Tutorial: Quick and easy network service and packet processing using NetServ

Organizers

Jae Woo Lee, Columbia Univ.; Roberto Francescangeli, Univ. of Perugia

Time

Tues 3:30 - 5:30 pm

Description

NetServ is a programmable router architecture, designed for dynamically deploying in-network services. Using NetServ, GENI experimenters can write TCP/IP and packet processing application modules quickly in Java, and dynamically install them into any NetServ-enabled ProtoGENI or PlanetLab nodes. In this hands-on tutorial, you will learn the NetServ architecture, and develop a simple NetServ application module.

A step-by-step instruction is available here: GEC11NetServTutorialInstruction

Prerequisites:

Required:

• Basic understanding of GENI concepts (covered in the Introduction to GENI talk)
• Java programming experience

Helpful, but not required:

• Experience working with ProtoGENI (covered in an earlier tutorial: Introduction to GENI using Flack by Rob Ricci)

Please arrive with:

A laptop with VirtualBox (​http://www.virtualbox.org/) installed. If you are unable to bring one, you may partner with someone else.

Pre-work:

Required:

None.

Suggested background materials if you have time:

• 14-minute video of NetServ demo at GEC9 plenary session:

Results:

After completing this tutorial, you will:

• Understand NetServ architecture--for example, how various technologies such as Netfilter, JNI and OSGi work together to enable packet processing in Java.
• See how NetServ can shorten the development cycle of your experiments, and how it can create a gentler educational environment for your networking classroom.
• Know how to write a NetServ application module.
