Exam 14: The Internet Protocol

The counterpart of fragmentation is reassembly.

A device attached to one of the networks of an internet that is used to support end user applications or services is ________.

A device used to provide a communications path and perform the necessary relaying and routing functions so that data can be exchanged between devices attached to different networks in the internet is an ________.

A hop-by-hop option that is used to send IPv6 packets with payloads longer than 65,535 octets is ________.

Data are transmitted over an internet in packets from a source system to a destination across a path involving a single network and routers.

Priority could be assigned on a message basis or on a connection basis.

IP attaches a header to upper layer data to form an IP ________.

A protocol is concerned with exchanging data between two entities.

Although it is intended to ultimately be replaced,________ is currently the standard IP used in TCP/IP networks.

For virtually all protocols data are transferred in blocks called ________.

An entity may transmit data to another entity in such a way that each PDU is treated independently of all prior PDUs.This is known as ________ data transfer.

The principal feature of ________ is that it can encrypt and/or authenticate all traffic at the IP level.

The most widely used protocol for internetworking is the ________.

If dynamic or alternate routing is used the potential exists for a datagram to loop indefinitely through the internet.

Flow control allows routers and receiving stations to limit the rate at which they receive data.

A connectionless internet service is not good for connectionless transport protocols because it imposes unnecessary overhead.

The ________ is a means of uniquely identifying an end-system-originated datagram.

A ________ operates at layer 3 of the OSI architecture and routes packets between potentially different networks..

In IPv6 ________ may only be performed by source nodes,not by routers,along a packet's delivery path.

In the IPv4 Header ________ specifies how long,in seconds,a datagram is allowed to remain in the internet.
