ROUTER BUFFER EFFECTS ON THE PERFORMANCE OF TCP AND UDP
Author: Samaira Mahajan S.G

ABSTRACT :
In data communication, congestion occurs when there are so many packets contending for
the limited shared resources, such as the queue buffer in the router at bottleneck link.
During congestion, large amount of packets experience delay or even be dropped due to
the queue overflow. Severe congestion problems result in degradation of the
throughput and large packet loss rate. In this paper, considering two popular queue
management methods, Random Early Detection (RED) and LALRED the analysis of throughput
and packet loss rate for different buffer sizes is presented. The results show that with increase
in buffer size for RED, the throughput and efficiency of TCP increases. A l s o , UDP packet
loss decreases with an increase in buffer size while the buffer size has no key impact on UDP
packet delays. Simulation results obtained using NS2 establish the improved performance of
LALRED over the RED and the graphs are plotted using GNU plot.

BUG TRIAGE AND DATA REDUCTION TECHNIQUES: A COMPREHENSIVE SURVEY
Author: Tripti Ambadkar

ABSTRACT :
Software industries spend more than 45 percent of expense in managing programming bugs.
An unavoidable stride of altering bugs is bug triage, which expects to effectively allocate a
designer to another bug. To diminish the time cost in manual work, content characterization
procedures are connected to direct programmed bug triage. In this, we address the problem of
information decrease for bug triage, i.e., how to diminish the scale and enhance the nature of
bug data. We join example choice with highlight determination to at the same time lessen
information scale on the bug measurement and the word measurement. To focus the request
of applying example choice and highlight determination, we separate properties from
verifiable bug information sets and construct a prescient model for bug information set.

A STUDY ON THE DIFFERENCES BETWEEN AGILE AND TRADITIONAL WATERFALL SOFTWARE DEVELOPMENT METHODS"
Author: Rashmi Pawar

Abstract: This paper will focus on traditional SDLC method like Waterfall model and will brief
on comparative study of same with Agile.
Traditional SDLC models like Waterfall model is sequential development methodology where
output of one development phase becomes input for other. To brief cons, like risk of failure are
high and process itself is not flexible for change.
Agile software development methodology is widely used software development process which
overcomes the drawbacks of traditional software development methods.It provides means for
rapid development and great deal of flexibility to adopt new changes during development
process.
The primary data collection method was interviews of the industryexpertise. The secondary
source of data is reference books and Internet articles. This paper will help to understand basics
of Agile methodology.
Keywords-Agile methods,Agile methodology, Software development, Software Development
Life Cycle(SDLC)
