review: Integrated Services in the Internet Architecture: an Overview
- What is the best way to
provide real time services over the internet? Is best effort transport reliable enough
to provide adequate services for time sensitive packets? How can we differentiate between packets
that must have a higher QoS, and what should the method of payment be?
- A standards proposal for a
method of providing quality of service over the current internet. An evaluation of how this improves upon
previous methods and why it was designed in this particular way.
- A. Traffic Control mechanisms actively supported:
Guaranteed Delay bounds. Because of the WFQ scheduling there always exists an upper bound for delay that can be assured. This is important for interactive
Link Sharing Allows multiple distinct shares to be
active on one link and then allocates additional space
as free bandwidth.
Predictive real-time service. Allows separation of traffic that has
different service objectives and leads to the optimization of both.
- Paper consists of 2
elements: An extended service model
(IS model) that provides the details of the added features of Integrated
services, and a reference implementation framework that defines the types
and properties of the different pieces of the IS model.
- Critique the main
System researchers and
builders should recognize that quality of service over the internet is a
must, even back in 94. As more
traffic needs to be real-time there must be a way of deciding who gets
priority and how it must be done.
This paper is rather broad, and although its ideas have not been
tested, it is bold in its attempts to create a service model without much
additional overhead. You must
realize that at this time, creating a 2nd internet for
real-time services was seen as an option, and with proposals such as this,
it was know that would not be necessary.
- Significance- 3
The article is more of an brainstorm of
proposals using the current implementations rather than an actual
discovery. The added functionality
and reasons behind it are justified, but too theoretical.
- Convincing- 2 Each of the implementations are well explained but
will be much harder to implement then to create in theory.
