May 2 nd, 2001, page n° 4 The invisible network: an example
May 2 nd, 2001, page n° 5 Security Internet security seems to be a subject of interest for a rather small but highly technical audience Readily available hacking software/documentation makes it quite easy to launch Internet attacks The IETF security standardization activities do not sufficiently address end-to-end security We should give the highest priority to the definition and implementation of (simple & scalable) security processes/procedures (i.e. a security infrastructure) to prevent penetration of malicious code (Internet, Active Networks, …) abuse of networking and storage resources (NGN, CDN,...)
May 2 nd, 2001, page n° 6 Optical networks More users seem to have an inexhaustible appetite for more bandwidth Recent technology developments are rendering (all)-optical networks the dominant transport architecture of the future (long haul, metro, access, LAN? …..) MPLS (control plane) is the way to control both the IP layer and the optical layer (MP S) including protection, restoration and provisioning Research and standardization is required to make G-MPLS the common control plane architecture to provide unified control of packets/circuits/wavelengths and ports
May 2 nd, 2001, page n° 7 E2E QoS provisioning QoS and traffic theory has played a very minor role in the design of the current Internet The (a posteriori) introduction of QoS in IP networks has posed several key challenges with regard to the definition and standardization of scalable traffic management and QoS routing strategies in a multi-service/multi-access environment Understanding the relationship between traffic and performance is key to build networks capable of meeting end-to-end QoS requirements and to define (in standards) the most optimum techniques to deliver and guarantee QoS (service level specifications, performance monitoring, policy enforcement,...)
May 2 nd, 2001, page n° 8 Other topics of interest Migration / transition scenarios Interoperability Standardization
May 2 nd, 2001, page n° 9 Self-Organized, Infrastructureless networks Progress in technology and applications are triggering the emergence of new kinds of networks (e.g. ad hoc networks) The characteristics of these networks require specific solutions for a number of networking issues Medium and long term research/standards should focus on routing, mobility management, service availability IP addresses (topology-based address may not be optimal) security, transport layer performance (TCP), QoS for real-time services, capacity provisioning etc….
