Software-as-a-service takes the onus for upgrades, data and server maintenance, installation etc off of the end customer and makes it part of the value the company receives from the software vendor.

The data generated by the end users is said to live “in the cloud”, which refers to a data center or hosting facility managed by the SaaS vendor.  This means it is consolidated and all accessible from one place, instead of being resident in partial form in multiple PC hard drives across the network.

Given the success of Salesforce.com, many other SaaS model companies are popping up with great value propositions and solid offerings. Some of these are security-as-a service offerings which provide added protection for enterprises that don’t want to maintain these applications on site.   Still others, such as startup HealthHiway which focuses on hospital patient data and billing are adding value by managing business critical, data intensive functions that used to be managed via on premise server banks and resident applications.

What does this mean for your network?  First of all, a fast WAN connection so that data can be retrieved quickly is going to become essential in the coming years.  This means your “pipe” leading into each enterprise building must be capable of handling lots of data (cat 5e or better is recommended), and your relationship with your service provider will be mission critical.   Be sure to choose a package and provider who can handle ever growing traffic needs.

Last but not least, this means that your need for new servers and personnel to maintain those servers will be reduced by the extent you choose to embrace the new SaaS models for your business.   This will allow you to focus on the business, and less on maintenance intensive activities.

If your infrastructure is not up to the SaaS challenge, now is the time to call professional structured cabling installers to make sure you can take advantage of this exciting, new trend.

One of the most common problems can be solved with a new cable or connector – if intermittent or dropped communications are happening, check the wiring with a cable connector to see if a short or connector problem exists.    Dust on fiber optic connectors can also cause problems by interfering with light transmission.

Another common problem manifests as slow connectivity due to a jabbering network card transferring lots of useless data.   Check to see if the transmit light is always on to see if a card internal to a PC or laptop is jabbering.  This happens when the card is stuck in the transmit mode – and the fix is to swap out cards.

When configuration changes are made or new pieces of equipment are added to the network, equipment set up mistakes, DNS configuration errors, WINS configuration errors or other configuration problems can result – causing network issues.   It also pays to look at router tables to see if duplicate IP addresses exist, which can cause slow or intermittent connectivity.

Wireless networking problems can be even more elusive than all this.  If you suddenly notice that your connection has slowed down and you are moving – stop.  Usually you have wandered too far away from your router and signal strength is low.  Another reason is that too many people are trying to connect to your network at once.  Many small companies don’t believe in setting up a WEP or WPA key to protect their networks, and usurpers find ways to steal bandwidth and connections run slow.  Don’t let this happen to you!  Protect your network and vital bandwidth as soon as possible.

Other issues to look for with wireless networks include interference from cordless phones, microwaves and other wireless networks in the vicinity.   Dead spots can also be an issue, and can be remedied by using a range extender or repeater if moving your router doesn’t work.

When all else fails and your troubleshooting efforts have not worked, calling in professionals with superior equipment is the right thing to do.  The right network cabling installers have the right people, the right troubleshooting tools, and the right prices for any job you may need help with.

First of all, are you experiencing any problems with dropped Internet or VoIP connections?  If so, this is a major red flag telling you that it is time to take a look at the infrastructure.   If not, but you want to upgrade by adding VoIP endpoints, more computers or more networked devices, it is also time to take a look at the network.

The first thing to look for is what type cable is installed.   In order to operate a best practices network today, at least cat5e cabling is recommended.  If you are planning to add endpoints or have issues and don’t have cat5e, then it is best to put an infrastructure overhaul in your budget and roadmap.   

Next, take a look at the terminations.   Does each cable end have a properly terminated connector?  Are wires frayed?  Torn? If so, it pays to have a professional come in and repair the terminations so no problems occur in the future.  Also look at the condition of the insulation surrounding each cable – if it is in bad shape, then chances are you have a less-than-well-shielded data pipe at that point in your network.

Next make sure that you have enough Ethernet drops to support your future expansion plans.  If not, perhaps a few more drops are necessary only – without a full network upgrade. 

Are any wires running close to sources of interference, such as fluorescent lights?  If so, it makes sense to reroute them, or pull them and replace them with fiber optic cabling if rerouting is impractical or impossible. 

No matter whether you choose a major overhaul or simple upgrades, hire professional structured wiring installers. The right professionals will perform the above assessment using the latest network analysis tools, and will quote you a fair price for just what needs to be done and no more.   Why not call them today and start moving your building towards the future?

Three kinds of virtualization are now being deployed in the data center – storage virtualization, network virtualization, and server virtualization.

In storage virtualization, physical storage devices are pooled from many network storage devices to give the appearance of a single device, managed from a central source. Storage area networks or SANs use this technology extensively.

