Why not switch over to IPv6 internet?

Avatar

Infolink is the first Bangladeshi ISP to offer fully IPv6 supported internet services on a commercial basis in Dhaka

Your internet, like ours, uses IPv4 internet. IPv4 stands for Internet Protocol version 4, and it is widely used to connect network devices to one another. Each device uses a specific address, based on IPv4’s 32-bit internet address format.

Private and public internet addresses combined have a total of around 4.29 billion addresses, almost all of which are nearly exhausted. IPv6 addresses like 2001:0db8:85a3:0000:0000:8a2e:0370:7334 are based on 128-bit formats and can accommodate much more. More importantly, IPv6 is more efficient than IPv4.

The everyday private internet user in Bangladesh has either a 16-bit address, 192.168.0.0 – 192.168.255.255 or 20-bit address like 172.16.0.0 – 172.31.255.255 or a 24-bit address ranging from 10.0.0.0 – 10.255.255.255, all based on IPv4 protocols.

IPv6 was initially launched in 2011 to raucous praise, and the following year began to be adopted by most websites. It is estimated that all IPv4 addresses will be exhausted before 2018 is out.

The Dhaka Tribune made some inquiries and discovered that some of the most trusted broadband internet service providers (ISP) like Link3 Ltd, Mazeda Internet, Dot Internet, and Doze Internet do not provide IPv6 internet. A Doze representative said there are plans to begin shifting to IPv6 sometime around March. A Link3 representative said their addresses are a mix of IPv4 and IPv6.

Infolink BD is the first ISP in Bangladesh to commercially offer IPv6 internet. The Baridhara-based ISP offers connections to Baridhara, Banani, Bashundhara R/A, Dhanmondi, Gulshan, and Uttara.

Infolink offers internet packages for home and corporate internet. They offer real IP and dedicated bandwidth for every package. As Infolink is the first to offer IPv6 connection in Bangladesh, it is quite an endeavour to offer something the world is getting acclimated to gradually.

The pioneer ISP now looks to break new grounds with their services as they expand across the city.

InfoLink Launches IPv6 Commercially for the first time in Bangladesh

Avatar

Currently IPv6 is a top priority for the Asia Pacific Internet Society. APNIC reached the last /8 of IPv4 addresses in April 2011. Transitioning to IPv6 empowers the Internet to proceed to develop and empowers new, inventive administrations to be produced in light of the fact that more gadgets can associate with the Internet. You can try this link  ipv6test.google.com  to identify you can use IPv6 without any problem or not. In the whole world still today IPv6 adoption rate is less than 19% (ref 1).  InfoLink has been carrying out ipv6 technical trials in our production network for more than a year, and we’ve been working on IPv6 sending for more than 2 years. After such a variety of years of testing preliminary work, huge innovation venture, inward aptitudes advancement, and close coordinated effort with our goal accomplices, I am inconceivably satisfied to report that we’ve accomplished another basic turning point in our move to IPv6 we have begun the commercial pilot deployment of IPv6 (beta) to Bangladesh.

We’re presently one of the leading and first Internet Service Provider (ISP) in bangladesh to begin commercially launch IPv6. This is an awesome breakthrough inside our own company and as well as in the technology business, in the nation.

Finally, in the course of recent years of testing, advancement, and arrangement, Technical department of InfoLink have specifically had an impact in getting us to where we are today, regardless of whether that was creating specialized preparing, directing quality testing, conveying new rigging on our fiber spine, overhauling our get to organize, redesigning our back office networks, and endless different assignments both of all shapes and sizes.

Still there is long way to go. We have to build up our support hands to serve our customers with IPv6. We trust we will ready to conquer this challenge effectively.

As of now the most of websites don’t have IPv6 so it is getting difficult to forward our IPv6 User to peruse those site within best time and latency. Our team is already started to do research and development to make it more efficient.

Currently their is a common solution to do NAT in the system to avoid this problem. Those methodologies are probably going to bring about a few applications, (for example, some ongoing applications) breaking or appearing to be moderate. We are utilizing another way to deal with abstains from breaking or moderating applications and keeps up a superior and quicker broadband Internet encounter.

sooner or later, it’s far well worth noting that that is the start of pilot commercial marketplace deployments as opposed to complete country wide deployment. As such, it is possible that this will not be without technical bugs in the near term. Our focus is in identifying errors and bugs final IPv6 transition issues quickly and fixing them rapidly, so we can soon begin a complete national deployment.

I will like to Thank You to our Technical Team and everybody related to this task  who helped us lot with their knowledge and time. Special Thanks to APNIC to support with workshop and documentation.

