A typical data transaction takes the form of a packet conversation, where the client identifies itself to a remote
host and submits some request for processing on behalf of a user. The host, after assuring the identities and
authorization of the client device and user, performs the request and communicates the result. In the case
of "short" transactions considered here, the result is a simple confirmation of the request to exchange funds,
or an account balance.
The reference path and reference transaction (illustrating a transaction with eight round-trip exchanges) are
described in the figures below.

Supplement 9 to the ITU-T E.800-series Recommendations “Guidelines on regulatory aspects of QoS” focuses
on end-to-end QoS as perceived by the user when using modern mobile and broadband services. The intent
here is to assist regulators or administrations who need to achieve desired levels of QoS for one or more
information and communications technology (ICT) services under their jurisdiction.

Recommendation ITU-T E.803 “Quality of service parameters for supporting service aspects” lists 88 generic
parameters over the product life cycle of ICT services which will enable a regulator, stakeholder or any interested
party to select a pertinent number of parameters about the Service Provider (SP) that provide performance
data. Performance data on the non-utilization stages of services, in addition to the service specific performance
usually dealing with in-use performance, are necessary to enable customers to choose a service provider (SP)
most suited to meet their specific quality of service (QoS) requirements.

QoS performance on non-utilization stages can benefit customers, regulators, stakeholders and service
providers (SPs) to monitor performance levels for the benefit of the customers and ICT industry. The essential
information to be obtained for measurement and reporting of performance levels is illustrated on a selection
of parameters. Guidance on presentation of performance results is also provided. Service providers reporting
of delivered performance to a recommended procedure will enable comparability among providers.
