17383cd4c534115fe1b942c1f3517a28 | 101 667 | 5.1.4 Internationalization | The interconnection among network users involves more and more often networks managed/exploited by Service Providers of different nationalities, and under different normative regimes. |
17383cd4c534115fe1b942c1f3517a28 | 101 667 | 5.2 Deregulation and Competition | The shift from monopoly supply to an open competitive market in services and equipment causes an increase in the number of deregulated areas and an obligation to open and interconnect public networks in every country to other Network Operators and to network Service Providers. This change reached a major point in Europ... |
17383cd4c534115fe1b942c1f3517a28 | 101 667 | 5.3.1 Requirements | Potential interworking and interoperability problems could arise within a global infrastructure (or even among the NEs of a single network) when some changes are introduced somewhere in one network. A case could be a new set of [supplementary] services that enters into operation, or a new version of a protocol (e.g. IS... |
17383cd4c534115fe1b942c1f3517a28 | 101 667 | 5.3.2 Goals | The main purpose of NIT is to evaluate the overall behaviour of different networks and to increase the probability that the network services are supplied to the customers in a correct and reliable way. |
17383cd4c534115fe1b942c1f3517a28 | 101 667 | 5.3.2.1 Strategic objectives | Two are the major strategic objectives: a) to allow Network Operators to verify that their customers can be provided with the subscribed services when connected with users of other networks; b) to test the complex "global network" in a more direct and cost-effective way, by evaluating the behaviours of many Network Ele... |
17383cd4c534115fe1b942c1f3517a28 | 101 667 | 5.3.2.2 Technical objectives | From the technical point of view, the main objective of NIT is to verify the actual service provision to users of different connected networks, checking that the complex interworking between interconnected networks do not cause problems. The localization of the causes of any possible detected problem is just a (useful)... |
17383cd4c534115fe1b942c1f3517a28 | 101 667 | 6 What is actually testable with NIT? | The object of NIT is a network, or a part of it, made up by interconnecting two or more NEs. Heterogeneity is not a requirement for NIT, but the methodology is applicable to networks characterized by differences, like: a) NEs released from different manufacturers; b) different releases of a given NE; c) different kinds... |
17383cd4c534115fe1b942c1f3517a28 | 101 667 | 6.1 How is NIT used | Considering now some specific current technical domains and technologies, NIT has already been used in many companies in the areas of: a) ISDN and Mobile services (e.g. basic speech/data call and supplementary services); b) Broadband ISDN/ATM; c) Intelligent Network Applications (e.g. INAP); d) for the interconnection ... |
17383cd4c534115fe1b942c1f3517a28 | 101 667 | 6.2 End-to-End and Node-to-node testing | As already said, an End-to-End testing means to test the network as seen at the user accesses while a Node-to-Node testing means to test the network as seen from the network trunks. Therefore EtE is concerned only with the external behaviour of the network, while in NtN also the internal behaviour is object of testing ... |

17383cd4c534115fe1b942c1f3517a28 | 101 667 | 6.3.2 The NIT testing methodology | Despite it is also usable by Network Operators for testing their NEs and the services they offer, the CT methodology is probably more directly related to the core business of the Network Elements and Terminal Equipment Manufacturers and Suppliers. It is also relevant to Regulators. For Network Operators it is particula... |
17383cd4c534115fe1b942c1f3517a28 | 101 667 | 6.4 Some open issues of the NIT methodology | The NIT methodology is rather new and some open issues which deserve further study can be pointed out. |
17383cd4c534115fe1b942c1f3517a28 | 101 667 | 6.4.1 Localization | One of them is about the need for efficient and reliable methods and procedures for investigating the reasons and localization of possible incorrect behaviours. This is a critical point especially when the network under test is "very complex". The first step would be to identify which Operator generated the incorrect b... |
17383cd4c534115fe1b942c1f3517a28 | 101 667 | 6.4.2 Optimization | Another issue relates to balancing between detailed analyses and eavy development efforts and the need of avoiding duplicating efforts. For example, a network fault that emerged by using and End to End Test Suite could be investigated in detail by executing a corresponding Node-to-Node Test Suite (with equivalent Test ... |
17383cd4c534115fe1b942c1f3517a28 | 101 667 | 6.4.3 Costs and availability of NIT ETS on the market place | The number of NIT ETS available on commercial testing platforms (on the market place) is growing consistently every day but, due to their intrinsic complexity and to the reduced market, the prices of such products, when commercially available, are in general not cheap. ETSI ETSI TR 101 667 V1.1.2 (1999-07) 19 |
17383cd4c534115fe1b942c1f3517a28 | 101 667 | 6.5 Some results from the NIT methodology | One of the more prolific originators of NIT Test Suites is EURESCOM. In 1992 the EURESCOM P104 project on ISDN testing started introducing explicitly the concept of end-to-end testing, in which the tested object is not an implementation of a stack of protocols in a given system from a single vendor, but is the function... |
17383cd4c534115fe1b942c1f3517a28 | 101 667 | 7 Conclusions | In the present document, the general concepts of the NIT methodology have been described and a discussion of NIT when compared to the Conformance Testing has been developed. NIT provides a fast and simple method to test interconnected networks. NIT was first defined within EURESCOM to ensure that interconnected network... |

0ff16a1353d18c9835694e27515ee034 | 101 666 | 9 TTCN test suite structure | |
0ff16a1353d18c9835694e27515ee034 | 101 666 | 9.1 Introduction | TTCN allows a test suite to be hierarchically structured in accordance with ISO/IEC 9646-1, 8.1. The components of this structure are: a) Test Groups; b) Test Cases; c) Test Steps. A TTCN test suite may be completely flat (i.e., have no structure) in which case there are no Test Groups. TTCN allows the use of Test Step... |
0ff16a1353d18c9835694e27515ee034 | 101 666 | 9.2 Test Group References | TTCN supports a naming structure that shows a conceptual grouping of Test Cases. Test Groups can be nested. Test Cases can also be stand-alone (see ISO/IEC 9646-1, clause 8, figure 9). The Test Group References define the structure of the test suite. EXAMPLE 3: A Transport group reference: TRANSPORT/CLASS0/CONN_ESTAB/ |
0ff16a1353d18c9835694e27515ee034 | 101 666 | 9.3 Test Step Group References | Test steps may be explicitly identified in TTCN and used to structure Test Cases and other Test Steps. Alternatively Test Steps may be implicit within the behaviour description of a Test Case. Explicit Test Steps may be specified either - locally within a Test Case or Test Step behaviour description; or - globally with... |
0ff16a1353d18c9835694e27515ee034 | 101 666 | 9.4 Default Group References | Default behaviours (if any) are located in a Default Library. A Default Group Reference specifies the location of the Default in the Default Library, which may be hierarchically structured. The Default Library has no influence on the test suite structure itself. ETSI TR 101 666 V1.0.0 (1999-05) 29 EXAMPLE 5: Transport ... |
