P2P progress
by Seok Bae Yun 12 Mar '12

12 Mar '12

All, Here is progress update. I wrote a draft document about the security verification methodologies of authentication and authorization model. Dr. Brooks is reviewing it. Maybe that needs to be reviewed with Dr. Brooks back and forth. This week I will add the part of performance verification methodology into the document. For the next meeting, do we need to make a call to this number next week? 505-844-9545 or is it for the Thursday meeting? Best regards, Seok Bae Yun

Call cancelled today
by Curry, Matthew Leon 12 Mar '12

12 Mar '12

Lee has cancelled the call, as someone on the call was in a noisy environment and would not mute their phone. It is unproductive to have the call when it is difficult to hear and understand one another, so we all have to cooperate and mute our phones when we're not speaking. Sorry to those of you who were being considerate, we'll try again next week. Matthew
