Abstract: One embodiment relates to an automated method of detecting transmission control protocol (TCP) anomalies. A TCP connection is selected to be monitored. Packets communicated for the TCP connection are scanned in chronological order of packet communication times. A signature is created for the connection based on the scanned packets, and said signature is characterized to detect anomalous behavior of the TCP connection being monitored. Other embodiments, aspects and features are also disclosed.

Abstract: A fishing line release system is disclosed. The fishing line release system includes a fishing line quick release mechanism that may be used in conjunction with a planar device for trolling or may alternatively be used with a down rigger cable and weight when used in down rigger fishing. When used in conjunction with the planar device, the system may be used for directional trolling. The planar device comprises a planar body, the fishing line quick release mechanism attached to the planar body, and a line locking assembly for securing a portion of a fishing line to the planar body. When used in conjunction with a down rigger cable and weight, the quick release mechanism may be used either on the down rigger cable or may be attached to the down rigger weight.
