RT Conference Proceedings T1 A practical approach to network-based processing A1 Larrabeiti López, David A1 Calderón Pastor, María Carmen A1 Azcorra Saloña, Arturo A1 Urueña Pascual, Manuel AB The usage of general-purpose processors externally attached to routers to play virtually the role of active coprocessors seems a safe and cost-effective approach to add active network capabilities to existing routers. This paper reviews this router-assistant way of making active nodes, addresses the benefits and limitations of this technique, and describes a new platform based on it using an enhanced commercial router. The features new to this type of architecture are transparency, IPv4 and IPv6 support, and full control over layer 3 and above. A practical experience with two applications for path characterization and a transport gateway managing multi-QoS is described.
