The invisible network: an example

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, ...)

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 (MPlS) 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

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, ...)

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,
 IP
mobility management, service availability
addresses (topology-based address may not be optimal)
 security,
transport layer performance (TCP), QoS for real-time
services, capacity provisioning etc….
