TCN TimeAnalyzer TimeAnalyzer in real-time networks

Summary

TCN TimeAnalyzer™ is a unique application providing worst-case (and best-case) timing predictions of a switched Ethernet network by analyzing a model of the network.

A central part in TCN TimeAnalyzer™ is the computational engine that implements a set of formulas that allows the computation of upper bounds on frame latency, jitter and maximum frame buffer space required in each switch. The formulas are a result of applying real-time scheduling analysis to packet forwarding in a packet switched Ethernet network. These formulas constitute a computational model which allows the prediction of how the limited speed of physical network devices and contention among different packets for the same network resources gives rise to latency, jitter, etc. for a specific packet forwarded between two nodes in the network. The computational analysis engine will incorporate models of every component used in the network and also every other entity that compete for the same network resources as the packet under observation.

TCN TimeAnalyzer™ builds simulation models of how different configuration parameters and packet scheduling mechanisms of certain switches will affect worst case traffic situations.

A feasibility study shall be developed verifying the technological/practical as well as economic viability of the innovation. Activities will focus on innovation activities such as demonstration, testing, prototyping, piloting, scaling-up, design aiming to bring the product to industrial readiness and maturity for market introduction. It will also include some research to further develop the computational engine.

Original description

TCN TimeAnalyzer™ is a unique application providing worst-case (and best-case) timing predictions of a switched Ethernet
network by analyzing a model of the network.

A central part in TCN TimeAnalyzer™ is the computational engine that implements a set of formulas that allows the
computation of upper bounds on frame latency, jitter and maximum frame buffer space required in each switch. The formulas
are a result of applying real-time scheduling analysis to packet forwarding in a packet switched Ethernet network. These
formulas constitute a computational model which allows the prediction of how the limited speed of physical network devices
and contention among different packets for the same network resources gives rise to latency, jitter, etc. for a specific packet
forwarded between two nodes in the network. The computational analysis engine will incorporate models of every
component used in the network and also every other entity that compete for the same network resources as the packet
under observation.

TCN TimeAnalyzer™ builds simulation models of how different configuration parameters and packet scheduling
mechanisms of certain switches will affect worst case traffic situations.

A feasibility study shall be developed verifying the technological/practical as well as economic viability of the innovation.
Activities will focus on innovation activities such as demonstration, testing, prototyping, piloting, scaling-up, design aiming to
bring the product to industrial readiness and maturity for market introduction. It will also include some research to further
develop the computational engine.
