Internet Draft M3UA Conformance Test Plan Dec 2001
Abstract
This document presents the test specification for M3UA (MTP3 User
Adaptation) protocol (ver 10), which can be used to test M3UA
implementations for conformance to the protocol definition. 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.

Internet Draft M3UA Conformance Test Plan Dec 2001
1 Introduction
The M3UA is a protocol for the transport of any SS7 MTP3-User
signaling (e.g. ISUP and SCCP messages) over IP using the Stream
Control Transport Protocol (SCTP) or any other suitable transport
protocol. 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
