'''Stephen R. Covey''' (born October 24, 1932 in [[Salt Lake City, Utah]]) wrote the best-selling book, ''[[The Seven Habits of Highly Effective People]]''. Other books he has written include ''First Things First'', ''Principle-Centered Leadership'' and ''The Seven Habits of Highly Effective Families''. His {{As of|2007|alt= latest}} book, ''[[The 8th Habit: From Effectiveness to Greatness|The 8th Habit]]'', appeared in 2004. |
|||
Split-Horizon-Verfahren finden in den Protokollen [[Routing Information Protocol|RIP]], [[Interior Gateway Routing Protocol|IGRP]] und [[VPLS]] Anwendung. |
|||
Covey lives with his wife Sandra and their family in [[Provo, Utah]], home to [[Brigham Young University]], where Dr. Covey taught prior to the publication of his best-selling book. A father of nine and a grandfather of forty-nine with his wife, he received the Fatherhood Award from the [[National Fatherhood Initiative]] in 2003. |
|||
== Funktionsweise == |
|||
Covey established the "Covey Leadership Center" which, in 1997, merged with Franklin Quest to form [[FranklinCovey]], a global professional-services firm and specialty-retailer selling both training and productivity-tools to individuals and to organizations. Their [[mission statement]] reads: "We enable greatness in people and organizations everywhere". |
|||
Bei Split Horizon werden in der Routingtabelle die Anzahl der Hops und der Zwischenrouter bis zu einem Zielnetz gespeichert sowie von welchem Router die Informationen empfangen wurden. |
|||
Ein Router sendet die über eine seiner Schnittstellen empfangenen Routinginformationen über ein bestimmtes Netzwerk zwar über alle anderen Schnittstellen weiter, aber nicht über die Schnittstelle, über welche er eben dieses Netzwerk ursprünglich erlernt hat, zurück. |
|||
In 2008, Covey launched [http://www.stephencovey.com/goal The Stephen Covey's Online Community]. The site is a mash up of online courses, goal management and social networking. He uses it as a place to teach his most recent thoughts and ideas on current topics and self leadership. |
|||
== Beispiel == |
|||
Covey holds a [[Bachelor of Science| BS]] degree in Business Administration from [[University of Utah]] in Salt Lake City, an [[Master of Business Administration|MBA]] from [[Harvard University]], and a [[Doctor of Religious Education| Doctorate of Religious Education]] (DRE) in LDS ([[The Church of Jesus Christ of Latter-Day Saints]]) Church History and Doctrine from Brigham Young University. He also holds membership of the [[Pi Kappa Alpha]] International Fraternity. |

''[[The Seven Habits of Highly Effective People]]'', Covey's best-known book, has sold more than 15 million copies worldwide since its first publication in 1989. (The audio version became the first non-fiction audio-book in U.S. publishing history to sell more than one million copies.) Many of the ideas and much of the language recast the content of the classic 1966 [[Peter F. Drucker]] book ''The Effective Executive'', wherein Drucker wrote: "Effectiveness, in other words, is a habit",{{Fact|date=December 2007}} and which includes a chapter called "First Things First". In Covey's version, he argues against what he calls "The Personality Ethic", something he sees as prevalent in many modern self-help books. He instead promotes what he labels "The Character Ethic": aligning one’s values with so-called "universal and timeless" principles. Covey adamantly refuses to confound principles and values; he sees principles as external [[natural law]]s, while values remain internal and subjective. Covey proclaims that values govern people’s behavior, but principles ultimately determine the consequences. Covey presents his teachings in a series of habits, manifesting as a progression from dependence via [[independence]] to [[interdependence]]. |

'''Ausfall eines Routers: Router A nicht zu erreichen''' |
|||
===The 7 Habits=== |
|||
Netz N0 --> Router A <-X X-> Router B <------------> Router C |
|||
* Habit 1: Be Proactive: Principles of Personal Choice |
|||
* Habit 2: Begin with the End in Mind: Principles of Personal Vision |
|||
* Habit 3: Put First Things First: Principles of Integrity & Execution |
|||
* Habit 4: Think Win/Win: Principles of Mutual Benefit |
|||
* Habit 5: Seek First to Understand, Then to be Understood: Principles of Mutual Understanding |
|||
* Habit 6: Synergize: Principles of Creative Cooperation |
|||
* Habit 7: Sharpen the Saw: Principles of Balanced Self-Renewal |

