Software Based Scalable Packet
Capture Mechanism To Reduce
Packet Loss.
PhD thesis, Universiti Sains Malaysia.
Abstract
The advancement of packet capture technology has given a major impact in packet
capture process whereby both software and hardware solutions have been designed to
optimize packet capture performance. Packet capture has become more challenging by
which the complexity of capturing packet occurred in high packet rates and high
bandwidth which creates the need for more sophisticated packet capture mechanism in
network traffic. This thesis focuses on minimizing the packet loss in high speed network
in which it is one of the most challenging problem in packet capturing engine. By reducing
the packet loss, it gives a significant impact in several aspects in network traffic
performance particularly with related applications. In addition, reducing packet loss also
one of the key performance indicators for analyzing the quality of network. Existing
approaches in packet capture mechanism is not sufficiently capable to capture packet in
high speed network due to some bottlenecks. Packet losses in high speed network takes
place due to buffer overflow as their rate of arrival to the buffer increases. The intention
of this thesis is to propose and implement a new mechanism in capturing packet to
overcome the problem arises in the existing solutions. The proposed mechanism aims to
alleviate buffer overflow because packet drop leads to inefficiency of packet capture
performances.
