AWS Global Accelerator now supports TCP termination at the edge for IPv6 traffic, in addition to IPv4 traffic. TCP termination automatically improves performance for workloads such as API operations, file uploads, and HTTP workloads. Starting today, customers who use dual-stack accelerators can get the benefits of TCP termination at the edge for both IPv4 traffic and IPv6 traffic.
With TCP termination at the edge, Global Accelerator reduces initial setup time by establishing a TCP connection between a client on the internet and the Global Accelerator edge location closest to the client. Almost concurrently, a second TCP connection is established between that edge location and the application endpoint in the AWS Region. With this process, the client gets a faster response from the Global Accelerator edge location, and the connection from the edge location to the application endpoint in the Region is optimized to run over the AWS global network. Until now, customers using dual-stack accelerators could only get the benefits of this feature for their IPv4 traffic. With this release, dual-stack accelerator customers get the additional throughput improvements for IPv6 traffic, as well as IPv4 traffic. This new feature incorporates the TCP optimizations that have been covered in this blog.
TCP termination at the edge for both IPv4 traffic and IPv6 traffic is enabled by default for all dual-stack accelerators and is supported at no additional charge. To get started, visit the AWS Global Accelerator website and review the documentation.
