Network Reliability



Network Reliability

Network must have the capability to ensure that all links(Click here to learn more about connection) are up all the time. If a network isn’t reliable, then downtime will be a very common problem.
Contents:

There are 4 key points that have to be met when setting up a network
1.  Fault Tolerance – To have more than 1 connection connected to a certain place.
2.      Scalability – To be able to grow in network size and fit into the network topology/design due to increasing demands
3.      Quality Of Service – To modify the bandwidth priority of traffic so bandwidth is put to better use
4.      Security – To protect the network from intruders. Can increase the security of physical access as well as implementing extra security  system so as to beef up the network security

Fault Tolerance
We all know how dire a solution is when the network is down. Everyone starts to panic
and chaos arise. A Fault Tolerant Environment will be able to ensure that when a disaster do happen, the impact done to the equipment are kept to the minimal. This is important because it will allow faster recovery time. The damage done to the organization is also reduce greatly depending on the kind of accident that happen. There are 2 kinds of Fault tolerance
1.      Fault Tolerance in a circuit switch
·        Makes use of the load balancing concept. Have many path to the same destination. However only one path will be chosen. If the chosen path is down, remaining system will still be functioning. This allows for the network to continue as usual as if nothing has every happen.
2.      Fault Tolerance in a Packet Switch
·        Similar to circuit switch fault tolerance. The only difference is that the redundancy link is also use when there is no error. Data is usually broken up into smaller packet and encapsulated with the source and destination address. They are then send separately over and de encapsulated at the destination

Scalability
Scalability is the ability to scale up the network base on the current demand needed for the network.
This is the age of the internet where everywhere you go, you see electronic devices. Without a network that can scale up, how is it possible for the organization to grow! This is done by building a network that allows you to replicate the exact setup easily. The replication is done when you need to scale up your organization.

Quality Of Service
This refer to the priority allocated to the services in the network. This service is used so that the bandwidth can match your need. Criteria for QoS are
·        Is time a factor (Results will vary based on time)
·        Is time not a factor (Results will be the same)
·        Is it use for important matter
·        Is it necessary (You can reduce QoS if your worker is doing something unproductive on the Internet)
Depending on the situation , changing the QoS can be useful for your network in utilizing it better.

Security
This is used to ensure that the organization information is kept private and confidential. Security is used to
·        Prevent any form of damage to important data
·        Prevent loss of funds
·        Prevent leakage of information
·        Prevent loss of business (Disrupting the System)
Security is also use to
·        Maintain Data integrity. This means that the Data isn’t change once it will transmitted from the sender
·        Prevent Theft of information.

I hope you manage to understand the importance of a reliable network. If the network Is not reliable , many things can go wrong. Reliable networks makes people heart calm!
