Virtual Wiki. ToR switch placement â not at the top! You may know about ToR, top-of-rack (for) switches. Itâs the practice of placing a physical switch within each rack, so that the network switching for the rack is close to the servers or devices that need to connect to it. The ToR switches will allow servers to communicate with each other directly, and therefore reduces overall traffic on core switching.
In the Open Systems Interconnection (OSI) communications model, a switch performs the Layer 2 or Data-link layer function. That is, it simply looks at each packet or data unit and determines from a physical address (the MAC address) which device a data unit is intended for and switches it out toward that device.n a wide area packet-switched network such as the Internet, a switch determines from the IP address in each packet which output port to use for the next part of its trip to the intended destination.
