Quick Answer: Why Is TCP Traffic Elastic Traffic?

What is elastic traffic?

1.4 Elastic traffic Elastic traffic has the ability of making adjustment of wide-ranging changes in delay and throughput across the internet and still meets the needs of the applications.

It adjusts its throughput between end hosts in response to network condition.

Network load or congestion may cause packet loss..

What uses UDP protocol?

UDP is commonly used for applications that are “lossy” (can handle some packet loss), such as streaming audio and video. It is also used for query-response applications, such as DNS queries.

What is congestion control techniques?

Closed loop congestion control technique is used to treat or alleviate congestion after it happens. Several techniques are used by different protocols; some of them are: Backpressure : Backpressure is a technique in which a congested node stop receiving packet from upstream node.

What is it goal of congestion control?

Definition: Congestion control is a method used for monitoring the process of regulating the total amount of data entering the network so as to keep traffic levels at an acceptable value. This is done in order to avoid the telecommunication network reaching what is termed w:congestive collapse.

What is difference between flow control and congestion?

The main difference between flow control and congestion control is that, In flow control, Traffics are controlled which are flow from sender to a receiver. On the other hand, In congestion control, Traffics are controlled entering to the network. … In this, Network is prevented from congestion.

Is UDP still used?

UDP is a connection-less protocol and is used in protocols like SNMP and DNS in which data packets arriving out of order is acceptable and immediate transmission of the data packet matters.

Does Netflix use UDP?

Netflix, Hulu, Youtube, etc. video streaming all use TCP and simply buffer a few seconds of content, instead of using UDP since the delay is not crucial and TCP transfers can be easily accomplished over HTTP and web browsers without the need for additional plugins and software.

What is the main advantage of UDP?

What is the main advantage of UDP? Explanation: As UDP does not provide assurance of delivery of packet, reliability and other services, the overhead taken to provide these services is reduced in UDP’s operation. Thus, UDP provides low overhead, and higher speed.

What is an elastic application?

We use terms like “TCP Friendly” to describe the Internet’s “elastic” applications. We mean “when it encounters delay, loss, or bandwidth limitations, the application (via TCP/SCTP) adapts its rate to maximize throughput”

How is TCP congestion control done?

TCP uses a congestion window in the sender side to do congestion avoidance. The congestion window indicates the maximum amount of data that can be sent out on a connection without being acknowledged. TCP detects congestion when it fails to receive an acknowledgement for a packet within the estimated timeout.

What is difference between scalability and elasticity?

Scalability is the ability of the system to accommodate larger loads just by adding resources either making hardware stronger (scale up) or adding additional nodes (scale out). Elasticity is the ability to fit the resources needed to cope with loads dynamically usually in relation to scale out.

What is elastic architecture?

An Elastic Cloud Enterprise installation consists of a number of core services. This service-oriented architecture lets you: Scale the platform easily. Different services can have different reliability and performance requirements, as each service can be scaled separately.

What does elastic mean in AWS?

ability to acquire resourcesThe ability to acquire resources as you need them and release resources when you no longer need them. In the cloud, you want to do this automatically.
