Abstract:
A main driver of Future Internet applications and
services is Quality of Service (QoS). Current Internet
technologies provide no suitable QoS support for end-to-end
connections due to several drawbacks of IntServ and DiffServ.
In this article, we propose the “Forwarding on Gates” (FoG)
architecture, which answers the QoS questions by the help of a
new inter-network architecture. It applies its own new network
protocol, which was designed to handle IntServ and DiffServ in
an integrated way. FoG supports resource reservations for
QoS guarantees in IntServ scenarios and prioritized traffic in
DiffServ scenarios as well as a combination of both. As core
advantage, the QoS support of FoG works in a scalable way by
allowing a network to move QoS states and delegate decisions
about the QoS usage to the entities demanding for QoS. This
article describes the architecture, its network protocol, and
solutions for interoperability with current networks. The
evaluation includes theoretical descriptions of network
configurations for a use case not supported by IP. Moreover,
simulations show that the protocol overhead is comparable to
IPv6, although packets can select QoS explicitly. Measured
routing graph sizes for various setups show the flexibility of the FoG architecture.
