2) Fragmentation and Reassembly of Datagrams. To understand what is IPv4 Datagram Fragmentation, first we should know the term MTU (Maximum Transmission Unit). MTU is the size (in bytes) of the largest packet or frame that can pass through a specific device or NIC card.he minimum-length of an IPv4 Datagram is 20 bytes (The minimum size of an IP header is 20 bytes and this is the case of an IPv4 header carrying no data) and the maximum is 65,535 bytes (maximum possible value for a 16 bit number is 65,535).
When using the product in a server-free environment (i.e. distributed mode), it is necessary to log into the client computer using the manager application. To do this, run the Bandwidth Controller Client application from the start menu, and connect to the IP address of the client that you wish to limit. For centralized installation (i.e. gateway mode), log into the gateway computer using the client application.
1. To track your usage on Windows we're going to use a free program called ShaPlus Bandwidth Meter. Download it from here.
