CUBIC is a network congestion avoidance algorithm for TCP which can achieve high bandwidth connections over networks more quickly and reliably in the face of high latency than earlier algorithms. It helps optimize long fat networks. [1] [2] In 2006, the first CUBIC implementation was released in Linux kernel 2.6.13. [3]
A number of extensions have been made to TCP over the years to increase its performance over fast high-RTT links ("long fat networks" or LFNs). TCP timestamps (RFC 1323) play a double role: they avoid ambiguities due to the 32-bit sequence number field wrapping around, and they allow more precise RTT estimation in the presence of multiple ...
Agile-SD is a Linux-based CCA which is designed for the real Linux kernel. It is a receiver-side algorithm that employs a loss-based approach using a novel mechanism, called agility factor (AF). to increase the bandwidth utilization over high-speed and short-distance networks (low bandwidth-delay product networks) such as local area networks or ...
Applications that expect real-time responses and low latency can react poorly with Nagle's algorithm. Applications such as networked multiplayer video games or the movement of the mouse in a remotely controlled operating system, expect that actions are sent immediately, while the algorithm purposefully delays transmission, increasing bandwidth ...
RDMA over Converged Ethernet (RoCE) [1] is a network protocol which allows remote direct memory access (RDMA) over an Ethernet network. There are multiple RoCE versions. RoCE v1 is an Ethernet link layer protocol and hence allows communication between any two hosts in the same Ethernet broadcast domain.
Bufferbloat is the undesirable latency that comes from a router or other network equipment buffering too many data packets.Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput.
The worst-case latency requirement is defined as 2 ms for Class A and 50 ms for Class B, but has been shown to be unreliable. [5] [6] The per-port peer delay provided by gPTP and the network bridge residence delay are added to calculate the accumulated delays and ensure the latency requirement is met. Control traffic has the third-highest ...
Graphical depiction of contributions to network delay. Network delay is a design and performance characteristic of a telecommunications network.It specifies the latency for a bit of data to travel across the network from one communication endpoint to another.
