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 You will be shown the web interface for your TP-Link router. 2  Open the section IP & Mac Binding â ARP List and note down the IP address of the person or device for which you want to limit the bandwidth.3  In my case, this IP address is 198.168.0.100. 4  Open the section Bandwidth Control â Control Settings.inally I figured out how to limit the internet bandwidth in a TP-Link router and shared only 2 mbps with my neighbors, leaving me with a comfortable share of the internet bandwidth. If you also want to limit the bandwidth in your TP-Link WiFi router (or modem+router combo), then you can follow these simple steps:
