A Real Time Leaky Bucket Based Admission Control Scheme For Voip Networks

We need to have a secure services and network and also it must be available sometime up to 24/7/365. To make sure that we are close to our Service level agreement (SLA) with our clients, we must check our performance to find the bottleneck. After identifying our bottlenecks we can plan and see what changes can improve our performance.

Monitored the network congestion in order to achieve the optimal performance out of a network infrastructure.

In this paper, we present the first data collection and profiling process result in our research framework. At this time, the second and the third data collection process are still on going. If it is completed, we will conduct the second part of our proposed experiment. The challenges is, we have to obtain an appropriate and enough RAW data that need more prolonged time for trial and error. We have to design scalable devices and computation architecture, since the system proposed will handle high volume of traffic at national level network. A comment and suggestion are welcome.

During this paper several things will be explained or gone over. The first will be communication protocols and I will identify the network protocols and provide rationale for the decision. Next will be to define the full network architecture and explain the usefulness of the traffic analysis. The next thing will be to define the terms response time, latency, and jitter, and describe their effect on the main network performance and on the performance of the chosen organization 's network. Next the effect of data rates on each part of the network will also be explained. Describing strategies to ensure the availability of network access in switched and routed networks will be the last part of this paper.

contains the case narrative, related figures, and a set of questions and problems. These do not have one unique solution. There are too many alternatives when dealing with LANs, WANs, MANs, BNs, and the Internet, so a reallife network design and development problem can have several workable answers.

While Internet Service Providers (ISPs) want to create a tiered approach, saving the faster speeds for their premium customers while charging “heavy band-with users” in order to generate revenue, enhance their systems and build more robust, more advanced networks,

Disadvantage: The main disadvantage of this scheme is that, since no priority is given to handoff request calls over originating calls, the forced termination probability is relatively higher than it is normally anticipated [16], and also there is no proper channel utilization.

As compared to Layer 3, where addresses in the packet header are carried from source host to destination host regardless of the number of network hops along the route, Layer 2 uses addressing to transport the frame across the local media.

As this demand for dynamic and unpredictable data grows, more and more devices have to be added to existing networks and configured accordingly. The need of the hour is to regulate networks centrally and as a whole rather than configure individual network devices and gain more control to achieve flexibility in existing networks.

Cisco provides a number of its solutions over cloud rather than preferring the infrastructure implementation since it can reduce the cost of

The latest Cisco IOS innovation of NetFlow of version 9 is flexible and extensible method to record network performance data. A comprehensive solution for NetFlow-based, planning, monitoring and billing can provides to customers.

The world today is largely dependent on the worldwide communication that the internet provides. Almost all sectors such as educational, entertainment, political and economic sectors rely on the internet network to exchange and store information. Even seconds of downtime can affect these sectors tremendously. This means that it is crucial for us to understand how these disruptions occur so that we can analyze it and improve its infrastructure. The Internet infrastructure has a lot of loopholes. It could be from any layer of the OSI model. In this project, my aim is to find out the insecurities that can disrupt the network due to a Border Gateway Protocol (BGP)

Abstract: Headway of usage of remote advances in tablets and compact terminals, which are outfitted with a couple framework interfaces, has offered customers to misuse from multi-homing to get the opportunity to network benefits wherever, at a point and from any framework. Advantage with multi homed host is that a segment of the action from more congested ways can be moved to less congested way. In this paper we consider about Multipath TCP (MPTCP), which encounters the degradation of good put inside seeing changing framework conditions on the open sub streams due to out-of-demand got groups. Purpose behind degradation is the considerable assortment of end-to-end defer for various courses over remote channels. To diminish the assortment of

In the Semi-Automated DDoS attacks the DDoS “network” is made of a handler and an agent machine. There is automation present for the Recruit, Exploit and Infect phases. Through the communication between the handler and the agent, the attacker specifies the attack type, the onset, the duration and the victims ID. The
