About: Pseudowire

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In computer networking and telecommunications, a pseudowire (or pseudo-wire) is an emulation of a point-to-point connection over a packet-switched network (PSN). The pseudowire emulates the operation of a "transparent wire" carrying the service, but it is realized that this emulation will rarely be perfect. The service being carried over the "wire" may be Asynchronous Transfer Mode (ATM), Frame Relay, Ethernet or time-division multiplexing (TDM) while the packet network may be Multi-protocol Label Switching (MPLS), Internet Protocol (IPv4 or IPv6), or Layer 2 Tunneling Protocol Version 3 (L2TPv3).

  • In computer networking and telecommunications, a pseudowire (or pseudo-wire) is an emulation of a point-to-point connection over a packet-switched network (PSN). The pseudowire emulates the operation of a "transparent wire" carrying the service, but it is realized that this emulation will rarely be perfect. The service being carried over the "wire" may be Asynchronous Transfer Mode (ATM), Frame Relay, Ethernet or time-division multiplexing (TDM) while the packet network may be Multi-protocol Label Switching (MPLS), Internet Protocol (IPv4 or IPv6), or Layer 2 Tunneling Protocol Version 3 (L2TPv3). The first pseudowire specifications were the for ATM pseudowires, and the TDMoIP draft for transport of E1/T1 over IP. In 2001, the Internet Engineering Task Force (IETF) set up the PWE3 working group, which was chartered to develop an architecture for service provider edge-to-edge pseudowires, and service-specific documents detailing the encapsulation techniques. Other standardization forums, including the International Telecommunication Union (ITU) and the MFA Forum, are also active in producing standards and implementation agreements for pseudowires. Starting from 2006, telecom operators like BellSouth, Supercomm, AT&T, and Verizon began to invest more into pseudowire technology, pointing out its advantages to Ethernet in particular. Pseudowires tie services together across multiple transport technologies, including Ethernet over SONET, WDM, GPON, DSL, and WiMax. Over the next decade, the technology became mainstream. In 2017 Cisco published a comprehensive document explaining the concept, troubleshooting, and configuration details for all Cisco equipment pieces, which supported pseudowire. Today, the service is provided by a number of telecommunication companies like Axerra Networks, MCI Inc, or by Infrastructure as a service providers like Voxility. There are now many pseudowire standards, the most important of which are IETF RFCs as well as ITU-T Recommendations: (en)
  • Dans les réseaux informatique et les télécommunications, un pseudowire (ou pseudo-wire) est une émulation d'une connexion point a point sur un réseau a commutation de paquets (PSN). Le pseudowire émule le fonctionnement d'un "cable transparent" portant le service, mais on se rend compte que cette émulation sera rarement parfaite. Le service passant sur le pseudowire peut être l'Asynchronous Transfert Mode (ATM), Frame Relay, Ethernet ou Time-division multiplexing (TDM), tandis que le réseau de paquets peut être Multiprotocol Label Switching (MPLS), le protocole Internet (IPv4 ou IPv6), ou Layer 2 Tunneling Protocol Version 3 (L2TPv3). Les premières spécifications de pseudowire ont été le draft Martini pour les pseudowires ATM, et la draft TDMoIP pour le transport de E1/T1 sur IP. En 2001, l'Internet Engineering Task Force (IETF) a mis en place le groupe de travail , qui a été chargé de développer une architecture de pseudowire edge-to-edge pour les fournisseurs de services, et de fournir les documents de spécification détaillant les techniques d'encapsulation. D'autres organismes de normalisation, y compris l'Union internationale des télécommunications (UIT) et le Forum de l'MFA, sont également actives dans la production de normes et d'accords d'implémentation pour les pseudowires.

  • 의사회선(Pseudo-wire)은 컴퓨터 네트워크와 통신에서 기존 통신 서비스를 상에서 제공하는 것이다. 여기에서 기존 통신 서비스란 ATM 혹은 Frame Relay, 이더넷, 저속 TDM, SDH/SONET 등을 의미하며 패킷 기반 네트워크는 MPLS 또는 IP (IPv4 혹은 IPv6), L2TPv3 등을 의미한다. (ko)
  • Псевдопроводная технология (англ. pseudo-wire) обеспечивает эмуляцию традиционных сервисов по сетям с коммутацией пакетов. Псевдопроводная технология позволяет прозрачно передавать ATM, Frame relay, Ethernet, низкоскоростной TDM или SDH/SONET поверх сетей с пакетной коммутацией MPLS, IP (IPv4 или IPv6) или L2TPv3. Первыми псевдопроводными спецификациями были Martini draft (ATM сервис посредством MPLS сети) и TDMoIP (E1/T1 через IP сети) компании RAD Data Communications. Специальная комиссия интернет-разработок (IETF) в 2001 году создала рабочую группу PWE3, целью которой была стандартизация механизмов псевдопроводной эмуляции каналов. В разработке стандартов псевдопроводных технологий участвовали и другие форумы по стандартизации, такие как MEF и MFA, ITU. К наиболее распространенным стандартам псевдопроводной передачи относятся: TDMoIP, TDMoP, CESoPSN, SAToP, и HDLCoPSN. (ru)
