Wireless Networking

Mobility is no longer a barrier to productivity and efficiency but now provides a true competitive advantage. Accessing real-time data whilst at a customer site, whilst travelling or whilst working outside of normal office hours now allows a more flexible and efficient approach to business processes.
Wireless networking technology, fuelled by the emergence of cross-vendor industry standards such as IEEE 802.11, has produced a number of affordable solutions that are fast becoming a realistic business benefit for all types of industries where the installation of network cabling is not practical.
802.11. A group of specifications, developed by the Institute of Electrical and Electronics Engineers (IEEE), for wireless networks that are used to manage packet traffic over a network and ensure that packets do not collide - which could result in loss of data - while travelling from their point of origin to their destination. These are: 802.11, 802.11a, 802.11b and 802.11g. Each access point typically covers 50-100 metres of open space with current specs for 1, 2, 11 and 54 Mbps. It is intended to provide for interoperability of wireless LAN products from different manufacturers. For security and privacy, 802.11 accommodates the use of Wired Equivalent Privacy (WEP), a wireless authentication protocol based on I.D. keys and bit-encryption.

Benefits for the organisation:

Benefits for the user:

• No need for training on new devices as existing mobile devices can be used.
• Freedom and flexibility in where they can work and when.
• Improved client account management away from the office as real-time data can be made available at the client site.
• Access to real-time data enabling more efficient and informed decision-making.


LAN - Local Area Network

A form of networking technology that implements a high-speed short distance method of computer communications, such as in a department, office, home or building.
Most LANs connect together multiple devices so that users can use, for example, one printer or one set of applications instead of having an individual printer or application on each personal computer.
LANs are capable of transmitting data at very fast rates, much faster than data can be transmitted over a telephone line; but the distances are limited, and there is also a limit on the number of computers that can be attached to a single LAN.
The most common wiring technology for a LAN is Ethernet, although wireless technologies are evolving. 3 types of Ethernet to consider:

Four common LAN topologies exist: bus, ring, star, and tree.




Server OS

A server is a host computer on the network that stores information and performs critical functions for a particular purpose.

Examples of types of server:

Essentially an operating system has two primary functions:




Routing is the transportation of data across a network where the data passes through at least one intermediate device.

Routing and bridging are often compared as they appear to carry out the same function. However, there is one distinct difference. Bridging occurs at the OSI Layer 2 (Data Link Layer) and utilises MAC addresses, whilst routing occurs at the OSI Layer 3 (Networking Layer) and utilises IP addresses.

Routing involves two basic functions:

Determining optimal routing paths; and
Transporting information through a network.
In the context of the routing process, the latter is referred to as packet switching.

Routing protocol uses metrics derived from path variables such as: bandwidth, cost, hop count, load and delay to discover the optimal path to a destination. Routing protocols will run these values through complex formulas to find the optimal path. This information is put into the routing table and the device is informed of which interface to use. Once this has been ascertained the router will use information in the table to route the data.



Many applications are very demanding on network links and as a result data is often inefficiently transmitted. To combat this, switches provide clear paths to and from each node whilst maintaining multiple, simultaneous data transmissions, unlike bridges and routers that process packets on an individual 'first come first served' basis.

Switching technology has therefore superseded bridging as the process of forwarding data from one segment of the LAN to another using layers 2, 3 and 4 of the OSI model. Switches are hardware based and provide enhanced throughput performance, higher port density, lower per-port cost and greater flexibility.

A switch examines the data and uses the addressing information to determine its destination. It then creates a virtual link to the destination and transmits the packet there.

A network can be segmented into VLANs - Virtual Private Networks (possibly by departmental or hierarchical groups) providing improved manageability and security.
Troubleshooting is aided through port monitoring, packet error detection, and fault isolation.
Greater network insight and manageability allows for a pro-active, rather than a reactive approach to network management, reducing downtime, and assisting with future infrastructure planning.
Tracking and isolation of issues acts as a back-up should any problems occur.
Workload and trend analysis ensures that the network is running at it's optimum performance and also highlights the impact of any changes made.
Increased functionality allows for greater flexibility, scalability and the provision of capacity reservation.
Class of Service enables traffic prioritisation through packet classification at the network edge, utilising Layer 3 and 4 information, and provides bandwidth control.


Network Storage

Businesses are required to comply with more and more data laws and regulations set by the Government and Industry. There are more than 18 different data compliance acts affecting UK companies making compliance one of the biggest challenges facing IT departments.

Data storage is no longer just a matter of retention for internal use but now regulations stipulate that some data must be kept for certain time periods and in certain cases be available within just 24 hours. Therefore, storage solutions must address how data is kept, protected, shared and retrieved. In addition to adhering to data compliance regulations networked storage enables higher availability, better network performance and increased uptime.

It is necessary to perform a business analysis to highlight compliance commitments relating to each data type. This analysis can be used to assess the best technologies for your compliance requirements. In addition to a storage infrastructure solution it is also imperative to implement effective disaster recovery.

Storage Area Network (SAN) - is a high-speed sub-network connecting storage devices and servers to provide consolidated storage and storage management. Data is not stored directly on to any of the network's servers, maintaining server power for business applications and releasing network capacity to the end user. SAN is highly scalable and can offer high system availability, extensive fault tolerance and low cost of ownership.
Network Attached Storage (NAS) - relocates storage from application servers onto its own independent platform. The server still handles the data processing but a NAS device will deliver the data to the user. By consolidating storage, resources are more scalable and manageable and hard disk storage space can be added to a network without shutting down existing severs for maintenance and upgrades.
Direct Attached Storage (DAS) - as the name suggests, is a storage device that connects directly to a single server for storage and retrieval of data and database applications or email. Performance is not as high as NAS and it requires high capital expenditure.

Economies of scale - Organisations can manage more data for less money by consolidating data across the network rather than using many distributed devices (as would be the case with DAS)
Business continuity planning - A common data location allows copies to made quicker, with less disruption and more efficient migration than with disk-to-disk or disk-to-tape methods. Improving business continuity and a providing efficient disaster recovery.
Improved management - Single point storage allows for easier data management and monitoring.
Compliancy - Data is stored and made available in compliance with associated laws and legislative guidelines.