Data installation centers of the past were filled with racks and racks of power hungry servers, taking up valuable space and generating heat.  Today’s data centers use server virtualization as a way of consolidating many “virtual” servers (referred to as virtual machines) into one piece of equipment.   Therefore, modern data centers have lowered power requirements, lowered space requirements and the ability to have needed redundancy without additional Capex.

Virtual servers are created via the use of special software that effectively partitions a system into virtual areas that act as unique,stand-alone devices.  Each virtual machine is fully capable of running its own OS (operating system), making virtual machines a great way to test new OS’s or OS additions.

Last but not least, today’s data centers are using network virtualization as well to reduce costs and increase efficiencies.  The simplest form of network virtualization is the use of VLANs – pioneered by Cisco Systems.   In a VLAN architecture, a systems administrator can configure systems that are attached to the same network as different virtual networks.   He or she can also combine separate local networks into a VLAN that can span an entire large corporate network.  VLAN architectures are sometimes referred to as “external network virtualization”.  Some newer architectures are now available featuring “internal network virtualization”.   This usually is configured via containers or pseudo interfaces which creates what some vendors refer to as a “network-in-a-box”.

The end result of the tremendous upsurge in these three forms of virtualization technology is a dramatically streamlined data center – capable of meeting the challenges poised by cloud computing and our ever-growing needs for storage and information access.

First of all, VoIP requires a good quality Internet connection – an asymmetric DSL connection to a small business, which is common, is usually not enough to run multiple phone lines without having some quality issues in the slower direction.   A T1 line, symmetrical business quality DSL, or higher speed cable modem is best for overall voice quality.

Secondly, VoIP connections can suffer call quality issues if there is no QoS or “Quality of Service” priority scheme built into the networking equipment used.  If voice is not prioritized over data, someone downloading a huge file in the next room or playing YouTube videos can cause a call to become very degraded or even dropped.

When choosing an Internet service provider, be sure to tell them that you plan to operate VoIP so that they give you a service that is designed for voice – otherwise, you may have issues such as packet loss that can also create gaps in the speech that you hear.

Choosing good VoIP phones is also critical to good quality and service, as well-designed phones have many features designed to make the overall VoIP experience as close to land line quality as possible. A good phone will have a good quality echo cancellation algorithm built into the chipset used, and will have a well designed headset with additional noise reduction features.  Cisco, Avaya, Nortel, and Shoretel all have superior products used by many businesses today.  Analog telephone adapter technology has also come a long way in the past several years – which means you can have a VoIP system using your old phones by simply buying boxes from Dlink, Linksys/Cisco or any number of other vendors and simply plugging them in.

A solid infrastructure built using at least cat5 Ethernet cabling is also a prerequisite for any business-class VoIP deployment.   If your infrastructure is not solid, or cabling is not run properly, high levels of interference or packet loss can cause your calls to be spotty or even inaudible.

The right structured cabling installers will be more than happy to do a detailed analysis of your network infrastructure and make cost effective yet useful recommendations for enhancements that will help keep your new VoIP system running efficiently.  Why not call them today?

Originally created by the CCTA under the auspices of the British government, ITIL defines a supplier independent methodology including a set of operational management procedures that have been tried and tested over a 20 year period.

ITIL forms the basis of many supplier service offerings, and three levels of certification exists for those proficient in ITIL; Foundation, Practitioners, and Managers.

A full description of ITIL would span many pages as the current release contains 30 volumes – but there are a few central concepts that are key.  One is the concept of Incident Management, where an incident is defined as any event that is not part of the standard operation of the service which could cause either an interruption of the service or a reduction in the quality of the service.  Incident management focuses on restoration of normal service as quickly as possible with as little impact as possible.

Another central concept is known as Problem Management, which simply means finding the root cause of incidents so their impact is minimized.  Problem Management is more proactive than Incident Management, and focuses on trend analysis, targeting support action, and providing critical information to the organization in the resolution of incidents.

Yet another key concept is that of Change Management, which focuses on making sure that standardized processes and procedures are used when changes are made to the network and services offered.  When proper Change Management is implemented,  minimal disruption of services and efficient utilization of resources result after any changes are made.

When choosing a service package for your network,  the choice of one based on ITIL will ensure that you get a standardized approach based on many years of knowledge and experience, as well as a process that is repeatable.    Choosing a certified practitioner or making sure that certified personnel are available from your service provider is a wise choice for your network.

If you are setting up a new network, it makes sense to review the basic ITIL literature to ensure that proper procedures are set up for its management.

We all know how signals travel over copper – but how does fiber optic cable work?  The main reason for its superior performance is that it converts the signals being carried into light before transmission, and converts them back again on the other end.

