摘要:
A hierarchical system configuration method and an integrated scheduling method for offering a multimedia streaming service on a two-level double cluster system are provided. The hierarchical system configuration method includes the steps of: determining whether one server node exists; if one server node exists, determining whether one virtual server node/specific network storing and merging block exists; and if one virtual server node/specific network storing and merging block exists, setting a system configuration mode for configuring a single virtual server node based multimedia streaming server system and determining a representative network address of a current system, wherein depending on a scale and a characteristic of the multimedia streaming service, a hierarchical multimedia streaming server system is configured into a single virtual server node based system, which is a minimum-scale, a mono-level single virtual cluster based system, which is a medium-scale, and a two-level double cluster based system, which is a maximum-scale.

Provided is a hyperlink display method based on a visit history accumulation, which is capable of providing search convenience between web documents by providing a self-updating hyperlink through accumulation of a visit history. The hyperlink display method includes displaying a plurality of hyperlink included in a web document when the web document is selected, recording a weight value of a selected hyperlink when any one of the plurality of hyperlinks is selected, and displaying the weight value of the selected hyperlink on the web document.
摘要:
Provided are a virtualization based high availability cluster system and a method for managing failures in a virtualization based high availability cluster system. The high availability cluster system includes a plurality of virtual nodes, and a plurality of physical nodes each including a message generator for generating a message denoting that the virtual nodes are in a normal state and transmitting the generated message to virtual nodes in a same physical node. One of the virtual nodes not included in a first physical node among the plurality of the physical nodes takes over resources related to a service if a failure is generated in one of virtual nodes included in the first physical node.
