Reliable & Manageable Scaling

Scalability is a crucial characteristic that must be considered by network designers.

In addition, a network should also be reliable and manageable, which promote stability.  A network may be capable of expanding to several thousand routers. However, if there is a failure of some sort that causes instability due to greater processing and CPU usage required to compensate, the design won’t be successful.

A scalable network that is a challenge to manage or troubleshoot is also unacceptable.

Network problems that arise would take an excessive amount of time to address and repair, negatively impacting an organization’s business goals of the organization.

Thus, a scalable design must provide a manageable and reliable network.

Combining scalability, reliability, and manageability as the qualities of a network is a challenge. As a network expands, it becomes more complex, making management, maintenance, and repair more difficult.

Fault Isolation & Simplicity

Providing fault isolation boundaries creates fail-stop behavior for the wanted fault model. Fail-stop prevents faulty behavior from propagating past a fault isolation boundary. Effective network design must prevent a failure in one domain from spreading to other domains within a network. This is essential for the avoidance of unneeded processing and delays throughout the whole network because of a device or link failure. In addition, this will result in a converging network that has more stability, reliability, and speed.

The above concept also promotes simplicity as a network architecture characteristic, which decreases complexity in operations. Typically, fault isolation stops the propagation of network fault information across several domains or network areas. This will lead to greater network stability and the minimization of recovery time after failures.

The negative consequences due to a failure of a link or network node may spread to all devices across a network, resulting in a large volume of unneeded processing. A properly designed network using the Fault Domains Principle with its logical separation will limit the negative impact to within one fault domain.

As discussed in Part 1, the performance issues of your company’s network may be directly related to improper cabling. Part 2 will discuss Compatibility, Patch Cords, and Poor Installation.

Compatibility

Issues occasionally arise when coupling cabling and connectivity from various manufacturers. The use of jacks from one manufacturer with cabling from another, and then patch panels from a third firm is an example. This combination may result in compatibility problems. When components that are not intended by design to function together are used, network performance issues will likely result.

Purchasing top of the line high-performance cables, while utilizing lower-quality connectivity components, will produce a weak link in the chain. Cable of the highest quality will be unable to attain its full performance potential when it is married to jacks, patch panels, and plugs that are not rated to support its capabilities.

Patch Cords

Patch cords may be the top reason why there are issues in network performance.

Your company may have installed a high performance cabling infrastructure of the highest quality, but if low-quality patch cords were purchased to economize, network speed, signal quality, and overall performance will be compromised.

Poor Installation

Vetting the cabling services team you hire is perhaps the most important factor in the prevention of network performance issues. Check that the company you are considering has technicians that are properly trained and certified to install the cabling system you have chosen.

When cable installers are not properly trained, it will greatly increase the probability that your company’s structured cabling system will not be properly installed. Incompetent installation can result in problems such as improper pulling, excessive bending, and cable being installed too near sources of signal interference like large motors and machinery.

Poorly trained technicians will leave cabling that is not properly terminated or correctly polished. Sloppy work and insufficient attention to detail during installation will usually result in poor network performance, along with costly and time-consuming efforts to address the problems the substandard work caused.

Your employees are dissatisfied by their company’s network performance, and it is affecting their productivity. A number of factors must be taken into consideration. How many users are attempting to use resources simultaneously? Have you taken into account how much the use of devices has grown? Is your network equipment sufficient to meet demand? Answering the above questions will help, but network issues may be directly related to your company’s structured cabling.

Outdated Cabling

In many instances, the age of your structured cabling system may be responsible for poor network performance. 15-year-old cabling may have met standards when it was installed, but now it may be unable to handle the ever increasing network traffic needs of your company.

An internet service provider (ISP) provides the cable that provides the connection from your company’s network to the internet. When this backbone component fails to meet today’s bandwidth standards, bottlenecks may occur.

In situations where you are attempting to operate at speeds that are too high or carry excessive bandwidth via a cable that not rated for the capacity, it will be noticeable to users and their productivity will decline, hampering business operations.

Quality of Cabling

Cabling manufacturers rate their cables in terms of capability and performance. For example, CAT6 and CAT6a cabling have different capabilities, CAT being an abbreviation for category. A manufacturer must meet the performance standards set by the Telecommunications Industry Association (TIA) for each category of cabling.

Cabling that exceeds minimum standards will attain higher network speeds without having to upgrade your cabling. In contrast, for cabling that only meets the minimum standards, the company network speed will be unable to expand much beyond the rating of the cable.

It is helpful to understand cable standards and ratings. Even though a cable is labeled Category 6A, it is not automatic that it meets the minimum performance standards of this category. The brand name and manufacturing quality will play a big role in the cable’s output.
