High availability IPv6 networking

Allied Telesis high availability solutions work equally well for IPv4 and IPv6 networks, and even networks that are in transition using a combination of both protocols. To provide a highly resilient solution requires that the infrastructure and features of the networking equipment, as well as the traffic passing through the devices, is well managed and can survive any disturbance or interruption to normal network connectivity.

With most networks making use of routing protocols, it is imperative that the dynamic nature of this traffic management is handled in any fault situation to ensure continuous online resource access is not compromized. Adding dynamic routing resilience to high availability network design guarantees superior performance.

Two key technologies from which we have built the high-availability IPv6 solution are Virtual Chassis Stacking (VCStack™) and graceful restart (also known as non-stop forwarding).

VCStack provides a network infrastructure with no single point of failure that automatically responds to any connectivity loss. Graceful restart manages changes in the network topology to keep active paths through the network available, and minimize downtime that might otherwise be experienced when a network switch is taken offline.

We can take a closer look at these two technologies.

Allied Telesis provides a completely resilient solution for next generation networks – minimize downtime and maximize access to online resources and applications.

Virtual Chassis Stacking (VCStack)

Using VCStack at the core of your network allows multiple switches to appear as a single virtual chassis. This virtual chassis acts as a single switch, simplifying management.

With VCStack, Allied Telesis now provides a truly resilient network. In normal operation, all bandwidth and all routing power in the network are fully available for use all the time. If a link or device fails, some of the bandwidth or forwarding power will be lost, but the network will still be fully operational and all remaining resources will continue to be fully utilized.

IPV6 specifications

Allied Telesis is a leader in providing advanced networking solutions, and its implementation of IPv6 technology showcases their commitment to future-proof networking. With the exhaustion of IPv4 addresses, the transition to IPv6 is more critical than ever. Allied Telesis's IPv6 solutions offer an array of features, technologies, and characteristics designed to enhance connectivity and performance in today's digital landscape.

One of the standout features of Allied Telesis's IPv6 implementation is its robust support for dual-stack networking. This allows organizations to run both IPv4 and IPv6 simultaneously, ensuring seamless communication as they transition to the newer protocol. This dual-stack capability is essential for businesses that need to maintain legacy systems while adopting modern internet standards.

Additionally, Allied Telesis devices are equipped with advanced routing protocols that support IPv6, such as OSPFv3 and RIB (Routing Information Base). These protocols enable efficient routing and management of IP addresses across large networks. This enhances routing efficiency and optimizes network performance, crucial for enterprises operating in a high-demand environment.

Security is another vital aspect of Allied Telesis’s IPv6 features. The technology includes native support for IPsec, which provides encryption and secure tunneling capabilities for data transmission. This built-in security feature ensures robust protection against potential threats, giving organizations peace of mind as they expand their IP infrastructure.

Another important characteristic of Allied Telesis's IPv6 technology is its simplified network management tools. The implementation of IPv6 promotes stateless address autoconfiguration (SLAAC), allowing devices to configure their own IP addresses automatically. This reduces the administrative burden on IT teams and decreases the chances of address conflicts within the network.

Moreover, Allied Telesis's IPv6 solutions are designed with quality of service (QoS) in mind. This is particularly crucial for organizations that rely on voice and video over IP applications, where latency and packet loss must be minimized to maintain a high-quality user experience.

In conclusion, Allied Telesis’s IPv6 technology is a comprehensive solution that combines dual-stack support, advanced routing protocols, robust security measures, simplified management, and QoS features. These aspects make it a compelling choice for organizations seeking to upgrade their network infrastructure and embrace the future of internet connectivity. With Allied Telesis, businesses can confidently transition to IPv6 and unlock greater capabilities for their networking needs.
