Overview

In the collaboration content sphere, there is a growing demand for interoperability between the existing services, potentially offered by different providers, to provide novel functionality. We are talking about a convergence between instant messaging, presence, email, Voice over IP, Push-to-Talk, discussion forums, and other technologies where a mix-and-match between each pair has a potential added value. We envision combined audio/text conferences for heterogeneous handsets, multilingual conferences with automatic bidirectional translation, persistent chats, and presence logging.

The blend between realtime communication and searchable content storage is particularly interesting. Capturing and storing text, presence, and rich media for future retrieval and analysis is extremely valuable for the customer for two reasons. Firstly, it blurs the border between synchronous (IM style) and asynchronous (email style) collaboration and creating a new customer experience. Secondly, it drives the regulation compliance for wiretapping, managing, and searching the information flowing in corporate communication channels.

The Pesto+ project will implement an extensible platform that allows deploying and enabling programmable agents to capture and transform the realtime content streams. These agents connect out-of-band to one or more content communication and/or management services as a regular client to provide add-on functionality, like logging chats, for example. This approach allows the co-existence of the new applications with the legacy applications offered by service providers.

The infrastructure needs will provide the means for managing diverse server-side clients. Management includes the creation, deletion, starting, stopping, and finding of server-side clients.

Pesto+ heavily relies on SIP as a next-generation control protocol of the communication services, and SIMPLE as a SIP extension for instant messaging and presence information. Integrating the Pesto agents with the service providers in a standard-based manner guarantees interoperability with a broad range of SIP-enabled extended services.
