Types of Switching Modes |Differences between the Switching Modes with Clear Explanation
In any switching mode, the parts of the frame header of a packet or a frame is analyzed.
A frame contains the following parts according to IEEE 802.3 standards,
Frame Header: The frame header is part which contains the basic information about a frame, such as,
The preamble: which is a stream of 1s and 0s. That provides synchronization of packets or frames
The Destination address: The destination MAC Address where the packet is to be delivered
The Source address: The MAC address of the system from where the packet originated
Type: The type of Ethernet protocol being used for communication
Start Frame delimiter SFD is a one byte data. It is the starting point of the packet.
Data: The data being transferred in the packet, it is generally around 46-1500 bytes long.
Frame Check Sequence: The Frame Check Sequence or FCS contains a 4 byte long Cyclic Redundancy Check(CRC) to check for corrupted data.
