Des-sert is a framework written as ansi-c library. while generally usable in many application scenarios, it is primarily used in des-mesh, the multi-transceiver wireless mesh network testbed part of the des-testbed. des-sert enables the implementation of routing protocols via an underlay in user space.

des-sert routing daemons utilize libpcap to receive packets from the network resp. to send them. locally generated packets or packets destined to this host use a tun or tap interface as access point to the operating system protocol stack.
