Concept
Bufferbloat is a phenomenon where excessive buffering in a network causes high latency and jitter, degrading overall internet performance. It occurs when data packets are held in queues for too long, resulting in delayed transmission and poor user experience, particularly in real-time applications like video conferencing and online gaming.
Relevant Fields:
Concept
Network latency refers to the time it takes for data to travel from its source to its destination across a network, affecting the speed and performance of data transmission. It is influenced by factors such as propagation delay, transmission delay, processing delay, and queuing delay, and optimizing these can improve overall network efficiency.
Concept
Jitter refers to the variability in time delay in packet delivery over a network, which can severely impact the quality of real-time communications like VoIP and video conferencing. It is a critical factor in network performance and is often mitigated through techniques such as buffering and Quality of Service (QoS) settings.
Concept
Packet queuing involves the temporary storage of data packets in network routers or switches before they are forwarded to their destination. This process is crucial for managing network congestion, ensuring efficient data transmission, and maintaining quality of service (QoS).
Concept
Congestion control is a fundamental mechanism in network communication that ensures efficient data transfer by preventing network overload. It dynamically adjusts the rate of data transmission based on current network conditions to maintain optimal performance and prevent packet loss.
Concept
Quality of Service (QoS) refers to the performance level of a service, emphasizing the ability to provide predictable and reliable network performance by managing bandwidth, delay, jitter, and packet loss. It is crucial in ensuring optimal user experience, particularly in real-time applications like VoIP and streaming services.
Concept
Active Queue Management (AQM) is a network protocol technique used to manage congestion by proactively dropping packets before a queue becomes full, thus preventing packet loss and reducing delay. It aims to improve overall network performance and fairness among users by dynamically adjusting the queue length based on current network conditions.
Transmission Control Protocol (TCP) is a core protocol of the Internet Protocol Suite that enables reliable, ordered, and error-checked delivery of data between applications running on hosts communicating over an IP network. It ensures that data packets are delivered in the same order they are sent, providing a connection-oriented communication service that is essential for many internet applications like web browsing and email.
Concept
Round-trip time (RTT) is the duration it takes for a signal to travel from the source to a destination and back again, crucial for assessing network performance and latency. Understanding RTT is essential for optimizing data transmission efficiency, as it directly impacts the speed and reliability of communication networks.
Concept
The Bandwidth Delay Product (BDP) represents the maximum amount of data that can be in transit in a network at any given time, calculated as the product of the network's bandwidth and its round-trip delay time. It's crucial for optimizing network performance, as it helps in determining the optimal window size for data transmission to ensure efficient use of the network without causing congestion.
Concept
Flow control is a critical aspect of computer networking and programming that ensures data is transmitted efficiently and without overwhelming the receiving system. It balances the data flow between sender and receiver, preventing congestion and ensuring optimal performance of networks and applications.
Concept
Network congestion occurs when a network node or link is carrying more data than it can handle, leading to packet loss, delay, or blocking of new connections. Efficient congestion management is crucial to maintain optimal network performance and ensure data flows smoothly across the network infrastructure.
Concept
Queuing delay refers to the time a data packet spends waiting in a queue before it can be transmitted over a network. It is a critical factor in network performance, influenced by factors such as network congestion, queue management policies, and the arrival rate of packets.
