## implemented protocols
- WebSocket over TLS
- QUIC (with TLS)
- TLS over TCP
- TCP over IPv4 / IPv6
- UDP over IPv4 / IPv6
## build
```sh
$ cd xxx # xxx=wss, quic, tls, tcp, udp
$ go build
```
## usage
```
-c
client mode
-s
server mode
-i
sending interval [ms] *client mode only (default 1000)
-m
message to send (default "Hello XXX !")
-v
IP version *TCP/UDP only (default "IPv4")
-n
number of parallel streams *QUIC only (default 3)
```
## WebSocket over TLS
### server
```sh
$ ./wss -s 127.0.0.1:18433 +[master]
[echo-wss]2018/03/02 Listening on 127.0.0.1:18433 ...
[echo-wss]2018/03/02 Remote peer 127.0.0.1:50401 connected
[echo-wss]2018/03/02 Server: Got 'Hello WebSocket !'
[echo-wss]2018/03/02 Server: Got 'Hello WebSocket !'
[echo-wss]2018/03/02 Server: Got 'Hello WebSocket !'
[echo-wss]2018/03/02 Remote peer 127.0.0.1:50401 disconnected
```
### client
```sh
$ ./wss -c 127.0.0.1:18433 +[master]
[echo-wss]2018/03/02 Client: Sending 'Hello WebSocket !'
[echo-wss]2018/03/02 Client: Got 'Hello WebSocket !'
[echo-wss]2018/03/02 Client: Sending 'Hello WebSocket !'
[echo-wss]2018/03/02 Client: Got 'Hello WebSocket !'
[echo-wss]2018/03/02 Client: Sending 'Hello WebSocket !'
[echo-wss]2018/03/02 Client: Got 'Hello WebSocket !'
```
## QUIC
### server
