Hi Michael, I think networking technology of GHPN-RG's goal is not your mentioned technology of L4 layer. The networking technology should especially be underlying network technology of L1,L2 and L3 layer . But i am confused if we build a relationship between underlying network and grid applications,we can call that grid applications utilize networking features . Regards, Andrew.

Hi,

I also don't know why this group is so silent; I can only speak for myself: I'm too busy with too many things at the same time to discuss a lot here right now :( but I expect to be more active in a few months.

Regarding your question about Grid applications that require advanced networking features - I think that this is the wrong question to ask.

No multimedia application *requires* RTP, RTCP, SIP or DCCP (i.e. couldn't work without it).

Does this make these protocols useless? No: they enhance the situation, but you couldn't say that they are "required".

Same for Grids. Grid applications are typically written to work in the environment they are run - but that doesn't mean that it would be useless to enhance the network for them.

Cheers, Michael

Hi all, GHPN-WG is inactive for a long time .What's wrong. In addition to,i have a confused problem.One goal of the GHPN- RG is that advanced networking features that are not being utilized by grid applications. I could not understand entirely .Would you please give some examples of grid applications that require these advanced networking features.

Thanks in advance. Andrew.
