It’s the solution to (almost) all your problems

It uses a single self-protected container, named Versatile Digital Item (VDI), to transport and

describe any content.

Search engines can exploit VDI description and metadata for indexing

It is an open source technology, bringing together Information Centric Networking (ICN) and MPEG middleware

Users can: • publish, search and subscribe to any content

• wrap content (e.g. video) and its description in a VDI, specify its name, set rights to it

(e.g. who can see the video, where and for how much time), and publish it to the network

• update or revoke (digital forgetting!) content, even after it has been published, and monitor its

use, and communicate with people using it

The network knows the content name and makes sure you always access the copy closest to you;

every node is a cache; handover is easy; multicast is natural, peer-to-peer is built-in,

time/space-decoupling is possible

Developers do not need to use proprietary/ad hoc solutions for common/supporting functionality as

they can exploit CONVERGENCE’s middleware and ICN

Operators can use the network more efficiently, differentiate the quality of service as a function of

content names, better control information transfer and related revenues flows, and simplify network

design, operation and management by integrating in the network diverse functions, avoiding patches

and stopgap solutions

CONVERGENCE’s modular architecture and interfaces allow for a smooth evolution from current

networks; its design, together with recent initiatives such as Software Defined Networking and Network

Functions Virtualisation, give hope that these ideas will not necessarily remain a dead letter just because

“we cannot change the whole Internet”…

CONVERGENCE

Enhancing the Internet with an information-centric, publish-subscribe

service model, based on a common container for any kind of digital data,

including representations of people and Real World Objects

Network Applications

Six real-worlds applications & trials

1. Professional photography, making it

easier for photographers to contribute

and describe photos, improving access

for users and facilitating management

2. Audiovisual archives, exploiting

semantic techniques, when the same

videos are used in different contexts

3. Podcasts with synchronized slides,

which are annotated by students in a

social learning environment

4. Retailing supply chain for electronic

products; lifecycle management of VDI-

enabled Real-World Objects in a large

retailer/shopping mall; logistics, in store

& on shelf management, warehousing

• Two integrated applications: the first one

integrates video and podcasts (2+3); the

second one integrates photo and retail

(1+4)->they show the power of VDI

• Network experiments over OFELIA

(OpenFlow) and OpenLab (PlanetLab)

ISO-MPEG based (MPEG-M)

• Publish-Subscribe operations

• Semantic searches/matches

• Security functions (exploiting smart

cards, and Attribute-Based Encryption)

• Approved contributions to International

Standards:

• MPEG-21 DII amendment for Semantic

Relationships

• New MPEG-M services for Post and

Revoke Content

• MPEG-M Reference Software

Advantages

• It allows building applications that exploit and

add value to CONVERGENCE functionalities,

without having to use proprietary solutions

• It relieves the network layer from complex

functions (which are executed on a subset of

all nodes) and can operate on any network

• Modular architecture and interfaces allow for

a smooth evolution from current networks

Information Centric Network

• The network layer provides users with

named content, instead of communication

channels between hosts

Advantages

1. Native content-routing

2. In-network caching

3. Simplified support for mobile, multicast and

peer-to-peer communications

4. Support for time/space-decoupled model of

communications, including Pub/Sub

• “pieces” of network can operate

autonomously (e.g. sensor networks,

social gatherings, trains, planes, vehicles)

5. Content-oriented security model; securing

the content itself, instead of securing the

communications channels

6. Per-content quality of service differentiation

and access control

7. Network awareness of transferred content

• better control on information transfer and

related revenues flows

8. Simplification of network design and

operation, integrating diverse functions,

avoiding patches and stopgap solutions

A common container: the Versatile Digital Item (VDI)

• A standard–based (ISO-MPEG), self-contained,

“all-inclusive” data unit

• A container for any kind of digital data, including media,

representations of people and virtual or physical objects (Real

World Objects - RWOs)

• Binding of:

• data =resources: other VDIs, audio, images, video, text,

descriptors of People, descriptors of RWOs, etc.

• meta-data=meta-information describing the content of the

item; authentication and protection; rights to use the item;

expiry date (supporting “digital forgetting”)

• VDIs have a unique identifier, are handled by a Pub/Sub

middleware and distributed by an Information-Centric network

• Search engines can exploit VDI description and metadata for indexing

Functionality/advantages for users

1. Create a VDI, defining related licenses and rights

2. Sign and/or encrypt a VDI

3. Search and Retrieve a VDI (with metadata easing semantic

searches and operation of search engines)

4. Publish a VDI

5. Subscribe to a VDI (meeting specified criteria)

6. Verify the authenticity of a VDI

7. Monitor the use of published VDIs

8. Communicate with owners of VDIs

9. Versioning a VDI and linking it to other VDIs

10. Update a VDI (e.g., my CV, parts catalogue)

11. Delete a VDI (digital forgetting and garbage collection)

CONVERGENCE: the demonstrators

Enhancing the Internet with an information-centric, publish-subscribe

service model, based on a common container for any kind of digital data,

including representations of people and Real World Objects

Demonstrator of the Integrated

Photo-Retail Application

Demonstrator of the

Information Centric Network

The Integrated Photo-Retail scenario demonstrates sharing

of VDIs among different Applications, embedding

information about Real World Objects (cameras, cell

phones, lens, etc…).

Users and Applications interact via Publish/Subscribe

actions. Demo users take the roles of Content Creator (a

photographer), Content Consumer, Manufacturer and

Retailer:

• Users login via Single Sign On with a Secure Token

• Product-VDIs are created by means of a Manufacturer

Application and describe e.g. cameras and lenses

• Offer-VDIs, describing special offers to sell these

products, are created by means of a Retail Application

• A Photographic Archive Management (PAM) Application

includes automatically-generated camera information

from EXIF, such as camera model and lenses, within

Photo-VDIs uploaded by the Creator

• After publication, CONVERGENCE can associate Photo-

VDIs with Product-VDIs for camera and lenses

• Consumer browses images with the PAM Application. The

PAM subscribes by itself to Offer-VDIs of equipment (e.g.

for the lens used to shoot the photo). Matching Offers are

shown to Consumer, who can then buy Products

CONVERGENCE “BUS” The demonstrator shows the functionality of a complete

CONVERGENCE system composed of:

1. The CONVERGENCE Information Centric Network

(CoNET) deployed on 20 PlanetLab nodes and

emulating a scenario with four ICN Autonomous Systems

(World, Peru, France, Italy).

2. The CONVERGENCE Middleware (CoMID) providing

applications with content-based publish-subscribe

services.

3. A CONVERGENCE Application for the dissemination of

video materials by means of the pub/sub paradigm.

Demo users take the roles of Publisher, Subscriber and

Content Distribution Provider, interacting with the

CONVERGENCE System via a Web Interface:

• The Publisher injects video content in a Repository

• The Subscribers express their interest, are notified of

matching video content and play the published video

• The Content Distribution Provider monitors the usage of

its Repositories and may replicate the content in other

Repositories

• The CONET routing plane routes-by-names video

requests towards the closest repository

• The CONET in-network caching limits inter-AS traffic
