The Internet architecture works well for a wide variety of communication scenarios. However, its flexibility is limited because\nit was initially designed to provide communication links between a few static nodes in a homogeneous network and did not\nattempt to solve the challenges of today�s dynamic network environments. Although the Internet has evolved to a global system of\ninterconnected computer networks, which links together billions of heterogeneous compute nodes, its static architecture remained\nmore or less the same. Nowadays the diversity in networked devices, communication requirements, and network conditions vary\nheavily, which makes it difficult for a static set of protocols to provide the required functionality. Therefore, we propose a self aware\nnetwork architecture in which protocol stacks can be built dynamically. Those protocol stacks can be optimized continuously\nduring communication according to the current requirements. For this network architecture we propose an FPGA-based execution\nenvironment called Embed Net that allows for a dynamic mapping of network protocols to either hardware or software. We show\nthat our architecture can reduce the communication overhead significantly by adapting the protocol stack and that the dynamic\nhardware/software mapping of protocols considerably reduces the CPU load introduced by packet processing.
