Bootstrapping: just one zone, the whole world assigned to the first superpeer (Peers with high CPU power, with good network connection, and with a history of long online times, are marked as potential superpeer) Network grows: highly loaded areas clustered into rectangular zones using a clustering algorithm assigned to one peer (preferably to one in that area) Load of the peers… Next slide
  3. Betrachten wir also Scheduling und Active Queue Management Verfahren. Was Active Queue Management ist, werde ich gleich beschreiben. Allgemein geht es darum, dass das System Anfragen an eine Ressource erhält und entscheiden muss, welchem Anfrager wann die Ressource zur Verfügung gestellt wird. Dieses Prinzip ist auf verschiedene Ressourcen anwendbar, wie z.B. Rechenkraft, Bandbreite oder Speicherzugriffe. Wir gehen davon aus, dass die Anfragen in einer Queue zwischengespeichert werden, währen die Ressource in Benutzung ist. Scheduling nennt man nun das Verfahren, dass bestimmt, welches der Anfrager aus der Queue als nächstes Zugriff auf die Ressource erhält, sie bestimmt also die Reihenfolge der Anfrager in der Queue. Die Referenzlösung dafür ist First-In-First-Out. Nun kann es vorkommen, dass die Queue des Systems an ihre Grenzen stößt, da auch sie nur endliche Länge hat. Für diesen Fall gibt es Verfahren, die man unter dem Sammelbegriff Active Queue Management zusammenfasst. Sie entscheiden welche Anfragen aus der Queue entfernt werden, wenn eine Überlast vorliegt. Typisches Beispiel für ein Active Queue Management Verfahren ist Drop Tail, dass alle neu ankommenden Verfahren bei Überlast verwirft. Wir sehen, dass die Scheduling und Active Queue Management Verfahren allgemein für die Ressourcennutzung anwendbar sind. Um nun aber tiefer in die Materie einzusteigen und zu erfahren welche Verfahren es gibt und wo ihre Vor- und Nachteile liegen, habe ich mich mit verschiedenen Lösungen auseinander gesetzt.
