Myanmar-based Internet service provider (ISP), RedLink Communications, runs a high-performance application networking platform that is used by 250 employees and 10,000 customers. Such service provider networks are very diverse and often require different transition technologies to be deployed simultaneously.
As such, the ISP faced two critical issues within the organisation. Firstly, RedLink needed to look at IPv4 address scaling and exhaustion and ensure that all their future communication and connectivity demands can be met. Another concern was that the traditional network address translation (NAT) environment was also breaking many applications, which could impact the user experience.
To counter these issues, RedLink Communications deployed A10 Networks' CFN product line of Carrier Grade Networking gateways as part of its network upgrade.
The solution enabled RedLink to extend the lifetime of its current IPv4-based infrastructure, saving cost and gaining time to plan an IPv6 transition strategy. It was also able to preserve IPv4 addresses by centralising the public address resources, and sharing them across a large user community.
In a media statement, A10 said that the deployment of any transition technology needs to concurrently support the interplay between old and new technologies to allow for a phased transition; and this was a requirement that was met by the upgrade.
The CG-enabled solution offered advantages over traditional NAT operations. Besides a seamless experience, the carrier grade networking appliances facilitate future application development and allows for fair distribution of RedLink's resources across the user-base in accordance with its requirements. This helps to provide the users with more efficient log file size management.
"With the deployment of the CGN appliances, our network now has 10GbE fiber port connectivity. A10's Carrier Grade NAT (CGNAT) platform has helped to resolve concerns we had with IPv4 address scaling and exhaustion," said Myint Thein, Chief Engineer for RedLink Communications. "We are confident that all our future communication and connectivity demands can be met with the deployment additional CGN appliances in our network."
According to RedLink, it also intends to move to an LTE network in the future and to continue upgrading its network in the next two years taking advantage of the A10 CGN appliance's scalability and flexibility with the deployment of new technologies.
