Industrial communication networks - High availability automation networks - Part 2: Media Redundancy...
IEC 62439-2:2010 is applicable to high-availability automation networks based on the ISO/IEC 8802-3 (IEEE 802.3) (Ethernet) technology. It specifies a recovery protocol based on a ring topology, designed to react deterministically on a single failure of an inter-switch link or switch in the network, under the control of a dedicated media redundancy manager node. It cancels and replaces IEC 62439…

La CEI 62439-2:2010 concerne les réseaux d'automation à haute disponibilité reposant sur la technologie (Ethernet) ISO/CEI 8802-3 (IEEE 802.3). Elle spécifie un protocole de récupération reposant sur une topologie en anneau, conçu pour réagir de manière déterministe sur une seule défaillance d'une maille inter-étage ou d'un commutateur du réseau, sous le contrôle d'un noeud du…

IEC 62439-4:2010 is applicable to high-availability automation networks based on the ISO/IEC 8802-3 (IEEE 802.3) (Ethernet) technology. It specifies a redundancy protocol that is based on the duplication of the network, the redundancy protocol being executed within the end nodes, as opposed to a redundancy protocol built in the switches. The switchover decision is taken in each node individually…

La CEI 62439-4:2010 est applicable aux réseaux d'automatisation à haute disponibilité basés sur la technologie ISO/CEI 8802-3 (IEEE 802.3) (Ethernet). Elle définit un protocole de redondance basé sur la duplication du réseau, le protocole de redondance étant exécuté dans les n uds terminaux, par opposition à un protocole de redondance intégré aux commutateurs. La décision de commutation est…

IEC 62439-6:2010 is applicable to high-availability automation networks based on the ISO/IEC 8802-3 (IEEE 802.3) (Ethernet) technology. It specifies a recovery protocol based on a ring topology, designed to react deterministically on a single failure of an inter-switch link or switch in the network. Each switch has equal management role in the network. Double rings are supported. It cancels and…

Fibre optic interconnecting devices and passive components performance standard - Part 1-3: General ...
IEC/PAS 61753-1-3:2009(E) is a Publicly Available Specification (PAS) that defines the minimum initial performance, test and measurement requirements and severities which a single-mode connector or cable assembly must satisfy in order to be categorized as meeting IEC Category I (industrial environment). Category I is an addition to environmental categories C, U, O, E described in IEC 61753-1 and…

This National Standard of Canada is equivalent to International Standard ISO/IEC 11770-3:2008.
1 Scope
This part of ISO/IEC 11770 defines key management mechanisms based on asymmetric cryptographic
techniques. It specifically addresses the use of asymmetric techniques to achieve the following goals.
1) Establish a shared secret key for a symmetric cryptographic technique between two entities A…
