      Wireless traffic is considered to be those Internet protocol packets that are transmitted through an 802.11a, b, g, n, or i wireless protocol. Monitoring Requirements There are a few things to consider when planning to setup wireless traffic monitoring. First, the user must determine what kind of traffic will be monitored. Is the traffic to

      South Korea developed the WiBro (Wireless Broadband) technology in order to provide a high speed Internet solution for local consumers. The technology is based on the 802.16e standard which is more commonly known as the WiMAX standard in other countries. At the time of this writing, the capacity of the WiBro connections available in South

    • VLAN (Virtual Local Area Network)

      VLAN (Virtual Local Area Network)

      VLAN (Virtual Local Area Network) is a logical local area network (or LAN) that extends beyond a single traditional LAN to a group of LAN segments, given specific configurations. Since a VLAN is a logical entity, its creation and configuration is done completely in software. How is a VLAN Identified? Since a VLAN is a

    • Fiber Optic Patch Panel

      Fiber Optic Patch Panel

      Fiber optic patch panel, also known as the fiber distribution panel, is used mainly in fiber optic cable management. It helps network technicians in minimizing the clutter of wires when setting up fiber optic cables. It terminates the fiber optic cable while providing access to the cable’s individual fibers for cross connection. They are also

      Understanding the Cisco Three-Layer Hierarchical Model

      Understanding the Cisco Three-Layer Hierarchical Model Hierachical network design helps us to make networks more reliable and predictable. Level by level design help to understand networking factions easily like, we can use tools like access lists at specific level and can avoid them from others. Cisco layer model consist of the following three layers. The

      How fast is ADSL Speed?

      ADSL (Asymmetric Digital Subscriber Line) options are available in many locations. The speeds will vary for the service in many ways depending on several factors. The reason why it is called an Asymmetric Digital Subscriber Line is simple, as the speed for downloads will be significantly faster than the upload speed. This is because consumer DSL services are

    • IP Address Spoofing

      IP Address Spoofing

      IP address spoofing denotes the action of generating IP packets with fake source IP addresses in order to impersonate other systems or to protect the identity of the sender. Spoofing can also refer to forging or using fake headers on emails or netnews to – again – protect the identity of the sender and to

    • Static Route

      Static Route

      A static route is one that a network administrator creates manually. The opposite of a static route is a dynamic route. Dynamic routes are created by routing protocols. Static routes have advantages and disadvantages when compared to dynamic routes. Advantages of Static Routes: Easy to configure No routing protocol overhead Disadvantages of Static Routes: Network

      DNS (Domain Name System)

      Domain Name System (DNS) is an Internet Engineering Task Force (IETF) standard name service which enables applications and users to connect to hosts in TCP/IP based networks by specifying a name. DNS makes it possible to assign domain names to organizations independent of the routing of the numerical IP address. DNS is a hierarchically distributed database that creates hierarchical names
