Section 3.3 of our original paper linked below describes the forwarding algorithm as well as the header format. https://www.usenix.org/system/files/conference/nsdi12/nsdi12-final13.pdf One can find the reference to this paper in our XIA 101 page in our wiki: https://github.com/AltraMayor/XIA-for-Linux/wiki/XIA-101 The code does transmit packet, you can find function __xip_fill_in_hdr() in file net/xia/output.c (https://github.com/AltraMayor/XIA-for-Linux/blob/xia/net/xia/output.c) that fills out the XIP header, and examples to how set up some experiments with our stack are available here: https://github.com/AltraMayor/XIA-for-Linux/wiki/zFilter-principal https://github.com/AltraMayor/XIA-for-Linux/wiki/4ID-principals https://github.com/AltraMayor/XIA-for-Linux/wiki/An-exemplifying-demo [ ]'s Michel Machado
