The description of the course is given below followed by contact information to get a more detailed course description and/or to sign up. UNIX Kernel Internals: Implementation, Tuning, and Networking Dr. Marshall Kirk McKusick University of California at Berkeley Michael J. Karels Berkeley Software Design, Inc. 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 includes 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. In North America it will be taught in a one week short-course format: "UNIX Kernel Internals: Implementation, Tuning, and Networking", March 6-10, 1995, price $1495, includes course notes and textbook.

This class will be limited to 40 students, so if you are interested, you should sign up soon: "UNIX Kernel Internals: Implementation, Tuning, and Networking", 30 January - 3 February 1995, price DM2675 includes course notes, room and board (15:00 Sunday 29 January through 10:00 Saturday 4 February). The facility also includes a computer lab with various different workstations connected to the Internet. For further information contact: Angelika Mueller <off...@dag.uni-sb.de> In the Bay Area the course will be taught in a twelve week format meeting on Thursday nights. This will allow time for students to do homework assignments and to assimilate the material at a more leisurely pace. Note that only McKusick will be teaching this course, so there will be less networking emphasis than in the other two offerings: "UNIX Kernel Internals: Data Structures, Algorithms, and Performance Tuning" February 9 - May 4, 1995 (except April 13), price $1395, includes course notes and textbook.
