Quality of Service in IP Networks
IP networks were designed some 25 years ago. Networks based on TCP/IP are
widely deployed, as organization-local Intranets as well as in the Internet
itself. The usage patterns of those networks change. Especially new
technologies like voice-over-IP as well as streaming multimedia applications
have different requirements on the underlying network infrastructure than
bulk data transfers like ftp/www or interactive traffic like telnet/ssh.
Organizations usually run a mixture of different services on their Internet
uplinks or on their organization-internal wide area networks. Bandwidth is
usually a limited ressource, so everybody wants to divide bandwidth between
different services according to his specific needs.
Linux always had a very strong focus on network functionality and has
sophisticated means for bandwidth control / QoS since Kernel 2.2.
The presentation is organized in the following parts:
Basics of QoS in IP networks
How can Linux help with QoS
Sample scenarios of Linux-based QoS solutions
Overview about advanced conecpts (DiffServ, IntServ, RSVP, ...)
