    An old favorite

    'Twas the night before start-up and all through the net, not a packet was moving; no bit nor octet. The engineers rattled their cards in despair, hoping a bad chip would blow with a flare. The salesmen were nestled all snug in their beds, while visions of data nets danced in their heads. And I with my datascope tracings and dumps prepared for some pretty bad bruises and lumps. When out in the hall there arose such a clatter, I sprang from my desk to see what was the matter.

    There stood at the threshold with PC in tow, An ARPANET hacker, all ready to go. I could see from the creases that covered his brow, he’d conquer the crisis confronting him now. More rapid than eagles, he checked each alarm and scrutinized each for its potential harm.

    On LAPB, on OSI, X.25! TCP, SNA, V.35!

    His eyes were afire with the strength of his gaze; no bug could hide long; not for hours or days. A wink of his eye and a twitch of his head, soon gave me to know I had little to dread. He spoke not a word, but went straight to his work, fixing a net that had gone plumb berserk; And laying a finger on one suspect line, he entered a patch and the net came up fine!

    The packets flowed neatly and protocols matched; the hosts interfaced and shift-registers latched. He tested the system from Gateway to PAD; not one bit was dropped; no checksum was bad. At last he was finished and wearily sighed and turned to explain why the system had died. I twisted my fingers and counted to ten; an off-by-one index had done it again…









  • What are the “actual speeds?” They’re selling 10gbps circuits so I don’t really see a problem with this.

    This article talks about low upload speeds on existing infra and completely ignores the fact that the limitations they spell out are a factor of extremely limited upload spectra on traditional DOCSIS networks. This is a problem with the technical standard, not the carriers (which have their own problems)

    The funniest part is that the DOCSIS4.0 spec is addressing this limitation yet here we are.

    Is node over subscription a problem? Absolutely. But I don’t think the root of that problem is the marketing department.

    I would not put much stock in this article because they are either uninformed on what they’re reporting on, or intentionally telling half truths. There are enough reasons to hate cable companies, we don’t need to invent new ones.