Fiber optic cables are very thin glass wires (some are made of plastic) that are arranged in bundles or optical cables.  Each fiber has a core or thin center where the light is carried, a cladding that reflects the light back into the core, and an outside coating called a “buffer” that protects the fiber from damage.

Each bundle is again protected by an outer coating, called a “jacket”.

The light signal can travel at longer distances than electrical signals can travel over copper, as it bounces back and forth from the cladding which is reflective and doesn’t absorb any light.   The only thing that degrades the signal as it travels is impurities in the glass (or plastic), which is why it is a good idea to use high quality cabling if using fiber optics for long runs.

The light is sent across the cable using a transmitter, which is usually a laser or LED that is placed very close to the fiber.  On the other end, a photodiode receiver detects the light signal, decodes it, and turns it back into an electrical signal that can be read by a computer or piece of networking equipment.

Fiber optic cabling is thinner than copper wire, and can be run in tighter places than copper.  It also uses less power, so is “greener”.

Because these cables are thinner, more of them can be bundled together to increase the overall carrying capacity, making fiber optics a great choice for service providers such as AT&T Uverse with an IPTV offering.

Fiber optics are also very flexible, which is why they are used in medical imaging where they must bend in order to get good pictures of internal organs.   Because glass doesn’t emit electromagnetic energy that can be “sniffed”, fiber optic cabling is also much more secure than traditional copper in network cabling.

The first step in making this critical choice is to assess the size and strength of your internal IT department.   If your network stability is critical but your staff small or inexperienced, then choosing a “high touch” contract makes sense. However, if you have a large network and very experienced staff, then contracts that focus mostly on rapid equipment replacement and warranty may be the best option.  Warranties are becoming richer – with many equipment providers offering advanced replacement and technical support as part of the overall package.

Today, many resellers and equipment providers also offer remote monitoring service packages that can reduce downtime and provide significant ROI even when experienced IT staffing is present.  Remote monitoring tools can help pinpoint network problems before they occur, flagging the need for equipment replacement, troubleshooting, or repair before any business impact from downtime can be suffered.

Many service contracts also include access to knowledge bases or highly trained support personnel, which makes a great deal of sense no matter what the staffing levels as key equipment knowledge can save a great deal of time and trouble when problems occur.

Another step that should be taken before choosing your best option is to list out your ideal set of services.  If you have a large enterprise or network, then an automated installed base management system may be desirable as it will allow your service provider or supplier to pinpoint where equipment is located, making next day replacement service easier to implement and meet.   If you have sophisticated pieces of equipment such as telepresence systems, then on-site engineering support may be another desirable feature.

Once a list is developed – the next step is to assess your overall budget for IT support, and compare it to the pricing offered for the services you have chosen.  This may be an iterative process for some time until the optimum balance is reached.

Over time, as your internal capabilities expand, contracts can be lessened. On the other hand, it may be more cost effective to use external resources than to maintain a large IT department.   There is no substitute for performing a solid financial analysis when making these types of decisions – no matter how large or small your network is.

One new gadget that promises to do so is a dual mode cell phone/WiFi phone that switches to a WiFi network when one is available.  WiFi networks within your company walls are free, meaning cellular minutes used can dramatically decline.

Today, dual mode phones are available from companies like Linksys, Nokia, and D-Link.   T-Mobile offers service that includes both cellular coverage and wireless hot spot access to accommodate such phones.   Data access is also made more readily available on such dual enabled phones, allowing users to listen to streaming broadcasts as well.

What’s the downside?  WiFi technology is not really designed to allow true mobility.   When on the WiFi network, there will be handoffs from access point to access point as the user moves around.   There will also be handoffs from the cellular network to the WiFi network and back that can cause calls to drop.   This can create some issues with business communications, imagine a dropped call as a customer is detailing his multi-million dollar order!

The good news is that lots of work is being put into making these handoffs more seamless and transparent to the user.   This means the future of dual mode phones is quite bright.

In the meantime, this may be a great idea for sales people who spent at least some of their day in an office equipped with WiFi, as calls during this part of the day will be free.

Taking advantage of this new technology means having a robust internal WiFi network with few dead spots and strategically positioned access points so that dropped calls are few and far between.   And these access points should be based on a robust and well planning internal network with a strong wired foundation, based on at least cat 5e cabling.

If your internal networks are ready for an overhaul so you can add these phones to your internal IT structure, why not call professional network cabling experts?  The right professionals will be happy to analyze your network and make concrete recommendations for enhancements that will move you into today’s world.   They can provide a network assessment and upgrade, and then help you choose the best dual mode phones for your team now and in the future.
