چکیده (انگلیسی):

Recent events have shown that content delivery networks
as well as Broadband Providers are failing to provide a continuous
service, especially on live video stream transmissions for numerous
customers. This study aims to present a Methodology to
uninterruptedly measure uplink-downlink of a given IP connection.
Based on an open-source assemblage of development and data storage
platforms it was programmed a software that automatically attends the
proposed assessment. The significance of availability is effusively
addressed on this article, since it is the first requirement regarding
quality of service in any engineered communication. The proposed
method relates to the fact that for a video and/or audio web stream to
successfully occur, a connection with each end-user device needs to
be sustained the entire time, establishing a complex two-way
communication. Meanwhile, traditional cable and satellite broadcasts
are less stressful one-way connections, demanding only that the enduser
device to be placed within range of a radio signal. Given this
scenario and adding the substantial demand increase for high quality
media content from the internet, emerges an essential need to control
the service delivered by CDNs and Broadband Providers. The
developed software also creates a reasonable billing mechanism,
which can function as a new technical milestone on contracts and/or
Service Level Agreements. This tool also imposes a key function to
the user’s role, once it requires a setup of all seeked tests to be
manually inserted, which might limit it for some routines.