Networking the largest shopping mall in South Asia

Avatar

Jamuna Future Park- by far the largest shopping complex in this subcontinent is to house more than thousand shops, premium outlets, showrooms and food courts. This enormous shopping district required connectivity for internal operations and functionality. Moreover the incoming crowd also required access to internet. But no other engineering firm had ever undertaken such a meticulous challenge.  It was ‘InfoLink’, a network engineering firm, who was awarded the contract to connect all parts of this gigantic shopping mall in a network to ensure that the entire network can be controlled and maintained from a single point location.
Since this was a mammoth project and no other project of this scale was ever implemented in this country hence InfoLink had a quite steep learning curve. InfoLink was to do three things:  1. Establish and install all a unified network. 2. Build and connect kiosk for visitors 3. Maintain and monitor the high volume network traffic and networking hardware.
Establishing a unified network was a multilevel work hence the crews where tasked in groups to finish the work within the deadline. There were many challenges to establish the network and install all associated hardware. Firstly the network needed to be centralized and controlled from one single point. To do so, all network hardware was specially configured. Secondly enormous space was required to be covered with fiber optic cables. And all cables required to be laid in the ceilings. Since the floor to ceiling height was 4.42 meter, specialized equipments were required to lay cables at such a height. Thirdly, the Wi-Fi devices, through which end users could access the internet, were extremely sensitive to dust. As the network development work done in the construction phase of the shopping mall, so the devices where frequently exposed to dust resulting malfunction. Lastly, the 410,808 square feet per floor made the footwork lengthy and time consuming. To address these challenges some changes were made in the plan. The device hanging problem was solved by rearranging the total device plan. The problem of backbone route was solved by creating a tunnel from the center to Jamuna Future Park pocket gate. A special cover was used for safety of Wi-Fi devices. High ladder was used for recovering dead cables and a special high elevation cart for installing the devices. Even after that some laid cables were not working properly. In that case, those cables had to be changed.
Kiosk/information booth was another part of the project. An electronic kiosk (or computer kiosk or interactive kiosk) houses a computer terminal that often employs custom kiosk software designed to function while preventing users from accessing system functions. Computerized kiosks may store data locally and offer the visitors data from the stored memory whereas the interactive kiosk fetched updated data from the main network storage in real time. Some kiosks provide free, informational public service, while other displayed advertisements. In total 25 kiosks are already deployed throughout the shopping complex.  But in long term a total of 900 units will be deployed. Each would carry advertisement that was related to Jamuna Future Park. To deploy such a large amount of foreign built kiosk was lengthy and expensive. So InfoLink came up with with a cheaper alternative. They suggested the Jamuna authority to go for locally assembled Kiosk. The kiosk outer-shell and CPU was designed and assembled locally. Only the touch-screen monitors were imported.  The software for the system was created by InfoLink software development team. Thus it marked the very first commercial deployment of Bangladeshi assembled kiosk.
Maintaining and monitoring the extremely high bandwidth-ed network was another part of the project. For this part of the project, monitoring cell/NOC (Network operations center) was put up and extra IP (Internet Protocol) was needed for covering all the merchant clients of the premises. For client billing InfoLink software team developed billing software which made total billing process accurate and secured.  Besides dedicated internet and shared intranet, the networking project also involved data connectivity services for CCTV connection, Branch connectivity, ATM connection, Wi-Fi service for floating customer and connectivity for mobile users using hotspot voucher card.
The future work of this project involves Wi-Fi network for the rest of the floors, deployment of 800+ new kiosks, enable hotspot voucher card with e-payment options etc. No wonder, projects of these sorts are the embodiment of engineering at its best.

Some facts & figures

  •  23,950 feet (approx.) 12 core Fiber optics used
  •  13,123 feet (approx.)  4 Core Fiber Optics used
  •  5,987 feet (approx.)  Cat 6 Shield cable used
  •  Total: 44,000 feet fiber optic cables used
  •  Total Core Capacity – 192 core and Scalable
  •  Backbone Capacity – 24 Core and Scalable
  •  Wi-Fi Coverage area– 350,000 Sq ft (Approx) ( Only 5th floor)
  •  At a time user – 300 Wi-Fi User successfully tested (supports up to 1000 users).
  •  Coverage area by Cable – 2,870,000 Sq ft (approx.)
  • Total number of Deployed Kiosk – 25
  •  Total Bandwidth Capacity inside Jamuna Future Park – 400 Mbps and Scalable.
