Zone Protocol Conformance Research And Validation Based On TTCN-3

Computer can be used with communication technology in networks.Network realizes the remote communication,information interaction and sharing resources,and protocol in the network have been quite important.Entities in the distributed system with various communication shall comply with protocol.Protocol is the base of the network.With FCoE technology is widely applied in Storage networks,it happens to be more and more complicated structure of Storage networks,in addition to make network management and maintenance can be easy,many networks protocols appear.Now every protocol standards development commissions illustrate the network protocol through natural language,thus it brings much trouble to workers who develop protocol.According to view of developers,their understanding of the protocol standard is different,and there is a part of objective factors in the process of development.Eventually it makes the realization of the protocol will have many versions,and some wrong protocol appear.This paper mainly is about Zone protocol conformance test.Zone protocol is defined by the FC-SW-5.In addition to make realization of Zone protocol can be conformed to the rule of protocol,the influence of protocol conformance test is quite clear.Protocol conformance test is the foundation for other test.With the implementation of protocol,the testers should pay special attention to the test.In a series of protocol conformance test,TTCN is the most commonly used,it is actually a language test.It plays an enormous role in test and testers use is very convenient.In this paper,detailed description of the protocol conformance testing.Then The paper introduce the basic concept and its working mechanism and explains test set description of assembly language TTCN-3,testing system.And in this paper,it strictly follows the protocol test for the design of Zone protocol conformance test.It introduces the whole test related technology,and then the test carries on the demand analysis,the analysis of Zone protocol standards documents should be done to find out the most basic point to test and refines them as test requirement.The analysis of the protocol conformance test method should be done.When it has a profound understanding of the Zone protocol standards,working process and message structure,the design of Zone protocol conformance test can be done.According to the analysis of test requirements before the write test cases with echo,it uses the TTCN language to write the message template,function to send message,receive message function.Finally it is to write test set of test cases that echoes.Analysis of test results should be done.Protocol conformance testing system make the implementation Zone Protocol Conformance test automation,greatly reduce the test time and reduce the input of staff.At the same time management and maintenance of test system will be very convenient.If the protocol is changed,as long as the small scope changes to the test system,it can continue to be used.
