By Patrick Hunter — Wi-Fi has undergone numerous iterations in its lifetime. In fact, we’ve seen no less than 16 different standards issued by the Institute of Electrical and Electronics Engineers since 1997, the year the standard was initially released. IEEE 802.11

By Patrick Hunter — In the spirit of our proactive network maintenance issue this season, it just makes sense to talk about the importance of care and feeding for our inside networks as much as the outside plant.

It’s actually very powerful in what it can teach us and requires very little in terms of high priced technology. I am of course referring to the “Traceroute” utility.

By Patrick Hunter — This is where the magic happens in routing protocols. When a network is so large that manually configuring static routes every time there is a change, the task is beyond daunting, it’s darn near impossible. Dynamic routing protocols take care of all the work for us thankfully.

By Patrick Hunter — For a refresher, Ethernet was standardized as IEEE 802.3 in 1983. Remember, the standard covers both physical wiring and signaling standards at Layer 1 of the OSI model as well as functionality at Layer 2, the data link layer. Now let’s dive in.

By Patrick Hunter — From the perspective of the customer’s Internet service, the cable modem doesn’t have an IP address and does not route IP packets. But we do know that the cable modem has a NIC to which the customer’s computer is connected. So, if it has a NIC, then it has a MAC address as well! But remember, when we discussed the fact that the customer’s computer would have the MAC address of the default gateway as the destination MAC address

By Patrick Hunter — That’s what I propose to offer you here over the next few installments: a cable perspective from the ground up on what all of that means and how they are interconnected, and most importantly, why any of it really even matters at all.

By Patrick Hunter — There are quite a few challenges to consider in this arena, maybe the toughest being the challenge of integrating networks which have overlapped Internet protocol (IP) address space. In order to maximize the efficiencies and economies of scale that are available with the integration of networks
