Skynet 通过内部注册的协议进行消息传输。看以下简单例子：

    1、首先我们新建一个服务network；

    2、然后对其进行发送一条lua消息，让其调用start函数进行输出；

main.lua

local skynet = require "skynet"

local function main()
    local n = skynet.newservice "network"
    skynet.send(n,"lua","start")
    skynet.exit()
end


skynet.start(main)

network.lua

local skynet = require "skynet"

local CMD = { }


function CMD.start(...)
    print "hello world!"
end

skynet.start(function()

    skynet.dispatch("lua",function(session,type,cmd,...)
        local f = assert(CMD[cmd])
        if f then
            f()
        end

    end)
end)
