Survivability Architectures: Issues and Approaches
نویسندگان
چکیده
Survivability architectures enhance the survivability of critical information systems by providing a mechanism that allows the detection and treatment of various types of faults. In this paper, we discuss four of the issues that arise in the development of such architectures and summarize approaches that we are developing for their solution.

Requirements Definition for Survivable Network Systems
Pervasive societal dependency on large-scale, unbounded network systems, the substantial risks of such dependency, and the growing sophistication of system intruders, have focused increased attention on how to ensure network system survivability. Survivability is the capacity of a system to provide essential services even after successful intrusion and compromise, and to recover full services i...
متن کاملSurvivability in IP over WDM networks
The Internet is emerging as the new universal telecommunication medium. IP over WDM has been envisioned as one of the most attractive architectures for the new Internet. Consequently survivability is a crucial concern in designing IP over WDM networks. This paper presents a survey of the survivability mechanisms for IP over WDM networks. A number of optical layer protection techniques have been...

IP over Optical is being envisioned as one of the most attractive architectures for the new Internet. There have been various proposals in IETF and other international standards organizations regarding the interaction of IP routers and Optical core networks. This paper describes the architectural alternatives for the integration of IP and DWDM networks using Multiprotocol Lambda Switching (MPLa...
متن کاملSurvivability and Resiliency of Spacecraft and Space-Based Networks: A Framework for Characterization and Analysis
Considerations of survivability and resiliency have always been of importance in the design and analysis of military systems. Over the past two decades, the importance of survivability and resiliency has expanded beyond military systems to include public networks and infrastructure systems. The analysis and assessment of networked systems with respect to survivability has become particularly ac...
متن کاملMulti-attribute Tradespace Exploration
Survivability is the ability of a system to minimize the impact of a finite-duration disturbance on value delivery (i.e., stakeholder benefit at cost), achieved through (1) the reduction of the likelihood or magnitude of a disturbance, (2) the satisfaction of a minimally acceptable level of value delivery during and after a disturbance, and/or (3) a timely recovery. Traditionally specified as a...
