Firewalls

The Firewalls and Internet Security seminar defines three basic types of firewalls: packet filters, circuit level gateways, and application gateways. Of course there are also hybrid firewalls, which can be combinations of all three. Packet filter gateways are usually comprised of a series of simple checks based on the source and destination IP address and ports. They are very simple to the user since it will probably not even realize that the checks are taking place (unless of course it w ....etc

The Wireless Application Protocol Forum is an industry group dedicated to the goal of enabling sophisticated telephony and information services on handheld wireless devices. These devices include mobile telephones, pagers, personal digital assistants (PDAs) and other wireless terminals. Recognizing the value and utility of the World Wide Web architecture, the WAP forum has chosen to align its technology closely with the Internet and the Web. The WAP specification extends and leverages existing technologies, such as IP, HTTP, XML, S ....etc

Using an ordinary phone for most people is a common daily occurrence as is listening to your favorite CD containing the digitally recorded music. It is only a small extension to these technologies in having your voice transmitted in data packets. The transmission of voice in the phone network was done originally using an analog signal but this has been replaced in much of the world by digital networks. Although many of our phones are still analog, the network that carries that voice has become digital.

In todays phone networks, t ....etc

ABSTRACT
Increasingly, network applications must communicate with counterparts across disparate networking environments characterized by significantly different sets of physical and operational constraints; wide variations in transmission latency are particularly troublesome. The proposed Interplanetary Internet (IPN), which must encompass both terrestrial and interplanetary links, is an extreme case. An architecture based on a protocol that can operate successfully and reliably in multiple disparate envi ....etc

Access gateways

A gateway is a network element that acts as an entrance point to another network. An access gateway is a gateway between the telephony network and other networks, such as the Internet. Access mediation supports the arbitration of call control and signaling between individual networks, resources, users, and services. Access mediation is the next evolutionary step for the advanced intelligent network (AIN). With the growing importance of the Internet, access gateways are a critical co ....etc

1). Introduction:
This document explains about VoIP systems. Recent happenings like Internet diffusion at low cost, new integration of dedicated voice compression processors have changed common user requirements allowing VoIP standards to diffuse. This how to tries to define some basic lines of VoIP architecture.
What is VoIP?
VoIP stands for ' Vâ„¢oice Ëœoâ„¢ver ËœIâ„¢nternet ËœPâ„¢rotocol. As the term says VoIP tries to let go voice (mainly human) through IP packets and, in d ....etc

ABSTRACT
The H.323 standard provides a foundation for audio, video, and data communications across IP-based networks, including the Internet. By complying to H.323, multimedia products and applications from multiple vendors can interoperate, allowing users to communicate without concern for compatibility. H.323 is an umbrella recommendation from the International Telecommunications Union (ITU) that sets standards for multimedia communications over Local Area Networks (LANs) that do not provide a guaranteed Quality ....etc

Abstract

WAP bridges the gap between the wireless mobile world and the internet. The Wireless Application Protocol (WAP) , is a collection of protocols and transport layers which allow mobile and portable communication devices such as mobile phones and Personal Digital Assistants (PDAâ„¢s), to receive information over the airwaves such as personal computers users obtain information over the internet. . WAP is simply a protocol- a standardized way that a mobile phone talks to a server installed in the mobile ....etc
