A mobile computing device is defined to be a portable computing or telecommunications device which can be used to store or process information.

Examples include laptops, netbooks, smartphones, tablets, USB sticks, external or removable disc drives and flash/memory cards.

The computing environment is mobile and moves along with the user.

This is similar to the telephone number of a GSM (Global System for Mobile communication) phone, which moves with the phone.

The offline (local) and real-time (remote) computing environment will move with the user.

In real-time mode user will be able to use all his remote data and services online

Routing and Remote Access Services (RRAS)Enable routing and remote access through

virtual private networking and dialup networking

Virtual private network (VPN) Tunnel through a larger network that is

restricted to designated member clients onlyDial-up networking

Using a telecommunications line and a modem to dial into a network or specific computers on a network

A mobile virtual private network provides mobile devices with access to network resources and software applications on their home network, when they connect via other wireless or wired networks

A VPN maintains an authenticated, encrypted tunnel for securely passing data traffic over public networks typically, the Internet.

RRAS Turns server into a dial-up Remote Access

Services (RAS) server capable of handling hundreds of simultaneous connections

A VPN network

VPN Uses LAN and tunneling protocolsEncapsulates data as it is sent across a public

networkBenefits of using a VPN

Users can connect through a local ISP to the local network

Ensures that any data sent across a public network is secure

Encrypted tunnel

Function of the remote access protocol Encapsulate a packetTCP/IP is the most commonly used transport

protocolEncapsulated in a remote access protocol for

transport over a WANOther legacy transport protocols

IPX for legacy NetWare networks NetBEUI for legacy Microsoft networksNot supported by Windows Server 2008

Serial Line Internet Protocol (SLIP) Originally designed for UNIX environments Provides point-to-point communications using

TCP/IPCompressed Serial Line Internet Protocol

(CSLIP) Newer version of SLIP Compresses header information in each packet

SLIP and CSLIP do not supportNetwork connection authentication

Point-to-Point Protocol (PPP) Has more capability than SLIP Remote access protocols

Point-to-Point Tunneling Protocol Layer Two Tunneling Protocol Secure Socket Tunneling Protocol

IP Security (IPsec)IP-based secure communications and

encryption standards created through the Internet Engineering Task Force (IETF)

Secure Socket Tunneling Protocol (SSTP) Employs PPP authentication techniquesEncapsulates data packet in the Hypertext

Transfer Protocol (HTTP)

Secure Sockets Layer (SSL) Data encryption technique employed between a

server and a clientPPP, PPTP, and L2TP are available in:

Windows 2000, Windows XP, Windows Vista, Windows 7

Windows 2000 Server, Windows Server 2003, Windows Server 2008

SSTP is available in:Windows Server 2008, Windows Vista,

Windows 7

RemoteAppNew feature Enables a client to run an application without

loading a remote desktop on the client computer

TS Gateway Provides a secure way to use Terminal Services

over the Internet

Routing and Remote Access Services includes Virtual private network (VPN) and dial-up

servicesRemote access protocols include:

SLIP, CSLIP, PPP, PPTP, L2TP, and SSTPUse Server Manager to install the Network Policy

and Access Services roleVPN has many properties that can be configured

Configure a remote access policy to govern how a VPN server is accessed
