Hi, Xu
I myself agreed, these input from Howard are very helpful(for me, too).
For your information, I'm never in a position against Howard's post.
I am one of his admirers. I always appreciate his insightful posts with great p
leasure.
But I was just wondering how far we have to go into detail of networking protoc
ols.
I'm constantly in a big fight between curiosity for the further research and la
ck of time given to me.
So for me it's always difficult to decide when to stop digging further.
I just wanted to get some advice about this. And I think his reply was more tha
n enough for this.
Thanks Howard and all again for sharing your great thoughts with me.
Jaeheon
