Out-of-band Control
Out-of-band control is a characteristic of network protocols with which data control is regulated. Out-of-band control passes control data on a separate connection from main data. Protocols such as FTP use out-of-band control. FTP sends its control information, which includes user identification, password, and put/get commands, on one connection, and sends data files on a separate parallel connection. Because it uses a separate connection for the control information, FTP uses out-of-band control.

Out-of-band Management
In systems management, out-of-band management involves the use of management interfaces (or serial ports) for managing networking equipment. Out-of-band (''OOB'') management is a networking term which refers to accessing and managing network infrastructure at remote locations, and doing it through a separate management plane from the production network. Cellular 4G and 5G networks are used today for out-of-band management and many manufacturers have it as a product offering. Out-of-band management is now considered an essential network component to ensure business continuity. Out-of-band management allows the network operator to establish trust boundaries in accessing the management function to apply it to network resources. It also can be used to ensure management connectivity (including the ability to determine the status of any network component) independent of the status of other ''in-band'' network components. In computing, one form of out-of-band management is sometimes ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In-band Control
{{Unreferenced, date=June 2019, bot=noref (GreenC bot) In-band control is a characteristic of network protocols with which data control is regulated. In-band control passes control data on the same connection as main data. Protocols that use in-band control include HTTP and SMTP. This is as opposed to Out-of-band control used by protocols such as FTP. Example Here is an example of an SMTP client-server interaction: Server: 220 example.com Client: HELO example.net Server: 250 Hello example.net, pleased to meet you Client: MAIL FROM: Server: 250 jane.doe@example.net... Sender ok Client: RCPT TO: Server: 250 john.doe@example.com ... Recipient ok Client: DATA Server: 354 Enter mail, end with "." on a line by itself Client: Do you like ketchup? Client: How about pickles? Client: . Server: 250 Message accepted for delivery Client: QUIT Server: 221 example.com closing connection SMTP is in-band because the control messages, such as "HELO" and "MAIL FROM", a ...
