TL;DR: A service level agreement is a contract between a supplier and a customer that identifies services supported by a network, service parameters for the services, and service levels (e.g., acceptable levels) for each service parameter.
Abstract: Method and apparatus for service level management, wherein business processes are composed of services. A state of the service is defined by one or more service parameters, and the service parameters depend upon performance of network components that support the service, e.g., component parameters. The state of the service may depend, for example, on a collection of service parameter values for availability, reliability, security, integrity and response time. A service level agreement is a contract between a supplier and a customer that identifies services supported by a network, service parameters for the services, and service levels (e.g., acceptable levels) for each service parameter.

TL;DR: In this research, the service level agreements for a service composition are established through autonomous agent negotiation and an innovative framework is proposed in which the service consumer is represented by a set of agents who negotiate quality of service constraints with the service providers for various services in the composition.

TL;DR: In this paper, a grid service broker comprises a central service broker and distributed service brokers, and the central broker uses meta-scheduling for distributing service requests to the distributed service broker based on projected service units needed to process the requests.
Abstract: For providing a service-centric approach to allocating computing service power to users in a heterogeneous distributed computing environment such as a grid, a grid service broker comprises a central service broker and distributed service brokers. Service power is measured in resource-independent service units defined and used by the service broker. The central service broker uses meta-scheduling for distributing service requests to the distributed service brokers, based on projected service units needed to process the service requests.

TL;DR: This book offers network architects, engineers, and managers of Internet and other packet networks critical insight into the continuing development of Differentiated Services.
Abstract: From the Publisher: Differentiated Services is an Internet Engineering Task Force (IETF) standards effort to create a simple scheme which provides a range of quality of service (QoS) levels. It is one of the few technologies to date that will enable networks to handle traffic in a specific manner to meet the service demands of particular applications. This book offers network architects, engineers, and managers of Internet and other packet networks critical insight into the continuing development of Differentiated Services. Differentiated Services for the Internet includes: Exploration of how Diffserv can be used to diversify Internet service offerings Detailed evaluation of the advantages and disadvantages of Differentiated Services (Diffserv) in comparison to traditional best effort network services Coverage of the IETF's Diffserv specification-the necessary basis for implementations of the technology Detailed coverage of interworking Diffserv with Integrated Services (Intserv) networks

TL;DR: This document describes the Provider Architecture for Differentiated Services and Traffic Engineering (PASTE) for Internet Service Providers (ISPs) and the challenges faced in providing differentiated services in ISPs.
Abstract: This document describes the Provider Architecture for Differentiated Services and Traffic Engineering (PASTE) for Internet Service Providers (ISPs). Providing differentiated services in ISPs is a challenge because the scaling problems presented by the sheer number of flows present in large ISPs makes the cost of maintaining per-flow state unacceptable. Coupled with this, large ISPs need the ability to perform traffic engineering by directing aggregated flows of traffic along specific paths.
