Accessing networked appliances using the session initiation protocol

This document proposes the use of session initiation protocol (SIP) for network-capable appliances. It leverages standard SIP capabilities to directly communicate with appliances even when they are behind firewalls, network address translators (NATs) or other entities that prevent direct end-to-end communication. When combined with the recently proposed instant messaging and presence SIP extensions these techniques become even more powerful to allow the secure and reliable access to appliances in a variety of different networked environments.

An object-oriented interface for a distributed connection manager

Connection management (CM) is the part of the network software architecture for broadband networks that allows for the abstraction and control of multimedia, multiparty connections over heterogeneous communication networks. Network control is accomplished by controlling the switching facilities and allocating transmission and special resources (e.g. multicasters, signal converters and signal combiners). This paper proposes an interface to CM that assumes that both CM and CM clients may be distributed. The CM interface is based on several requirements which call for a simple, flexible, extensible transaction-based interface. The proposed solution uses an object-oriented approach to model a directed graph. The CM interface transport model contains object classes that model the components of a directed graph and are used to represent the network resources and the connectivity among them. An additional object class satisfies the transaction requirements of the interface.<<ETX>>

Trusted Access to Sensitive Information in a Diverse Services Environment

Mobile application service providers are trying to strike a balance between offering personalized services and safeguarding user privacy. Being able to offer targeted and relevant services requires access to sensitive user information, such as health records, financial transactions, preferences, and location. Users, on the other hand, are reluctant to allow access to their sensitive information when no mechanisms are in place to ensure the proper usage of this information. In this paper, we describe TASER, a trusted gateway between service providers and sensitive information owners. TASER ensures that only authorized and reputable service providers are given access to sensitive information required by their services for users that have opted-in to such services.

Enabling Service Aggregation for Providers of Consumer Services and Applications

The OSGi™ service platform is universal middleware for Java-based platforms that provides capabilities for enabling service providers to deploy consumer applications and services via various business models. This paper describes motivation and requirements for a service aggregation business model and describes how OSGi technology supports it.

An integrated service management approach using OSGi technology and ACAP

IP-based, value-added services have great potential to create value for consumers and generate additional revenue streams for service providers. Telcordias adaptive communicating applications platform (ACAP) is a system designed to provide a uniform and integrated service development platform for developing and deploying value-added services. The OSGi/spl reg/ alliance is an industry wide consortium that defined a standard platform that provides lifecycle management services for value-added services. Great synergy exists between ACAP and the OSGi service platform, as ACAP provides support for the service management issues not addressed by OSGi technology, and vice versa. In this paper, we argue for integration of ACAP and the OSGi service platform in order to provide better overall service management. We present a lightweight, cost-effective integration approach.

ASP perspectives on networked appliances

ASPs (application service providers) today provide a means for businesses to outsource their applications thus saving on setup and maintenance costs. This paper presents an example of an ASP providing a service to a specialized networked device: a networked alarm clock. This example is used to illustrate the issues ASPs would need to deal with to provide services to specialized networked devices within a home network.
