Remote network node management system and method
View Patent ↗A system for transparent switching of management sessions utilizing in-band and out-of-band technologies is provided. The system provides continuous access to the managed system(s) by combining in-band tools, which generally require lower network bandwidth and provide better response time with less latency when the system under management is in-service, with out-of-band tools that provide continued access to the system under management when the network interface or operating system become unstable or the system in placed by an operator or falls unexpectedly to an out-of-service condition.
1. A remote management system connected to a plurality of network nodes to be managed using the management system, the system comprising:
a management station that executes software to remotely monitor and control a remote network node on a common viewer based on connection option settings made at the management station including a setting for network response time;
a smart switch module appliance, located between the management station and the remote network node, that provides the common viewer at the management station access to the remote network node using a remote access protocol (1) automatically selected by the smart switch module from one of an in-band protocol and an out-of-band protocol based on a set of predetermined criteria including the connection option settings, and continuing to communicate the management information to the common viewer whether the smart switch module selects the in-band protocol or the out-of-band protocol; (2) continuously testing whether the selected remote access protocol optimally meets the connection option settings and, in the smart switch module, automatically changing to the other of the in-band protocol and out-of-band protocol anytime said other of the in-band protocol and out-of band protocol is currently determined to more optimally meet the connection option settings, and thereafter continuing to seamlessly communicate the management information to the same common viewer whether the smart switch module changed to the in-band protocol or the out-of-band protocol; (3) continuously repeating (2) each time another of the in-band protocol and out-of-band protocol is currently determined to more optimally meet the connection option settings; and
the management station remotely monitors and controls the remote network node through the smart switch module seamlessly through the single viewer using the remote access protocol without setting the remote access protocol at the management station.

7. The system of claim 6 , where the management gateway appliance is a Keyboard-Video-Mouse switch using one or more of the following list of remote access protocols: Remote Desktop Protocol (RDP), Virtual Network Computing (VNC), Independent Computing Architecture (ICA), X-windows (X.11), and Intelligent Platform Management Interface (IPMI).
8. The system of claim 6 , where the management gateway appliance comprises a serial console server using one or more of the following remote access protocols: Telnet, Secure Shell (SSH), and Intelligent Platform Management Interface (IPMI).
9. The system of claim 6 , where the management gateway appliance comprises a service processor gateway using one or more of the following remote access protocols: Telnet, Secure Shell (SSH), Remote Desktop Protocol (RDP), Virtual Network Computing (VNC), Independent Computing Architecture (ICA), X-windows (X.11).
10. The system of claim 1 , wherein the set of predetermined criteria further comprises a set of preference data associated with a user.
11. The system of claim 10 , wherein the set of predetermined criteria further comprises an availability of an in-band protocol and an availability of a out-of-band protocol.
12. The system of claim 1 , wherein the smart switch module further comprises a monitor module that monitors a connection status of the in-band protocol and the out-of-band protocol to determine the availability of each protocol, a decision engine that selects one of the in-band protocol or the out-of-band protocol based on the set of predetermined criteria, a set of protocol adapters that permit the smart switch module to interface with a plurality of remote access protocols, and a set of viewer applications capable of providing a user interface for the monitoring and controlling of the remote network node.
13. The system of claim 1 , wherein the smart switch module further comprises computer instructions executed at the management station.
14. A method of remotely managing a plurality of network nodes using a management station that executes software to remotely monitor and control a remote network node and a smart switch module appliance, located between the management station and the remote network node, the method comprising:
opening a common viewer at the management station;
setting connection option settings at the management station including a setting for network response time;
automatically selecting, at the smart module, a remote access protocol from an in-band protocol to access a remote network node and an out-of-band protocol to access the remote network node based on a set of predetermined criteria including the connection option settings;
accessing, using the smart switch module, remote network node using the selected remote access protocol;
at the management station through the common viewer, remotely monitoring and controlling the remote network node through the smart switch module using the selected remote access protocol;
at the smart switch module, continuously testing whether the selected remote access protocol optimally meets the connection option settings;
at the smart switch module, automatically changing the remote access protocol to another remote access protocol other than the selected remote access protocol anytime said another remote access protocol is currently determined to more optimally meet the connection option settings; and
continuing to seamlessly communicate the management information to the same common viewer when the smart switch module changes to said another remote access protocol.
15. The method of claim 14 , wherein the set of predetermined criteria further comprises a set of preference data associated with a user.
16. The method of claim 15 , wherein the set of predetermined criteria further comprises an availability of an in-band protocol and an availability of a out-of-band protocol.
