Introduction

• Both the architecture and the engineering processes of the Internet no longer suitable

• We want to bring innovation back into the network

• Some technical issues to deal with:– Can we cope with the massive number of

communicating things?– Separation of naming and addressing

• Policy and governance

• We need a holistic global approach – 4WARD Project

4WARD Objective

• To increase the competiveness of European network industry

• To improve the quality of life for European citizen– By creating a family of dependable and interoperable

networks providing direct and ubiquitous access to information

• To make the development of networks and networked applications faster and easier, leading to both more advanced and more affordable communication services.

• 4WARD takes a “clean slate” approach

Deriving 4WARD Requirement

• It is important to identify the requirements that consistently should cover the whole 4WARD approach to a Network of the Future

• Requirements Analysis Process

23年 4月 20日 MMLAB 7

Requirements Analysis Process

1. Starting Point – overall 4WARD mission statements2. Stakeholders are identified

– Technical• Network architects, planner, equipment vendors,

operators– Non-technical

• Customers/users– Human users, Business and private users, Content

Producers, Advertisers

• Legal agreement bodies– Regulators (national, EU)– Legislator– governance

23年 4月 20日 MMLAB 8

Requirements Analysis Process

3. Concerns– The purpose or missions of the system– The appropriateness of the system for use– Feasibility of constructing the system– The Risk of system development and operation– Maintainability, deployability, and evolvablility

4. Scenarios• Use case, Growth, Exploratory

5. Requirements6. Views

– Representation of a whole system

Non-technical Aspects

• Usage and Services– How will users benefit from the technology advances of

4WARD• E.g. Shall support

– existing as well as emerging business models– service provider requirements for managing their

operation– mass market customer requirement

• Socio-Economics– Services will become ubiquitous, will be underlying to all

social and economic infrastructure• E.g. Shall support safety-critical applications

• Policy, Governance and Regulation

23年 4月 20日 MMLAB 10

Technical requirements

• Primary concern of 4WARD– Information-centric network

• Users only need to be aware of the information identifiers and not of the location of the information

– Future Internet connectivity• Should always available

– Interoperability• Assure the interoperability between different

architectures, different domains– Security

• Privacy, lawful interception

Summary

• In 4WARD, technical requirements are defined• These overall requirements will be transferred

into various specific architecture designs, concepts and realizations, highlighting different views of the respective work packages or technical themes according to the delivery plans.

• Also, these requirements will server as a useful reference for other research groups
