Hi, Thank your for your response. i have 2 questions: 1. can you explain the looping method that allowed you to reach 100GB ? 2. Alcatel-Lucent is routers are givven for research internationally ? or its locally? what routers we are talking about here and what link do they have? i appreciatre if you explain more how do these routers saturate 100GB.
