429 Too Many Requests (RFC 6585) The user has sent too many requests in a given amount of time. Intended for use with rate-limiting schemes. [24] 431 Request Header Fields Too Large (RFC 6585) The server is unwilling to process the request because either an individual header field, or all the header fields collectively, are too large. [24]
The given precondition has not been met. [9] 413 Request Entity Too Large Request body too large. [1]: §21.4.11 414 Request-URI Too Long The server is refusing to service the request because the Request-URI is longer than the server is willing to interpret. [1]: §21.4.12 415 Unsupported Media Type Request body in a format not supported.
Low-density parity-check (LDPC) codes are a class of highly efficient linear block codes made from many single parity check (SPC) codes. They can provide performance very close to the channel capacity (the theoretical maximum) using an iterated soft-decision decoding approach, at linear time complexity in terms of their block length.
Network congestion in data networking and queueing theory is the reduced quality of service that occurs when a network node or link is carrying more data than it can handle. . Typical effects include queueing delay, packet loss or the blocking of new connectio

The channel efficiency, also known as bandwidth utilization efficiency, is the percentage of the net bit rate (in bit/s) of a digital communication channel that goes to the actually achieved throughput. For example, if the throughput is 70 Mbit/s in a 100 Mbit/s Ethernet connection, the channel efficiency is 70%.
Help message. Explains how to use the server or the meaning of a particular non-standard command. This reply is useful only to the human user. 215: NAME system type. Where NAME is an official system name from the registry kept by IANA. 220: Service ready for new user. 221: Service closing control connection. Logged out if appropriate. 225
In computing, load balancing is the process of distributing a set of tasks over a set of resources (computing units), with the aim of making their overall processing more efficient. Load balancing can optimize response time and avoid unevenly overloading some compute nodes while other compute nodes are left idle.
