Because packets come from different sources, a border router may also be a core router. But this advantage declines with the increase of hops between source and destination.

But the storage requirement on each router grows when the packet number increases. Figure 9 shows RIHT needs only one computation to find a logged path because it has just one table. Author information Article notes Copyright and License information Disclaimer.

Hybrid single-packet IP traceback with low storage and high accuracy. National Center for Biotechnology InformationU. Network support for IP traceback. And the path reconstruction requires hop-by-hop queries of previous pverlay. Communications of the ACM. As shown in Figure 4when a router’s degrees are below 90, the table’s leve size decreases quickly with the increase of router degrees.

Botnet in DDoS Attacks: When a router receives the packet, it uses the packet’s destination IP as an index to choose a log table to log this mark.

Total number of its routers is ,; its average hop count of paths is After packet P 2 passes through the routers R 1 and R 2it enters R 3 and needs to be logged. A more practical approach for single-packet IP traceback using packet logging and marking.

However, the use of quadratic probing has caused half of his log tables pevel be tracebqck and this results in a waste of space to the routers. Recent years have seen the rapid growth of the Internet, and the widespread Internet services have become a part of our daily life. Our traceback scheme consists of two stages: The size of our log tables can be bounded by route numbers. RIHT defines its load factor according to the chance of their successful and unsuccessful searches, and it finds its unsuccessful search rate soars when each log table has used over half its slots.


Oevrlay flow-based traceback scheme on an AS-level overlay network. If the log tables are refreshed, overlya traceback scheme is unable to reconstruct the attack route. The steps of how we trace the origin of an attack will be elaborated in the following subsections. The probe numbers will slightly increase if we take into account the probes of those filled-up tables.

The other type encodes a packet’s route as a mark and stores it in the packet’s header. Thus, we can avoid the paths that have been logged twice in the tables. Figure 2 a exemplifies our marking and logging scheme. In practice, however, most routers do not verify a packet’s source IP. The author declares that there is no conflict of interests regarding the publication of this paper.

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

A marking scheme using huffman codes for IP traceback. The Scientific World Journal. To deal with this threat, we propose an overlay network that provides an IP-traceback scheme at the level of autonomous systems.

Our proposed autonomous system-level IP-traceback system contrasts with previous works because it does not require a priori levvel of the network topology netwok allows single-packet traceback and incremental deployment.

In the following discussion, we use D R i to indicate the degree of router R ithat is, the number of routers adjacent to R i.

Storage-Efficient Bit Hybrid IP Traceback with Single Packet

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 scheme sets a threshold to determine whether to log UI or to mark UI in a packet, so as to solve the storage and fragmentation issues at the same time. Therefore, we suggest that routers set the table’s maximum size as bits and the threshold These services, however, are vulnerable to many potential threats.


Single Packet IP Traceback Protocol In order to prevent packet drop caused by fragmentation and high storage requirements, we propose a new marking scheme to further decrease the storage requirements for a router. When the threshold is set as 10, the table has 8 entries bits and the router has the fewest logging times. But in a software exploit attack, a villain needs to find the host’s vulnerabilities and then uses only a few packets to launch attacks, for example, Teardrop attacks and LAND attacks [ 2 ].

In doing so, we can effectively lower the logging frequency. These schemes decrease the false negative rate because the logged data in a router does not need to be refreshed.

Since the exhaustive search consumes lots of computation power of a router, it makes their traceback scheme not practical. Showing of 18 extracted citations. Also, the values of Fragment Flag and Fragment Offset are used to show whether a packet is fragmented or not.
