Description
Technical field
The present invention relates generally to the aberrations in property in identification high speed data transmission system and the assembly and the reason of other problem.More specifically, embodiments of the invention relate to configurable diagnostic module, and it can carry out the various different diagnostic tests that are suitable for various different network protocol and configuration.
Background technology
Computing machine and data communication network are owing to cost decline, computing machine and the networking equipment performance increases and the increase in demand of communication bandwidth is continued surge.By processing in resource sharing, voice-and-data transmission and voice, data and the relevant information of the position of full blast, communication network-comprise wide area network (" WAN "), LAN (Local Area Network) (" LAN ") and storage area network (" SAN ")-permission distributed computer or the throughput rate at station and increase of utilization factor.And, along with each tissue is recognized the economic interests of using communication network, be used as the means of increase customer productivity day by day such as the network application of Email, voice-and-data transmission, host access and shared and distributed data base.The demand of this increase has caused having installed the rapid expansion of the number networks together with the quantity of the growth of Distributed Calculation resource.
Along with the demand growth to network, network technology has developed into the degree that has many different physical configuration at present.Example comprises Gigabit Ethernet (" GE "), 10GE, Fiber Distributed Data Interface (" FDDI "), optical-fibre channel (" FC "), synchronous optical network (" SONET ") and InfiniBand network.These and other network typically meets one of the various standards of having set up or agreement, described standard or agreement propose between supervising the network visit and the Internet resources with among the rule of communicating by letter.Typically, the wiring system that such network utilisation is different, the bandwidth that takes on a different character, and typically with different speed transmission datas.Particularly the network bandwidth has become the pushing factor of many progressive back in high-speed communication system, method and apparatus field.
For example, the ever-increasing demand of the network bandwidth having been caused increasing can be by the development of the technology of the data volume of single passage propelling movement on the network.But the progress of modulation technique, encryption algorithm and error correction has greatly increased the speed of data inter-network transmission.For example, before several years, the flank speed that data can be striden an Internet communication is about per second one gigabit.This speed has been increased to data can stride the degree that Ethernet and SONET propagate up to per second 10 gigabits or faster rate.
Yet along with the increase of communication network on size, speed and complexity, they have become may produce the various verified in practice problems diagnosing and solve of being difficult to day by day.Consider that such problem has special significance to the lasting demand of the network capacity of high-level network work reliability and increase.
The common problem that experiences in network service can have various forms and can be used as the result of various varying environments and take place.Give some instances, can cause the example of environment, situation and the incident of network communication problem to comprise the transmission of unnecessary little information frame, poor efficiency or incorrect route, unsuitable network configuration and the too much network traffics of information.Owing to the growth of new network topology and agreement, reconfigure and introduce, such problem is aggravated because network continues variation and succession.And new network interconnection apparatus, network interconnection and software application are constantly introduced and are implemented.Needs have been given prominence to such as these environment to efficient, reliable and flexible diagnosis mechanism.
Therefore, along with the maturation of high-speed data communication system, method and apparatus, many designs are primarily focused on reliability and the performance issue day by day.Correspondingly, many diagnostic devices and test be used in identification just causing network depart from the existing network situation of expected performance and initiatively identification network condition two aspects that can cause network to depart from expected performance in the future help network manager.
A kind of equipment that is used for the recognition network situation is protocol analyzer, also is called network analyser.Usually, protocol analyzer moves in net background, catches, checks and write down the bag flow.Protocol analyzer can for example be configured to monitor unusual IP address, timestamp and packet, and has mostly and make network manager can visit the user interface of information of the expression analysis that protocol analyzer carried out.Therefore protocol analyzer is to be used for test and to debug various types of communication networks, comprises the useful substantially and very instrument of calculating and computer storage networks.
Protocol analyzer is by from partly coming work via catching selected data the communication network data flow transmitted.The information of being caught can be analyzed to extract information needed in more detail by protocol analyzer then.For example, being commonly referred to the data transmission fault of situation of problem or error or performance error can diagnose by checking the catch data relevant with this problem.
