What is BDIX and what are the benefits of it?

BDIX is an IXP (Junction) where ISPs and other data service providers gets connected among themselves. It was established in 2004. It is a not-for-profit venture of the Sustainable Development Networking Foundation (SDNF) Bangladesh.

How IXP work

Why BDIX?

Internet Service providers used to get bandwidth from various upstream providers from various part of the world through- Submarine cable, VSAT, MicroWave Links etc. When data transmission from one ISP to another ISP was required – it used to go through the upstream providers round the world and come back to the destined ISP. I remember I had two different Internet  connection in my two PC and did a traceroute – and guess what!! There were 20+ nodes it had to pass from one IP to another. This created a lot of latency. Moreover, it was a very inefficient way of communication as data from one computer had to travel half of the world to reach the other one in my next room.

Some prominent ISPs in Bangladesh could well understand the fact and was eager to create an exchange among them so that local Internet traffic may routed locally. Year 2004 – United Nations Development Programme (UNDP) took the initiative through the project named “Sustainable Development Networking Programme” (SDNP). With the help of some individuals and ISPs BDIX was established.

From then more than 50 ISPs and Mobile/data operators got connected through BDIX.

 

What are the benefits?

Saves International Bandwidth

Well it is easy to guess what the benefits are. Local bandwidth remains locally. It means when one user from an ISP sends a files to another user in another ISP – the data does not need to travel out of the country. This keeps the International gateways free of data required to travel within the country. This saves the precious International Bandwidth.

Low Latency

Another benefit is – very low latency. In case of local traffic – data first goes to the BDIX from the source ISP and BDIX routes the data to destined ISP. This is only a matter of 3/4 hops/nodes. This means data travels faster.

High Data Volume

One major benefit is – a huge data can be transferred among the the local users. Since ISPs can get high bandwidth easily from BDIX.

Saves a lot of money to ISPs and End users

Low Cost + High local bandwidth – causing most of the ISPs to get connected to BDIX. BDIX bandwidth is way cheaper than actual International Bandwidth. Moreover, ISPs are creating local FTP server – where they store a bulk of movies, songs, games etc – which used to consume a lot of International Bandwidth. Now users download movies, songs, games etc – but it doesn’t use International Bandwidth keeping that one for much important uses. ISPs are now able to offer very low rate for Internet subscription as they can serve more people with less International bandwidth. End Internet users are getting higher bandwidth at lower cost.

New Features and Services

A lot of local sites have emerged with live TV facility, Local FTP servers, game servers etc. Volume of Data is not a problem if it remains locally.

 

Redundancy

We are developing our own local Internet through BDIX – and if for some reasons – International gateways are disrupted – we are less affected. Although International data transfer may be interrupted but local data communication will still remain running.

 

BDIX membership fee:

10,000 taka for 100mbps port

20,000 Taka for 1GB port.

SEA-ME-WE 4 Maintenance , 1-11 october 2010.

There will be maintenance work on SEA-ME-WE 4 starting from 01 October 2010 to 11 October 2010. As a consequence there will be two impact on us.

On 01 October, 2010 SEA-ME-WE 4 will be completely shut down starting from 22:00hrs BST for 4 hours (it may be longer according to our previous experience). Therefore, the internet will be unavailable for that duration.

From 02 October to 11 October 2010, the eastern side of Chennai will be down. During the restoration process  you may experience temporary latency and congestion to some destinations and intermittent inconvenience.

Why is VOiP illegal?

The government has been taking hard actions against some telecom operators who are purportedly using their internet facilitates for making international telephone calls. The operators are being fined millions of takas, their most valuable equipments are being confiscated and some are being banned from continuing such operations.

As a former Bangladesh Telegraph & Telephone Board (BT&T) official, I still do not understand as to why VOIP should be declared illegal in the first place. To put it simply, I understand VOIP is transmitting speech signal through the internet bandwidth. The operator is paying his rent for the internet band width. Also he is paying for the telephone line rent and call charges. Capability to transmit voice over internet band width is made possible through the advancement of signal processing technology. Why should someone be punished for using higher technology?

I recall when in the early 1980’s fax machine was introduced, BT&T used to charge an additional amount of Tk 10,000/- per fax machine. By then I left BT & T and used to have heated argument with my friends in the BT & T top management about the matter. They introduced this charging system only because they found an extra income source without contributing anything.

Today, VOIP is declared illegal as BT & T is being unable to provide cheap service which the IP service providers are contributing. If BT & T is loosing revenue because of VOIP use by the internet operators, then it is BT&T’s fault. It is like punishing a motor bike rider by a bullock cart driver as the latter cannot catch up with the former. It is single stupidity and wrongdoing by someone who is short of in knowledge. I like to ask the authorities concerned to come clean and prove that VOIP is illegal because it is harmful to the people in the way toxic drug import is illegal because it harmful to national health. Following a bad law, even if it is a law, is harmful to the nation in the long run.

I call for a national debate and let the authorities concerned defend themselves to prove what they are doing by declaring VOIP “illegal” is right.
