Description

The local side value automatic setting method of atm network

Technical field

The present invention is a kind of local side value automatic setting method of atm network, particularly be used in the xDSL data set method of the virtual route discre value (VPI) of ISP local side/tunnel discre value (VCI) and encapsulation (Encapsulation) capability value under the automatically setting atm network framework about a kind of.

Background technology

Send out long because of the flourishing of computer network at present, make many network technologies that considerable progress all be arranged, and some procotols are through fermenting over a long time, also oneself gradually is gesture ready to appear, as (Asynchronous TransferMode ATM) promptly is a wherein tangible example to be used in same transfer mode of non-step in the ADSL data network.

The practice of legacy network is with the data load transmission medium, and all machines that this transmission medium is required to be on the consolidated network are shared, so must possess whether the leave unused ability of (idle) of network of judging on each machine.That is to say, when the machine that other is arranged on network when transmitting data, system must wait for a period of time and could carry out the transmission operation of data again; And the appearance of atm network has improved this situation, and reason is that atm network uses switch (Switch) to reach point-to-point network on-line, makes the machine of receiving terminal and transmission end can enjoy this single online network bandwidth simultaneously.

At present, general network data all is that the mode with package (Packet) transmits, then the length scale of package is inconsistent, therefore the network equipment can cause the delay of different time in the transmission package, that is, when the scale of network heals when big, the time delay benefit also just more is not easy estimation.

Yet have more and more many images and GDF also to utilize network to transmit, this can produce sizable time delay to network, is equivalent to produce a large amount of noise jamming.Also therefore, because of the not of uniform size of package causes, make legacy network in the transmission of figure, voice etc., become one to hinder greatly.

For solving this puzzlement that causes the network traffic congestion, atm network is the little package (cell) that uses regular length, owing to be with the little package (cell) of the regular length unit as exchanges data, thereby the speed of switch has just also promoted manyfold.In other words, atm network promptly is to utilize little package (cell) to improve transfer rate, postpones variation significantly to shorten time delay and to relax.

On the other hand, legacy network is to use the hardware address mode to finish the function of Data Link Layer (Data Link Layer), and this is because of the hardware address of each machine is neither identical, and its also do not have each other can be corresponding association.And the height independence of machine hardware address can't obtain enough information by an easy algorithm with the system that makes, to understand the place, address of receiving terminal; And the machine of data transfer also only can utilize hardware address data to be delivered on the equipment such as router,, then must be dependent on network layer (Network Layer) and handle to receiving terminal as for the path that how to determine transfer of data.

Generally speaking, in the flow direction of network layer handles data, will consume the more computational resource of processor.Relatively, carry out data computation in network layer, the computing of the required execution of processor also is quite complicated.Therefore, processor does not have enough computing capabilitys, the bottleneck when then router tends to become Network Transmission.

In addition, router can be handled each package and decide its path.For instance: in the system of heterogeneous networks, if the transmission end with receiving terminal set up online after, any one package that is transmitted between them all need be delivered to the computing that network layer repeats the path, even all packages that come and go all navigate on the identical path.

Therefore, atm network is to use virtual join (Virtual Connection) to change traditional route pattern, repeats to be sent to the calculating of network layer execution route to avoid the package on the fixed route.The idea of virtual join is to use the first stroke data to set up double-pointed path, and all transmission data are then directly passed through switch processes by an authentication mode between two end points thereafter.

Yet ATM is in partly not standardization as yet of LAN (LAN) now, the data format that is ATM is still undefined fully, but the application of some big event and ATM is closely bound up, these field projects comprise: virtual route identification (Virtual Path Identifier, VPI), Virtual Path identification (Virtual Channel Identifier, VCI), the load kenel (Payload Type, PT) and little package abandon precedence (Cell Loss Priority, CLP) ... or the like.ATM switch utilizes the VPI/VCI field data to be directed to suitable output port the little package (Cell) of input port gained.

