Internally, Jetty manages the HTTP Upgrade to WebSocket and migration from a HTTP Connection to a WebSocket Connection. and then next message starting from should be read by Netty server. Server A sends its ipv6 link local address with its zoneid in connector to server B in form - ipv6-server-A-address%zone-idA 2. The main advantage of Netty over simply reading from and writing to sockets using streams is that Netty supports non-blocking, asynchronous I/O (using Java's NIO API); when you use streams to read and write from sockets (and you start a new thread for each connected accepted from a ServerSocket) you are using blocking, synchronous I/O. In Hotspot JVM, there's a particular internal limit on the number of UDP sockets that can be open. I'm new to netty, but I've ran into two issues as seen in the workaround, while running the securechat(ssl) example of netty.
