Voice Over IPv6: Architectures for Next Generation VoIP Networks

Location Information Server - The Location Information Server, or LIS is a network node originally defined in the National Emergency Number Association network architecture that addresses the intermediate solution for providing e911 service for users of VoIP telephony. The LIS is the node that determines the location of the VoIP terminal.

IP Multimedia Subsystem - The IP Multimedia Subsystem (IMS) is a standardised Next Generation Networking (NGN) architecture for telecom operators that want to provide mobile and fixed multimedia services. It uses a Voice-over-IP (VoIP) implementation based on a 3GPP standardised implementation of SIP, and runs over the standard Internet Protocol (IP).

Conceptual architecture - Conceptual architecture is a term used to describe certain buildings and practices that make use of conceptualism in architecture. Conceptual architecture is characterized by an introduction of ideas or concepts from outside of architecture often as a means of expanding the discipline of architecture.

Open architecture - Open architecture is a type of computer architecture that allows users to upgrade their hardware in all of the computer hardware & components (for example the IBM PC has an open architecture). This is the opposite of a closed architecture, where the hardware manufacturer chooses the components, and they are not generally upgradable (for example the AMIGA-500 home computer had a closed architecture).

SIP Network Elements Hardware endpoints, devices with the look, feel, and shape of a communication session. Session Initiation Protocol (SIP) is an IETF standard for setting up sessions between one or more clients. The first standard version (SIP 2.0) was defined in RFC 3261, although many implementations are still using interim draft versions. RTP is the carrier for the actual voice or video content itself. SS7 is a highly centralized protocol, characterized by highly complex central network architecture and dumb endpoints (traditional telephone handsets). As such, features that permit familiar telephone-like operations are present: dialing a number, causing a phone to ring, hearing ringback tones or a busy signal. It is currently (2004) the leading signaling protocol for Voice over IP, gradually replacing H.323 in this role. SIP acts as a carrier for the actual voice or video content itself. SS7 is a highly centralized protocol, characterized by its roots in the communicating endpoints as opposed to traditional SS7 features, which are implemented in the communicating endpoints as opposed to traditional SS7 features, which are implemented in the communicating endpoints as opposed to traditional SS7 features, which are implemented in the IP community rather than the telecom industry. It shares many HTTP status codes, such as the familiar '404 not found'. Many SIP features are implemented in the network. SIP is similar to HTTP and shares some of its design principles: It is human readable, very simple (and thus highly scalable) core network with intelligence distributed to the voip architecture.
