Service Assurance with Partial and Intermittent Resources

SAPIR 2005

Week of July 17, 2005 - Lisbon, Portugal






We are witnessing many technological paradigm shifts imposed by the complexity induced by the notions of fully shared resources, cooperative work, and resource availability.

P2P, GRID, Clusters, Web Services, Delay Tolerant Networks, Service/Resource identification and localization illustrate aspects where some components and/or services expose features that are neither stable nor fully guaranteed.

Examples of technologies exposing similar behavior are WiFi, WiMax, WideBand, UWB, ZigBee, MBWA and others.

Management aspects related to autonomic and adaptive management includes the entire arsenal of self-ilities. Autonomic Computing, On-Demand Networks and Utility Computing together with Adaptive Management and Self-Management Applications collocating with classical networks management represent other categories of behavior dealing with the paradigm of partial and intermittent resources.

Therefore, the Internet, converged networks, ad-hoc networking, sensor networks, and satellite communications require a management paradigm shift that takes into account the partial and intermittent availability of resources (pi-resources), including infrastructure (networks, computing, and storage) and service components, in distributed and shared environments. The term pi-resources becomes the central concept in next generation networks, where optimization, shared resources, mobile resources, autonomic resource or service replacement, self-isolation, partial availability and other features become inherent. A resource is called partial (p-resource) when only a subset of conditions for it to function to complete specification is met, yet it is still able to provide (potentially degraded) service, while an intermittent or sporadic resource (i-resource) will be able to provide service for limited and potentially unpredictable time intervals only.

Partial and intermittent services (pi-services) are relevant in environments characterized by high volatility and fluctuation of available resources, such as experienced in conjunction with component mobility or ad-hoc networking, where the notion of traditional service guarantees is no longer applicable. Other characteristics, such as large transmission delays and storage mechanisms during the routing, require a rethinking of today's paradigms with regards to service assurance and how service guarantees are defined.

The SAPIR conference stresses debates and focuses on different aspects and challenges in defining, deploying, and maintaining partial and intermittent resources that may collocate with traditional resources. The workshop focuses on new applications, semantics, models, and associated management mechanisms for partial and intermittent resources.
