  1. padme in rtoj on George Lucas May Be Completely Evil · · Score: 1

    the only purpose i can imagine for putting padme in rotj would be to include her in the "ghost revue" along with yoda, obiwan, and anakin. although i don't know how that would work as she's not a jedi.

    hehehehee...reminds me of something i did at my last job. i used to work at a very large financial company, the only access to the internet was http via a proxy server. i couldn't get access to my external email accounts. so i built an http tunnel to encapsulate ssh back to my box at home.

  9. free clue for cable companies on Comcast Gunning for NAT Users · · Score: 1

    you fools need to stop trying to ban selected user behavior and start putting some thought in bandwidth provisioning & quality of service mechanisms. your real goal is to keep your network from being saturated by a few users to the detriment to the rest.

    take a hint from the world of frame relay and implement a committed access rate/burst rate for your user connections, then provision your bandwidth around that.

    users x car = total bandwidth required

    to illustrate an example of this, i work for a major financial company, a slew of banks connect to us over a frame cloud. a T1 has 24 64k timeslots, we will place 48 customers on this at a 32k cir/ 64k burst rate. or 24 at 64/128. or 12 at 128/256. you get the idea.

    back to the cable co's : i recently priced DS3 45M internet access at 15k a month from the largest carrier in the us.

    45M = 1024k x 1024k x 45 = 47,185,920k

    47,185,920k / 512k cir = 92,160 subscribers max

    92,160 subscribers x 40$ monthly fee = 3,686,400$

    (i hope i didn't screw any of that math up, double check it)

    obviously there are other costs to consider aside from the cable companies internet connection, but still : how do they manage to make such a huge clusterfuck out of this?

  10. multihoming defined on Is the Internet Shutting Out Independent Players? · · Score: 5, Informative

    for those of you who are confused about the nature of multihoming :

    multihoming involves connecting to 2 or more isps and BGP publishing your ip space through both of them. this (ideally) involves having your own ARIN assigned ip space & AS number.

    the point of multihoming is to address redunancy for inbound as well as outbound connections. you can use 2 isps + nat + creative outbound routing to handle outbound traffic, but that does nothing for a potential web server you're trying give multiple inbound paths to.

  13. Re:Caching and port-scanning on Microsoft Worms and Global Routing Instability · · Score: 5, Interesting

    first off, i'd just like to say, i love it when a hardcore networking article gets posted to slashdot, the number of responses is so much lower due to the userbase having no experience with the subject; and mindless pontificating and chest beating (as in anti microsoft/pro linux articles) doesn't cut it with this subject matter.

    as an aside, i don't mean the above preamble as a negative statement about the specific poster i'm responding to.

    "Consequently, since routes time out after a while
    ...This would logically increase the load on route discovery protocols such as BGP."

    well...not exactly. when 2 routers are set up in BGP partnership they exchange an initial set of rotes which are statically set by the AS administrator, there's no dynamic discovery process. those routes are only changed under a few specific conditions : explicit changes announced by the BGP partner, or the loss of connectivity to the partner (too many missed hello packets). BGP route exchange is not based on some kind of dynamic route timeout/refresh algorithm as that would be horrifyingly inefficient.

    a few words on how routing and route caching work (this is assumed to be on an defaultless internet backbone router) :

    a packet enters the router destined for some ip address, a lookup against the routing table is done, the appropriate outbound interface is selected (this set is known as path determination), the packet is then sent to the appropriate outbound interface, re-framed, and sent out to the next hop (this step is known as switching); route caching associates a destination ip address with an next hop interface, thus bypassing the redundant route table lookup. a definate gain in efficiancy, cisco makes a number of advanced caching/switching engines that are used in thier high end core routers.

    to summarize/explain the BGP/worm paper : worms generate excessive traffic; the traffic overwhelms some routers and wan links; thus, BGP hello packets get lost or never sent depending upon traffic or router load; consequently the BGP routes are being announced/withdrawn at a high rate (this is known as route flapping). this is bad, having a route fail is not a problem, as long as it stays failed. rapidly changing states creates extra load on the router. route dampaning policies help, but with a worm creating these conditions everywhere at once the cumulative effect is instability.
