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.

Virtual Venues Client
• What can be done:– Sharing Data– Shared Applications– Integration with existing
Scheduling software
• Applications:– Distributed PowerPoint– Shared Web browser– Whiteboard– Shared Desktop Tool– Shared Visualization Tools
• Integrate legacy workflows– APS SER-CAT
• Beam line Controls• Data Processing• Data Analysis• Archiving/Reporting
– Fusion Collaboratory• Collaborative Control
Room
– Atmospheric Science• Shared Data Visualization

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
MSR SciData Workshop May 25, 2004
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
MSR SciData Workshop May 25, 2004
AGTk 2.2 3.0
• Network Services– Example Services
• Node Management• User/Venue Services• Chat Improvements• Firewall optimizations• Port to OS X• “Community Service”
• Operators Interface• New Node Services
– High Quality Video– Display (with layout)– Camera Control
• Interoperability– SOAP (ZSI, Apache)– Language (java, C/C++)
• Grid Data Integration
MSR SciData Workshop May 25, 2004
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
MSR SciData Workshop May 25, 2004
Roadmap II: AGTk 3.0 ???
• Grid Compute Resources
• Authentication Flexibility
• Certificate Authority Services
• Application Integration (for specific targets)
• Workflow Support
• Application Hosting Services
