QoS classification for mobile networks: international roaming case study
- Trang 356-360
We are interested in modeling the quality of service (QoS) parameters from end-to-end when using a mobile network. We know that the QoS is not an exact science. So, we list the parameters to be taken into account when one wants to describe the QoS applied to network interconnection, to a specific network or part of the network. We have also apply this classification to an international roaming app......

Mobile Internet navigation system
- Trang 325-328
This paper presents a mobile Internet navigation system (MINS) which can provide traffic-condition acquisition and monitoring convenience for mobile phone users by using the wireless application protocol (WAP) format. This system operates in two ways. Firstly, mobile phone users can access the network to request road traffic information from the database of the server. This feature is useful to a ......

Mathematical modeling, performance analysis and simulation of current Ethernet computer networks
- Trang 380-382
This work describes an object oriented software, to be portable among different types of computer platforms, able to perform the simulation of different components of Ethernet local and long distance area networks by using the TCP/IP protocol. It is also able to detect problems in projects and operation of communication networks through the separate or joint analysis of these elements. The functio......

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......

A location tracking algorithm for wireless ATM networks with mobile switches
- Trang 192-196
The mobile PNNI scheme for the location management in wireless ATM networks based on the PNNI routing protocol supports the mobility of terminals. However, this scheme is difficult to be directly applied to mobile switches in wireless ATM networks. This paper proposes a new location tracking algorithm to guarantee the mobility of terminals and switches in wireless ATM networks. Mobile switches and......

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......

Proposal and evaluation of ERICA switch algorithm as explicit rate mechanism in GFR backbones with ABR flow control
- Trang 152-156
The performance of a new guaranteed frame rate (GFR) service category implementation method is proposed and evaluated. This method implements GFR using an available bit rate (ABR) flow control mechanism, allocates virtual source/virtual destination (VS/VD) to edge switches, and uses explicit rate indication for congestion avoidance explicit rate (ERICA ER) marking mechanism at backbone switches. T......

A feasible distributed test system applied in routing protocol test
- Trang 172-176
It is believed that to test a distributed system, the test system itself must also be a distributed one. In our test of Internet routing protocols, this is confirmed again. With a centralized test system, the test ability is rather limited. We propose a distributed test system to perform effective test based on the grasp of the features and test requirements of the routing protocols. This test sys......

QoS control mechanism evaluation to design a reliable policy repository
- Trang 300-304
The Cooperative AppLIcation Framework (CAliF) QoS service is based on a QoS request administrator and uses a policy repository to parameterize the various elements of the network according to the application behavior by using various QoS control mechanisms. A policy is one or more rules that describe the actions that will occur when specific conditions exist. We present the results of QoS mechanis......

The fairness of TCP Vegas in networks with multiple congested gateways
- Trang 115-121
We investigate the performance of TCP Vegas in networks with multiple congested gateways. Our work focuses on the fairness between multiple-hop connections and cross traffic connections at each gateway. We find that TCP Vegas tends to be biased against multiple-hop connections. By analysis and computer simulations, we show that this bias is rooted in Vegas's RTT-based congestion avoidance mechanis......
