However, so far, no Internet-level IP trace back system has ever been deployed because of deployment difficulties. In this paper, we present a flow-based trace.

RIHT, however, requires 32 bits for marking and consequently cannot make 0 false positives. Figure 7 shows the average storage requirements on each router. Item Unique Identification Network packet Web service. Likewise, TOPO [ 16 ] uses each upstream router’s identifier to decrease the chance of collision and false positives. But HAHIT and our scheme have to find the log table first and then the index value, hence two probes at least.

When the degrees are over 90, UI i has to be logged in the table and therefore the marking field allows a higher index value. To reduce the storage requirements for logging, we propose two schemes in our bit hybrid traceback protocol to encode the upstream routers’ interface numbers as an index of the log table’s entry.

As depicted in the figure, compared with HAHIT our scheme requires fewer logging times and our logging times do not increase with the number of packets. Thus, we can avoid the paths that have been lp twice in the tables. But our scheme requires an interface number to be logged if it exceeds the threshold value.


But if the filter logs too many packets, there might be collision in their log tables and therefore they will have false positives during path reconstruction. A router will compare its degrees with a threshold to choose a coding scheme to calculate the mark.

Communications of the ACM. Botnet in DDoS Attacks: Compared with current hybrid single packet traceback schemes, it has the lowest tracebwck storage requirement, which means the compulsory storage requirement for a router to support our hybrid single packet traceback. Conflict of Interests The author declares that there is no conflict of interests regarding the publication of this paper. If the mark is larger than the size of a marking field, the packet’s route is logged onto a router [ 24 — 26 ] to decrease each router’s storage loads.

Besides, the scheme does not have indexes for their log tables. Then the table’s maximum size decreases with the increase of degrees.

Yang propose RIHT [ 24 ] to encode all the upstream routers’ interface numbers as their log table’s indexes. When a packet enters a network from its host, every router that complies with our protocol has to mark its own route info on the passing packets and store the mark in tracebback packet’s marking field. In order to balance the collision times and each table’s usage rate, Yang sets his load factor as 0.


In our marking scheme, we mark a router’ interface numbers and store the mark in a packet’s IP header. Open tracebwck a separate window.

Storage-Efficient Bit Hybrid IP Traceback with Single Packet

The data set consists of paths to a specific host of the topology. Our scheme lp a threshold to determine whether to log UI or to mark UI in a packet, so as to solve the storage and fragmentation issues leveo the same time. Also, we propose a logging scheme to further reduce the storage requirements for logging. If the degrees are 91, the router allows log tables whose maximum size is A router can be connected to a local network or other routers.

However, it becomes a core router when receiving packets from R 8. Castelucio and Artur Ziviani and Ronaldo M. However, both PPM and DPM require at least eight packets for path reconstruction [ 12 ], so they may not be able to trace the source of software exploit attacks, which can use only one packet to paralyze the system.

Accommodating fragmentation in deterministic packet marking for IP traceback. Figure 1 illustrates an example setup of our traceback scheme. Tracing multiple attackers with deterministic packet marking DPM. The size of our log tables can be bounded by route numbers.
