Abstract:
Currently, the multiprotocol label switching (MPLS) standard is extremely prevalent. By exploiting the features provided by MPLS technology, a range of services, including IP telephony, have enhanced their overall performance. However, due to the size of the packet header, the IP telephony service consumes a significant portion of the MPLS network's available bandwidth. For instance, in IP telephony over MPLS networks, the packet header might account for as much as 80% of lost time and bandwidth. Designers working on IP telephony are making substantial efforts to address this issue. This study

Abstract:
Telecommunication networks and the Internet are growing together. Peer-to-Peer (P2P) services which are originally offered by network providers, like telephony and messaging, are provided through VoIP and Instant Messaging (IM) by Internet service providers, too. The IP Multimedia Subsystem (IMS) is the answer of the telecommunication industry to this trend and aims at providing Internet P2P and multimedia services controlled by the network operators. The IMS provides mobility and session management as well as message routing, security, and billing.

Abstract:
Over the recent years enormous changes in the telecommunication services, techniques, regulations and markets have taken place. However, even with many new exciting services the telephony service is still popular. This paper provides empirical traffic data and observations of telephony traffic patterns in mobile and IP telephony. They are presented and compared with old telephony patterns from Public Switched Telephone Networks (PSTN). The question is whether the characterization of telephony traffic should be reconsidered because new technology and markets might have changed the service and u

Abstract:
Telephony over IP (ToIP) is a cost-saving communication technology based on voice over IP (VoIP) that enables enterprises to reduce communication fees. However, ToIP faces many security threats due to its IP-based nature. This work aims to improve ToIP security using cryptography and blockchain technology. The authors propose a secure approach to user registration, authentication, communication session establishment, and communication data storage. The proposed solution leverages blockchain technology to ensure the integrity, confidentiality, and availability of communication data. By implemen

Abstract:
IP networks only offer best-effort service to all kinds of traffic. This means that IP tries to deliver each packet as quickly as possible, but makes no service guarantees. However, as the diversity of applications increase, this simple model with no service guarantees cannot satisfy all of them. For example, novel interactive applications such as Internet telephony, video conferencing, or networked games expect some performance guarantees to operate right. The growing importance of these recent applications with stringent constraints behooves network service providers to differentiate among v

The Telecoms market is demanding more services which involve an increased mobile accessibility to the Internet, real time video transmission, real time games, Voice over IP (VOIP), and business critical transactions such as billing transactions and banking services. Meeting these challenges requires the mobile operators to change the way they design their telephony and messaging systems. As the mobile market moves to become more service centric, rather than technology centric, Quality of Service (QoS) has grown to become imperative, since in the Telecoms innovative services are very often shor
