Abstract: Quality of Service (QoS) refers to ability of a network to provide improved service to selected network traffic over various underlying technologies including Frame Relay, ATM, Ethernet and 802.1 networks, SONETS and IP-routed networks.The traffic through this network may include data types such as email, file sharing or web traffic. Other forms of traffic include voice and video. These are considered as sensitive forms of traffic. They often require guaranteed or regulated service. In this paper, we deal in detail with two factors affecting QoS: Congestion and Queuing. Identifying and rectifying the above problems to reduce packet loss, latency and jitter on the network is the errand for the day. Few of the Queuing Algorithms like First in First out (FIFO), Priority Queuing (PQ), Round Robin and Weighted Round Robin (WRR) are explained in brief pictorially. The internet is often vulnerable to attacks from possible hackers who try to compromise the system in order to illegally poach the resources of the system under question. These attacks are famously called web attacks and are a very common problem amongst the computer fraternity. Though there are several existing systems to counter the problem of attacks on the web, most of these systems have their own drawbacks, as in they do not provide classification on any other grounds except frequency, thus causing many web attacking http requests to fall out of the bracket. The objective of our project is to detect these web attacks from the http requests based on many parameters, and classify them as web attacks or not.

Keywords: Frame Relay, ATM, Ethernet and 802.1 networks, SONETS and IP-routed networks, Congestion and Queuing, First in First out (FIFO), Priority Queuing (PQ), web attacks, web attacking http requests.
