Any TCP system call that is made is received by the socket layer.
套接字层接收进行的任何TCP系统调用。
The socket layer validates the correctness of the parameters passed by the TCP application.
套接字层验证tCP应用程序传递的参数的正确性。
Note that this feature might not be able to use a browser's encryption facilities such as Secure Socket Layer (SSL).
注意，这个特性不能使用浏览器的加密设施，比如SecureSocket Layer (SSL)。
Below the socket layer is the protocol layer, which contains the actual implementation of the protocol (in this case, TCP).
套接字层下面是协议层，该层包含协议的实际实现(本例中为TCP)。
Combining security of SSL protocol and find-grained access control, SSL VPN(Secure Socket Layer Virtual Private Netwrok) does well in resolving this problem.
结合SSL的加密特性和细粒度的访问控制，很好地解决了上述问题。
In the case of receiving out-of-band data, the protocol layer checks for different conditions to validate that the received data is OOB, and then returns it to the socket layer.
在接收带区外数据的情况下，协议层检查不同的条件，以验证接收的数据是否为带区外数据，然后将其返回到套接字层。
The UDP layer of the stack keeps track of the quantities of the writes and ensures that when the receiver on the right gets the data through the socket, it arrives in the same quantities.
协议栈的UDP层追踪写的数量，并确保当右边的接收者通过套接字获取数据时，它以同样数量的字节到达。
The control now returns to the connect function, which sleeps until the protocol layer wakes up-indicating that the connection is now ESTABLISHED or that there has been an error on the socket.
控制现在返回到connect函数，该函数处于睡眠状态，直到协议层唤醒—指示连接现在是ESTABLISHED，或套接字上存在错误。
Upon returning from soconnect , the connect function issues a sleep until the protocol layer wakes it up, indicating that the connection is ESTABLISHED or there has been some error on the socket.
从soconnect返回时，connect函数进入睡眠状体，直到协议层将其唤醒，并指示连接是ESTABLISHED或套接字上存在错误。
And this chip contains PHY layer, so it can connect to RJ45 socket which has built-in transformer directly.
另外该芯片内置以太网物理层可直接连接内置变压器的RJ 45插座，而不需要专用的物理层芯片。
