A Study of VPN Growth Trends for Network Planning
نویسنده
چکیده
IP based Virtual Private Networks (VPNs) are being deployed as the solution of choice for site-to-site communication for a large number of enterprises. The provider networks that support these services are faced with unique challenges in terms of network planning. There is a lot of value in understanding the characteristics of VPNs from the perspective of planning, provisioning and maintenance of the service provider network. Recent studies have provided architectural and design guidelines to build efficient VPN services [2, 3, 4]. In essence, the customer’s requirements can be characterized in terms of a hose that delivers a contracted service [1]. Further, the nature of customer traffic can be better understood using specialized methods to derive approximate traffic matrices for such IP VPNs [5].

A Planning Framework for Implementing Virtual Private Networks
A virtual private network (VPN) is simply secure network connectivity over a shared public network—basically, a private network on a public network infrastructure (the Internet). Figure 1 (next page) shows an example of a network layer VPN (adapted from Paul Ferguson and Geoff Huston, “What is a VPN? Part I,”The Internet Protocol J., June 1998,pp.2-19).Corporation X’s subnetworks (which belong ...
متن کاملSIP over IP VPN: Performance Analysis
With rapid growth in use of multimedia applications, including IP Telephony (also known as Voice over IP), the demand for security and privacy of communications has significantly increased. Given the fact that IP Telephony utilizes public IP infrastructure, deployment of IP VPN is one approach to protect traffic of interest. However, VPN is presumed to have a negative impact on VOIP performance...
متن کاملValue Prediction Network
This paper proposes a novel deep reinforcement learning (RL) architecture, called Value Prediction Network (VPN), which integrates model-free and model-based RL methods into a single neural network. In contrast to typical model-based RL methods, VPN learns a dynamics model whose abstract states are trained to make option-conditional predictions of future values (discounted sum of rewards) rathe...

irtual Private Network (VPN) is one of the major trends in the integrated broadband communications environment. There is a myriad of definitions of a VPN used in the networking community to describe a broad set of problems and solutions. In [1], Ferguson et al. define a VPN as a communications environment in which access is controlled to permit peer connections only within a defined community o...

Abstract – Distributed generation (DG) technology is known as an efficient solution for applying in distribution system planning (DSP) problems. Load growth uncertainty associated with distribution network is a significant source of uncertainty which highly affects optimal management of DGs. In order to handle this problem, a novel model is proposed in this paper based on DG solution, consideri...
