A VoIP scenario where SIP user agents are in the same domain and served by a shared proxy server.

A VoIP scenario where SIP network elements are excluded, meaning calls happen directly between users.

Internet Protocol Television, delivering multimedia (TV, Video, Audio) over IP networks, ensuring QoS and QoE.

Three architectures for IPTV service delivery: Non-NGN, NGN-based non-IMS and NGN IMS-based .

Delivery of IPTV content simultaneously to multiple destinations from a single source.

Guarantees consistent performance of network resources, like bandwidth and latency.

Measures the user's perception of the quality of a network experience.

Next Generation Network: A network infrastructure for converged voice, video, and data services.

ITU-T defines four models for delivering IPTV content via multicast: Network Multicast, Cluster, P2P, and Hybrid (Cluster+P2P).

IPTV delivery method where content is streamed individually to each user.

Unicast IPTV delivery has two scenarios: non-roaming and NGN roaming.

Web services, based on HTTP/TCP/IP, are crucial in best-effort internet and integrated into NGN using Application-Network Interface (ANI).

Web services are registered with a web registry using WSDL (Web Services Description Language).

Integration of fixed and mobile telecoms technologies.

FMC is not new, rooted in technologies like DECT, UMA, and GAN from the 1990s.

The NGN interface for web service providers.

The Public Switched Telephone Network (PSTN) uses a constant bit rate of 64 kbit/s in each direction for digital telephony. This is achieved using the ITU-T G.711 codec (Pulse Code Modulation).

VoIP (Voice over Internet Protocol) experiences higher packet delays compared to PSTN due to the use of IP networks. This is caused by statistical multiplexing and the additional processing time involved in routing IP packets.

VoIP is susceptible to jitter, or variations in packet delay. This occurs because of statistical multiplexing and packet scheduling within the IP network, leading to inconsistent delays for VoIP packets.

The PSTN uses specialized intelligent exchanges and an overlay signaling network to manage calls. These exchanges handle routing and other signaling processes.

VoIP systems typically utilize intelligent terminals like computers and simpler network nodes like routers. This allows for flexibility and cost-effectiveness.

A major benefit of VoIP is its ability to converge different services, like telephony, TV, and data, onto a single Internet-based platform. This reduces operational costs and simplifies infrastructure.

VoIP offers greater service flexibility compared to PSTN, allowing for more diverse features and customization options. This versatility makes VoIP more adaptable to evolving user needs.

VoIP aims to achieve the same level of reliability as PSTN with a target availability of 99.999% throughout the year, ensuring consistent service delivery.
