The Principles of Network Design – Part 3

24 Mar 2018

Network Cabling, computer,cablingAs discussed in Part 2, Top-Down Logic is used for the process of Preparation, Planning, Design, Implementation, Operation, and Optimization (PPDIOO). In addition, network designers must determine the Scope of Design prior to the collection of data and planning. Part 3 will cover Business Requirements, Continuity, and Elasticity.



Requirements


Figuring out what an organization needs requires having an understanding of its current objectives, mission statement, and future plans. Knowledge of these should guide the business-driven aspects of the network design. Using a top-down approach, a business’s goals, drivers, requirements, continuity, and strategy will determine its business applications, technical and functional requirements, and network infrastructure solutions.



Continuity


Business continuity is a company’s ability to continue doing business after a system outage caused by a man-made or natural disaster that has damaged a data center. An organization needs a disaster recovery plan to develop its resiliency in the face of such disasters. Various parts of its network may need to be more resilient due to regulatory compliance.



Elasticity


Elasticity is an organization’s level of flexibility when responding to business developments. This typically refers to a change in business objectives or conditions, including growth, recession, merger, acquisition, etc. Therefore, a company’s network design must have adequate flexibility in order to fulfill its business requirements and strategic goals. A designer’s comprehension of the overall trends of the organization’s business sector will provide valuable guidance in the design’s features that provide flexibility.


The design of a network must give an organization the flexibility that will allow it to perform integrations with other networks. This will usually be required when mergers and acquisitions take place. It is important to note that during a merger or acquisition, the network may undergo considerable growth during a very brief period. In such circumstances, the most daunting challenge for network designers is having to handle the various design principles, conflicting control plane protocols, and overlaps in IP address spaces of the networks being integrated.


Part 4 will cover “How IT Enables Business Innovation.”

Is it Time to Upgrade Your Network Infrastructure?

21 Sep 2017

IT support, network infrastructureYour company will need to upgrade because network traffic is rising dramatically due to the rapid increase in the number of devices and videos online. By 2020, the number of devices will approach an estimated 12 billion. The following are reasons why you should contact an expert and experienced structured cabling support team to evaluate and improve your network infrastructure.



High Maintenance


The addition of the latest technology often stresses aged infrastructure, resulting in more downtime and troubleshooting. This increased time and effort devoted to this task prevents your IT support from working on implementing innovative solutions that may increase productivity or decrease costs, slowing your company’s growth. Installing up-to-date infrastructure will decrease maintenance and increase deployments.



Inadequate Security


Cybercrime is growing ever more prevalent and complex. Hackers tend to avoid networks with strong security and target those with weak protection. Older network infrastructure will have more and greater vulnerabilities. Modern network solutions now feature intelligent sensors and enforcers, improving security.



Mobile Employees


Today’s workers want the ability to work anywhere and anytime. Unfortunately, aged infrastructure will not be able to cope with new mobile solutions and enterprise cloud applications. In order to maintain and increase employee productivity, a network upgrade replacing obsolete equipment will probably be necessary.



Slow Network


Networks of the past were not designed to meet the current requirements of companies and their workers. Wireless technology now permits employees to work anywhere with wireless access points nearing 7 Gbps, more than 11X faster than the 802.11n standard.



The Competition


A network infrastructure upgrade will allow your company to remain competitive because it will be able to implement the latest solutions that boost productivity and earnings. Powerful applications that would have crashed your old network can now be handled, allowing your organization to keep up with competitors.

Cable Management ,Data Cabling ,Cat5e, Cat6/6a Cabling

As mentioned in Part 1, the wired industry continues to grow despite the trend towards wireless communications during the past decade because of security concerns. Concrete trenching and floor decking were discussed as two of the four main practices of cable management. Part 2 will discuss Overhead Cabling/Cable Drops and Underfloor Cable Management. Consult with experienced professionals to make your cabling project a long-term success.



OVERHEAD CABLING/CABLE DROPS


Deployed within single-story and multi-story buildings, overhead cabling provides flexibility. This method uses overhead space, which can either be a dropped ceiling or an exposed ceiling. Cables and conduit are suspended from the ceiling, and cable drops, which are concealed by chaseways or poles, descend to serve work areas.



