How can a network switch be said to operate at Layer 4 of the OSI model?
What will be an ideal response?
ANSWER: A Layer 4 switch is capable of interpreting Layer 4 data. They operate anywhere between Layer 4 and Layer 7 and are also known as content switches or application switches. Among other things, the ability to interpret higher layer data enables switches to perform advanced filtering, keep statistics, and provide security functions. In general, however, a Layer 4 switch is still optimized for fast Layer 2 data handling.
