The path between two end systems consists of two routers and three links. The link between the routers has a data rate of 100Mbps and the two access-links connecting the end systems to their corresponding routers have a data rate of 20Mbps. Assume all packets in the network are 10,000 bits (including headers). Compute the time it takes to send a packet from one system to the other under the following conditions: a. Propagation delays are negligible and all router queues are empty.
b. Propagation delays are negligible and a packet encounters: 2 packets ahead of it when it arrives to the first queue and 3 packets ahead of it when it arrives to the second . In this case assume that the first packet in the queue is about to start transmission.
c. All router queues are empty but propagation delays are not negligible. The three links have lengths 2000Km, 4000Km and 2000Km, respectively and the signal propagation speed is 200x10^6 m/sec.

okay, so i know we just goofed around in that chat, but ive been like genuinly depressed, like medically depressed for almost 4 years now. i had my first panic attack when i was 8. i woke my mum up and told her i felt like i was in a dream. like i was a goldfish in a bowl, looking at all these things going on around me and feeling . tiny. wort hless. and i now am now 17 y/o. i still feel those emotions daily. life used to go by so quick.like every day i would wake up and just like want to go back to bed cause i always felt like i was in the wrong place. i guess looking back, i was in the wrong state of mind. i took a expensive like nice trip to whyoming with my grandfather and ha ted it. like idk why. i would have loved it now, but i found myself writing in a journal everyday because i would forget what happened the day before, couldnt remember what i ate for like the previous meal. just my memory left me for the week i was there. worst feeling ive ever experienced.
