the operation of all these components. Henceforth, the NMSs are not considered
part of the testbed because they constitute the WINMAN management system
that is the subject of the evaluation.
This chapter is structured in five sections. In Section 10.2, we present the
functional and high-level requirements to be fulfilled. These requirements apply
to four different areas—requirements on testbed management systems, requirements
on the validations tools that will be required to deal with both IP and
WDM, and finally the requirements of both types of transport network infrastructure.
Section 10.3 describes the testbed itself, based on the final configuration
adopted by the IP and WDM parts, as well as the integration mechanism
used to bring the IP over the WDM. Finally, Section 10.4 outlines the implementation
of the adaptation required to interconnect the available EMSs to the
WINMAN NMSs. The two remaining sections are this introduction and the
summary ending the chapter.
10.2 Testbed Requirements
The testbed requirements are classified according to the different components
that will play a role in the validation process. These are the management equipment,
the testing and verification tools, and the involved transport network
infrastructures. Also, we remind the reader that the term NMS is used in the
context of this chapter to refer to the NMS to be tested.
10.2.1 Requirements on the Management Platforms
The general characteristics of the management platforms that the testbed must
supply are divided into high-level requirements and functional requirements as
follows.
10.2.1.1 High-Level Requirements
High-level requirements are intended to make possible the basic interaction
between the NMSs and the network they manage. One fundamental characteristic
of the testbed is that it must be connectable to the NMSs. This connection
will be performed through the southbound interface of the NMSs under test.
For instance, WINMAN defines the interfaces with the IP and WDM EMSs,
and the testbed shall be adapted to the WINMAN IP-NMS and WDM-NMS
public interfaces. The same principles would apply for other solutions that were
different from WINMAN.
The EMS testbed platforms shall apply to the network elements the operations
activated by the NMSs. They shall also forward to the NMSs information
