Design and performance evaluation of a Programmable Edge Node with x86 Multi-Core Processors and Network Processors

Current Capabilities

UMLPEN Architecture and Design ===

A design for PEN has been completed; see PEN Design

Integration of PEN into ProtoGENI Control Framework ===

The initial integration of PEN inth the ProtoGENI control framework has been completed; see Integration of PEN into ProtoGENI Control Framework

Usage of PEN in ProtoGENI ===

PEN is now avaialble for use within ProtoGENI; see Usage of PEN in ProtoGENI

This shows the arrangement for using PEN that was shown in a demo at GEC5:

Project Technical Documents

Virtualization Technologies: XEN and OpenVZ
In this project, we choose to use OpenVZ for its virtualization of network stacks and moderate isolation.
Network Processors: IXP2850 and Acceleration-cards
Network processors (NPs) are multicore multithreaded processors optimized for network packet processing.

Spiral 1 Connectivity

The earliest connectivity requirement will be towards the end of year 1. The PEN deployment will either be located in UML labs or within one of the GENI substrate infrastructure networks. This will be determined during the year. IP connectivity between the PEN node and the UML lab (if they are not colocated) will be required after deployment. Layer 2 virtual ethernet connections are not required. Updates on this deployment decision can be monitored through the milestone UMLPEN: Deployable PEN available.
