Week 8 UAS

Question 1

What is Routing?

Answer 1

• Routing is the process of deciding what path to take from sender to receiver (packet forwarding).
• usually there is more than one route possible; devices that perform routing must keep tables to make decisions about which path to send packets.
• Handled by Routers that maintain their own routing tables
• Routing tables indicates next route to which datagram should be sent

Question 2

What is DHCP?

Answer 2

The Dynamic Host Configuration Protocol (DHCP) is a standardized network protocol used on Internet Protocol (IP) networks for dynamically distributing network configuration parameters, such as IP addresses for interfaces and services.

Question 3

Types of Routing?

Answer 3

1. Centralized routing
   Routing decisions are made by one central computer.
   Centralized routing can be found on small, mainframe-based networks.
2. Distributed (decentralized routing)
   Routing decisions are made independently at each
   routing node, although routers do exchange information).
   Two types:
   – Static routing
   – Dynamic routing

Question 4

Routing Strategies?

Answer 4

1. Fixed
2. Flooding
3. Random
4. Adaptive

Question 5

Layer 3 switch terdapat 2 kategori yaitu?

Answer 5

• Packet by Packet

* Flow-based switch

Question 6

RIP and OSPF?

Answer 6

RIP and OSPF are popular intradomain or intra-AS routing protocols (also called interior routing protocols) used to update routing tables in an AS.

RIP is based on distance vector routing, in which each router shares, at regular intervals, its knowledge about the entire AS with its neighbors.

OSPF divides an AS into areas, defined as collections of networks, hosts, and routers. OSPF is based on link state routing, in which each router sends the state of its neighborhood to every other router in the area.
