The explosive growth of data-traffic, for example due to the popularity of the Internet, poses important emerging network requirements on today’s telecommunication networks. This paper describes how core networks will evolve to Optical Transport Networks (OTNs), which are optimised for the transport of data-traffic, resulting in a IP-directly-over-OTN(More)
Due to the fast increase of Internet traffic and the enormous bandwidth potential of all-optical transport networks based on wavelength division multiplexing, an IP-over-WDM network scenario is likely to be widespread in future communication networks. At the same time, IP networks are becoming more and more mission-critical. Hence, it is of paramount(More)
Linux-based routers: +Availability on a wide variety of platforms; +Developed in an open and distributed way; +Meets the current requirements of modern operating systems; +Extensive and grooming set of networking features; -Functionalities bounded by CPU performance -Forwarding performance difficult to predict: PC (shared) busses interrupt overhead(More)
This paper presents how a working prototype of a VLAN (Virtual LAN) and GVRP (Generic VLAN Registration Protocol) aware Ethernet switch for Linux can be built using a “Writing code is good but integrating existing code is much better” approach. The paper is split into two parts. The first part describes the development of the signalling component of the(More)

This public part of D1.3 is the basis for an extended white paper describing the TEQUILA rationale for QoS delivery in IP networks. The document explains the TEQUILA approach, highlights the main innovative strenghts of the project and covers Service Management, Traffic Engineering and Monitoring and Measurement, i.e. the main systems under study within the(More)
In this paper we propose a new router architecture that combines both flexibility and performance. This router architecture aims at combining the best of two worlds: the commercial routers, which have a proven track for stability and performance but lack the flexibility of routers with open source operation system. The latter is particularly flexible(More)
