WebMSS stands for maximum segment size. MSS is used by TCP at layer 4 of the Internet, the transport layer, instead of layer 3. MSS is only concerned with the size of the payload within each packet. It is calculated by subtracting the length of TCP and IP headers from MTU. While packets that exceed a router's MTU are either fragmented or dropped ... WebEthernet is a shared medium, so there are rules for sending packets of data to avoid conflicts and to protect data integrity. Nodes determine when the network is available for sending packets. It is possible that two or more nodes at different locations will attempt to send data at the same time. When this happens, a packet collision occurs.

What are Network Packets and How Do They Work?

WebThe network layer provides the means of transferring variable-length network packets from a source to a destination host via one or more networks. Within the service layering semantics of the OSI network architecture, the network layer responds to service requests from the transport layer and issues service requests to the data link layer .
