What are out-of-band channels?

What are out-of-band channels?

Out-of-band (OOB) refers to a separate communication channel severed from the primary in-band channel over which the actual network communication occurs [11, 19]. OOB channel provides robustness against attacks by introducing a second, independent communication channel.

What is an out-of-band communication?

Out-of-band agreement, an agreement or understanding between the communicating parties that is not included in any message sent over the channel but which is relevant for the interpretation of such messages. More broadly, communication by any channel other than the primary channel can be considered “out-of-band”.

What is an out-of-band process?

In computer networking, out-of-band data is the data transferred through a stream that is independent from the main in-band data stream. An out-of-band data mechanism provides a conceptually independent channel, which allows any data sent via that mechanism to be kept separate from in-band data.

What is in-band and out-of-band communication?

In telecommunications, in-band signaling is the sending of control information within the same band or channel used for data such as voice or video. This is in contrast to out-of-band signaling which is sent over a different channel, or even over a separate network.

What is out-of-band data in TCP?

TCP does not have true out-of-band data. Instead, TCP provides an urgent mode. Assume a process has written N bytes of data to a TCP socket and that data is queued by TCP in the socket send buffer, waiting to be sent to the peer.

What is in band and out-of-band management?

In–band management is used to manage devices through telnet/SSH, using the network itself as a media. Out-of-band management uses terminal server that is connected to a management port of each controlled device.

What is the difference between in band and out of band management?

While In-Band Management is the ability to administer a network via the LAN, Out-of-Band Management is a solution that provides a secure dedicated alternate access method into an IT network infrastructure to administer connected devices and IT assets without using the corporate LAN.

What is out-of-band data in socket?

Out-of-band data is a logically independent transmission channel between a pair of connected stream sockets. Out-of-band data is delivered independent of normal data. The out-of-band data facilities must support the reliable delivery of at least one out-of-band message at a time.

What is inband and out-of-band management?

What is a characteristic of out-of-band device management?

What is a characteristic of out-of-band device management? It requires a terminal emulation client. Out-of-band device management requires a direct connection to a network interface. It requires Telnet, SSH, or HTTP to access a Cisco device.

What are out-of-band devices?

Out-of-Band provides presence and proximity to these devices, with an appliance at every compute location, physically connected to critical network devices at the site. The independent management plane provides the core team with secure access to equipment remotely.
