Abstract

Dedicated network impairment devices are an accepted method to emulate network latency and loss, but are expensive and not available to most users. This project will compare the performance of a dedicated network impairment device with that of performing network emulation within the Linux kernel to simulate the parameters when utilizing TCP.

Intellectual Merit

This testing will be used as validation of WAN impairment of TCP and LNET over a single 100 gigabit Ethernet circuit being conducted in Germany through a partnership with the Technische Universität Dresden.

Broader Impacts

Results will be widely disseminated through a joint paper with Technische Universität Dresden and presented to Internet2 members in April.

Resource Requirements

Hardware System
  • Network Impairment Device
 
Use of FutureGrid

For this project the FutureGrid Spirent Network Impairment Device will need to be utilized and relocated by IU GRNOC staff to Bloomington, IN for a period of 2-4 weeks beginning March 7, 2011.

Scale of Use

We will only be using the network impairment device connected to dedicated servers and storage in the IU Bloomington data center.
