Abstract
The present invention propose a new mechanism, IP check layer which enables to use TOE cards and legacy NICs simultaneously within same protocol family in a Linux or a UNIX computing environment. The IP check layer is inserted between a BSD socket layer and an INET socket layer. IP check layer maintains a routing information and, information of IP addresses of each network interfaces and each socket's bind state. Using this information, IP check layer determines how to process a socket call and which layer (TOE layer, host INET layer) will take over the socket call. By means of the above mechanism, the present invention makes existing socket applications to use TOE cards and legacy NICs at the same time without modification or recompiling.
