1. BoF on A3 Appliance Aggregation Architecture
Dejan Milojicic
Hewlett Packard
Global Grid Forum 5, Edinburgh, July 23, 2002

2. Purpose of This BoF
Evaluate a proposal for a Research Group on Appliance Aggregation within P2P technical area
Bring GGF and P2P communities closer together
5/18/2019

3. Introduction IT appliances are penetrating daily life
cell phone, digital camera, watch, PDA, laptop, …
Rather than helping, IT is becoming more complex
distributed data, resources, and I/O
hard to manage, use
privacy and security concerns
IT appliances designed & used like traditional ones
one function, isolated state, resources
however, IT appliances are connected, introducing: distributed state, shared resources, apps & functionality
Wearables: battle for the belt

4. Motivation Ownership of devices, appliances work only for me
Access any data/resource from any appliance
Use apps from any appliance
Perform tasks unaware of appliances, applications
Appliance ensemble
Levels of aggregation
Ways of using it
interaction of existing appliances
compose new appliances
performance

6. Scenario 1
Ensemble
Written notes
Aggregation
Scenario now for motivation purposes, rather than meat of talk…
Data Storage
Your appliances work together to help you achieve your task
Spoken notes/commands

9. Definition of Terms
Appliance: a (network) device able to aggregate with other devices; a smallest unit of aggregation
example: camera, PDA, laptop, watch, hotspot, etc.
!example: no communication
Ensemble: a group of appliances aggregated to perform a function greater than their parts
example: camera & PDA capture & annotate pictures
!example: fixed relationships (!ad hoc)
Appliance aggregation: multiple appliances operating as a single entity for a period of time
example: use another device’s screen; ensemble-wide app
!example: using predefined clusters
5/18/2019

10. Requirements Appliance discovery, identity, and communication
Secure communication channels between appliances
No trust boundaries within an ensemble
Access to aggregated resources of personal and environment appliances
Illusion of a “bigger” virtual appliance, consisting of aggregated sum of resources of individual appliances
Tolerance to temporary and permanent failures and disconnection of appliances in an ensemble
5/18/2019

11. Vision (where to) Perform any function using any IT appliance anywhere
5/18/2019

12. Mission (what and by when)
Devise an architecture of appliance aggregation in the next 2 years
5/18/2019

13. Purpose (why and for whom)
To improve access to data and services from any location using available IT appliances by wide population of people (enterprise, home..)
5/18/2019

14. Tentative Goals Devise best practices (6 months)
staged architecture (12, 24, 36 months)
standards (36 months)
working prototypes (6-36 months)

15. Related Work Pervasive computing visions Platforms Architectures
Academia: Weiser, Thackara, Oxygen, Norman, Satya, …
Industry: Digital Jewelry, wearable computing, storage
Platforms
UPnP, Jini, one.world, other academic/industry efforts
Architectures

16. Summary Many separate technical solutions already exist
Extraordinary opportunity for innovation, standards
Orthogonal to traditional GGF topics
Potential interest by academia and various industries
Bringing P2P closer to GGF
