Claim 26:
27. Computer readable apparatus comprising a non-transitory storage medium, the non-transitory storage medium comprising at least one computer program having a plurality of instructions, the plurality of instructions configured to, when executed on a processing apparatus, cause an apparatus to detect a tethering function being performed by endpoint devices in a communication network, by at least:
a selection for monitoring one or more endpoint devices within the communication network, the selected devices being capable of tethering and associated with a Transmission Control Protocol (TCP)/IP traffic flow of interest;
a monitoring of the TCP/IP traffic flows associated with the selected one or more endpoint devices;
a determination, for each endpoint device, of an average baseline value RB of a rate of occurrence of a TCP/IP error condition for TCP/IP traffic flows terminating at the endpoint device;
a determination, for each endpoint device TCP/IP traffic flow of interest, of a rate of occurrence RA of the TCP/IP error condition; and
a determination, for any endpoint device TCP/IP traffic flow of interest having a respective rate of occurrence RA outside of a statistical margin of error of a respective average baseline value RB rate of occurrence, that the endpoint device TCP/IP traffic flow of interest is associated with a wireless device tethered to the endpoint device.
