Abstract

The OpenRouter project aims at the adoption of open source software for the development of an efficient and open architecture router/firewall device. The system being developed offers firewall/routing functionality that addresses the needs for low cost, high performance, open source based, user-friendly system for the SME and SOHO market. The OpenRouter system features LAN, WAN and wireless interfaces to meet the requirements of the SOHO environment. The system is being build using open source software on an embedded Linux platform, running on Intel StrongARM. For the scope of the project, off-the-self open source components will be used for the basic networking functionality and new modules will be developed for the integration, maintenance, operation, configuration and software upgrade subsystems. The project is part of the European Commission IST programme, under Key-action IV.3 (Research in & take-up of Open Source / Free Software).
CSEM contributions to the project are mainly related to the wireless access. The wireless access point functionality is being implemented reusing, whenever possible, open source code. The wireless standards supported are IEEE 802.11 Wireless LAN (WiFi) and Bluetooth. Existing drivers and protocol stacks for various IEEE 802.11 and Bluetooth hardware have been ported and debugged for the StrongARM target. For the IEEE 802.11 interface, as access point has been implemented, including all usual options: encryption, roaming and low power support. For the Bluetooth interface, the LAN access profile has been implemented. Depending of the configuration of the wireless interface desired by the user, various networking features of the Linux kernel have been exploited, such as bridging, network address translation (NAT), point-to-point protocol (PPP) or routing
