Methods circuits devices systems and associated computer executable code for conveying information between network elements over an open dataflow

摘要

Disclosed are methods, circuits, devices, systems and associated computer executable code for providing information exchange between two or more network elements of a communication network over an existing or open dataflow. According to embodiments, there may be provided two or more network elements adapted to perform deep packet inspection of an existing packet and to modify one or more fields of the packet header to include information to be conveyed to another network element further along the packet flow path. According to some embodiments, one or more of the network elements may reside within a tunneled area of the communication network.
