• Resource requirements of first installation
• Resource requirements of operations
In case of separated measurements, network domains usually stay separated from each other.
Management stations are expected to exchange information with each other. Reports are generated
and distributed on a provider-specific basis. When Web-based solutions are in use, reports by different
providers may be prepared separately, and presented together. The authorized client may access infor-
mation and reports on the Web server.
In case of collaborative measurements, management stations are eligible to mutually access measure-
ment data. This should be negotiated between the service providers on either on a permanent basis or in
cases of outages. Management stations exchange information with each other and offer mutual backup
to each other. Reports are generated together and are usually distributed via the Web. The maintenance
of datamarts or data warehouses is supported as a joint venture. Measurements are grouped as follows:
• Active measurements against measurement point
• Active measurements against server
• Passive measurements over TCP measurement point
• Passive measurement over mirror port
• Passive measurements over application measurement point
Additional measurement options can be defined depending on the tools in use. The network tech-
nology for the new infrastructure is very complex; it would be no surprise to select specific products
to address specific needs. To go to best-of-breed is correct, but as a result, integration of many good,
specific products must be addressed.
4.5.3.3.8 Defining the Depth of Reporting
It is assumed that basic data are collected and processed using unified guidelines. The minimal require-
ment is that eligible clients can access raw data, preprocessed data, or fully processed data on a Web
