What is datagram Subnet?
datagram subnet is connection oriented network.
What is the role of the address field in a packet travelling through a datagram?
There are two address fields. Source is the IP address the packet came from and destination is the IP address the packet is meant to be delivered to.
Which operation is used by a router to extract the destination network address from the destination IP address of a packet?
Route table lookup
What can be identified by the network layer header?
destination host address
What happens when a node on an Ethernet network is creating a frame and it does not have the destination MAC address?
The node sends out an ARP request with the destination IP address.
Which portion of a received datagram is decoded and used by the internetwork layer of the tcpip model?
Only the Network Layer (Layer 3) portion of the datagram is used by the Network Layer (Layer 3) portion of the TCP/IP Model. The network portion of the datagram includes IP Addressing information, and things such as TTL (Time to Live), and Datagram Priority markings.
What information is found in the network layer header?
The destination host address
Is the default gateway address a portion of the destination IP address?
No, it is not. A destination IP address may be any address, usually on a completely different network. The default gateway address is used to determine where to send packets that need to be routed outside of the current local area network.
What are the two most important network layer functions in a datagram network?
Forwarding and Routing.
Which network components are identified by a Backbone Destination Address and a Backbone Source Address?
The Provider Edge Bridges
What can be identified by examining network layer encapsulation?
IP source and destination address
What is the effect of a router on delimiting broadcast traffic and conserving bandwidth?
Generally speaking, routers will unicast-forward incoming packets which have a network broadcast address as destination, unless they are directly connected to that network/subnet and therefore know that the destination address is a broadcast address
