In addition to basic data like source and destination IP address, port, protocol, etc., We also utilize nom , an excellent Rust parser combinator library, for high-performance decoding of application layer protocols like DHCP, DNS, and HTTP. Rust’s performance and low memory use is a key benefit here.

There exist several protocols, from different network layers that can be used for OS fingerprinting. Figure 1 displays these protocols, based on the Open Systems Interconnection (OSI) model. Over this protocol, a unique physical identifier, called the MAC address, is allocated to the network interface card (NIC) of each network device.

Border Gateway Protocol (more commonly known as BGP ) is the routing protocol that makes the internet work. One way to think about it is that RPKI is to BGP what DNSSEC is to DNS. The entire RPKI process stands outside of the BGP routing protocol itself. That protocol is called RTR (meaning “RPKI-to-router” protocol).
