In [[computer networking]], '''linear network coding''' is a program in which intermediate nodes transmit data from source nodes to sink nodes by means of [[linear combination]]s.

Linear network coding may be used to improve a network's throughput, efficiency, and [[scalability]], as well as reducing attacks and eavesdropping. The [[Node (networking)|node]]s of a network take ''several'' packets and combine for transmission. This process may be used to attain the maximum possible [[information]] [[flow network|flow]] in a [[Network theory|network]].

It has been proven that, theoretically, [[linear code|linear coding]] is enough to achieve the upper bound in multicast problems with one source.<ref>S. Li, R. Yeung, and N.

Linear network coding is still a relatively new subject. However, the topic has been vastly researched over the last twenty years. Nevertheless, there are still some misconceptions that are no longer valid:

'''Decoding computational complexity:''' Network coding decoders have been improved over the years. Nowadays, the algorithms are highly efficient and parallelizable. In 2016, inwith Intel Core i5 processors with [[Single instruction, multiple data|SIMD]] instructions enabled, the decoding goodput of network coding was 750 MB/s for a generation size of 16 packets and 250 MB/s for a generation size of 64 packets.<ref>{{Cite book |last1=Sørensen |first1=Chres W. |last2=Paramanathan |first2=Achuthan |last3=Cabrera |first3=Juan A. |last4=Pedersen |first4=Morten V. |last5=Lucani |first5=Daniel E. |last6=Fitzek |first6=Frank H.P. |title=2016 IEEE Wireless Communications and Networking Conference |chapter=Leaner and meaner: Network coding in SIMD enabled commercial devices |date=April 2016 |chapter-url=https://www.researchgate.net/publication/314198052 |pages=1–6 |doi=10.1109/WCNC.2016.7565066|isbn=978-1-4673-9814-5 |s2cid=10468008 |archive-url=https://web.archive.org/web/20220408093330/https://www.researchgate.net/profile/Chres-Sorensen/publication/314198052_Leaner_and_Meaner_Network_Coding_in_SIMD_Enabled_Commercial_Devices/links/5a008b894585159634bafaa8/Leaner-and-Meaner-Network-Coding-in-SIMD-Enabled-Commercial-Devices.pdf |archive-date=2022-04-08 }}</ref> Furthermore, today's algorithms can be vastly parallelizable, increasing the encoding and decoding goodput even further.<ref>{{Cite journal |last1=Wunderlich |first1=Simon |last2=Cabrera |first2=Juan A. |last3=Fitzek |first3=Frank H.

'''Transmission Overhead:''' It is usually thought that the transmission overhead of network coding is high due to the need to append the coding coefficients to each coded packet. In reality, this overhead is negligible in most applications. The overhead due to coding coefficients can be computed as follows. Each packet has appended <math>M</math> coding coefficients. The size of each coefficient is the number of bits needed to represent one element of the Galois field. In practice, most network coding applications use a generation size of no more than 32 packets per generation and Galois fields of 256 elements (binary-8). With these numbers, each packet needs <math>M * log_2(s) = 32</math> bytes of appended overhead. If each packet is 1500 bytes long (i.e. the Ethernet MTU), then 32 bytes represent an overhead of only 2%.

[[File:LinDependenciesbinary.png|thumb|448x448px|Expected linearly dependent packets at different stages of transmission for a Galois field <math>GF(2)</math> and a generation size of 16 packets. At the beginning of the transmission, the linear dependencies are minimal. It is the last packet of the transmission that is more likely to be linearly dependent.]]

[[File:LinDependenciesbinaryvsg.png|thumb|445x445px|The expected number of linearly dependent packets per generation is practically independent of the generation size.]]

'''Overhead due to linear dependencies:''' Since the coding coefficients are chosen randomly in RLNC, there is a chance that some transmitted coded packets are not beneficial to the destination because they are formed using a linearly dependent combination of packets. However, this overhead is negligible in most applications. The linear dependencies depend on the Galois fields' size and are practically independent of the generation size used. We can illustrate this with the following example. Let us assume we are using a Galois field of <math>q</math> elements and a generation size of <math>M</math> packets. If the destination has not received any coded packet, we say it has <math>M</math> degrees of freedom, and then almost any coded packet will be useful and innovative. In fact, only the zero-packet (only zeroes in the coding coefficients) will be non-innovative. The probability of generating the zero-packet is equal to the probability of each of the <math>M</math> coding coefficient to be equal to the zero-element of the Galois field. I.e., the probability of a non-innovative packet is of <math>\frac{1}{q^M}</math>. With each successive innovative transmission, it can be shown that the exponent of the probability of a non innovative packet is reduced by one. When the destination has received <math>M-1</math> innovative packets (i.e., it needs only one more packet to fully decode the data). Then the probability of a non innovative packet is of <math>\frac{1}{q}</math>. We can use this knowledge to calculate the expected number of linearly dependent packets per generation. In the worst-case scenario, when the Galois field used contains only two elements (<math>q=2</math>), the expected number of linearly dependent packets per generation is of 1.6 extra packets. If our generation size if of 32 or 64 packets, this represents an overhead of 5% or 2.5%, respectively. If we use the binary-8 field (<math>q=256</math>), then the expected number of linearly dependent packets per generation is practically zero. Since it is the last packets the major contributor to the overhead due to linear dependencies, there are RLNC-based protocols such as tunable sparse network coding<ref>{{Cite book |last1=Feizi |first1=Soheil |last2=Lucani |first2=Daniel E. |last3=Sørensen |first3=Chres W. |last4=Makhdoumi |first4=Ali |last5=Médard |first5=Muriel |title=2014 International Symposium on Network Coding (NetCod) |chapter=Tunable sparse network coding for multicast networks |date=June 2014 |chapter-url=https://ieeexplore.ieee.org/document/6892129 |pages=1–6 |doi=10.1109/NETCOD.2014.6892129|isbn=978-1-4799-6217-4 |s2cid=18256950 }}</ref> that exploit this knowledge. These protocols introduce sparsity (zero-elements) in the coding coefficients at the beginning of the transmission to reduce the decoding complexity, and reduce the sparsity at the end of the transmission to reduce the overhead due to linear dependencies.
