An AS-level overlay network for IP traceback – Semantic Scholar

In this section, we will introduce our simulation environment and how we determine log table size and the threshold.

Total number of its routers is ,; its average hop count of paths is But in the two schemes, if a packet’s size exceeds the maximum transmission unit MTUthe packet will be fragmented and cannot be assembled at the destination. Generalized Bloom Filters Rafael P. Likewise, TOPO [ 16 ] lecel each upstream router’s identifier to decrease the chance of collision and false levdl. Network support for IP traceback.

Storage-Efficient Bit Hybrid IP Traceback with Single Packet

From This Paper Figures, tables, and topics from this paper. However, in Yang’s bit hybrid single IP traceback scheme [ 26 ], he uses the quadratic probing algorithm to search an available zn for his log tables and to minimize the impact of collision.


According to the table number and the index value, the packet’s route is logged on the router.

Also, we propose a logging scheme to further reduce the storage requirements for logging. Analysis of internet backbone traffic and header anomalies observed. Hence, IPsec may not work because of the high chance of packet fragmentation and because of the difficulty in packet reassembly.

Storage-Efficient 16-Bit Hybrid IP Traceback with Single Packet

Figure 8 shows our storage requirements and RIHT’s storage requirements do not linearly increase with packet numbers because they have constant logging frequency. For these reasons, hybrid single packet traceback schemes have been proposed to combine packet marking and packet logging.

These methods can achieve single lp tracking and have lower storage requirements and false positive rates. Table 3 Comparison results.

An AS-level overlay network for IP traceback

Its false positive rates equal its fragmentation rates 0. Because our scheme, HAHIT, and RIHT have low storage requirements, routers can keep the path info az a long time and therefore do not need to refresh their log tables under flood attacks, hence 0 false negatives.

And the path reconstruction requires hop-by-hop queries of previous aa. The grey cells in Figure 2 indicate the indexed entries of the log tables. But HAHIT and our scheme have to find the log table first and then the index value, hence two probes at least. As shown in Figure 4when a router’s degrees are below 90, the table’s maximum size decreases quickly with the increase of router degrees.

Therefore, packet-marking schemes are proposed forr trace the real source of flooding-based packets. In the simulation, we send the packets to a randomly chosen path and count the logging times on the largest router in CAIDA’s dataset, whose degree is There are two types of these hybrid single packet traceback schemes: Relation among Threshold, Table Size, and Logging Times Since the logging algorithm is determined by the threshold of a router’s degree, we send 10 million packets to the network to find out the maximum storage requirement of our scheme.

Our traceback scheme will be elaborated in the following sections. Since the size of a marking field is fixed, a large index will leave a small space for the packet mark. If there are any routers unable to ae with this scheme, they can establish a tunnel to communicate with each other. To deal with this threat, we propose an overlay network that provides an IP-traceback scheme at the level of autonomous systems.

Table 2 Example of any log table HT k. To prevent the problem of insufficient table entries, we create a new table when the table is full. As for RIHT, it has lower logging frequency than our yraceback because its marking field requires 32 bits and therefore has lower chance of overflow. To simulate the Internet topology, we use the skitter project topology distributed by CAIDA [ 29 ] qs our sample data set of the Internet.