Advantages


This method does not require any cutting or trenching of concrete cutting. Unoccupied areas are used to install conduit and cabling.



Disadvantages


It will be a challenge to reroute cabling as technicians will need to use a ladder all along a line. Cable drops are generally considered an eyesore, and so this practice is highly discouraged for facilities that emphasize customer experience, such as retail. It may not be appropriate in the work areas of certain professions such as law offices.



UNDERFLOOR CABLE MANAGEMENT


Utilizing access flooring for the routing and concealment of cables, underfloor cable management may be the most advantageous. Cables can be routed beneath the flooring or within the floor itself in low-profile access flooring.



Advantages


Underfloor cable management does not require concrete cutting or trenching. It is not necessary to work inside ceiling space. There is flexibility in routing, and cable rerouting is easy. Low profile floors are only one to three inches in height. There is almost an unlimited number of possibilities for layout designs. It can be rapidly installed during construction, and business disruption is minimized whenever additions and changes need to be made.



Disadvantages


The method takes up space of one to three inches in height. There will be an extra step in the installation process.

Overview of Cable Management Practices – Part 1

20 Mar 2017

Although the last ten years have been trending toward wireless, the wired industry continues to grow. For security reasons, military, tech, government, and financial organizations forbid data transmission via wireless on premises. SMEs (small and medium-sized enterprises) also consider wired communications more secure, and it is the medium used for delivering power as well.


The following will discuss the four main practices of cable management and their advantages and disadvantages. Part 1 will discuss Concrete Trenching and Floor Decking. Consult with experienced professionals to make your cabling project a long-term success.



CONCRETE TRENCHING


Mostly utilized within single-story buildings, concrete trenching is made up of channels carved into the concrete subfloor through which run cable and conduit. During construction, trenches are occasionally created during the concrete pour. However, they are must be cut into the concrete subfloor with a concrete saw.


After cable and conduit are laid, the installation of floor boxes is the next step. For safety, trenches may be filled with concrete after the electrical system is installed.



Advantages


A traditional method that is very well known, concrete trenches do not take up additional space for their installation inside a building.



Disadvantages


The installation of concrete trenching is comparatively expensive, and it is noxious and noisy. In order to install trenches and cabling, the building will need to be closed during construction. Structural engineers need to be consulted to ensure a building’s structural integrity. Companies leasing a building must also receive the approval of the property management firm. As the layout is “permanent”, additions and changes may also require the patching of trenches that are no longer needed.



FLOOR DECKING


Usually found within multi-story buildings, floor decking involves running electrical conduit through the ceiling underneath the floor that it will serve. Tunnels for the conduits are cut or drilled into the concrete, and space is provided to accommodate outlets and electrical boxes.



Advantages


A traditional method utilized in multi-story buildings, floor decking does not take up additional space. In comparison to concrete trenching, much less cutting of concrete is necessary.



Disadvantages


The process of installation during construction is very time consuming. The layout is quite inflexible, making additions and changes, such as the rerouting of cables, very difficult. These will cause disruptions and hurt business continuity as two floors will be affected during the process.

General Floor Space:



  • Quad drops in each office and cube in the technology area

  • Dual drops in all other offices

  • 6 drops for cable t.v.

  • Wall facing outside is already dry walled and insulated


Part of that wall has large window with wall space under it. Customer is unsure if drops will go there or anywhere along that outside wall.

Includes the outside wall. They’re not sure if there will be drops along this wall. If so it’ll be interesting because of the insulation. Also note that they MAY want drops under the windows along this wall.

There are some pictures of the ceiling details. Also note that the client will already have cabling runners ceiling mounted down the middle of the two main hallways to the server room.



























Special Fiber Optic Line Item Bid:


US Court of Appeals wants this as a line item so they can choose to add this work or not when they’re doing the budget.

Fiber runs between floors. The floor plan represents the 6th floor. 14 runs broken out as follows. A single 6-strand fiber cable will be run from the 6th to each floor in the table below. Three strands will be connected and three will be left as spares.
