What happened to routing?

[Anurag Bhatia]

My latency to Google 8.8.8.8 via my primary ISPs interconnect in Noida:

ping -c 5 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
64 bytes from 8.8.8.8: seq=0 ttl=60 time=3.792 ms
64 bytes from 8.8.8.8: seq=1 ttl=60 time=4.049 ms
64 bytes from 8.8.8.8: seq=2 ttl=60 time=3.876 ms
64 bytes from 8.8.8.8: seq=3 ttl=60 time=3.937 ms
64 bytes from 8.8.8.8: seq=4 ttl=60 time=3.854 ms

--- 8.8.8.8 ping statistics ---
5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max = 3.792/3.901/4.049 ms

This is up from 2.8ms normally due to fibre issue between Rohtak and Bahadurgarh and actual routing here is: Rohtak > Gohana > >>> Sonipat > Noida > Delhi > Noida due to ring design, layer 3 termination etc. But anyways that should give you the idea.

Nice, which ISP is this btw? I don’t know ISP options in Rohtak apart from big 3 (Jio, Airtel, BSNL). Neither have a latency this good.

Meanwhile I get 9-10ms on Airtel in Chennai to their own server

@RKhan21 just Jio and Airtel things.

It’s result of real world limitations. These networks cannot put small routers everywhere. Beside the cost of routers, IPv4 nating want to work well. Anyone operating network at this skill would have similar issue.

@Anurag Bhatia But I've seen that Airtel in Hyderabad has 1-2ms ping to their own server atleast.

It’s a custom set up. I use circuits from one provider to reach a friends pop in Noida. Then I transit out of friends pop. So technically it’s mix of both of these networks - one for physical last mile and middle mile till Delhi and other beyond that. Most of providers working out at layer 1, surprisingly do not have any branding or website etc

Do you mean that kind of latency from Hyderabad to Hyderabad? If so, it’s fine and make sense. Please understand that point I am making her is that traffic from within Telangana would often hit Hyderabad. And hence, calculate latency based on 1) distance to Hyderabad or whatever large city, State capital is. And 2) routing from that city to other large city.

It’s similar to say air travel. You can travel from Delhi to Mumbai directly. But you cannot travel from Jaipur to Tirupati. You would eventually go via large city.

What I meant is airtel here in Chennai has high ping to their own server which is very unusual for a fiber network
