There are many terms used to describe a network interface that doesn’t lose even a single packet. Common terms include “lossless packet capture”, “line-rate packet capture”, “wire-speed packet capture” and the phrase I have used: “100% packet capture”. But no matter what you call it the need and requirement is the same.
Not every application requires zero packet loss, but for those that do, such as security and network monitoring, the requirement is absolute and there can be no compromise. After all, if your security application is searching for the proverbial needle in a haystack you cannot afford to have some hay missing, as that might be exactly where the needle lies.
Each Accolade ANIC adapter port captures 100% of the incoming traffic, irrespective of packet size (i.e. 64 bytes vs. jumbo frames), without dropping a single packet. Furthermore, line-rate packet capture is supported irrespective of which packet processing functions (e.g. packet filtering) are enabled. Abundant onboard buffer memory is available to absorb abnormally large bursts of traffic.
