[Unit 8] Why do we regulate the sending rate to obtain a desirable bandwidth allocation?
The sending rate may be limited by two factors. The first is flow control, in the case that there is insufficient buffering at the receiver. The second is congestion, in the case that there is insufficient capacity in the network.
[Unit 8] Multiplexing can also be useful in the transport layer for another reason. Suppose, for example, that a host has multiple network paths that it can use. If a user needs more bandwidth or more reliability than one of the network paths can provide, a way out is to have a connection that distributes the traffic among multiple network paths on a round-robin basis. What is this modus operandi called?
Inverse multiplexing
[Unit 8] Write all elements of transport protocols.
Addressing
Connection establishment
Connection release
Error control and flow control
Multiplexing
Crash recovery
[Unit 8] What is NOT a primitive for transport services?
a. LISTEN
b. CONNECT
c. SEND
d. OPEN
open
[Unit 8] What is a unit of messages sent form transport entity to transport entity?
a. Data unit
b. Segment
c. Transport unit
d. Packet
segment
[Unit 8] Many of the server processes that can exist on a machine will be used only rarely. It is wasteful to have each of them active and listening to a stable Transport Service Access Points (TSAP) address all day long. What is an alternative scheme?
a. Listening Transport Protocol
b. Active Transport Protocol
c. Server Connection Protocol
d. Initial Connection Protocol
initial connection protocol
[Unit 8] What is a specific endpoint in the transport layer called?
a. Transport Protocol Point
b. Transport Service Access Point
c. Transport Endpoint
d. Transport Connection Point
transport service access point
[Unit 8] The problem of running out of IP addresses is not a theoretical one that might occur at some point in the distant future. It is happening right here and right now. The long-term solution is for the whole Internet to migrate to IPv6, which has 128-bit addresses. This transition is slowly occurring, but it will be years before the process is complete. To get by in the meantime, a quick fix was needed. The quick fix that is widely used today came in the form of ______________.
a. IP Extention
b. Address Extention
c. Network Address Translation
d. IP Translation
network address translation
[Unit 8] When an application (e.g., a user) process wishes to set up a connection to a remote application process, it must specify which one to connect to. The method normally used is to define transport addresses to which processes can listen for connection requests. In the Internet, these endpoints are called _______.
a. Internet Address
b. Ports
c. Points
d. Endpoints
ports
[Unit 8] An allocation is ____________ if the bandwidth given to one flow cannot be increased without decreasing the bandwidth given to another flow with an allocation that is no larger.
a. Allocation fair
b. Bandwidth fair
c. Max-min fair
d. Blance fair
max-min fair
