A large table leads to large index values and large marks, which will cause high logging frequency in the downstream routers. Ndtwork other type encodes a packet’s route as a mark and stores it in the packet’s header.

It is because our log tables allow more entries on the routers whose degrees are under the threshold value 10, and because we do not use fixed-size tables. By clicking accept or continuing to use the site, you agree to the terms outlined in our Privacy PolicyTerms of Serviceand Dataset License.

However, in Lu et al. Introduction Recent years have seen the rapid growth of the Internet, and the widespread Internet services have become a part of our daily life. If packet numbers exceed a router’s storage limit, its log tables have to be refreshed. Botnet in DDoS Attacks: But a logging table with limited size will be filled up quickly if we use a hashed source IP to determine the table number. In order to balance the collision times and each table’s usage rate, Yang sets his load factor as 0.

A border router receives packets from its local network and sends the packets to the destination through a core router.


When a router receives a packet P j and needs to log its mark, the router checks its degree D R i to decide whether or not to log the interface number UI i ; compare lines 29—33 in Algorithm 1. From This Paper Figures, tables, and topics from this paper.

An AS-level overlay network for IP traceback

LauferPedro B. Figure 9 shows RIHT needs only one computation to find a logged path because it has just one table.

Relation between Ovrelay Degree and Table Size As dor in Figure 4when a router’s degrees are below 90, the table’s maximum size decreases quickly with the increase of router degrees.

Yang propose RIHT [ 24 ] to encode all the upstream routers’ interface numbers as their log table’s indexes.

Storage-Efficient Bit Hybrid IP Traceback with Single Packet

xn As depicted in the figure, compared with Tracenack our scheme requires fewer logging times and our logging times do not increase with the number of packets. There are two types of these hybrid single packet traceback schemes: And this can cause higher logging frequency. A probabilistic marking scheme for fast traceback. A novel approach for single-packet IP traceback based on routing path. The grey cells in Figure 2 indicate the indexed entries of the log tables.

A flow-based traceback scheme on an AS-level overlay network. The storage requirements of logging are bounded by the number of upstream routes, and no duplicate route is logged. As shown in Algorithm 2when a victim detects P j as an attack packet at the time T rit sends P j and T r to the tracking server and requests the server to find the attack source.

TTL based packet marking for IP traceback. In this paper we propose a bit single packet IP traceback scheme. As these packets are usually in a huge amount, these marking schemes are categorized as probabilistic packet marking PPM [ 3 — 9 ] and deterministic packet marking DPM [ 10 — 14 ].


Table 2 Example of any log table HT k. Because our scheme, HAHIT, and RIHT have low storage requirements, routers can keep the path info for a long time and therefore do not need to refresh their log tables under flood attacks, hence 0 false negatives.

Since the exhaustive search consumes lots of computation power of a router, it makes their traceback scheme not practical. Our traceback scheme consists of two stages: 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. International Journal of Internet Protocol Technology.

A more efficient hybrid approach for single-packet IP traceback. As shown in Table 1we use the bit ID field as our marking field in our traceback scheme.

Therefore, we suggest that routers set the table’s maximum size as bits and the threshold Therefore, when adversaries send attack packets with a forged path in the marking field trying to confuse our tracking, we can still locate their origin correctly.

Conflict of Interests The author declares that there is no conflict of interests regarding the publication of this paper. This is why attackers usually take this advantage and spoof their real address to evade tracking.
