What Is a Passive Optical Local Area Network?

Topology refers to the physical property of connecting two point-to-point networks using light, typically using optical fibers. The property of topology can be studied either qualitatively or quantitatively. In qualitative studies, the network topology is described in terms of fiber types, properties, and optical paths. In quantitative studies, the network topology is measured against bandwidth and performance. Qualitative studies, on the other hand, consider the utility of the network topology as a function of the input parameters.

The major benefits of Passive Optical Local Area Network technology are: it can replace copper wires; it can provide for better cost efficiency; it can help in providing for improved stability and reliability. Further, with the use of various technologies like Soft optical networking, optical transmitters can be positioned at various points along with the network infrastructure. This enables easy accessibility of signals by end-users.

The major disadvantages of implementing a Passive Optical …

System Area Networking

System-Area Networking is a high-speed, highly efficient connectivity solution. It is a powerful innovation that enables system integration and application sharing through a local area network (LAN). It is based on the technology of hop-narrow carrier-class networking. System-Area is based on four technologies; Layer 1 packet-switching technology, layer 2 multipoint communication technology, and packet switching technology. It utilizes four different transport protocols: TCP/IP, ICMP, IPIP, and TCP/IP over HTTP. There are also some security features, which are implemented to provide the necessary protection for system resources and to ensure the integrity of the data packets.

System-Area Networks has some advantages, which makes them more popular than other forms of networking. The following factors contribute to the popularity of the system-area technology. They have a compact design and provide a fast and efficient local area network for application deployment. System-Area also has some benefits that include:

System-Area Networking was designed by …

The Ideal VPN Topology

A VPN (Virtual Private Network) is a service that creates a secure, listed online connection. VPNs in essence extend a secure internal network over a public network, this should therefore enable a user to safely send and receive information across the web. The major benefit of using a VPN is the privacy it offers users; they do not reveal their IP address which can protect their information from being tracked or compromised. Another major benefit is the speed at which the network connection is established, this means that emails, VoIP calls are much faster than a normal dial-up connection. As well as these benefits, VPN also provides several other features such as enhanced security, improved stability, reduced Virtual Private Networkbandwidth usage, and improved management.

Virtual Private Network service providers often use different methods to create a Virtual Private Network. There are two types of Virtual Private Network, those that are referred to …

Advantages of a Storage Area Network

A storage area network or SAN is a logical computer network that provides remote access to unified, consolidated, block-level data storage over a local network. SANs are used primarily to access data storage devices like disk arrays and tape drives from multiple servers, so the devices seem to the operating system like directly attached storage. The network has features such as virtualization, address management, and policy-based routing, all of which allow different devices in the same network to operate in different ways. For example, while one disk drive in a local network may be connected to several other drives in a different network, a SAN has virtual networking between them. The physical address of a networked SAN is given by the manufacturer of the SAN device.

There are three basic types of SANs: enterprise, consumer, and central. An enterprise network has some storage-oriented servers that are connected through the network …

Advantages and Disadvantages of Wide Area Network Services

Wide Area Network is also known as Wide Area Network or Wide Area Linkage. It is an extension of the Local Area Network. Wide Network has several advantages and disadvantages compared to the Local Area Networks. Wide Network supports data packets of billions of bits per second (bps), much more than the Local Area Networks (LANs). The speed of Wide Area Network is way beyond the LANs and therefore makes Wide Area Networks the best option for high bandwidth data transfer.

Wide Area NetworkBroadband internet connection is one of the main reasons behind Wide Area Network. It provides a fast internet connection because of its high capacity and faster transmission over long distances. A wide Network is using to transfer a large amount of data at a very high speed and reduced expense on equipment. Various Wide Area Networks are used for communication, internet access, etc.

One Wide Area Network is made …
