Packets dropped by custom NT4 WAN drivers. Each file moves slowly, but the total throughput can be acceptable. Existing applications may gain an advantage when the transmission path includes a satellite link equipped with Mentat technology. Global Packet loss measured in July 2000. It is hard to identify where any particular packet on the Internet is lost.
Routers discard incoming packets that can t be stored or transmitted .
Each packet has a mathematical sum of the bits it contains appended to it. When a receiving router or station receives a packet whose contents and the appended sum don t agree, that packet is discarded. Internet packet traffic moves over these same networks, and if it looks like there are too many packets to get all the voice and video through without missing a bit, packets are discarded until there is room for the voice and video. Similarly Cisco and Nortel backbone routers offer packet discard policies, so the operator of the router can decide which types of traffic will suffer lost packets as the router approaches congestion. 600 milliseconds is a typical ping time when a satellite is in the path.
