Steps Toward Self-Aware Networks
Network software adapts to user needs and load variations and failures to provide reliable communications in largely unknown networks.

The distribution of a program in primary and fast buffer storage
A virtual memory computer system with a fast buffer (cache) memory between primary memory and the central processing unit is considered. The optimal distribution of a program between the buffer and primary memory is studied using the program's lifetime function. Expressions for the distribution of a program which maximizes the useful fraction of the cost-time integral of primary and fast buffer storage are obtained for swapping and nonswapping buffer management policies.
Minimizing wasted space in partitioned segmentation
A paged virtual memory system using a finite number of page sizes is considered. Two algorithms for assigning pages to segments are discussed. Both of these algorithms are simple to implement. The problem of choosing the page sizes to minimize the expected value of total wasted space in internal fragmentation and in a page table, per segment, is then solved for a probability density function of segment size which may be expressed as a convex combination of Erlang densities.
