What Does Virtual Switch (VSwitch) Mean?A virtual switch (vSwitch) is a software application that allows communication between virtual machines. A vSwitch does more than just forward data packets, it intelligently directs the communication on a network by checking data packets before moving them to a destination.
Virtual switches are usually embedded into installed software, but they may also be included in a server’s hardware as part of its firmware. A virtual switch is completely virtual and can connect to a network interface card (NIC). The vSwitch merges physical switches into a single logical switch. This helps to increase bandwidth and create an active mesh between server and switches.
