Embodiment Construction

[0021] figure 1 An illustrative physical layout diagram for implementing a distributed operating system is shown in . The layout includes a local computer system 110 and a remote computer system 112 interconnected via a communication network 140 . Although local computer system 110 and remote computer system 112 are illustrated with certain characteristics, the physical configuration and electrical components of the systems are shown as one example only for illustrating the invention. Similarly, communication network 140, which enables message passing between two computer systems 110 and 112, may also take a variety of physical forms and different communication protocols. Since the data passed between the two computer systems 110 and 112 is messages, the data is independent of the medium used for communication. Therefore, the type of communication network is of little relevance to the invention.

Abstract

An improved distributed operating system over a network of computer systems is described. Existing distributed operating systems have transmission performance limitations dictated by their inability to (1) reliably handle transient communication failures and rapid node reboots, (2) provide a transmission protocol that adapts to link reliability, and (3) allow transmissions to occur over an arbitrary combinations of communication links. The systems and methods described herein solve these problems by providing a reliable node-to-node session protocol that offers high performance message delivery and multi-interface management and support. This is done by transmitting all data between two nodes of the operating system over a single connection that may dynamically exploit multiple interfacesbetween the nodes.

Description

technical field [0001] The present invention generally relates to computers; network systems, and more particularly to distributed operating systems on computer network systems. Background technique [0002] An operating system (OS) is system software responsible for controlling and managing computer resources. A typical OS can perform communication between computer application software and hardware. The OS allows application software to access computer hardware and perform basic system operations of the computer, such as disk access, memory management, task scheduling, and user interface. In addition, the OS is also responsible for providing network connectivity. [0003] A computer network provides a mechanism for sharing files and peripherals among multiple interconnected computers. Ideally, a computer network should allow all computers and applications to access all network resources, optimizing collective resources. To achieve this result, distributed operating syst...
