Network Design Principles – Part 2

Reliable & Manageable Scaling

Structured-Cabling,Data Cabling 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.

Creating the Requirements of Network Design

5 Jul 2018

Stu Kushner

Data Cabling ,Cat5e ,Cat6/6a ,Cabling ,Structured Cabling Various requirements that are skillfully combined during the implementation phase can result in a desired network design that helps attain a company’s business goals. Below is a classification of requirements for an organization. Some may be directly provided by the network design team while others may be determined from the goals or requirements of the company.

Business Goals

Decreasing operational costs

Expanding business via additional remote sites

Increasing staff productivity

Business Requirements

Decrease expenses for the maintenance of multiple voice & data networks

Provide support for expanding business via additional remote sites

Raise staff productivity by improving internal communications via mobile and video devices, while safeguarding company security

Functional Requirements

Ability to introduce and support new remote sites to the network without redesign

Infrastructure supporting data, video, voice, and wireless in a unified manner

Isolation of guest and employee wired and wireless traffic to comply with standard company security policy

Application Requirements

When an organization plans to add video and VoIP capability to their network, particular application requirements must be met. In such instances, the network design must be capable of providing sufficient network availability, efficiency, and performance for these two new features to support business goals.

Technical Requirements

In order to attain the above example’s functional and application requirements in consideration of the company’s business goals, the network design must have the following features:

High Availability – Raise the level of high availability in order to support traffic crucial to business, such as data and voice.

Quality of Service (QoS) – User experience can be greatly improved through the introduction of QoS in order to attain excellent voice and video services.

Scalability – Implement scalable network (WAN) design for supporting growth of business projected for the coming 12 months.

Security – Network security must be optimized when new features such as voice and Wi-Fi security are added.

Traffic Isolation – Provide traffic isolation to meet information security requirements.

Is Wired or Wireless Best for Your Business? – Part 2

15 May 2018

Stu Kushner

Data Cabling,Structured Cabling,Washington DC As discussed in Part 1, many users no longer think wired Internet connections are necessary because WiFi has become so commonplace in everyday use. However, hard-wired connections do have advantages for businesses that should not be overlooked. Part 2 will discuss Wireless Advantages and Considerations.

Wireless Advantages

Typically, wireless Internet connections will likely be adequate for the majority of tasks at a workplace. Lots of employees like wireless primarily because of its convenience and mobility, thinking the advantages from a hard-wired connection are not worth the trouble of attaching an Ethernet cable. In addition, advancements in WiFi technology are gradually gaining on . Even though an organization may not require Ethernet’s advantages in speed, low-latency, stability, and security, it should reconsider before going completely wireless.

Wireless Considerations

Make sure that the new WiFi equipment that your company buys features the newest 802.11 AC Wave 2 standard. It will be crucial for the future because it can support several users and handle multiple inputs and outputs (MU-MIMO).

Another benefit of 802.11 AC Wave 2 is that it gives WiFi equipment the capability of supporting multiple inbound and outbound streams. Thus, a company’s WiFi will be able to receive and broadcast data at the same time. As a result, audio and video streaming performance is improved.

The 802.11 AC Wave 2 standard will also allow your organization to implement future technological advancements. The latest devices from Apple can support MIMO over 5Ghz bandwidth, and this will eventually become the industry standard in the near future.

Conclusion

Obviously, an office can have both Ethernet and WiFi. Certain types of organizations require a hard-wired network to handle very large files, and they will also need to provide WiFi for guests, conference rooms, and outdoor areas. Always remember that Ethernet will provide better performance than WiFi for companies that need to process a great volume of data. At the same time, businesses should take advantage of advances in WiFi technology.

Data Cabling ,Network cabling, DC As discussed in Part 1, the Top-Down Approach for network design provides several advantages, especially when its implementation is business-driven. Part 2 will cover the topics of Top-Down Logic and Scope of Design.

Top-Down Logic

The top-down network design approach is capable of utilizing top-down logic in conjunction with the process of Preparation, Planning, Design, Implementation, Operation, and Optimization (PPDIOO) as summarized by the following bullet points:

Advantages Of Hard-wired Cabling Over Wireless Networks For Database Applications

5 Jun 2014

Stu Kushner

Network Cabling Data Cabling Corporate organizations need to share information efficiently. There are two options for them when it comes to setting up database applications; it is a choice between hard-wired cabling and a wireless network. Wireless systems provide users with more mobility. However, the majority of enterprises prefer the wired model for more control, security, consistency and speed. These are the major upsides of going for physical connections. It is comparatively economical since the cost of cabling, even with the lengths needed to cover a standard office space, is generally cheap.
