Network Design Principles – Part 2

30 Sep 2018

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.

Modern Cabling System Design Trends – Part 2

17 Aug 2017

Stu Kushner

Office Cabling,New York City As discussed by Part 1, the most significant trend in IT (information technology) is the greater reliance of organizations on high-performance data communications (datacom) cabling. Part 2 will cover High Performance Cabling and Aesthetics of Cabling.

High Performance Cabling

The use of high performance cabling of copper and fiber optic cabling is influencing the design of wiring and cabling management systems. Data transmission integrity must be maintained by cable bend radius specifications. Now available are specialized fittings for raceways and other management systems that ensure minimum cable bend radius, preventing damage and maintaining effectiveness. Upcoming technologies such as 10 G/s Ethernet will result in greater demands, making it even more important that every aspect of a structured cabling system ensures high performance.

Being able to provide adequate space for the accommodation of bend radius needs to work in conjunction with the goal of being unobtrusive visually. This objective is affected by the necessity of physically separating power and low-voltage channels to prevent EFT (electrical fast transient) disturbances. Fortunately, a new raceway design maintains complete separation through crossover fittings that provide more space inside the raceway, allowing the bend radius of 10G/s cable’s larger diameter.

Aesthetics of Cabling

The design of modern wiring and cable management systems now aspire to both form and function. Non-metallic raceways with visually attractive profiles in a variety of colors are now available in the marketplace. Stainless steel is also trending, featuring plates that conceal seams. Moreover, components can be combined in matching colors and styles. This ongoing aesthetic drive has led to almost invisible activations that are recessed and flush. Poke-through devices now feature datacom ports and receptacles with sleeker profiles. Accommodating a greater number of outlets, high-capacity service activations are much less obvious than dated low-capacity fittings.

Summary

Product development for wiring and cabling management systems must unceasingly keep pace with increasingly complex datacom requirements. Solutions from manufacturers must be compatible with a wide variety of datacom cabling, allow for both system and operational flexibility, and deliver eye-pleasing aesthetics in the workplace.

Choosing Plenum Cables for Plenum Space

5 Sep 2014

Office Cabling Network Cabling, New York City The plenum space is described as that section of the building that makes possible air movement for HVAC systems. It also provides the space for conduits of heated, conditioned and return air circulation. The distance between the structural ceiling and dropped ceiling tiles is regarded as the plenum space.

The plenum space houses communication cables for telephone and computer networks. However, increasing neglect of cables in plenum areas create a major risk in case of fire.

How to Install a Patch Panel

27 Jun 2013

Stu Kushner

The process of installing a patch panel onto a wall begins with the preparing the wall to hold the rack. Most offices have drywall walls. Sometimes the walls are concrete if they lie along the structural boundaries of the building. This installation involved mounting the patch panel onto a wall that is drywall on top of concrete.

The photos below will illustrate what is involved in mounting a rack that holds the patch panel and switch.

Simplicity Reigns Supreme with VOIP

10 Jun 2011

Stu Kushner

We’ve talked a bit about just how much upgrading your current business phone system to a VOIP phone system can save you in terms of space and complexity of equipment. With voice over internet protocol there is no need for a large closet full of expensive equipment that requires maintenance or that needs expensive additions if you want to upgrade. Small businesses are always looking for ways to simplify procedures and to trim operational costs that won’t interfere with the quality of service that they provide to their customer .

Computer Network Patch Panel

Network Cabling ,Data Cabling, Cat5e, Cat6/6a Cabling A patch panel is an in-line series of connections mounted onto a frame to enable network cables to be terminated in an orderly manner. Typically, the panel is the termination point of network cabling drops that are installed in a office or residential cabling system.It is numbered and comes in 12-port, 24-port, 48-port and 96-port configurations. The numbering of the panel ports allows for the network installer to label the wallplates to match the corresponding connection at the patch panel.

Patch panels are most commonly used for computer data networks but as Voice Over Internet Protocol (VOIP) phone systems become more common, we are seeing phone systems being terminated into panels. They are wall or rack-mounted. In small offices, a 12 or 24-port patch panel might be wall-mounted to a wooden mounting board. Larger office networks will usually require a rack mounted series of panels.

The patch panel comes in Cat5, Cat5e and Cat6 types to match the cable being installed. The connections on the panel are RJ45 that are designed to allow for a cable to "punch-downed" into the connector. The connector has 8 punch down points to accommodate the 4-pairs of wires in a Cat5/6 cable.
