Multimedia Communications over Internet Protocol

Shifta Ansari, Kashif Nizam Khan, Jinat Rehana et al. · 2009

Currently two standards exist for signaling and control of voice over IP calls, namely ITU-T Recommendation H.323 and the IETF Session Initiation Protocol (SIP). Although there are a significant number of similarities between these two protocols, they behave significantly different when providing different higher level services. On one hand, SIP provides flexibility with broader scope, offering functions specifically designed to enable easy extensions of new technologies. On the other hand, H.323 stands still with more established standard providing better framework and interworking. This paper describes some noteworthy differences between them and presents some solutions to make these two giant players co-existing.

Internet Protocol for aeronautical communications

Max Ehammer, F. Bennison · 2013

Civil aviation business is currently experiencing the beginning of an operational change from voice based toward data based control mechanisms. This change shall be accompanied through a technological improvement that is in particular a change from an ISO/OSI toward a TCP/IP based network infrastructure. This paper presents outcomes of two independent investigations of utilizing the initial specification for the Aeronautical Telecommunication Network (ATN) using Internet Protocol Suite (IPS) standards and protocols via aeronautical data links. Thereby, both studies had one common objective, namely the validation of the ATN/IPS via aeronautical data links. One study was conducted by University of Salzburg through the evaluation of simulations, while the other study was conducted by the Swedish air navigation service provider LFV through flight trials based on real protocol implementations. Despite the difference of the evaluation scenarios the conclusions that can be drawn from both studies are similar.

FMEF computer-to-computer communications protocol

A.J. Grambihler, P.B. O'Callaghan · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 1982

This document describes the generalized Computer-to-Computer Communications Protocol (C3P). The protocol design facilitates communication between dissimilar computer systems. Computers can communicate using subsets, or full implementations of this protocol. This document does not address communications protocols within an integrated computer system. The protocol is based on the Eaton-Kenway Communications Protocol Document No. SE-051-76 which needs to be implemented for some of the equipment being supplied by Eaton-Kenway. The protocol has been expanded upon by Westinghouse Hanford Company (WHC) with the permission of Eaton-Kenway. WHC modifications have been made to facilitate segmentation of messages to be transmitted, and ease the implementation of multi-task, multi-computer communications. This document is intended to provide the reader with enough information to implement the basic protocol in hardware, software or a combination of both. The protocol described herein is designed to support communication over dedicated serial communications links in a noisy environment. The protocol will detect and cause retransmission of garbled or lost messages. The complete protocol supports transmission of messages in either direction independently and simultaneously, with routing to and from multiple tasks on multiple computers.

The Space Communications Protocol Standards Program

Hooke, Adrian J., Jeffries, Alan · NASA Technical Reports Server (NASA)

In the fall of 1992 NASA and the Department of Defense chartered a technical team to explore the possibility of developing a common set of space data communications standards for potential dual-use across the U.S. national space mission support infrastructure. The team focused on the data communications needs of those activities associated with on-lined control of civil and military aircraft. A two-pronged approach was adopted: a top-down survey of representative civil and military space data communications requirements was conducted; and a bottom-up analysis of available standard data communications protocols was performed. A striking intersection of civil and military space mission requirements emerged, and an equally striking consensus on the approach towards joint civil and military space protocol development was reached. The team concluded that wide segments of the U.S. civil and military space communities have common needs for: (1) an efficient file transfer protocol; (2) various flavors of underlying data transport service; (3) an optional data protection mechanism to assure end-to-end security of message exchange; and (4) an efficient internetworking protocol. These recommendations led to initiating a program to develop a suite of protocols based on these findings. This paper describes the current status of this program.

Optional Protocol on a Communications Procedure

Márta Benyusz · Central European Academic Publishing eBooks · 2024

The Optional Protocol to the Convention on the Rights of the Child on a communications procedure (hereinafter OPIC) was adopted on December 19, 2011, and entered into force on April 14, 2014. It opened the possibility for individual complaints to be brought to the Committee on the Rights of the Child (hereinafter CRC Committee or Committee) whenever domestic remedies were exhausted, in cases of the occurrence of an alleged violation to the provisions of the United Nations (UN) Convention on the Rights of the Child (CRC) or its two Optional Protocols, by state parties to any of these international instruments, as well as when for an unreasonably long time no step was taken by the given state to address the alleged violation. The main aim of the OPIC was to enhance children’s access to their rights, especially to effective remedy at an international level. The OPIC was also the last piece of the puzzle in the UN treaty body system, as its adoption led all UN treaty bodies to have the competence to receive individual communications procedures. Nevertheless, although the CRC itself is the most widely ratified human rights treaty and the other two Optional Protocols have a very wide acceptance, the OPIC has a low rate of signatory states and an even lower ratification rate.

Deriving protocol converters for communications gateways

Gregor von Bochmann · IEEE Transactions on Communications · 1990

Gateways are introduced for interworking between several, possibly heterogeneous, distributed computer systems. A gateway has to provide for the necessary adaptation between the communication protocols used in the interconnected networks. The adaptation problem is best handled by considering the communication services of the interconnected systems. Once the problem is solved at this level, the remaining problem of conversion between the incompatible communication protocols used in the different systems can be solved automatically, as demonstrated for the case of a simple example of data transmission service from a sender to a receiver process.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
