Internet Draft SUA Conformance Test Plan [Page 2]
Abstract
The SUA is a protocol for the transport of any SS7 SCCP user
Signaling (e.g. TCAP, RANAP or RNSAP messages) over IP
Between two signaling endpoints. This protocol can also support
Transport of SCCP-user messages between two endpoints wholly
Contained within an IP network. Depending upon the upper layer
Protocol supported, the SUA will need to support SCCP
Connectionless service, SCCP connect-oriented service or
Both services.

Internet Draft SUA Conformance Test Plan [Page 3]
1. Introduction
1.1 Scope
There is on-going integration of SCN networks and IP networks.
Network service providers are designing all IP architectures that
include support for SS7 and SS7-like signaling protocols. IP
provides an effective way to transport user data and for operators
to expand their networks and build new services. In these networks,
there may be some need for interworking between the SS7 and IP
domains.
This document details the Conformance of the SUA( SCCP User Adaptation
Layer) Protocol as per <draft-ietf-sigtran-sua-08.txt>
1.2 Terms Used
Signaling Gateway (SG) - Network element that terminates SCN
Signaling and transports SCCP-User signaling over IP to an IP
Signaling endpoint. A Signaling Gateway could be modeled as one
Or more Signaling Gateway Processes, which are located at the
Border of the SS7 and IP networks. 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.
Application Server (AS) - A logical entity serving a specific
Routing Key. An example of an Application Server is a virtual IP
Database element handling all requests for an SCCP-user. The AS
Contains a set of one or more unique Application Server Processes,
Of which one or more is normally actively processing traffic.
Application Server Process (ASP) - An Application Server Process
Serves as an active or backup process of an Application Server
(e.g., part of a distributed signaling node or database element).
Examples of ASPs are MGCs, IP SCPs, or IP-based HLRs. An ASP
Contains an SCTP end-point and may be configured to process traffic
Within more than one Application Server.
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 SUA in a peer-to-peer fashion. Conceptually, an IPSP does
Not use the services of a Signaling Gateway.
Signaling Gateway Process (SGP) - A process instance of a
Signaling Gateway. It serves as an active, load-sharing or
Broadcast process of a Signaling Gateway.
diaggarwal(editor) [Page 3]
Internet Draft SUA Conformance Test Plan [Page 4]
Signaling Process - A process instance that uses SUA to communicate
With other signaling process. An ASP, a SGP and an IPSP are all
Signaling processes.
Association - An association refers to an SCTP association. The
Association provides the transport for the delivery of SCCP-User
Protocol data units and SUA layer peer messages.
Routing Key - The Routing Key describes a set of SS7 parameters
And/or parameter-ranges that uniquely defines the range of
Signaling traffic configured to be handled by a particular
Application Server. An example would be where a Routing Key consists
Of a particular SS7 SCCP SSN plus an identifier to uniquely mark the
Network that the SSN belongs to, for which all traffic would be
Directed to a particular Application Server. Routing Keys are
Mutually exclusive in the sense that a received SS7 signaling
Message cannot be directed to more than one Routing Key. Routing
Keys can be provisioned, for example, by a MIB or registered using
SUA's dynamic registration procedures.
Routing Context - An Application Server Process may be configured to
Process traffic within more than one Application Server. In this
Case, the Routing Context parameter is exchanged between the SGP and
The ASP (or between two ASPs), identifying the relevant Application
Server. From the perspective of an SGP/ASP, the Routing Context
Uniquely identifies the range of traffic associated with a
Particular Application Server, which the ASP is configured to
Receive. There is a 1:1 relationship between a Routing Context values
And a Routing Key within an AS. Therefore the Routing Context can
Be viewed as an index into an AS Table containing the AS Routing
Keys. The Routing Context also uniquely identifies an SS7 entity
(Point code) into a SS7 network, as presented by the SGP.
Address Mapping Function (AMF) - The AMF is an implementation
Dependent function that is responsible for resolving the address
Presented in the incoming SCCP/SUA message to correct SCTP
Association for the desired endpoint. The AMF MAY use routing
Context / rouging key information as selection criteria for the
Appropriate SCTP association.
Fail-over - The capability to re-route signaling 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.
Fail-over may apply upon the return to service of a previously
Unavailable Application Server Process.
Network Byte Order - Most significant byte first, a.k.a. Big Endian.
diaggarwal(editor) [Page 4]
Internet Draft SUA Conformance Test Plan [Page 5]
Layer Management - Layer Management is a nodal function that handles
The inputs and outputs between the SUA layer and a local management
Entity.
Host - The computing platform that the SGP or ASP process is running
On.
Stream - A stream refers to an SCTP stream; a uni-directional
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 un-ordered
Delivery service.
Transport address - an address that serves as a source or
Destination for the unreliable packet transport service used by
SCTP. In IP networks, a transport address is defined by the
Combination of an IP address and an SCTP port number. Note, only
One SCTP port may be defined for each endpoint, but each SCTP
Endpoint may have multiple IP addresses.

2 General Principles of SUA 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.
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 and I); 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: Routing Context and Routing Key has been used inter exchangably.
In case of message it is Routing Context and in the test configuration
It is Routing Key.
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.
