Internet Connectivity Revived

The internet is one of the lifelines for us in today's world of advanced technology. It is a pillar that we all strongly contingent on to address a plethora of our daily concerns.

It has evolved into a necessity, which if deprived, leads to a void in our lives that is irreplaceable by any other means.   
After months of crippling internet connectivity at NITR, the authorities have finally awoken to a much awaited solution to this widely affected issue. But what exactly was the problem that took such a while to be addressed? For how long are we relieved with a stable and decent internet connection? To answer these queries, we got into a conversation with Prof. AK Turuk, the head of the Computer Centre, to clear the air on the subject.  

MM: What problem was detected in the internet connectivity?
AT: It was the massive problem of flooding. Earlier, we would detect these flooding ports manually, which is a tedious job. Now, we have acquired a trial license of NMS (Network Management Services) software which can easily detect the port from which flooding is coming and that specific port can be blocked. Blocking of these ports drastically improves the performance of the internet speed.
The second problem was with the usage of the memory. If the memory usage becomes more, particularly the firewall memory, the internet connectivity is dramatically affected. We talked to the Cyberoam officials and they too confirmed the problems with the memory usage issue. Currently we have installed two Cyberoam boxes in active mode to facilitate the high user demands. The Cyberoam officials have detected voluminous traffic that the software is unable to handle. A detailed report of the same is yet to be obtained from the Cyberoam officials.

MM: Has the NMS software already been installed?
AT: We had already floated a tender long ago to procure the NMS software. Right now, we are running on a trial version of the software which has a validity of 3 months.

MM: What is the reason for the improved internet connectivity at present?
AT: The two reasons are the trial version of NMS installed in the system and the second Cyberoam box in function.

MM: Is this a temporary solution or a permanent one?
AT: At present, this is a temporary solution to the problem. We are trying to figure out a permanent solution to the issue. The second Cyberoam box installed is on a trial license and is due to expire in a week's time. We shall hold discussions with the technical people of Cyberoam and devise a permanent solution to the problem.

MM: Since Cyberoam is not equipped with handling such a voluminous traffic, is it not possible to obtain different software?
AT: There are two options. First is to change Cyberoam and get another box which can handle more traffic than Cyberoam. But that option is becoming costly for us at the moment, being estimated at around 50 lakhs.
The other option is to go with Cyberoam software that is presently installed, one of whose boxes expires next year.
"We are planning to get hardware instead of software to handle the internet connectivity. Hardware is four times faster than software and can handle traffic much immense than software, but is a costlier setup."
The administrative decision to be taken is whether to continue with Cyberroam and get the license renewed or dump the Cyberroam box and go with a new product.

MM: What happens if NMS detects flooding and blocks a port?
AT: Once the port is blocked, the internet access to the user is suspended. The user who gets blocked will receive a webmail stating the same and can get his internet connection resumed the next day.
