We have just completed adding Local Breakout to an existing Client’s remote site that was already using Juniper WXC devices configured with multi-path, to provide more bandwith, which in turn allows us to improve the end User experience. The addition of local breakout provides a solution for directing non Corporate based web traffic directly out to a locally hosted cloud based web proxy.
High level architecture.
What Is Policy-Based Multipath Technology?
If a pair of WXC series devices has two possible WAN paths between them, you can designate one path as the primary and the other as the secondary. You can then route application traffic to the primary or secondary path based on the performance requirements of the application and the actual performance of the path.
How Does Multipath Technology Work (Basic)?
With Juniper’s Multipath solution, each WXC series device has a primary and a secondary IP address. Two optimized tunnels are established between the WXC series devices using their primary and secondary IP addresses. Each tunnel is routed by the network infrastructure via a specific path.
New flows are identified as an application (such as email, common Internet File system, etc). Each application belongs to a traffic class (such as business critical or default). Each traffic class is configured to use the primary or secondary optimized tunnel.
What is local internet breakout?
Internet breakout is a method of routing traffic directly out to the Internet from the local router, rather than back hauling the traffic. To enable local breakout there are a number of configuration amendments to routing and switching infrastructure. The benefits of using this technology are happier end Users!
