TTEthernet switch can implement a reliable redundancy management and dataflow (datastream) integration to assure message transmission even in case of a switch failure. The SAE AS6802 implemented on an Ethernet switch supports the design of synchronous system architectures with defined fault-hypothesis. </p><p>The single-failure hypothesis, dual-failure hypothesis, and tolerance against arbitrary synchronization disturbances define the basic fault-tolerance concept in a Time-Triggered Ethernet (SAE AS6802-based) network. </p><p>Under the single-failure hypothesis, Time-Triggered Ethernet (SAE AS6802) is intended to tolerate either the fail-arbitrary failure of an end system or the fail-inconsistent-omission failure of a switch. The switches in Time-Triggered Ethernet network can be configured to execute a central bus guardian function. The central bus guardian function ensures that even if a set of end systems becomes arbitrarily faulty, it masks the system-wide impact of these faulty end systems by transforming the fail-arbitrary failure mode into an inconsistent-omission failure mode. The arbitrarily faulty failure mode also includes so called "babbling-idiot" behavior. Time-Triggered Ethernet switches therefore establish fault-containment boundaries. </p><p>Under the dual-failure hypothesis, Time-Triggered Ethernet networks are intended to tolerate two fail-inconsistent-omission faulty devices. These devices may be two end systems, two switches, or an end system and a switch. The last failure scenario (i.e., end system and switch failure) means that Time-Triggered Ethernet network tolerates an inconsistent communication path between end systems. This failure mode is one of the most difficult to overcome. </p><p>Time-Triggered Ethernet networks are intended to tolerate transient synchronization disturbances, even in the presence of permanent failures. Under both single- and dual-failure hypothesis, Time-Triggered Ethernet provides self-stabilization properties. Self-stabilization means that synchronization can reestablish itself, even after a transient upset in a multitude of devices in the distributed computer network. </p> <div class="mw-heading mw-heading2"><h2 id="Performance">Performance</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=TTEthernet&action=edit&section=3" title="Edit section: Performance"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="Time-triggered_traffic">Time-triggered traffic</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=TTEthernet&action=edit&section=4" title="Edit section: Time-triggered traffic"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Time-triggered traffic is scheduled periodically, and depending on the architecture, line speed (e.g. 1GbE), topology and computing model with control loops operating at 0.1–5(+) kHz, using a time-triggered architecture (TTA) model of computation and communication.

In this case, time-triggered transmissions are necessarily <a href="/wiki/Cyclic_executive" title="Cyclic executive">cyclically scheduled</a> and thus delays between processes in the application layer can be large, e.g. with <a href="/wiki/Plesiochronous_system" title="Plesiochronous system">plesiochronous</a> processes operating on their own local clock and execution cycle, as is observed in systems using cyclic <a href="/wiki/MIL-STD-1553" title="MIL-STD-1553">MIL-STD-1553</a>B buses, up to twice the transmission interval due to released packets waiting for scheduled transmission at the source and for the receiving process to run at the destination. </p> <div class="mw-heading mw-heading3"><h3 id="Rate-constrained_traffic">Rate-constrained traffic</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=TTEthernet&action=edit&section=5" title="Edit section: Rate-constrained traffic"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Rate-constrained traffic is another periodic time-sensitive traffic class, and it shall be modeled to align with time-triggered traffic (and vice versa) in order to fulfill maximum latency and jitter requirements.

Hence the maximum error in synchronization between the source and the switch must be included in the duration of the time slot that the switch must allow. Otherwise frames of the time-triggered transfer, which are correctly timed from the perspective of the source, will be dropped by the switch for being mistimed. Hence, the larger the errors in the synchronization, the fewer such frames can be transmitted in any given period. This is a particular problem in the use of standard IEEE 802.3 Ethernet network interfaces with software support for IEEE1588 for the transmission of time-triggered transfers, e.g. for provably reliable data transport. This is, partly, why the use of specific TTEthernet network interfaces with hardware support for synchronization, etc., is recommended in implementations of TTEthernet.</span> </li> </ol></div></div> <div class="mw-heading mw-heading2"><h2 id="References">References</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=TTEthernet&action=edit&section=10" title="Edit section: References"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1239543626"><div class="reflist"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-tttech-1"><span class="mw-cite-backlink"><b><a href="#cite_ref-tttech_1-0">^</a></b></span> <span class="reference-text"><style data-mw-deduplicate="TemplateStyles:r1238218222">.mw-parser-output cite.citation{font-style:inherit;word-wrap:break-word}.mw-parser-output .citation q{quotes:"\"""\"""'""'"}.mw-parser-output .citation:target{background-color:rgba(0,127,255,0.133)}.mw-parser-output .id-lock-free.id-lock-free a{background:url("//upload.wikimedia.org/wikipedia/commons/6/65/Lock-green.svg")right 0.1em center/9px no-repeat}.mw-parser-output .id-lock-limited.id-lock-limited a,.mw-parser-output .id-lock-registration.id-lock-registration a{background:url("//upload.wikimedia.org/wikipedia/commons/d/d6/Lock-gray-alt-2.svg")right 0.1em center/9px no-repeat}.mw-parser-output .id-lock-subscription.id-lock-subscription a{background:url("//upload.wikimedia.org/wikipedia/commons/a/aa/Lock-red-alt-2.svg")right 0.1em center/9px no-repeat}.mw-parser-output .cs1-ws-icon a{background:url("//upload.wikimedia.org/wikipedia/commons/4/4c/Wikisource-logo.svg")right 0.1em center/12px no-repeat}body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-free a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-limited a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-registration a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-subscription a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .cs1-ws-icon a{background-size:contain;padding:0 1em 0 0}.mw-parser-output .cs1-code{color:inherit;background:inherit;border:none;padding:inherit}.mw-parser-output .cs1-hidden-error{display:none;color:var(--color-error,#d33)}.mw-parser-output .cs1-visible-error{color:var(--color-error,#d33)}.mw-parser-output .cs1-maint{display:none;color:#085;margin-left:0.3em}.mw-parser-output .cs1-kern-left{padding-left:0.2em}.mw-parser-output .cs1-kern-right{padding-right:0.2em}.mw-parser-output .citation .mw-selflink{font-weight:inherit}@media screen{.mw-parser-output .cs1-format{font-size:95%}html.skin-theme-clientpref-night .mw-parser-output .cs1-maint{color:#18911f}}@media screen and (prefers-color-scheme:dark){html.skin-theme-clientpref-os .mw-parser-output .cs1-maint{color:#18911f}}</style><cite class="citation web cs1"><a rel="nofollow" class="external text" href="https://www.tttech.com/technologies/time-triggered-ethernet/">"Time-Triggered Ethernet"</a>. <i>www.tttech.com</i><span class="reference-accessdate">.
