- NIIT has better access to NWFP than does IIU or PERN. Possible reason could be ping unreachability. Unreachability is higher from IIU (46.25%) and PERN (39.17%) as compared to NIIT (36.39%). Detailed stats here. Throughput is higher from IIU and PERN to NWFP; 5218 kbps and 7048 kbps respectively, whereas throughput from NIIT falls to 2259 kbps. Detailed stats here.
- PWR-PWR and PWR-NWFP is good (green). PWR and NWFP belong to PWR (Peshawar) region.
- TAX to LHR is better than TAX to LHRISB:
- pinger.uettaxila.edu.pk (121.52.150.164) is on PERN network. Most nodes in Lahore are on PERN network: LSE (111.68.102.40), pinger.lcwu.edu.pk (111.68.103.135), pinger.nca.edu.pk (111.68.102.69), pinger.lhr.nu.edu.pk (111.68.102.125), pinger-itc.pu.edu.pk (111.68.103.29) and pinger.uet.edu.pk (111.68.102.14) but about half of the nodes in Islamabad such as SEECS maggie1, maggie2, monitor nodes and COMSATS are not on PERN network. However this doesn't fully explain why this is so.
- Another inconsistency shown by stats is in inter-city routes. PERN network (shown above in Map of PERN2) is not fully deployed. In fact most of the inter-city routes aren't yet deployed. This is confirmed by the following two traceroutes of February 2, 2011. Traceroutes show that routes use public network (pie.net.pk) of Rawalpindi and Lahore telecom exchanges.
