# Questions Week 11 Network Layer
## Aims
## Outcomes
1. Listing the 5 layers of the community mannequin.
i.
2. The community layer is comprised of two interacting layers, known as planes, what are these two planes?
i.
three. Briefly clarify the distinction between forwarding and routing in relation to the Network Layer.
i.
four. Give a quick rationalization: In classical or conventional routing, how is the management airplane logic decided?
i.
5. Give a quick rationalization: In SDN (Software program Outlined Networking) hos is the management airplane logic managed and distributed?
i.
6. In an IPv4 packet (see the IPv4) diagram posted within the Discord Channel (*notes-resources*), What’s the TTL fields function?
i.
7. What occurs to the worth of this subject every time it’s forwarded to a brand new router?
i.
eight. The Software layer packet known as a message. The Transport layer packer known as a section, what’s the Network layer packet known as?
i.
9. In a datagram, what’s the theoretical most of this measurement in IPv4 in line with the usual? What’s the useful most measurement because of the MTU?
i.
10. Fill within the clean. Each host on the web will need to have a ________ handle.
i.
11. True or False. Appropriate the sentence if false. You may have a subnet of 223.1.1.zero/24. The IP 223.1.1.100 is a legitimate handle on this subnet.
i.
12. True or False. Appropriate the sentence if false. You may have a subnet of 223.1.1.zero/24. The IP 223.1.2.100 is a legitimate handle on this subnet.
i.
13. Fill within the clean. There are three non-public networks outlined by RFC 1918 that routers won’t route by default. They’re 10.zero.zero.zero/eight, 172.16.zero.zero/16, and ______________ .
i.
14. Fill within the clean. One other title for a CIDR block is __________ (see RFC 950).
i.
15. On a neighborhood community, your house or on the college, what protocol do you utilize to acquire and IP handle?
i.
16. Utilizing that protocol within the earlier Question Assignment, what’s the title of the system that fingers out the IP handle?
i.
17. Briefly clarify what are the four steps between shopper and server to acquire an IP handle (RFC 2131 part three.1)?
i.
18. Briefly clarify the idea of NAT, what it does, and the place it’s used (RFC 2663).
i.
19. Briefly clarify the idea of a firewall, what it does and the place on the community it’s used.
i.
20. Taking a look at SDN match guidelines, from the category 11/03 recording Half I video — what are the three layers that an SDN controller can ahead based mostly on?
i.
21. Clarify in what means SDN routing violates classical layer three based mostly routing?
i.
22. Taking a look at RFC 1958, the unique architectural ideas of the web concerned transferring the connection intelligence to the “edges.” Taking a look at expertise like NAT, routing precedence queues, and SDN, the place will we see the community intelligence transferring?
i.
23. In coping with Routing Algorithm classes, the 2 basic ones are: per-router and logically centralized. Clarify the distinction between the 2 methodologies behind these algorithms.
i.
24. Fill within the clean: A set of routers underneath the management of 1 firm or group is known as ______________ system.
25. There are two major routing protocols, OSPF (RFC 2328) and BGP (RFC 4271).
i.
26. Which Routing Algorithm is used to propagate route updates between Autonomous Methods (AS)?
i.
27. Which Routing Algorithm is used to propagate route updates inside Autonomous Methods (AS)?
i.
28. True or False. Appropriate if False. The federal government distributes Autonomous Methods Numbers.
i.
