The list of test is exhaustive and covers almost all the categories of test. This draft can also be used in conjunction with M3UA specification by implementers of protocol as implementers guide, as the pictorial representation of various scenarios help easy understanding of the protocol. Next revision of the draft will cover the additions done to the protocol revision and any subsequent RFC published by IETF. Table of Contents 1.

This protocol would be used between a Signaling Gateway (SG) and an Application Service Provider (ASP) (e.g. Media Gateway Controller - MGC) or IP-resident Database. 1.1 Terms Used Application Server (AS) - A logical entity serving a specific Routing Key. An example of an Application Server is a virtual switch element handling all call processing for a unique range of PSTN trunks, identified by an SS7 SIO/DPC/OPC/CIC_range. Another example is a virtual database element, handling all HLR transactions for a particular SS7 DPC/OPC/SCCP_SSN combination. The AS contains a set of one or more unique Application Server Processes, of which one or more is normally actively processing traffic. Note that there is a 1:1 relationship between an AS and a Routing Key. Application Server Process (ASP) - A process instance of an Application Server. An Application Server Process serves as an active or backup process of an Application Server (e.g., part of a distributed virtual switch or database). Examples of ASPs are processes (or process instances) of MGCs, IP SCPs or IP HLRs. An ASP contains an SCTP endpoint and may be configured to process signalling traffic within more than one Application Server. Association - An association refers to an SCTP association. The association provides the transport for the delivery of MTP3-User protocol data units and M3UA adaptation layer peer messages. IP Server Process (IPSP) - A process instance of an IP-based application. An IPSP is essentially the same as an ASP, except that it uses M3UA in a point-to-point fashion. Conceptually, an IPSP does not use the services of a Signalling Gateway node. Failover - The capability to reroute signalling traffic as required to an alternate Application Server Process, or group of ASPs, within an Application Server in the event of failure or unavailability of a currently used Application Server Process. Failover also applies upon the return to service of a previously unavailable Application Server Process. Anshoo Sharma, HSS [Page 3] Internet Draft M3UA Conformance Test Plan Dec 2001 Host - The computing platform that the process (SGP, ASP or IPSP) is running on. Layer Management - Layer Management is a nodal function that handles the inputs and outputs between the M3UA layer and a local management entity. Linkset - A number of signalling links that directly interconnect two signalling points, which are used as a module. MTP - The Message Transfer Part of the SS7 protocol. MTP3 - MTP Level 3, the signalling network layer of SS7 MTP3-User - Any protocol normally using the services of the SS7 MTP3 (e.g., ISUP, SCCP, TUP, etc.). Network Appearance - The Network Appearance is a M3UA local reference shared by SG and AS (typically an integer) that together with an Signaling Point Code uniquely identifies an SS7 node by indicating the specific SS7 network it belongs to. It can be used to distinguish between signalling traffic associated with different networks being sent between the SG and the ASP over a common SCTP association. An example scenario is where an SG appears as an element in multiple separate national SS7 networks and the same Signaling Point Code value may be reused in different networks. Network Byte Order: Most significant byte first, a.k.a. Big Endian. Routing Key (RK): A Routing Key describes a set of SS7 parameters and parameter values that uniquely define the range of signalling traffic to be handled by a particular Application Server. Parameters within the Routing Key cannot extend across more than a single Signalling Point Management Cluster. Routing Context - A value that uniquely identifies a Routing Key (RK). Routing Context values are either configured using a configuration management interface, or by using the routing key management procedures defined in this document. Signalling Gateway Process (SGP) - A process instance of a Signalling Gateway. It serves as an active, backup, loadsharing or broadcast process of a Signalling Gateway. Anshoo Sharma, HSS [Page 4] Internet Draft M3UA Conformance Test Plan Dec 2001 Signalling Gateway - An SG is a signaling agent that receives/sends SCN native signaling at the edge of the IP network [1]. An SG appears to the SS7 network as an SS7 Signalling Point. An SG contains a set of one or more unique Signalling Gateway Processes, of which one or more is normally actively processing traffic. Where an SG contains more than one SGP, the SG is a logical entity and the contained SGPs are assumed to be coordinated into a single management view to the SS7 network and to the supported Application Servers. Signalling Process - A process instance that uses M3UA to communicate with other signalling processes. An ASP, an SGP and an IPSP are all signalling processes. Signalling Point Management Cluster (SPMC) - The complete set of Application Servers represented to the SS7 network under a single MTP entity (Signalling Point) in one specific Network Appearance. SPMCs are used to aggregate the availability, congestion, and user part status of an MTP entity (Signalling Point) that is distributed in the IP domain, for the purpose of supporting MTP3 management procedures towards the SS7 network. In some cases, the SG itself may also be a member of the SPMC. In this case, the SG availability /congestion /User_Part status should also be taken into account when considering any supporting MTP3 management actions. Stream - A stream refers to an SCTP stream; a unidirectional logical channel established from one SCTP endpoint to another associated SCTP endpoint, within which all user messages are delivered in-sequence except for those submitted to the unordered delivery service. ASPSM, ASPTM, SSNM - ASP State Maintenance Messages, ASP Traffic Maintenance Messages, Signalling System Network Management Messages. 2 General Principles of M3UA Tests These tests aim to verify a given implementation of a protocol in accordance with the relevant draft. The specification is independent of a given implementation and does not generally imply any modification of the endpoint under test. However, it is recognized that certain tests require capabilities of the system that are not explicitly defined in the draft, and these capabilities may not be present in all implementations. As a consequence, certain tests may not be possible in all implementations. Anshoo Sharma, HSS [Page 5] Internet Draft M3UA Conformance Test Plan Dec 2001 2.1 Presentation of test descriptions Each test description includes the environment in which the point under test must be inserted in order to pass the test. Nine test configurations are defined (named A, B, C, D, E, F, G, H, I and J); they are presented in clause 3. Each test is precisely described. Nevertheless, some events not directly concerning the point under test, or without direct link with the test nature, are not explicitly described. In order to preserve the test description implementation independence, certain flexibility has been left in the test descriptions. This is particularly the case when it is necessary to terminate the SCTP association (where it is only mentioned "Terminate" with no more precision). The operator will choose according to the implementation particularities and the events expected in the test description, the appropriate Termination means (MML- Man machine Language, provoked failure, etc.). 2.1.1 Pre Test Condition Before starting the test we need to get the setup into a condition from where test can be started. These conditions are specified in Pre-Test condition in each test. Note: Where NIF has been written, it means that NIF+SM. In some implementation these may be two entities and in some, they may be implemented in single entity. 3 Test Configurations: The set of tests described in this Recommendation assumes that the point under test is inserted in a test environment called "test configuration". 3.1 Presentation of test configurations: There are different configurations for testing the M3UA protocol. These configurations and hence test cases have been divided on the basis of M3UA at SG and M3UA at AS. 3.2 Configuration for testing the M3UA at SGP: 3.2.1 Configuration A: This simple configuration is used for all the procedures of tests concerning only one AS.
