Blogspot-Airtel problem - Data Communication practical analysis

Blogspot-Airtel Problem: Our Analysis

February 12th, 2011

By Anurag Bhatia

Leave a commentGo to comments

There have been lot of news about Airtel blocking blogspot today.

Well, did they really blocked it?

It’s very hard to give a direct answer to that. Firstly, I believe that Airtel must have not intentionally blocked whole blogspot.com domain name (well they are a big ISP, and I don’t think they will go that kidish!).

What could be problem?
To understand that – let’s break Internet connection into parts as per TCP/IP model

1. Physical layer + Data Link layer on bottom most

2. Network layer – DNS, Internet routing, BGP stuff

3. Transport + Application layer – web browsers, scripting, web servers, data rendering etc

Well – Physical and data link layer were not really issues – since people who were having issues must be on a system “connected” to Internet, and same with Google’s Indian mirrors (which are usually on datacenter with redundant physical links)

Next, we see #2 Network layer – yes there can be issues here. And since people were not able to open website at all, rather then getting error 404, 500 or say a broken site – there was not really issue with Transport + Application layer.

So what can be possible issues at Network layer?

Broadly speaking – it consists of two parts – DNS and Internet routing.

DNS, as I explain is last post simple resolves www.blogspot.com into IP address. I have seen a few traceroutes on Internet – and they are all timing out after a certain IP address. From that it clearly seems issue was not on Airtel’s DNS servers. If it was issue at DNS servers – then would be getting – “Name not found” error in web browser, rather then “request timed out”.

This was surely issue which we can say under “Internet routing”. That is – when you get IP address of www.blogspot.com – next, you try to connect to that machine to create a “socket connection”.

In order to find the “Physical network location” of server, ISP’s core routers use protocol called BGP – Border Gateway Protocol. This helps in creating a “path” between your system and data packets flows above it.

Right now it seems like issue is resolved. Well here’s one traceroute from popular website –IBN Live

So, we see that things started timing out at 7th hop. Last hop which responded was node with IP address – 203.101.83.197 Well, this IP address belongs to Autonomous System 9498 which is of Airtel. This means till hop 6th we were still on Airtel’s network.

Next, here’s one of traceroute taken at evening when blogspot.com was working fine.

If you observe, hop 5th here is same as hop 6th in last traceroute which was last node which responded – 203.101.83.197

In this working scenario – we see two hops are:203.101.100.210 & 72.14.216.229

First IP belongs again to Airtel, and next one is of ASN 15169 – belonging to Google. So clearly on 7th hop we are on Google’s network.With that all we can say is – there was certainly problem between either of two networks – Airtel or Google. The point from where they “peer” that is “interconnect” seems to be not available during daytime.

From traceroutes we can’t directly predict if it was just Airtel’s network or Google’s network or could be a router inside Google’s datacenter which links with Airtel’s domestic backbone. It can be glitch on BGP routers of Airtel or Google (in case of Google – the one which is specifically used in link with Airtel) as people on BSNL didn’t reported any such case.

If you are still having trouble in accessing blogspot.com – please do send us traceroutes and we would be more then happy to investigate further.

To do a traceroute on windows machine, just click on Start > run > (enter) cmd.exe
Next, in command prompt type – tracert blogspot.com and then send us the screenshot.

Address calculation of 2D array

The home work given by Prof.R.K.Selvakumar on DCA in C++ Subject on 02.09.2012

The answer is :

CALCULATION OF ADDRESS IN 2D ARRAY

Date : 02.09.2012

Definition 2 D Array: A 2D array is an array in which each element is itself an Array.

For instance, an array A[M][N] is an M X N matrix.

Where : M = No. of rows

N = No. of Columns

M X N = No. of elements.

Implementation of 2-D Array : There are two way to store elements of 2-D array in Memory

1. Row Major - Where elements are stored row wise.

2. Column Major. Where elements are stored Column wise.

Finding The Location (address) of an element in 2-D array:

CASE : 1 . When elements are stored row wise:

Case 1.1 When lower bond is not given.

A[M][N] or A[M,N]

Address of A[I][J] or A[I,J] = B+ W[N( I)+J] .

M= Total No of Rows

N= Total No of Columns

I = Expected row

J = Expected Column

W = size of each element in byte.

Case 1.2 When lower bound is given.

A[Lr…Ur][Lc…Uc] or A[Lr : Ur , Lc : Uc]

Address of A[I][J] or A[I,J] = B+ W[N( I - Lr )+(J-Lc )] .

N= Uc – Lc + 1 (Total No of Columns )

I = Expected row

J = Expected Column

W = size of each element in byte.

Lr = Lower Bound of row

Lc= Lower Bound of column

Uc = Upper Bound of column

CASE : 2 . When elements are stored column wise:

Case 2.1 When lower bond is not given.

A[M][N] or A[M,N]

Address of A[I][J] or A[I,J] = B+ W[M(J)+I] .

M= Total No of Rows

N= Total No of Columns

I = Expected row

J = Expected Column

W = size of each element in byte.

Case 2.2 When lower bound is given.

A[Lr…Ur][Lc…Uc] or A[Lr : Ur , Lc : Uc]

Address of A[I][J] or A[I,J] = B+ W[( I - Lr )+M(J-Lc )] .

M= Uc – Lc + 1 (Total No of row)

I = Expected row

J = Expected Column

W = size of each element in byte.

Lr = Lower Bound of row

Lc = Lower Bound of column

Uc = Upper Bound of column
