| Must packets always take the same up and downstream routes?
All I can think of is load balancing routes.. so no.
any other explanation?
THis is the last one for this time, lol
Thanks! | |

If you're thinking IP, then there's not even one up route, let alone the same up and down. Each packet is routed independently, that's the essence of packet switched networks. | |

| oh, yeah! I think too much and forgot the basics
I keep thinking how packets being routed to the destination. Then packets with same destination IP will be routed along the same route based on the routing table info...the only way is to have more than one routes to the same destination...
humm,seems contradicted ??? | |

Yeah, as long as the routing tables along the initial route don't change, which is very unlikely for sessions longer than, say, a few minutes. But the thing is, conditions in the network change constantly, and routers will update their routing tables, so your initial route will change. I would bet that when you browse www.examnotes.net/forums for an hour or so you're actually using tens of different routes. | |

| asynchronous routing can occur by bad design where the return path is not the same. This happens most often when exiting your "secure" network and either going to your DMZ or the internet, because internal routing tables are not shared with the DMZ/internet.
