Communication Service Provider DNS Solutions
Ensure the security, reliability, and scalability of your subscriber services
The growing number of devices, applications, and services on the Internet is making it increasingly difficult for communication service providers (CSPs) to deliver a quality user experience for subscribers—and it isn’t just a bandwidth issue. DNS is one of the key elements in the network infrastructure that delivers content and services to the user, managing a distributed architecture to ensure high availability and fast response times. Because of its critical role, DNS can be the target of attacks that flood DNS servers to the point of failure. This vulnerability threatens the security, reliability, and scalability of the DNS infrastructure and the ability of the CSP to ensure a high quality of experience (QoE) for subscribers.
F5 provides a more intelligent way to respond to DNS queries. F5 DNS Services distribute subscriber requests and application services based on business policies, data conditions, and application performance. Built to handle the unique demands of the CSP infrastructure, the F5 DNS solution can help you dramatically improve the scalability, security, and reliability of the services you provide.
Why do I need a carrier-grade DNS solution?
Business benefits of using F5 for carrier-grade DNS:
High-performance and available DNS.
F5’s high-performance, chassis-based systems deliver up to 15 times the volume of requests handled by traditional DNS servers and ensure high availability.Superior security.
F5 helps you mitigate the effects of DoS and DDoS attacks without limiting performance or scalability.Reduced complexity and costs.
