This is a significant improvement in terms of average RTT, packet loss, throughput and IPDV . However improvement in Ping Unreachability is lesser than expected.
PERN PoP Islamabad to UETTAXILA
Considering that monitor.niit.edu.pk is not a pern node, we tried to analyze the performance of UET Taxila from Pern PoP Islamabad node.
...
Metrics | 1st Feb-2nd Mar | 3rd Mar-27th Mar |
|---|---|---|
Average RTT (ms) | 84.62 | 44.38 |
Packet Loss (%age) | 3.68 | 1.23 |
TCP Throughput (Mbps) | 1.4 | 4.4 |
IPDV (ms) | 23.94 | 0.63 |
Suggestions from improvement:
Increased Link Capacity:
Reduced average RTT is a consequence of increased link capacity.
Unresolved Issues:
- From March 17th to April 15th there is no data collected from monitor.niit.edu.pk to pinger.uettaxila.edu.pk. Was there some holiday at UET Taxila that resulted in network shutdown?
- Dr. Anjum we carried out all the analysis on seecs (monitor.niit.edu.pk) to UETTAXILA (pinger.uettaxila.edu.pk) link. We all know that SEECS node is not on PERN. In that case is this analysis going to be acceptable to HEC? We haven't chose anyother node to analyze uettaxila because we do not have traceroutes from nodes other than SEECS. Also SEECS nodes are the most reliable nodes as Dr. Les says. (This reliability appears in smokeping graphs having lesser outages from SEECS than from other nodes.)
- From 25th April to 7th May, the Avg_RTT was lowered from 30ms to 5ms and resumed afterwards. I along with Dr. Les tried to figure out the reason but we still are unable to find one. Sir Anjum, Can you suggest any important clue that can lead us to the reason why Avg_RTT was lowered so much?
- Since Friday I am unable to load SEECS pingtable and the smokeping graphs from SEECS pingtable. I need them for analysis. Can someone get this resolved so that I can make report as soon as possible.
