I'd also argue that any DHCP server that applies that policy of artificially limiting the IP pool by re-issuing non-expired leases is an asinine implementation.
Of course people are going to like devices that allow them to cut in line if there is a little bit of space.
Something tells me Saurik is a tad more invested at this point, it's not really as simple as "avoiding Apple devices" when you are the dev of Cydia.
How many people do you think would install that patch?
* Resolves potential IP conflicts when recovering from sleep
* Adds 10s to network availability in most situations
> They want the device to work when they turn it on.
No, it just potentially kicks off another user. I've never been unable to acquire an IP because of this practice, I've just seen other people's wireless mysteriously give up the ghost when I connect with my iPhone or Mac. I would prefer to have the aggressive device, personally.
* If you have a valid lease, there should be no conflicting IP addresses on the network
* Even if you do have a conflicting IP address, that conflict only exists until the DHCP server issues you a new one (iOS immediately performs the DHCP request after sniffing)
IP conflicts are not voodoo magic. Once the conflicting machine gets a new IP address, everything returns to normal. The network events shown in the article show that this occurs in about 1s; between the time that the interface comes up, 0.3s, and the time the interface is active, 1.3s. If this were a full negotiation, it would take around 5s.
The key thing to remember is that this shouldn't happen at all on healthy networks. So, if anyone chooses to remain opposed to this, they're saying that waiting 10s every time you wake a portable device from sleep and want to use the network connection is a worthwhile tradeoff to accommodate DHCP servers that don't respect leases and switches that can't adequately resolve an ARP entry conflict in a timely manner.
I've said it about ten times in this discussion already, but I'll keep the ten seconds (times 15-20 sleep/wake events per day) and buy decent network equipment.
So, by basic game theory, everyone implements 'asshole mode' in their devices. What happens on a technical level when every device behaves like that?
We start putting battery backup in routers so they won't drop their DHCP tables? This isn't asshole mode, it's "assume the network is functioning properly and hasn't been reset" mode. In the world of portable devices, it's important to look at where we waste time and compensating for errors is a frequent culprit.
