Software stability is a major issue on any platform, but especially network appliances since it could affect the availability of a network. Anyone who uses software has most likely experienced problems that hang and/or force a reset of a computer or program. Such problems also occur in network appliances, and there may be times when there are no administrators around to get the appliance up and running again when things go wrong. The interruption of network connectivity could cause a tremendous loss in business even if it only lasts for a short period of time. Therefore, a method for out-of-band communication (i.e., communications that occur outside of a previously established communication channel) should be considered as a backup solution. Such out-of-band communications are most frequently enabled through a solution known as “LAN bypass.”
In the latest Lanner Generation Three bypass, a microcontroller has been added to give more flexibility and more advanced functionality to the bypass function. By using the non-volatile memory in this microcontroller, complex configurations can be stored regardless of the system’s operating state.
