A physical Wake-on-LAN connector (white object in foreground) featured on the IBM PCI Token-Ring Adapter 2. Wake-on-LAN (WoL or WOL) is an Ethernet or Token Ring computer networking standard that allows a computer to be turned on or awakened from sleep mode by a network message.
At the server level, failover automation usually uses a "heartbeat" system that connects two servers, either through using a separate cable (for example, RS-232 serial ports/cable) or a network connection. In the most common design, as long as a regular "pulse" or "heartbeat" continues between the main server and the second server, the second ...
In such cases, more than one (M) standby servers are included and available. The number of standby servers is a tradeoff between cost and reliability requirements. N-to-1 — Allows the failover standby node to become the active one temporarily, until the original node can be restored or brought back online, at which point the services or ...
In Ethernet LANs, dual-homing is a network topology whereby a networked device is built with more than one network interface. Each interface or port is connected to the network, but only one connection is active at a time. The other connection is activated only if the primary connection fails.
Link aggregation increases total throughput beyond what a single connection could sustain, and provides redundancy where all but one of the physical links may fail without losing connectivity. A link aggregation group ( LAG ) is the combined collection of physical ports.
In cases where secondary/standby routers all have the same priority, the secondary/standby router with the highest IP address becomes the primary/active router. All physical routers acting as a virtual router must be in the same local area network (LAN) segment. Communication within the virtual router takes place periodically.
Check the physical connection - A loose cable or cord can often be the cause of a connection problem. Make sure everything is securely connected to the wall and device. 3. Reboot your modem/router - Sometimes the old "turn it off and on again" approach actually does work! Just wait about five minutes before turning it back on to make sure ...
