9. 9 Why do we need PAG? AGSC Surveys 2006 and 2007 Common Problems Difficulty connecting to a venue (e.g. firewall or multicast problems) not being a multicast site …switch to the unicast bridge …” AG Firewall rules and Muilticast / Unicast are a nightmare – These need to be simplified and made more reliable Many partners have problems connecting because they are setting up temporary nodes. Most of the problems are due to inexperience with NAT (port forwarding) & firewall configurations

10. 10 Why do we need PAG? AGSC Surveys 2006 and 2007 Requested Improvements More reliability Greater coverage of Access Grid across institutions that do not currently have it Speed of the venue client Make it more user friendly …integration into portals … The AGSC should work towards providing training and advice for user managed desktop access to the system Increase in use of the personal access grid

11. 11 Why do we need PAG? AGSC Surveys 2006 and 2007 Comments Generally a lot of time is spent configuring the software … …Many systems exist for supporting web seminars … the potential of the AG in this respect seems to have been ignored. It needs to be as easy to use and reliable as any of the commercial video conferencing software you can buy. We only use personal AG, which is a much better option for getting people interested in and using the AG … I have to phone from China because my student didn't manage to install the AG S/W and get it working If I could connect to some meetings from the desktop, I would use the AG system more The process of configuring a personal node seems far more troublesome / complicated than it should
