- Provider Backbone Bridge Traffic Engineering (PBB-TE) is an approved telecommunications networking standard, IEEE 802.1Qay-2009. PBB-TE adapts Ethernet technology to carrier class transport networks. It is based on the layered VLAN tags and MAC-in-MAC encapsulation defined in IEEE 802.1ah (Provider Backbone Bridges (PBB)), but it differs from PBB in eliminating flooding, dynamically created forwarding tables, and spanning tree protocols. Compared to PBB and its predecessors, PBB-TE behaves more predictably and its behavior can be more easily controlled by the network operator, at the expense of requiring up-front connection configuration at each bridge along a forwarding path. PBB-TE Operations, Administration, and Management (OAM) is usually based on IEEE 802.1ag. It was initially based on Nortel's Provider Backbone Transport (PBT). PBB-TE's connection-oriented features and behaviors, as well as its OAM approach, are inspired by SDH/SONET. PBB-TE can also provide path protection levels similar to the UPSR (Unidirectional Path Switched Ring) protection in SDH/SONET networks. (en)
- Dans le domaine des télécommunications, Provider Backbone Bridge - Traffic Engineering (PBB-TE), également connu sous le nom de Provider Backbone Transport (PBT), est un protocole de communication Ethernet de classe opérateur. Il repose sur des extensions du protocole Ethernet natif, protocole de niveau 2 habituellement utilisé dans les réseaux locaux d'entreprise, afin de le rendre plus fiable, extensible et déterministe et qu'il puisse être utilisé comme protocole de transport dans les réseaux de grande dimension, notamment les réseaux de nouvelle génération des fournisseurs de services de télécommunications. PBT reprend en particulier les concepts de marquage de VLAN selon la spécification IEEE 802.1Q, "Q-in-Q" selon la spécification IEEE 802.1ad (Provider Bridging) et "MAC-in-MAC" selon la spécification IEEE 802.1ah (Provider Backbone Bridge ou "PBB"). Mais PBB-TE désactive le concept de "flooding/broadcasting" et le protocole "spanning tree". PBB-TE a été normalisé en 2009, par l'IEEE sous l'intitulé 802.1qay. (fr)
- IEEE 802.1Qay 또는 PBB-TE(Provider Backbone Bridge Traffic Engineering)는 승인된 통신 네트워크 표준이다. PBB-TE는 캐리어 클래스 전송 네트워크에 이더넷 기술을 채용한다. 이것은 IEEE 802.1ah에 정의된 계층화 가상 랜(VLAN) 태그와 MAC-in-MAC 캡슐화를 기반으로 한다. (ko)
- Il PBB-TE (acronimo inglese di Provider Backbone Bridges - Traffic Engineering) è una tecnologia di trasporto basata su Ethernet per reti geografiche di telecomunicazione dati e telefonia a commutazione di pacchetto. L'obiettivo di questa tecnologia è apportare una serie di estensioni e di miglioramenti della tecnologia Ethernet tradizionale in modo da ottenere funzionalità di trasporto, monitoraggio e protezione di rete secondo le caratteristiche delle reti di telefonia tradizionali (trasporto di tipo Carrier Class).

- PBB-TE (пи-би-би-ти-и, англ. Provider Backbone Bridge Traffic Engineering - магистральные мосты провайдера с возможностью оптимизации и управления трафиком) — пакетная технология передачи данных, принятая как стандарт IEEE 802.1Qay-2009. PBB-TE адаптирует технологию Ethernet для применения в транспортных сетях провайдеров. В основе стандарта лежат технологии Q-in-Q (стандарт ) и MAC-in-MAC (стандарт IEEE 802.1ah), но в отличие от них из PBB-TE удалена функциональность широковещательных запросов, динамических таблиц коммутации и отсутствуют протоколы покрывающего дерева. В сетях PBB-TE (англ. Operations, administration and management - эксплуатация, управление и техническое обслуживание) как правило базируются на стандарте . (ru)
