Internet Service Provider plays a major role in this internet-based world. CORUS INFOTECH support our clients to build their infrastructure to provide internet services to customers in a good quality. We prefer a scalable and cost effective solutions which never compromise quality.
Our DNS Server is an open-source tool that can be used for self-hosting a local DNS server for privacy & security. It works out-of-the-box with no or minimal configuration and provides a user-friendly web console access.
Nobody really bothers about domain name resolution since it works automatically behind the scenes and is complex to understand. Most computer software uses the operating system’s DNS resolver that usually queries the configured DNS server using UDP protocol. This way works well for most people but, ISP can see and control what website you can visit even when the website employs HTTPS security. Not only that, some ISPs can redirect, block or inject content into websites you visit even when you use a different DNS provider like Google DNS or Cloudflare DNS. Having our DNS Server configured to use DNS-over-TLS or DNS-over-HTTPS forwarders, these privacy & security issues can be mitigated very effectively.
With a fully configurable DNS server running on your local server, you can configure not just simple A records (for IP address) but, also configure other types of records like CNAME or MX, etc. This allows you to have more control and power when you want to do testing that simulates the exact configuration that you have running on production.
CORUSvBNG powered by TheRouter
This is an application that successfully implements Network Function Virtualization
concepts. This vBNG is primarily designed to solve problems facing broadband Internet
access providers and digital services operators who work directly with significant amounts
of subscribers and process large volumes of traffic at speeds from 10 to 80 Gbit per second.
The use of modern approaches and best algorithms allows our vBNG efficiently use
affordable and widely available x86-based server equipment thereby replacing high-cost
proprietary equipment.
Benefits
usage of standard x86 servers
• sufficient cost cutting (up to -70%)
• simplified delivery and deployment
• improved flexibility and scalability: scaled up and down elastically
• pay-as-you go model: you purchase the only product and volume of service you need

Bison Router software-based, or virtual BNGs are designed to deliver unmatched performance and scalability on low-cost white box servers. It brings the flexibility and agility operators need to quickly address opportunities in today’s changing market defined by an ever-increasing demand for bandwidth and a growing complexity of application handling. The BNG establishes and manages subscriber sessions by acting as the authentication point through which subscribers connect to a carrier’s broadband network. It aggregates subscriber traffic from the access network and handles several important management functions, including authentication, authorization and accounting , IP address assignment ,Quality of service (QoS), and Policy of management.