Because the VPI/VCI field length is short, and corresponding relevance is arranged, this for the flow direction of little package (Cell) output with easier processing, and the little package (Cell) of the Virtual Path identification (VCI) of all tool same field character group, can form tunnel (Virtual Channel), in like manner, the little package (Cell) of identical virtual route identification (VPI) group also forms virtual route (Virtual Path).

But because atm network is still undefined fully, so various countries, even the data format of each department different I SP local side, all different set points might be arranged, different as the VPI/VCI field value of Taibei local side and Beijing local side, even encapsulation (Encapsulation) capacity all might be inequality, therefore when setting up the atm network on-line terminal, must install and set action by ISP local side dealer, also therefore the modulator-demodulator of xDSL client can only be used in the transcriber of identical local side, and can't move arbitrarily, move to local side in the platform as Taibei local side, perhaps move to the U.S. by the Taibei.

Therefore, the inventor is the data set that solves above-mentioned existing atm network can't move inconvenience and the shortcoming that is had arbitrarily, be that the spy concentrates on studies and cooperates the utilization of scientific principle, a kind of virtual route value automatic setting method of atm network is proposed, the virtual route identifier (VPI) of automatically setting and ISP local side/tunnel identifier (VCI) and encapsulation (Encapsulation) capability value equal in the data set, can become the online of atm network, so be for one reasonable in design and can effectively improve the invention of above-mentioned disappearance.

Summary of the invention

Purpose of the present invention mainly provides a kind of local side virtual route identification (VPI)/tunnel identification (VCI) and set point automatic setting method such as encapsulation (Encapsulation) capacity etc. of atm network, can remove user or ISP dealer from needs the configuration and setting when installation to move, and can directly connect to the internet, therefore can be arbitrarily with this data set telephone-moving to Anywhere, even external as move to the middle and high hero of platform by the Taibei ... Deng.

For reaching foregoing invention, the present invention mainly provides a kind of local side value automatic setting method of atm network, be used in the data set atm network with automatically connect to ISP local side, this method is at first built in this data set and is put an automatic configuration table, be preset with the virtual route identification (VPI) of this ISP local side of plural number in it, the set point of Virtual Path identification (VCI) and encapsulation (Encapsulation) capacity, when using online this ISP local side of this data set to surf the Net, specify any one group of set point in the automatic configuration table, and login the ISP local side of this atm network with this set point, then send one and comprise this virtual route identification (VPI), the set point test packets of this Virtual Path identification (VCI) and encapsulation (Encapsulation) capacity is to this ISP local side, to wait for the test result of this ISP local side passback, when the online failure of test then exchanges to another group ISP local side set point again, until online success.

Reach technology, means and the effect that predetermined purpose is taked in order to make your auditor can further understand the present invention, see also following about detailed description of the present invention and accompanying drawing, believe purpose of the present invention, feature and characteristics, go deep into and concrete understanding when getting one thus, yet appended graphic reference and the explanation usefulness of only providing not is to be used for the present invention is limited.

See also shown in Figure 1ly, be the configuration diagram of atm network of the present invention.The present invention mainly is to use one with asynchronous transfer mode (Asynchronous Transfer Mode, ATM) be in master's the Wide Area Network framework 10, but not promptly being these atm network 10 applied a kind of broadband networks, symmetrical figure user loop (ADSL) dials and connects technology, general ISP local side 20 is provided with at least one ATM switch 21, access multiplexer (Digital SubscriberLine Access Multiplexer as digital user, DSLAM) as the equipment that accesses that inserts ADSL data set 30, can be with the transmission data of ISP local side according to virtual route identification (Virtual PathIdentifier, VPI) (Virtual Channel Identifier VCI) 32 is multiplexed in the atm network 10 in 31/ Virtual Path identification.

