csc chp4 flashcards

topic = middleboxes

QuestionAnswer
what are middleboxes any intermediary box performing functions apart from normal, standard functions of an IP router on the data path between a source host and destination host
where do middleboxes apply NAT, application specific, firewalls/IDS, load balancers and cache
what initially happens with middleboxes proprietary (closed) hardware solutions
what do you have to do to move towards "whitebox" hardware implementing open API move away from proprietary hardware solutions / programmable local actions via match+action / move towards innovation/differentiation in software
what is the purpose of SDN logically centralized control and configuration management often in private/public cloud
what does NFV stand for network functions virtualization
what is NFV programmable services over whitebox networking, computation and storage
what protocols are in the IP hourglass physical, link, transport and application layers
what is the internet's "thin waist" one network layer protocol (IP)
how does the internet's "thin waist" implemented implemented by every internet-connected devices
what is the internet's middle age "love handles" middleboxes operating inside the network (NAT, caching, NFV, firewalls)
what is the principle of the architecture of the internet the goal is connectivity, the tool is the internet protocol and the intelligence is end to end rather than hidden in the network
what are three cornerstone beliefs simple connectivity / IP protocol = that narrow waist / intelligence, complexity at network edge
what is end-end argument some network functionality can be implemented in network or at network edge
diagram on end-end implementation of reliable data transfer slide 107
what's the 20th century phone net intelligence/computing at network switches
what is the internet pre-2005 intelligence, computing at edge
what is the internet post-2005 programmable network devices / intelligence, computing, massive application-level infrastructure at edge
how are forwarding tables (destination-based forwarding) or flow tables (generalized forwarding) computed by the control plane
what does MTU stand for max transfer size
what do network links have in IP fragmentation/reassembly largest possible link-level frame (different link types,; different MTUs)
what are some characteristics of large IP datagram divided within net one datagram becomes several datagrams / reassembled only at destination / IP header bits used to identify, order related fragments
IP fragmentation/reassembly example slide 113
DHCP: wireshark output (home LAN) example slide 114

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
