Raw sockets

Raw sockets offer the option of writing and reading data at protocol header level. SOCKETS(BS2000) permits this for the Internet Control Message Protocol (ICMP) and for the Internet Control Message Protocol for IPv6 (ICMPv6). As a result, a sockets application with a raw socket is able to generate an ICMP/ICMPv6 echo request and to receive an ICMP/ICMPv6 echo reply.
