Mesh Network with WiFi And WiMAX

Mesh topology is not supported by existing IEEE's wireless LAN standards but it becomes popular as city-wide (municipal) Wi-Fi network deployment gains more supporters day after day. In a mesh network, each node (i.e. base station or access point) connects to several neighboring nodes and on to a mesh gateway (i.e. a base station that aggregates the mesh network traffic and routes it to the Internet). Since each node has many routes to a mesh gateway, mesh network is very reliable. But mesh network is more complex to manage and poses interference challenge especially for operation in a license-exempt band such as in Wi-Fi case.
By examining current Wi-Fi mesh network architecture, basically there are three layers. These are mesh access handling user access to a mesh node, mesh transport interconnecting mesh nodes and routing traffic to mesh gateways, and backhaul connecting a mesh gateway to an Internet PoP (Point of Presence) or other content gateways.
Backhauls for mesh Wi-Fi networks are provided using various wired and wireless solutions, i.e. fiber optic, leased line, DSL, and proprietary point-to-point (PTP) or point-to-multipoint (PMP) radio including some pre-WiMAX equipment. A wireless backhaul - specifically WiMAX - enables flexible placement of a mesh gateway node anywhere in the network, therefore it doesn't have to be located in a telco's CO or close to a fiber/DSL termination point. The portable WiMAX equipment (Base Station) also allows fast installation and easy relocation. Moreover, WiMAX was designed for outstanding performance in NLOS environment, typical in metro area with many high rise buildings. WiMAX also can operate either on licensed or unlicensed band, giving more options for operator/ISP/municipality in addressing various interference conditions and users' requirements.
The mesh transport layer provides the interconnection between mesh nodes. There is a project in the IEEE to standardize Wi-Fi as an intra-mesh transport solution, but the work is still in progress. The current established Wi-Fi solution uses proprietary technology developed by each vendor which might cause interoperability issues in the future. WiMAX can naturally replace Wi-Fi in this layer, interconnecting mesh nodes using standard equipment based on the IEEE 802.16-2004 or 802.16e which includes support for optional mesh topology. Besides, WiMAX has built-in QoS support and is optimized for longer distance (WiMAX is a wireless MAN while Wi-Fi is a wireless LAN) .
For mesh access layer, at present users connect using their Wi-Fi-enabled laptops, PDAs, or smart phones. WiMAX integration into such portable/mobile devices is still in its early stage of development. However, in several months/years to come one may expect the emergence of dual-mode Wi-Fi/WiMAX devices and network adapters (NIC, PC card, PCI Express) which can connect automatically to any available network with the best signal.

How To Disable Delete Confirmation Dialog Box
 

Today tip is very useful particularly for those users who want to restrict the common users to shutdown public computer in common areas.  You can disable the "Turn off Computer" button on the start menu and a common user will not "Turn Off, Restart and Stand By" a computer. Using registry editor, you can implement this task in all windows XP versions with minimum effort. 

Follow the given steps to disable Turn off Computer" button on the start menu:

To use this feature, you will need to be logged into your computer with administrative rights.

Click Start button and type regedit in Run option then press Enter for next.

Disable the Security Center warnings
Security is a system of safeguards designed to protect a computer system and important data from damage or access by unauthorized persons. Different antivirus and firewall programs are used to manage the security of the computer. Some time this is build-in antivirus or firewall program in windows XP to maintain the computer security. But if your windows is not provided with any antivirus, firewall program and Automatic Updates, your windows security center will alerts you a message "Your computer may be at risk. Your virus protection status is unknown" with useless repeating reminder. You can disable this message permanently by changing the values of “AntiVirusDisableNotify” in windows registry.

• First click on Start button then type Regedit in Run option.

• Here locate the location to:

·         HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center

• Here in right side panel, double click on AntiVirusDisableNotify and set its value 1.

• Now close the registry editor and restart your computer after any changes to go into effect.

Learn How to Enable a Cisco IPSec VPN client To Connect To A Cisco VPN Concentrator Through ISA Server 2000

 

Provide Support for the Cisco VPN Client

In most cases, IPSec VPN traffic does not pass through ISA Server 2000. However, Cisco Concentrator 3300, with the latest firmware updates, uses "transparent tunneling" that uses User Datagram Protocol (UDP) ports 500, 4500, and 10000 to communicate securely between VPN clients and concentrators.

To provide support for this configuration, create the following protocol definitions:

Note The client computer must be configured as a SecureNat client.



By creating these protocol definitions, you enable the SecureNat client to connect to the Cisco VPN server through ISA Server as all traffic is passed as UDP traffic. According to the Cisco Transparent tunneling technology, this traffic can traverse Network Address Translation (NAT) firewalls.

Note You must make sure that your Access Policy permits these three custom protocols.

Create the Protocol Definitions

Create the new custom protocols to enable the transparent tunneling feature. To do so, follow these steps:

1. Start the ISA Management snap-in. To do so, click Start, point to Programs, point to Microsoft ISA Server, and then click ISA Management.
2. Under Policy Elements, locate the Protocol Definitions container.
3. Right-click Protocol Definitions, point to New, and then click Definition.
4. In the Protocol definition name box, type a descriptive name for the definition (for example, type Port 500 UDP Send Receive), and then click Next.
5. In the Port number box, type 500. In the Protocol type list, click UDP. In the Direction list, click Send Receive (do not click Receive Send), and then click Next.
6. Under Do you want to use Secondary connections?, click No, and then click Next.
7. Confirm your settings, and then click Finish.
8. In the left pane, right-click Protocol Definitions, point to New, and then click Definition.
9. In the Protocol definition name box, type a descriptive name for the definition (for example, type Port 4500 UDP Send Receive), and then click Next.
10. In the Port number box, type 4500. In the Protocol type list, click UDP. In the Direction list, click Send Receive (do not click Receive Send), and then click Next.
11. Under Do you want to use Secondary connections?, click No, and then click Next.
12. Confirm your settings, and then click Finish.
13. Repeat the steps above to create the protocol using a value of 10000 in steps 9 and 10.

The new custom protocols are listed in the right pane under Available Protocols.

Create a Protocol Rule

Create a protocol rule to allow access using the new custom protocols that you created. To do so, follow these steps:

1. Start the ISA Management snap-in. To do this, click Start, point to Programs, point to Microsoft ISA Server, and then click ISA Management.
2. Under Access Policy, locate to the Protocol Rules container.
3. Right-click Protocol Rules, point to New, and then click Rule.
4. In the Protocol rule name box, type a name for the rule (for example, type Allow Cisco IPSec VPN Client), and then click Next.
5. Click Allow, and then click Next.
6. In the Apply this rule to list, click Selected protocols.
7. In the Protocols list, click to select the check boxes that correspond to the three custom protocols that you created earlier, and then click Next.
8. In the Use this schedule list, click the schedule that you want to use when allowing these protocols (for example, click Work hours), and then click Next.
9. Under Apply the rule to requests from, click Any request (unless you want to restrict these protocols to certain client address sets), and then click Next.
10. Confirm the configuration selections, and then click Finish.

The new protocol rule is listed under Available Protocol Rules in the right pane.

Note After you perform the steps to add UDP Port 10000 as a protocol definition, you may also have to add UDP port 20000 to be able to work with some of the newer Cisco VPN Concentrators.

Note This article is designed for SecureNAT clients. You must remove the ISA Firewall client software.
