Trajectory Sampling: Extend trajectory sampling to the case where different routers wish to have the flexibility to store a different number of packet labels because of different storage capabilities. Describe a mechanism that accommodates this and how this affects the potential uses for trajectory sampling. 5. Passive Measurement and Denial of Service: In SYN flooding attacks, an attack sends TCP SYN packets to a destination D it wishes to attack using a series of fictitious source addresses. When D replies to the (often) fictitious host, these packets are not replied to. Thus D accumulates a backlog of connections that are “half-open” and eventually refuses to accept new connections. Assume you are working at a university and you have an unused Class A address space. How might you use this address space to infer denial-of-service attacks going on to various destinations on the Internet? Assume that attackers pick fake source addresses randomly from the 32-bit address space. More details for the curious reader can be found in [MVS01].
