Abstract
Packet classification is an important function for a range of network management and control applications, e.g. firewalls, policy based networking, traffic accounting, and network address translation. All the packets have to be classified in proper order for emerging broadband internet services, applications such as Internet TV/Radio, gaming, Video on Demand (VoD) and e-businesses, who are in constant demand for a higher degree of transmission bandwidth, complex security, and specific Quality of Service (QoS). Packet treatment needs multiple classifications which help to justify, which flow an incoming packet belongs to, and with which rules the packet’s header fields are to be treated. So these systems ought to be compared with every packet header, in comparison, against a large set of rules, and while analysing such related packets, often incur delay. Therefore, this problem can be reduced with the help of fast packet classification algorithm. This paper presents a modified version of the packet classification algorithm, called DimCut Packet Classification Algorithm using Recursive Dimensional Cutting. In order to get extended DimCut algorithm, in addition, some discovery & result can also be obtained. Modifications could also extend the DimCut algorithm by adding some new heuristics ideas, new implementing techniques and parallel programming that classifies packets based on five header fields which we propose in this paper.

Highlights
In the recent era, electronic commerce, business and Internet are in great demand
Large scale packet classification is an important factor in Firewalls, routers, network security and Quality of Service (QoS) assurance
The packet classification requires the packets to be clearly specified with the multiple packet headers, to notify which is incoming flow and what rule the packet is to be related with
Summary
Electronic commerce, business and Internet are in great demand. It has opened a new dimension in the Internet world. Internet traffic is growing at a fast pace nowadays, because of more users and because of increased Internet multimedia applications. The faster network devices, routers and firewalls require higher bandwidth and faster Internet communication. The Giga bit optical fibers are being greatly used, they can rarely reach the optical transmission speed. Faster routers and firewalls could be useful in achieving higher Internet performance.
