问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . I am working on getting the performance parameters of a tcp connection and one these parameters is the bandwidth. I am intending to use the tcp_info structure supported from linux 2.6 onwards, which holds the meta data about a tcp connection. The information can be retrieved using the getsockopt() function call

问题 I have two+ Android devices. I would like the devices to send instructions to the other devices using Wi-Fi Direct, while at the same time being able to access the internet via their cellular data connection. It seems that using the Wi-Fi Direct interface is being treated as the primary connection, disabling the other connections, just like how Wi-Fi disables the cellular data connection. How can I programmatically allow both to operate at the same time? Currently the Wi-Fi Direct receiver is

问题 I want to share some information between two classes (A and B), which are running in different java programs. Instead of writing a whole communication protocol I want to use the java build-in rmi classes for that purpose. Currently class B is able to run a method which belongs to class A remotely. Is it somehow possible to use the same "connection" within class A to call a method of class B? Otherwise I probably have to implement a second rmi service ... BR, Markus 回答1: If B implements Remote
