The Solaris Federated Services architecture extends the distributed computing foundation to enable users to access resources across a heterogeneous network supporting services from many different vendors. Solaris can now link multiple autonomous distributed services in "plug and play" fashion, allowing them to co-exist and cooperate on the network in a manageable and consistent way. This article articulates the Federated Services approach and details the concurrent activities underway by SunSoft and its partners. ** Network "The State(lessness) of Being: An NFS Update," by SMCC's Hal Stern, was originally published, in much shorter form, in Hal's /sys.admin column in SunWorld magazine. This month, we present the entire, unabridged version of the article, which describes how system enhancements can dramatically improve NFS performance and reliability in a distributed computing environment. The article explores various NFS-related research and development efforts of recent years, and what they imply about NFS performance, administration, scalability, security, etc. We also include "Network Load: X-terminals vs. Workstations," by SMCC Technical Product Marketing personnel. This is a brief summary of a recent study comparing the network overhead of workstations and X-terminals. ** SPARC "SRMMU, TLBs, and Contexts" is an overview of virtual-to-physical address translation on a SPARC system. The article discusses the low-level architecture and implementation of virtual memory on SPARC, concentrating on the SPARC Reference Memory Management Unit (SRMMU), the Translation Lookaside Buffer (TLB), and the concept of a process's context. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ For information send mail to info-sunflash@Sun.COM.