The equipment that another kind is used for the recognition network situation is generator.Usually, generator generation network traffics are come simulate various network conditions.For example, generator can produce the network traffics of two data between nodes streams on the artificial network.Can assess the behavior of other node of described two nodes and network, how the data stream of institute's emulation be made response to determine network.Like this, network manager may can the recognition performance deviation and is taken appropriate measure to prevent take place in the future aberrations in property.
The equipment that another kind is used for the recognition network situation is bit error rate tester.Usually, bit error rate tester is worked by predetermined bit sequences is transferred on the data transfer path, and when described predetermined bit sequences turns back to bit error rate tester it is analyzed then.Typically, such analysis comprises that the copy of the bit sequence that will be received and the original transmission bit sequence to the data transfer path compares.This relatively allows the error in the described sequence to be discerned and count.After to the error count in the bit sequence, described information is used to calculate total bit error rate (BER).If bit error rate (BER) is too high, then should check data transfer path and Physical layer thereof.The standard expectation bit error rate (BER) of some agreements is lower than a particular value.
The equipment that another kind is used for the recognition network situation is interference unit.Usually, interference unit provides the ability of optionally changing channel data, comprises error is incorporated in the channel data path.Like this, interference unit allows the response of monitoring communication system to the change data, and helps to determine whether communication system can make response, and does not experience the adverse effect of performance, as data loss or network traffic interruption.For example, network system designer can carry out in many different diagnostic tests any one determine whether task or sequence imperfect, that misplace or omit are suitably made response such as system, how to dispose misleading or chaotic frame, and the ordered set of misplaced how.
Protocol analyzer, generator, bit error rate tester and interference unit (and miscellaneous equipment of possible test network situation) may be implemented on the printed circuit board (PCB) (usually being called " card " or " blade (blade) ") that is inserted in the computer system test chassis.Depend on required functionally, the supvr can be inserted into the card of particular type in the computer system test chassis.For example, when the supvr wants the network test bit error rate (BER), this supvr can be inserted into the bit error rate tester card in the computer system test chassis.Subsequently, when the supvr wanted the phase-split network flow, this supvr can remove the bit error rate (BER) test card and the network analyser card is inserted in the described computer system test chassis from described computer system test chassis.
Some computer system test chassis even comprise a plurality of card sockets make computer system test chassis can hold many cards.Like this, the supvr can have while certain dirigibility at the various network conditions test network.For example, the supvr can comprise generator card and jammer card in many receptacle computer system test chassis, to utilize generator and interference unit functional simultaneously.Regrettably, along with the expansion of network and/or reconfigure, can change to the requirement of test network.The expansion of network and/or reconfigure can cause the supvr must, at least often remove and replace card in the computer system test chassis.If computer system test chassis lacks the socket of sufficient amount, may need the supvr to change card with the frequency that increases, or even the additional test chassis of acquisition.
Always there is the supvr to lack to be used to certain opportunity of the card of carrying out particular diagnostic function.Like this, may need the supvr to obtain independent card, even one or more diagnostic function is not frequently carried out at each required diagnostic function.For example, in addition once utilize every month interference unit functional, will still need the supvr to use jammer card.Also can need the supvr to obtain independent card, even one or more agreement is not frequently used at each required agreement.For example, the problem in the diagnosis fiber channel network will need the supvr to use the fiber channel protocol analyzer, and in order to diagnose the problem in the Gigabit Ethernet network, will need the supvr to use different Gigabit Ethernet protocol analyzers.
And, when the card of making at particular diagnostic function is out of order, generally needs the supvr to buy and replace card.In addition, if any, the functional mechanism that is used to revise card is limited.For example, the function of jammer card being carried out instead the bit error rate tester card generally is quite difficult.Therefore, it will be favourable being used for providing the functional of many diagnostic devices and the system, the method and computer program product that are used for several different agreements of single card.
