluster device group of the present invention, below with Fig. 1 be example explanation the present invention be how for the different members equipment in the cluster device group be provided with level other.
In the drawings, suppose that member device 1, member device 4, member device 5, member device 6 and member device 7 are the member devices in the same device type, member device 2 and member device 3 are the member devices in the same device type.

Secondly, for member device 1, member device 4, member device 5, member device 6 and member device 7, as root node, determine grade according to the jumping figure to command facility with command facility: member device 1 is 1 to the jumping figure of command facility, is 1 for member device 1 is provided with grade then; Member device 4 and member device 5 are 2 to the jumping figure of command facility, are 2 for member device 4 and member device 5 are provided with grade respectively then; Member device 6 and member device 7 are 3 to the jumping figure of command facility, are 3 for member device 6 and member device 7 are provided with grade respectively then.For member device 2 and member device 3, as root node, determine grade according to the jumping figure to command facility with command facility: member device 2 and member device 3 are 1 to the jumping figure of command facility, are 1 for member device 2 and member device 3 all are provided with grade then.
At last, for the identical different members equipment of jumping figure in the same device type, that arrive command facility, command facility is treated with a certain discrimination: for the member device in the same device type 1, member device 4, member device 5, member device 6 and member device 7, in the 1st grade, has only member device 1, so member device 1 is exactly the first order equipment in this device type; Member device 4 and member device 5 are not competition first order member devices, so member device 4 and member device 5 all are the second level member devices in this device type; Member device 6 and member device 7 are not competition first order member devices, so member device 6 and member device 7 all are the third level member devices in this device type.For member device in the same device type 2 and member device 3, member device 2 and member device 3 are competition first order member devices, so select the little member device 2 of member id as the first order member device in this device type, select the big member device 3 of member id as the second level member device in this device type.
In the present invention, for the member device in the same device type, also can be set to the member device of the 1st grade to the member device of the jumping figure maximum of command facility, the big more then grade of jumping figure is high more.
In the present invention, for in the same device type, can not treat with a certain discrimination to member device, the command facility of the equal jumping figure of command facility yet, and directly all be set in this device type the same level equipment of definite grade, also can distinguish rank according to Else Rule.
In the present invention, also can be with the not independent divided rank of the member device in the distinct device type, and, still, when transfer files, distinguish the distinct device type of member device directly with all member devices in cluster device group divided rank together.
After command facility in the cluster device group of the present invention has been stored the rank of each member device in the cluster device group, just can the bulk transfer file.
In the present invention, command facility also can not distinguished the distinct device type of member device, and directly gives the member device divided rank according to the method described above.
Fig. 2 is the flow chart of cluster device bulk transfer file of the present invention, and its detailed process is:
Carry the equipment in the communication system that the file server that carries file is cluster device group outside.
In the present invention, also storage file not of the member device of afterbody.
In the prior art, all store the information of each member device file in download of login such as address, file path, login username and password of each member device in the command facility in advance, thereby command facility can be when sending the transfer files instruction, carries the user name of address, file path, login upper level member device of the upper level member device in the distinct device type and password etc.Certainly, when useless name in an account book of upper level member device and password, the information that the transfer files instruction is carried also can not comprise the user name and the password of upper level member device.
In the present invention, other member device of each grade in the distinct device type can be stored in downloaded files in the file path of appointment, as be stored in the flash memory (flash) or hard disk of member device, this document routing information is stored in command facility at this member device, so that when command facility sends the transfer files instruction for the next stage member device, the file path information of carrying this member device.Certainly, the present invention also can internal memory with other member device of each grade of downloaded files device storage in the distinct device type in, at this moment, command facility sends the file path information that the transfer files instruction need not be carried this member device for the next stage member device.
When transfer files, command facility can adopt the described method of Fig. 2 to each member device transfer files in all distinct device types of cluster group; Also can adopt the described method of Fig. 2 to each member device transfer files in a part of distinct device type of cluster group.To each member device transfer files in a part of distinct device type the time, command facility is as long as issue the transfer files instruction for each member device in determined a part of distinct device type, and this transfer files that issues instruction can also be carried the sign of device type.
The present invention be exactly with in the cluster device group when the prime member device as bridge, the transfer files of one-level level, whole process is actually: at first, set first order member device is file in download and storage on the file server that signs in to the carrying file under the control of command facility by command facility; Secondly, begin to sign in to file in download and storage on the upper level member device at current rank member device under the control of command facility till the determined penultimate stage member device from set second level member device; At last, set afterbody member device is signing in to file in download on the penultimate stage member device under the control of command facility.
