An improved method and system for generating packets for transmission over different routes on a network is presented. In a large network such as the Internet, each route over the network carries different size packets which are not compatible unless they are fragmented into smaller segments. Initially, the technique determines a maximum transmission unit (MTU) capable of being transmitted over a predetermined route. Next, the size of each packet to be transmitted over the network is compared with the MTU size. If the comparison indicates the packet is larger than the MTU, the packet must be processed further before it can be transmitted over the route. The additional processing initially divides the total number of transmission units contained within the packet by the MTU value. The integer result of this division is temporarily stored in a DCOUNT variable and the remainder of the division in a RCOUNT variable. If the remainder in RCOUNT is non-zero, the value in DCOUNT is incremented by one. The DCOUNT value indicates the minimum number of datagrams for sending a packet using the present technique. Next, the transmission units contained in the original packet are redistributed equally into DCOUNT packets and then sent over the network route.
