    QoS vs Traffic shaping, what is the difference?

    Well, I guess if you want to go by the formal definition of QoS... but I don't really consider it QoS unless you're dealing with more than one class of traffic. If you use OSPF only to form an adjacency between two IPs of a /30 either side of a point-to-point, is it really routing? Not the best...

    QoS vs Traffic shaping, what is the difference?

    Shaping is, as mentioned, a component of QoS, but it is ALSO something that can stand alone. Shaping is a way of buffering traffic temporarily and discarding packets when appropriate to prevent congestion or impose a limit upon the amount of bandwidth a connection uses. This is commonly used BY...

    Using public DNS for internal network?

    I don't know why everyone was suggesting running away from this company screaming. I love finding an IT flustercluck I can fix (I work for an ISP too) because after all the conference calls are done and the bosses are convinced and the necessary changes finally get made, I'm the hero. I can drop...

    Silent Push Out of Adobe Reader XI

    I used LANDesk for an over-11,000-CPU network and loved it. The asset-management portion most of all, though for software deployment it also worked well. Then again, I haven't really worked with many alternatives.

    Help plz, Linksys router causing internet speed to be cut in half (20mbps vs 50mbps)

    I've never even heard of that brand, so I'd probably avoid it. Processing power is what's important. You need to get a router which is actually rated for 50 Mbps on the WAN link. I've never seen a consumer wireless router that doesn't have at least a few switch ports in the back for wired...

    Ohhh I see. I've used the http get in an IP SLA before. Damn, I could have told you that at the beginning of this thread, except that I didn't really get what you were trying to accomplish. I've never worked with DDNS in IOS, to be honest.

    Boost internet speed? is this possible?

    It definitely sounds like they're using a WAN accelerator. It's really nothing special, though I'm sure they want you to think it is. WAN accelerators often employ TCP window size adjustments, ack delay changes, real-time compression, and local-caching options to reduce overhead, maximize...

    L2 between datacenters

    I would have suggested the tunnel if you don't want to pay for an MPLS (I'm another enterprise ISP WAN tech and it's pretty much our go-to solution for scenarios like these) but reading about OTV as Vito suggested above, it sounds pretty awesome.

    Packet Capture Analysis

    I can't say I know the best place to go, but in order to understand the Wireshark captures, you'll need to know how the TCP/IP stack and ethernet works, as well as any protocols involved with the services on your servers and network devices. Digging through my list of bookmarks, here's a few...

    Interesting. I've been doing a lot with IP SLA myself recently, but I've never considered it for running a script (though I'm guessing a track actually triggers the script?). Is this something you could share? It would be very useful to me.

    Boost internet speed? is this possible?

    Anyone who is telling you they can "optimize" TCP/IP to push more bandwidth than a circuit can handle is absolutely full of shit. TCP/IP are protocols that introduce overhead. IP is necessary for routing, TCP is necessary for ensuring data reliability. Both reduce your total data throughput...

    Transferring files wireless from one computer to another question

    Understand that approximately 50% of WiFi data is protocol overhead. Your actual data throughput will be, under best case circumstances, somewhat less than half of the connection speed you see on your laptop. (IE, a 300 Mbps connection will yield roughly 130 Mbps of actual data delivered). I'm...

    Why did my cable suddenly double in speed?

    Well as I pointed out earlier, my personal preference would be a Cisco I can micromanage with a relatively cheap WAP hanging off of it. In any case, there are circumstances where 5GHz wireless is well worth the expense, and I'm talking within the consumer / SOHO market.

    Internet connection disconnecting every time refrigerator starts/stops... Strange!

    If you're not using wireless (and if you are, moving from 2.4 GHz to 5 GHz wireless might fix the problem), then it's possible that a power sag when the condenser kicks in on your fridge is causing your NIC to lose its connection. If your router or modem are on the same circuit it'd be even more...

    Why did my cable suddenly double in speed?

    How much do you know about the 2.4 GHz band? There are only 3 channels that can be used simultaneously without overlapping on the band. Channels 1, 6, and 11. So if you see 30 APs, there are roughly 10(!) overlapping networks PER channel. Now WiFi uses CDMCA (Collision Avoidance) so it doesn't...

    Why did my cable suddenly double in speed?

    I like to carry my laptop, my smartphone, my tablet around within my home, and not have to deal with wireless interference making life difficult. Personally, I'd go with a cisco router since I work in dozens of them every day, and throw a cheap wireless N router off a switch port as a WAP.

    Home network security risk?

    Tell your son to hop on here, we'll straighten him out! Again though, from what I could see, Hamachi (or maybe just Windows Firewall) did block most ports. However, I'm not a hacker and I did cancel the penetration test so I didn't see what could have been exploited via the VPN tunnel. I told...

    Why did my cable suddenly double in speed?

    Gonna QTFT. The performance specs listed by cisco typically assume all services enabled. Otherwise they could end up selling you something that might not be able to handle the throughput with all the features you're running. Some other manufacturers take advantage of this (I've seen ADTRAN do...

    Home network security risk?

    Well that's really the point of a VPN; to allow a device to access your LAN via a WAN link. Your son is probably doing it so he can do some sort of gaming that typically requires the other player to have a PC present on the LAN. Unfortunately this works almost too well and does make the...

    Easier to do this than to try to explain to people all the time that bandwidth != throughput, that there's always protocol overhead involved.
