Description
Technical field
The invention belongs to field of computer technology, be specifically related to a kind of local area network (LAN) that sets up based on Mobile operating system.
Background technology
Along with the development of computer networking technology with popularize, computer network has become a requisite part in the information-intensive society.The maturation of Internet provides an omnifarious wonderful stage to us, is local area network (LAN) but really make network penetration to the social life every nook and cranny.No matter be in community, in school, still in enterprises and institutions, local area network (LAN) can both satisfy user's requests such as network management, resource-sharing, information interchange well; Interconnected by with the internet simultaneously, local area network (LAN) can become the extension of Internet again.
The hardware of local area network (LAN) sets up generally to be made up of three parts: server end, client terminal, network access device.At present mainly contain following two class scheme of architecture:
1, traditional scheme of architecture, " fat client " is the basic thought of this scheme.Client terminal is selected for use and is disposed home computer preferably, and all on this machine of client hard disk, the user independently finishes most operation in client for operating system and application program.And the effect of server end is mainly reflected in the control, management, maintenance of network, and used server configuration requirement is not high.
2, " no dish-type " scheme of architecture, " thin client " is the basic thought of this scheme.As its name suggests, in this scheme client terminal configuration relatively low, and need not hard disk, on the basis of network startup, must finish all operations at server end by Telnet.And server end so the performance of server is extremely important, generally all must be selected the higher type of configuration owing to will handle the request of a large amount of clients.Simultaneously, this scheme also requires quite high to the performance of network access device.
These two kinds of schemes can be described as respectively quality: traditional scheme is realized simple, but the cost height, and be difficult to administer and maintain; " no dish-type " scheme has reduced cost, simplified management, but the server end load is too big, and stability is not good enough.
Summary of the invention
The objective of the invention is to propose the local area network (LAN) of a kind of with low cost, convenient management, good stability.
The local area network (LAN) scheme of architecture that the present invention proposes is on the basis of existing local area network (LAN) scheme of architecture, the modified model scheme of maximizing favourable factors and minimizing unfavourable ones and being produced.The mode that it adopts Mobile operating system to combine with remote terminal control.In this scheme, client terminal adopts with " no dish-type " scheme of architecture does not similarly have the hard disk workstation configuration, realizes the startup of this machine and enters Mobile operating system by flash disk.Because Mobile operating system itself provides application program commonly used, the user just can finish part operation at this machine.And simultaneously, server end is then installed some calculation of complex or the bigger application program of capacity, and client can be finished the operation of this part by remote terminal control, and realizes resource-sharing.Claiming that the present invention is " U-start type " scheme of architecture, is a kind of local area network (LAN) scheme of architecture based on Mobile operating system.
Because " U-start type " scheme of architecture is a kind of improvement project, thus its advantage can from the comparison of existing scheme draw.
At first, compare with traditional scheme of architecture, " U-start type " scheme has the advantage of following several respects:
1, cost is low.With respect to about 4000 RMB of client terminal in the traditional scheme/cost of platform, in " U-start type " scheme about client terminal 1500 RMB/cost of platform is much lower.And along with the increase of client terminal number in the local area network (LAN), the cost that can save is appreciable.
2, manageability.Hard disk management in the traditional scheme on the client terminal is very complicated: on the one hand, increase application program at every turn and all must on every client terminal configuration be installed; On the other hand, a large amount of hashes, program and computer virus more need regularly to remove.In addition, because hard disk failure rate under frequent situation about using is higher, again must the no small maintenance spending of burden.And " U-start type " scheme does not have such problem fully: Mobile operating system itself just returns the user to own, by the own management maintenance of user; Increase application program and only configuration need be installed on server few in number, need the memory space of management also to be only limited to server end, can save many manpower and materials.
3, energy consumption is low.In view of the massive blackout incident that not long ago once took place in the North America, the energy consumption problem of computer (the particularly computer cluster as the local area network (LAN)) more and more comes into one's own." U-start type " scheme of architecture makes the energy consumption of whole local area network reduce greatly owing to use flash disk to substitute the memory device of conventional hard as client, has reached purpose of power saving.
In addition, compare with " no dish-type " scheme of architecture, " U-start type " scheme has the advantage of following several respects again:
1, alleviates the load of server end, increased the stability of whole local area network.
2, Mobile operating system has been arranged, the user can carry out exchanges data more easily.
3, reduced the configuration requirement of server and network access device, provided cost savings.
In sum, " U-start type " scheme of architecture has high performance-price ratio, stable, efficient, manageable characteristic, is a kind of more outstanding local area network (LAN) scheme of architecture.
Embodiment
Mainly comprise the customization of Mobile operating system and the realization of remote terminal control.
1, Mobile operating system.
Requirement is smart little, and safety is stable, beautiful interface, and hardware requirement is low, and can self-defined property strong, software be abundant.Based on above-mentioned consideration, decision is adopted (SuSE) Linux OS and is improved.Below be specific embodiments:
(1) BIOS (basic input output system, basic input output system)
A) power on self test (POST, Power-On Self-Test), self-checking system equipment
B) final stage of BIOS, read main boot record (MBR, main start record) to the particular memory address and redirect carry out.
C) mainboard can be with flash disk with the access of hard disk mode (to support what USB-HDD started).The flat storage of flash disk is modeled as common hard disk and conducts interviews with cylinder head sector (CHS, cylinder/magnetic head/sector) pattern.
(2) operating system
A) GRUB (a kind of Linux starts hypervisor) guiding kernel
We adopt GRUB rather than the general LILO that adopts (another kind of Linux starts hypervisor) to guide kernel.For visit and the startup of supporting USB, must carry out a series of changes and identification again in kernel.
