header should appear only once, except for the destination Address option header, which appears up to two times (once before the routing header, once before the upper-level protocol header). If the top protocol header is another IPV6 header (in the case of using channel technology or encapsulated in IPV6), it can have its own extension header later. These extension header are arranged separately in the sam

We have briefly introduced the HART protocol physical layer Specification Based on Software Design in the previous article. By understanding the OSI model and the knowledge about the HART protocol, we know that the specifications at the data link layer are still complex. Now let's take a look. HART protocol data link l

globally, when accessing another service provider, the service provider that is accessed first interacts directly with the identity provider to ask if the user is globally logged on, and if the user is determined to be globally logged in, allows the user to access the services he or she provides, otherwise redirects the user to the identity provider. For a global login.In a specific single sign-on implementation, the identity provider and service provider interact in different ways. If Microsof

, especially this format appears in the "to:", "From:" and "cc:" fields of the Information header. If the SMTP Server accepts the forwarding task, but later it finds that the mail cannot be sent due to incorrect forwarding path or other principles, it must establish an "undeliverable mail" signal, send this signal to the sender of the message. This signal must be sent from the SMTP service of this host. Of course, this server should not report any error messages. One way to prevent this error re
