Hi, I want to implement functionality that requires dynamically calculating RTT times for a TCP flow passing through edge router for Differentiated Services. I cannot make use of the TCP Agent's RTT data, since the node in question can be an intermediate node in a data path, without a TCP Agent associated with it. I want to calculate the RTT between that node and the destination, ignoring any previous nodes in the data path. So, I'm not sure how to solve the problem of calculating a TCP flow's RTT between a given node and the flow's destination. If anyone has any suggestions, the help would be appreciated greatly. Thanks, Xu zuhua |
