On informing TCP sender by the current value of NIT parameter
- Trang 375-379
Satellite systems are becoming deeply involved in the Internet. In this paper,
we propose some algorithms for the additional mechanism which must be
implemented in one of the network components in case the network uses the CANIT
(Congestion Avoidance with Normalised Interval of Time) algorithm instead of the
standard congestion avoidance of TCP (transmission control protocol). As we
mentioned in f...

Dynamic thresholds buffer management in a shared buffer packet switch
- Trang 401-405
In a shared buffer packet switch, proper buffer management schemes are needed to
improve the fairness of buffer usage among different output queues and the
overall packet loss probability. We propose a dynamic thresholds buffer
management scheme called partial sharing and partial partitioning (PSPP). The
PSPP scheme could be viewed as the combination of complete sharing (CS) and
complete partition...

Dynamic network clustering for scalable management of broadcast traffic in an ATM LAN
- Trang 273-277
A genetic algorithm (GA) for dynamic partitioning an ATM LANE (LAN Emulation)
network is presented. LANE proves to be one of the best solutions to provide
guaranteed quality of service (QoS) for mid-size campus or enterprise networks
with a little modification of legacy LAN facilities. However, there are few
researches on efficient LANE network operations to deal with scalability issues
arising fr...

Advantages of VoIP in the German research network
- Trang 56-60
With the rise of telephony over the Internet, many institutes are looking at
that new technology. Before it can be applied sensibly and meaningfully, many
questions must be answered. The first one is about the interoperability of the
end systems. It should be possible to change the vendor and implement new
devices without any problems in the existing VoIP infrastructure. These ideas
led to single ...

On fast computing bypass tunnel routes in MPLS-based local restoration
- Trang 234-238
We outline a mechanism for fast rerouting IP traffic around link failures using
MPLS bypass tunnels. As the main component of this mechanism we propose a
simplified single-pair incremental Dijkstra algorithm. We evaluate the algorithm
and restoration mechanism performance when used in regular and random network
topologies.

VAD techniques for real-time speech transmission on the Internet
- Trang 46-50
We discuss techniques for voice activity detection (VAD) for voice over Internet
Protocol (VoIP). VAD aids in reducing the bandwidth requirement of a voice
session, thereby using bandwidth efficiently. Such a scheme would be implemented
in the application layer. Thus the VAD is independent of the lower layers in the
network stack (see Flood, J.E., "Telecommunications Switching - Traffic and
Networ...

Ressource allocation in communication networks
- Trang 229-233
A key problem in the design of communication networks is the planning of
bandwidth allocation to communication demands. Shortest path routing is the
traditional answer to this problem. However, it is well known that this can lead
to poor network performances. We propose a new approach which proceeds in two
steps. In the first step, the corresponding relaxation problem of load sharing
routing is so...

QoS management for an enhanced VoIP platform using R-factor and network load estimation functionality
- Trang 305-314
This paper presents the QoS management for an enhanced VoIP platform based on
H.323/MGCP interworking. This enhanced VoIP platform bears a call
agent/gatekeeper that centrally controls one or more media gateways. The QoS
management is based on a software module that resides on the call agent,
terminates and processes the RTCP stream of each connection and extracts the
appropriate results. These re...

Applications of liquid crystal spatial light modulators in optical communications
- Trang 239-242
Advances in liquid crystal (LC) materials and VLSI technology have enabled the
development of multi-phase spatial light modulators (SLM) that can perform
high-resolution, dynamic optical beam positioning as well as temporal and
spatial beam shaping in the 1550 nm optical communication window. These
attractive features can effectively be used to achieve optical switching,
optical spectral equalizat...

FLORAX-flow-rate based hop by hop backpressure control for IEEE 802.3x
- Trang 202-207
The standard IEEE 802.3x is introduced to manage the XON/XOFF flow control
mechanism in full duplex gigabit Ethernet. In an IEEE 802.3x network, a
downstream station can send XOFF messages to upstream stations to stop them from
sending data until a specified time slot has passed or the downstream station
receives a XON message. The development of an efficient XON/XOFF flow control
mechanism is sti...
