A greater number of customers are requiring that data communication networks be simulated before build-out of the networks occurs.  The uses of modeling and simulation include:

• Engineering network capacity and performance to ensure the network is interoperable with other networks that connect to it. 
• Testing the effects of adding applications to an existing network prior to installing the new applications on the production network. 
• Testing new architectures, algorithms and protocols for next generation data communications systems prior to committing the designs into software or hardware.
• Performance engineering against a variety of application traffic types (voice, video, data).
• Understanding the operation of protocols (IPV6, MPLS, WLAN, PNNI)
• Troubleshooting existing networks.

Accipiter Systems brings years of experience to network simulation using the OPNET network simulation tool suite for simulation of wired and wireless networks.   Past experience includes:

OPNET modeling and simulation of large scale MPLS Computer networks. 

This research analyzed three worst case, large scale MPLS simulation scenarios. 

OPNET modeling and simulation of a payload and protocol agnostic switch router. 

Models were developed for a high capacity, payload and protocol agnostic switch router node and then

simulated MPLS running on a network built from these switch router nodes.

Mobile Multi-Layered IPSec. 

Provided consulting to Pennsylvania State University to aid the use of the OPNET Wireless Module and in

the area of traffic generation.
