So it’s like Mumbai-India-Reliance | Hong Kong-Reliance | Hong Kong - Tata | Chennai -India-Tata | Somewhere in middle-Europe | Johannesburg - Tata
Reasons for crazy routing
- Packets were taken from Mumbai to Chennai via Hong Kong!
- Reliance has direct connectivity* to Johannesburg, South Africa via SEACOM cable link from Mumbai.
Why packets were taken outside India? Because Flagtel AS15412 and Tata Comm’s AS6453 are pretty much isolated. They mostly peer at niXi via their regional ASN’s which are Reliance Infocomm AS18101 and Tata-VSNL AS4755 = Main Problem.
Why Reliance didn’t used SEACOM rather then handling packets to Tata at Hong Kong?
Simply because of destination. Destination network is Neotel which is subsidary of Tata and relies for almost all of it’s International bandwidth on Tata’s AS6453. We can see routes via AS18101 just terminate - thus no local connectivity option for Reliance to handle packets directly to Tata within India (avoiding extra round trip to Hong Kong). Apart from that it seems like Reliance has no nodes/PoP’s in Africa. I tried bgp lookups to lot of African ISP’s and most are via London because Reliance has no local presence in African market and hence Reliance connects to African Networks at London where most of upstream providers of African Networks meet. Apart from that SECOM does provides in-direct link between Mumbai & South Africa as SECOM ring which starts from Mumbai lands in Tanzania, and Tanzania is connected to South Africa via Mozambique. Have a look at SEACOM map below:
So what’s the real world effect of such routing?
I can see neotel.co.za is blocking ICMP pings. Let’s use other IP which is before firewall - 18.104.22.168 which replies to ping. Now round trip latency to this IP from Reliance Mumbai node is ~ 311ms.
This could be well under 150ms if a direct route is established because actual distance is near around 5000miles. We actually get such performance between Tata Comm (Indian PoP’s) to Neotel as Tata is routing traffic via Cochin PoP where SAFE cable lands.
Router: gin-mlv-core1 Site: IN, Mumbai - MLV, VSNL Command: ping 22.214.171.124 Sending 5, 100-byte ICMP Echos to 126.96.36.199, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 128/128/128 ms
With hope that eventually we will have better routing between Indian ISP’s time for me to get back to Java learning! (well Practical test a day after tomorrow!) :(