=== Ohne Split Horizon === |
||
* Router B lernt beim nächsten Update von Router C, dass Router A über ihn in 2 Hops (ursprünglich von C zu B und von B zu A) zu erreichen ist. |
|||
Follow-up titles to ''The Seven Habits'' aim both to add to the original and to form a cohesive philosophy on personal, principle-based [[leadership]]. They come in the format of [[audio books]] as well (such as the title ''Beyond The 7 Habits''). Covey has also written a number of learning-books for children. His son, [[Sean Covey]], has written a version for teens: ''The Seven Habits of Highly Effective Teens''. This version simplifies Covey's 7 Habits for younger readers to better understand them. |
|||
* Router B passt die Routingtabelle an und erhöht die Hopanzahl um 1. |
|||
* Beim nächsten Update lernt Router C von B, dass der Router A nun mit 3 Hops über Router B zu erreichen ist. |
|||
* Beim nächsten Update erhält Router B von C die Information, dass Router A nun mit 4 Hops zu erreichen ist. |
|||
Damit ist eine Routingschleife entstanden die bis zu 16 Hops, der maximal möglichen Anzahl von Zwischenstationen bei [[Routing Information Protocol|RIP]] hochzählt. Erst dann wird die Route zu Router A als unerreichbar markiert. Da Updates alle 30 Sekunden ausgetauscht werden, kann es 15 mal 30 Sekunden, also gute sieben Minuten dauern, bis der Ausfall eines Routers erkannt und die Verbindung zu ihm als unerreichbar markiert wird. |
|||
==''The 8th Habit''== |
|||
Covey's {{As of|2007|alt= latest}} book ''[[The 8th Habit: From Effectiveness to Greatness]]'' (published in 2004) functions as the sequel to ''The Seven Habits''. Covey claims that [[effectiveness]] does not suffice in what he calls "The [[knowledge worker|Knowledge Worker]] Age". He proclaims that "[t]he challenges and complexity we face today are of a different order of magnitude." The 8th habit essentially urges: "Find your voice and inspire others to find theirs..." |

* Router B sendet beim nächsten Update an Router C, dass Router A nicht erreichbar ist. |
|||
In March 2008 Covey launched the [http://www.stephencovey.com/goal/ Stephen Covey's Online Community]. The site is a mash up of online courses, goal management and social networking. Covey uses it as a place to teach his most recent thoughts and ideas on current topics and self leadership, his books as well as goal setting and reaching. The content is shared via videos, podcasts, printable text and online activities. Users are also able to set personal goals, track their progress and share their progress with others within the community. The community is currently growing at a rate of over 1000 users a week. |
|||
* Router C passt die Routingtabelle an, sendet aber die erhaltene Information nicht wieder an Router B zurück, weil er bei Split Horizon ihm nichts sagt was er von ihm gelernt hat. |

Beim Split Horizon With Poisoned Reverse (= mit blockierter Rückroute) werden alle über diese Schnittstelle gelernten/empfangenen Routen als „nicht erreichbar“ gekennzeichnet und zurückgesendet, indem die Anzahl der Hops direkt auf 16, die maximale Anzahl gesetzt wird. |
|||
As a practicing member of [[The Church of Jesus Christ of Latter-day Saints]], Stephen Covey has authored several devotional works for [[Latter-day Saint]] or [[Mormon]] readers, including: |

Split Horizon und Split Horizon With Poisoned Reverse sind Verfahren der Computer-Netzwerktechnik und werden bei bestimmten Routing-Protokollen verwendet, um beim Informationsaustausch zwischen Routern Routingschleifen zu vermeiden.
Split-Horizon-Verfahren finden in den Protokollen RIP, IGRP und VPLS Anwendung.
Funktionsweise
Bei Split Horizon werden in der Routingtabelle die Anzahl der Hops und der Zwischenrouter bis zu einem Zielnetz gespeichert sowie von welchem Router die Informationen empfangen wurden.
Ein Router sendet die über eine seiner Schnittstellen empfangenen Routinginformationen über ein bestimmtes Netzwerk zwar über alle anderen Schnittstellen weiter, aber nicht über die Schnittstelle, über welche er eben dieses Netzwerk ursprünglich erlernt hat, zurück.
Beispiel
Router C „weiß“ von Router B, dass das Netzwerk N0 über Router A zu erreichen ist.
Normalzustand:
Netz N0 --> Router A <----------> Router B <------------> Router C
Ausfall eines Routers: Router A nicht zu erreichen
Netz N0 --> Router A <-X X-> Router B <------------> Router C
Ohne Split Horizon
- Router B lernt beim nächsten Update von Router C, dass Router A über ihn in 2 Hops (ursprünglich von C zu B und von B zu A) zu erreichen ist.
- Router B passt die Routingtabelle an und erhöht die Hopanzahl um 1.
- Beim nächsten Update lernt Router C von B, dass der Router A nun mit 3 Hops über Router B zu erreichen ist.
- Beim nächsten Update erhält Router B von C die Information, dass Router A nun mit 4 Hops zu erreichen ist.
Damit ist eine Routingschleife entstanden die bis zu 16 Hops, der maximal möglichen Anzahl von Zwischenstationen bei RIP hochzählt. Erst dann wird die Route zu Router A als unerreichbar markiert. Da Updates alle 30 Sekunden ausgetauscht werden, kann es 15 mal 30 Sekunden, also gute sieben Minuten dauern, bis der Ausfall eines Routers erkannt und die Verbindung zu ihm als unerreichbar markiert wird.
Mit Split Horizon
- Router B sendet beim nächsten Update an Router C, dass Router A nicht erreichbar ist.
- Router C passt die Routingtabelle an, sendet aber die erhaltene Information nicht wieder an Router B zurück, weil er bei Split Horizon ihm nichts sagt was er von ihm gelernt hat.
Split Horizon With Poisoned Reverse
Beim Split Horizon With Poisoned Reverse (= mit blockierter Rückroute) werden alle über diese Schnittstelle gelernten/empfangenen Routen als „nicht erreichbar“ gekennzeichnet und zurückgesendet, indem die Anzahl der Hops direkt auf 16, die maximale Anzahl gesetzt wird.
