Netzwerkmanagement und Hochleistungskommunikation. Teil XXIV. Seminar SS 2001

This Technical Report includes student papers produced within a seminar of "Network Management and High Performance Communications". For the 24nd time this seminar has attracted a large number of diligent students, proving the broad interest in topics of network management and high performance ommunications. The topics of this report may be coarsely divided into two blocks: One block is devoted to high speed and high performance technology. At first, the concept of modern High Speed Switches and Routers with quality-of-service support is described. Subsequently, Efficient Methods and Algorithms for Routing Table Lookups as well as Classification of IP Packets and multiprotocol Label Switching (MPLS) are presented. A second block deals with various topics such as wireless communications, network management and security. The first article shows advantages of the Policy-based Networks to manage todays networks. Furthermore, Security Extensions of DNS for secure use of the domain name service are examined and presented. The next article describes how to use mobility profiles in mobile ad-hoc networks. Methods for watermarking of multimedia data are discussed in a subsequent article. Moreover, Technical Challenges and Solutions for IP-telephony are also presented, whereby the Stream Control Transmission Protocol is described separately as an approach to achieve a better transport of signaling messages over the Internet. The last article deals with group communication and shows New Approaches for Multicast Routing as well as an overview of some Multicast transport protocols
