Use the right pipes in your network’s plumbing

September 24th, 2008

Wiring in a network is like plumbing in a house. Just as pipes form the pathways through which water flows to and from your plumbing fixtures, a network’s wiring provides the pathways through which computers transmit data using electrical signals. The amount of data that computers can move through a wiring system at any one  time depends on the characteristics of the wires, or pipes, installed. The larger the pipes, the more data the computers can send simultaneously.

You can think of a network’s bandwidth as the size of a network’s pipes. Bandwidth represents a range of usable frequencies and is measured in hertz (Hz). A higher hertz rating for a network medium means higher available bandwidth. Higher bandwidth translates into bigger pipes to carry data. Just because you have big pipes, however, doesn’t mean you always get to fill them completely. Therefore, it makes sense to try to measure the actual amount of data (called throughput) flowing through the pipes. Read the rest of this entry »

The deal with IPv6

September 24th, 2008

The new kid on the netblock is IPv6, the designated successor to IPv4 and touted as the next best thing.

Primary improvements provided in IPv6 include a much larger (128-bit) address space capable of addressing 2128 unique hosts, eliminating stopgap measures to deal with IPv4 address space limitations and enhancing security and mobility for networked computers. Despite these improvements, little actual real-world deployment of IPv6 in a general sense limits the accessibility and availability of this new protocol framework to reserved, designated working groups in the technical field.

Outside the scope of experimental and prototype networks in Europe and branches in hightech companies, nobody is really using IPv6. Not even Cisco has shifted its internal infrastructure entirely over to IPv6 yet, so it’s no surprise (to us, anyway) that not too many other organizations are charging aggressively into IPv6 deployment, either.

Winter Values - The Heart of Your Business

September 2nd, 2008

If Greater Purpose is the soul of your business, then the place where the soul rests is in the arms of values. When choices, which determine our course of action, are born from our core values, they become our life foundation. When our business actions are rooted in our deepest values, they become the heart of our business. Through your personal core values, your Greater Purpose finds tangible expression. Together, they form a safeguard. They will guide you through industry landscapes littered with lawsuits, avarice, and the temptation to grow without conscience. Values ensure that the choices you make are meaningful and grounded.

Values help to maintain the integrity of the soul of business. It is by adhering to these values, which influence the entrepreneur’s life and business, that business will be able to take its next quantum leap. Once we’ve come to realize that the cost to the soul is too great, that a simple act of cutting costs or increasing revenue without mindfulness of the far-reaching shadows they cast, longer even than our life or the life of our business, then that is when we will awaken from the fool’s slumber and take responsibility of the gift we’ve been given to co-create with a force much greater than our collective imaginations.

Your values serve not only as guideposts along the way, but also as beacons for your clients and for other businesses that you may want to interact with in the future. They become demarcation points that clearly say what you’re about and what your clients can expect of you. I believe all potential employees should have clear in their minds what their own values are when walking into an interview. Furthermore, the current employees have an obligation, when asked by candidates, to clearly articulate both their own personal values and those of the business-the two should be closely aligned.
