The class is designed to run for 5 days, but has been broken into a 2 day class that covers just the networking and a 3 day class covering everything else. So, if you cannot take off for an entire week, you can get just the part that you need. The descriptions of the two courses are given below followed by contact information to get a more detailed course description and/or to sign up. UNIX Kernel Internals: Data Structures, Algorithms, and Performance Tuning Monday - Wednesday, October 11-13, 1993 Dr. Marshall Kirk McKusick Author and Consultant Description ----------- This course will provide a firm background in the UNIX kernel. The course includes coverage of most BSD-derived kernels including USL's System V Release 4, Sun's Solaris, and DEC's Ultrix. 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 introduction to the interprocess and networking capabilities of the system will provide an overview of networking terminology and an example use of the socket interface. Those wishing to learn about networking internals should take the companion course which immediately follows this one. 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. UNIX Networking Internals Thursday - Friday, October 14-15, 1993 Michael J. Karels Berkeley Software Design, Inc. Description ----------- The course will cover the 4.4BSD kernel network architecture, layering and implementation. The major changes since 4.3BSD will be described, including changes to the socket interface to accommodate the OSI networking protocols. Many of the changes are included in the 4.3BSD-Tahoe or 4.3BSD-Reno release, or the latest unencumbered release, BSD Networking, Release 2. These releases 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 look at work in progress to improve the flexibility and performance of the system. The presentations will emphasize code organization, data structure navigation, and algorithms. It will not cover the machine specific parts of the system such as network device drivers.
