Karels, Berkeley Software Design, Inc. Date: January 30 - February 3, 1995 Location: International Conference and Research Center for Computer Science Schloss Dagstuhl, D-66687 Wadern, Germany Fee: DM 2000.- inclusive course notes Accommodation: 33 single and 6 double rooms, all with private facilities are reserved at Schloss Dagstuhl for a charge of DM 135 (DM 85 in double room) per person and day for room and board. UNIX machines are available, connected to the InterNet. Every participant will have his personal account. Information: office@dag.uni-sb.de Registrations are on the basis of first come first served. The attendance is limited to 45 participants. Description ----------- This course will provide a firm background in the UNIX kernel. The course includes coverage of most BSD-derived kernels including Novell's System V Release 4, Sun's Solaris, and DEC's OSF/1. The POSIX kernel interfaces will be used as examples where they are defined. Where they are not defined, the BSD interfaces will be described and then related to other vendors interfaces. The course will cover basic kernel services, process structure, virtual and physical memory management, scheduling, paging and swapping. The kernel I/O structure will be described showing how I/O is multiplexed, special devices are handled, character processing is done, and the buffer pool is managed. The implementation of the filesystem and its capabilities will be described. The filesystem interface will then be generalized to show how to support multiple filesystem types such as Sun Microsystem's Network File System (NFS). Other related topics include performance measurement, system tuning, and security issues. The networking half of the course will start with an overview of networking terminology and an introduction to the interprocess communication interface (sockets). The course will then describe the 4.4BSD kernel network architecture, layering and implementation. This architecture, available in both 4.4BSD and the unencumbered 4.4BSD-Lite, serve as the basis for the networking code in most versions of UNIX, and in several other systems as well. Routing issues will be covered (including use of the Berkeley routing protocol, routed or "RIP"). The tutorial will also include a detailed overview of the support for multiple networking protocol families and address formats and the generalized layering scheme, including changes made to support the OSI protocols. The system communications primitives and internal layering will be discussed, with emphasis on the interfaces between the layers; the TCP/IP implementation will be used as an example. A detailed discussion of TCP algorithms will include slow start and congestion avoidance. The course concludes with a critique of the current architecture and a look at other alternatives. The presentations will emphasize code organization, data structure navigation, and algorithms. It will not cover the machine specific parts of the system such as device drivers.
