This document provides network architects with a general understanding of how to leverage network
virtualization to make a centralized NAC Appliance deployment easier. This document allows the
network architect to select a design and reference the specific implementation details in the associated
design guides. The foundation technologies associated with enterprise network virtualization
architecture are divided into the following three functional areas:
• Access control
• Path isolation
• Services edge...
This document provides design guidance for enterprises that want to provide Internet and limited
corporate access for their guests and partners. Several solutions for guest and partner access challenges
are proposed and analyzed in this document, at both the architectural and functional levels.

Virtual Private Networks (VPN) hay gọi theo tiếng Việt là Mạng Riêng Ảo, cho phép bạn mở rộng phạm vi mạng nội bộ bằng cách sử dụng lợi thế của internet. Kỉ thuật VPN cho phép bạn kết nối với một host nằm xa hàng ngàn dặm với mạng LAN của bạn và làm cho nó trở thành một node hay một PC nữa trong mạng LAN. Một đặc điểm nữa của VPN là sự kết nối giữa clients và mạng ảo của bạn khá an toàn như chính bạn đang ngồi trong cùng một mạng LAN....
Đồ án tốt nghiệp: Mạng riêng ảo (VPN - Virtual Private Network)- ĐH Công Nghiệp HN sẽ là tài liệu tham khảo hữu ích giúp các bạn sinh viên làm tốt đồ án tốt nghiệp. Mạng riêng ảo VPN (Virtual Private Network) là một mạng riêng rẽ sử dụng một mạng chung (thường là Internet) để kết nối cùng với các site (các mạng riêng lẻ) hay nhiều người sử dụng từ xa.
Trong bài này chúng tôi sẽ giới thiệu cho các bạn về VMware ‘Virtual Switch’. Virtual Switch chỉ là một kết cấu chuyển mạch logic gắn với cơ sở hạ tầng Vmware (ESX) để có thể kết nối các máy ảo theo nhiều cách
The world of IT is always evolving, but in every area there are stable, core concepts that anyone just setting out needed to know last year, needs to know this year, and will still need to know next year. The purpose of the Foundations series is to identify these concepts and present them in a way that gives you the strongest possible starting point, no matter what your endeavor.
Network Security Foundations provides essential knowledge about the principles and techniques used to protect computers and networks from hackers, viruses, and other threats.
The merging of voice and data on a single network opens powerful new possibilities in communications. Only a fundamental understanding of both technologies will ensure you are equipped to maximise their full potential.
Convergence Technologies for 3G Networks describes the evolution from cellular to a converged network that integrates traditional telecommunications and the technology of the Internet.
This Solution Reference Network Design (SRND) publication is intended to provide a set of guidelines
for designing, implementing, and deploying Voice and Video Enabled IPSec VPN (V3
This SRND defines the comprehensive functional components required to build a Site-to-Site Enterprise
Virtual Private Network (VPN) solution that can transport IP telephony and video.
The Internet is now a household term in many countries. With otherwise serious people beginning to joyride
along the Information Superhighway, computer networking seems to be moving toward the status of TV sets and
microwave ovens. The Internet has unusually high media coverage, and social science majors are descending on
Usenet newsgroups, online virtual reality environments, and the Web to conduct research on the new "Internet
History of WDM networks.
Current Internet: Multilayer
between IP and WDM layers.
Future: IP directly over WDM

In the history of Ethernet, the virtual LAN is a recent addition. The VLAN was introduced to solve a number of networking issues. In this whitepaper you will learn about the evolution of Ethernet, the reasons VLANs were introduced, and the ways that VLANs can be used. You will also learn about the networking standards that address the VLAN implementation.
Each partition is logically isolated from the others, and must provide the same services that are available
in a traditional dedicated enterprise network. The end user experience should be as if connected to a
dedicated network providing privacy, security, an independent set of policies, service level, and even
routing decisions. At the same time, the network administrator can easily create and modify virtual work
environments for various user groups, and adapt to changing business requirements adequately.
This module provides students with the knowledge and skills to configure
virtual private network (VPN) access.
After completing this module, students will be able to:
Explain the use of VPNs and Microsoft® Internet Security and Acceleration
(ISA) Server 2000.
Configure VPNs by using ISA Server.
Virtual private networks (VPNs) are another feature that firewalls have quickly adopted. Firewalls, by the very nature of their placement in the network design, represent a natural device to provide termination for LAN-to-LAN and in some cases remote-access VPNs.
This document describes how to deploy VMware ESX Server 2.5 into the Cisco data center architecture.
It provides details about how the ESX server is designed and how it works with Cisco network devices.
The document is intended for network engineers and server administrators interested in deploying
VMware ESX Server 2.5 hosts in a Cisco data center environment.
The centralization of access to shared services provides a common point of policy enforcement and
control for all VPNs. This is referred to as the services edge functional area. Services edge has more of
a logical than a physical meaning. In a specific network design, the point of policy enforcement can be
physically located in a specific area of the network, but in certain cases, it might also be spread around
1. Private Network: Đây là 1 dạng hệ thống mạng LAN riêng biệt sử dụng địa chỉ IP để chia sẻ dữ liệu giữa các node được kết nối với nhau. Trong mô hình dạng này thì các ứng dụng và cổng dữ liệu (được sử dụng để quản lý những giao thức kết nối) được thiết kế riêng để tăng tính bảo mật.
