Access Grid Vision
• To create virtual spaces where distributed
people can work together.
• Challenges:
– Globally Distributed Participants
– Distributed Resources:
• Computational, Storage, Networks, and People
– Coordination, Scheduling, Trust
– Heterogeneous Collaboration Resources
• Solution:
– Deploy a set of Collaboration Resources to serve as
the platform for building the rest.

Access Grid Security
• Public Key Infrastructure (PKI) based security.
• Each user, server, and service has an identity
cert
• Communications use SSL (via Globus Toolkit™)
• SSL provides
– Mutual Authentication
(each pair of peers knows the identity of the other)
– Confidentiality
• Authorization is difficult, so we make it easier

Crossroads
• Up to now we’ve been serving the AG
community (ourselves) exclusively
• The introduction of this technology can
revolutionize science, deploying into new
communities will change the social landscape.
• It’s time for the Access Grid to grow up.
• So how are we going to get there?
– Become a service organization?
– Abandon the software and move on?
– Adapt and evolve!

Application Deployments
• Integration with various user communities
– Existing AG Community
• 1000 public + 300 private: 1000 users
– Fusion Collaboration
• > 1000 (@ 40 institutions)
– ANL Advanced Photon Source CAT Teams
• 4000 users
– Center for Learning and Multimodal Communication
– ABC Collaboration (Surgical Teaching)
• Introduces new requirements and refinements of
existing requirements
• Increases User base

Toolkit Research Directions
• Deeper integration with Grid Computing
– Compute Resources, Data Resources
– Publish/Subscribe Service Models
– Peer to Peer Applications and Services
• Investigate much more interesting node
solutions
• Extending Security Work
– More Authentication Solutions
– More Authorization Solutions
• Engage new communities

Roadmap II: AGTk 3.0  ???
• Advanced Node Configurations
–
–
–
–
–
Support for more Active Spaces
Better audio environments, high quality video
Better media synchronization
Integrated instruments (telescopes, beamlines, …)
This will cost: Bandwidth
• Minimal Node Configurations
– Handhelds
– Set-top box configurations
• Advanced Collaboration Services
– Stream processing, modifying
– Data mining from Streams
– This will cost: Latency
