negative.code: The router routes traffic coming into Cloud Foundry to the appropriate component: usually, [Cloud Controller](./cloud-controller.html) or a running application on a [DEA](./execution-agent.html) node. The router is implemented in Go.
  Implementing a custom router in Go gives the router full control over every connection, which makes it easier to support WebSockets and other types of traffic (for example, via HTTP CONNECT). A single process contains all routing logic, removing unnecessary latency.