And the present invention mainly can be with the set point automatic settings such as encapsulation (Encapsulation) capacity 33 of virtual route identification (VPI) 31/ Virtual Path identification (VCI) 32 of this ISP local side 20 and data packet in a data set 30, as xDSL modulator-demodulator (Modem), router (Router), gateway (Gateway), IP Wireless Router (Sharing) or wireless network base stations (Access Point, AP) ... or the like, and do not need the ISP dealer to be set in the data set for the client at different atm networks.

Therefore, use data set of the present invention can move on demand in any network based on the ATM framework, as ADSL Modem is moved to the U.S. etc. by the Taibei, and automatic configuration of the present invention is set the burden that can help the client to reduce setting changing, as long as the client has in local ISP local side application ADSL service.

See also shown in Figure 2ly, be establishing method schematic flow sheet of the present invention.At first the present invention builds in this data set 30 and has put an automatic configuration table, comprised the virtual route identification (VPI) of the default ISP local side of plural groups in this automatic configuration table, the set point (S100) of Virtual Path identification (VCI) and encapsulation (Encapsulation) capacity, the virtual route identification (VPI) that may use, the set point of Virtual Path identification (VCI) and encapsulation (Encapsulation) capacity is built in advance and is put in this automatic configuration table, as the VPI/VCI set point in the Taibei, VPI/VCI set point in the platform, the VPI/VCI in the VPI/VCI of Pekinese set point or New York sets ... or the like.

After data set 30 of the present invention connects at least one computer, and when in this computer, starting a network on-line software, as the software of a browser software, an EUDORA or any tool network on-line function, can be by these data set 30 dialing connections to this ISP local side (S102).

At this moment, this data set 30 can be specified this virtual route identification (VPI) of any one group of this ISP local side in this automatic configuration table of use and the set point of this virtual route of retreat identification (VPI) and encapsulation (Encapsulation) capacity, as the set point that is online to the ISP local side (S104).

And the set point of this virtual route identification (VPI) and this Virtual Path identification mainly can be calculated to avoid network layer to repeat route in order to the transmission path and the channel of data packet in the rapid decision atm network.And the set point of this encapsulation (Encapsulation) capacity is the amount of capacity in order to the data packet (Cell) of decision atm network.

Then, sending the online information of a test holds to the user, and the set point of complying with arbitrary group of virtual route identification (VPI) in this specified automatic configuration table, this Virtual Path identification (VCI) and encapsulation (Encapsulation) capacity is logined the ISP local side of this atm network, and send a test packets to this ISP local side, wait for the test result (S106) of this ISP local side passback.

But if the test result of ISP local side passback is failed, then in automatic configuration setting table, exchange to virtual route identification (VPI)/Virtual Path identification (VCI) and encapsulation (Encapsulation) capacity set point (S108) of another group, proceed online testing (S106) again, until online success.

If test virtual route identification (the VPI)/Virtual Path identification (VCI) of this ISP local side passback and the online of encapsulation (Encapsulation) capacity set point are successful, then do not do any change, and the online successful information of sending is to the computer of user's end.

Then, again with a PPP(Point to Point Protocol) (Point to Point Protocol overEthernet, PPPoE/Point to Point Protocol over ATM, PPPoA) Yu She user's number of the account and password are online to ISP local side (S110), if the information (S112) of requirement input user's number of the account and password is then sent in the online failure of PPPoE/PPPoA; After the user inputs user's number of the account and password, store this user's account number cipher default value, and again online PPPoE/PPPoA to ISP local side (S110), set and to finish if online success then sends one, the information that has been online to the internet (S114) to the computer of user's end.

But when if the set point of all these default virtual route identifications (VPI) in this automatic configuration table, this virtual route of retreat identification (VCI) and encapsulation (Encapsulation) capacity all can't be online to this ISP local side, the information of then sending online testing failure is held to the user, and requires the user to check network on-line or seek ISP dealer's assistance (S116).

User of the present invention from the above has four kinds of different situations in use:

Situation 1: the user will see the information that shows present online detecting on the picture of computer, as Fig. 3 when logining network on-line.
