First Claim
Patent Images
1. A method for administering requests for data communications connections in a wide area network that includes a plurality of networks, the method comprising:
- receiving, according to a data communications protocol, by a receiver from a sender, a request for a data communications connection, wherein the sender has a network address on a sender'"'"'s network, the receiver has a network address on a receiver'"'"'s network, and the receiver has a receiver port having a state;
characterizing the sender as local with respect to the receiver'"'"'s network if the sender'"'"'s network is the receiver'"'"'s network;
characterizing the sender as remote with respect to the receiver'"'"'s network if the sender'"'"'s network is not the receiver'"'"'s network;
setting a value of a location response flag by an application program'"'"'s subroutine call through an application programming interface for the data communications protocol; and
responding to the request in dependence upon;
the value of the location response flag;
the characterization of the sender'"'"'s network with respect to the receiver'"'"'s network; and
the receiver port state, wherein the receiver port state is either a closed port state or an open port state and wherein;
a closed port state is the state of a port that either does not exist or the state of a port that has not been instructed to listen; and
an open port state is the state of a port that exists and has been instructed to listen.
