Research initiatives to redesign the Internet are popping up all around the globe. Some claim that the Internet must be redesigned from the information point of view. This approach goes under the banner of information-centrism. In the other hand, other initiatives claim that the design must be centered on the services, i.e. the service-centrism or the Internet of services. And there are also those focusing on decoupling host identifiers from locators to improve mobility support. Which is the right path to follow? We contend that none of them alone, but instead, to integrate synergistically them all. We call this approach the Internet of information and services.

• Research initiatives to redesign the Internet are popping up all around the globe.
• Some initiatives focus on information exchanging, a.k.a. information- or content-centric design, e.g. content-centric networks like NetInf, CCN, PSIRP, NDN.
• Others, focus on service orchestration, a.k.a. service-centric design, e.g. everything-as-a-service or Internet of Services (IoS) approaches, like SOA4ALL, CASCADAS, S-Cube.
• And, there are those concerned with mobility and multihoming support, a.k.a. ID/Loc splitting approaches like MOFI.
Contextualization (2/2)
• Is there a the right path to follow?
• Argument: Why not to integrate them all?
• We call this approach the Internet of Information and Services (IoIS).
• The IoIS paradigm is already being employed on a broad architecture called NovaGenesis.
• This paper proposes a conceptual architecture based on this idea.
Design Principles and Choices (1/2)
• Identification of architectural residents
• Relate legible and self-certifying names
• Dynamic compose-ability and hierarchical modularity
• Resolve indirections generically and recursively
• Use publish/subscribe paradigm
• Accommodate search and discovery
• Cover social relationships among entities
Design Principles and Choices (2/2)
• Accommodate the growth on interactivity
• Design for built-in security, privacy, and trust
• Accommodate neutrality, openness, diversity, flexibility, and extendability of services and applications
Architectural Components (1/2)
• HTS (Hash Table System): A set of processes that stores name-based bindings among entities.
• GIRS (Generic Indirection Resolution System): A process used to decide the most appropriate Hash Table to store some name-based binding.
• PSS (Publish/Subscribe System): It does the rendezvous between publisher and subscriber.
• OBS (Orchestration Broker System): It helps simple services to search, discover, negotiate, and contract service partners.
Architectural Components (2/2)
• RS (Reputation System): It is responsible to determine entities reputation based on the feedbacks received from partners in established SLAs.
• DS (Domain System): It is aimed to actively represents all the systems in a domain.
• SDS (Search and Discovery System): It performs recursive subscriptions to the PSS and filters results according to semantics and context.
Specific pub/sub protocol for service search and discovery.
Compose-ability
Distributed (per se) or centralized (via OBS)
orchestration.
Does not cover explicit service orchestration
mechanisms.
Autonomic self-management of
services is supported by 4WARD INM.
Autonomic life-cycle management of
services.
Conclusion
• Our proposal cohesively integrates information- and service-centric approaches, ID/Loc splitting, pub/sub paradigm, search and discovery, besides other ingredients, in an unique architecture.
• Compared to the related work, IoIS addresses:
• Naming and traceability issues not covered in CASCADAS.
• Dynamic ID-based orchestration and life-cycling management that is missing on XIA.
• Integrated information and services life-cycling capabilities.
