TCP流转换为KCP+UDP流，:zap:***[下载地址](https://github.com/xtaci/kcptun/releases/latest)***:zap:工作示意图：

> *Disclaimer: kcptun maintains a single website — [github.com/xtaci/kcptun](https://github.com/xtaci/kcptun). Any websites other than [github.com/xtaci/kcptun](https://github.com/xtaci/kcptun) are not endorsed by xtaci.*
|
||||
|
||||
|
||||
### QuickStart
|
||||
|
||||
Increase the number of open files on your server, as:
|
||||
|
||||
`ulimit -n 65535`, or write it in `~/.bashrc`.
|
||||
|
||||
Suggested `sysctl.conf` parameters for better handling of UDP packets:
|
||||
***kcptun是[kcp](https://github.com/xtaci/kcp-go)协议的一个简单应用，可以用于任意tcp网络程序的传输承载，以提高在丢包环境下的网络流畅度。***
|
||||
_采用极简设计，客户端＋服务器源码总共400行，方便用户自己扩展_ 。
|
||||
|
||||
### *快速设定* :lollipop:
|
||||
```
|
||||
net.core.rmem_max=26214400 // BDP - bandwidth delay product
|
||||
net.core.rmem_default=26214400
|
||||
net.core.wmem_max=26214400
|
||||
net.core.wmem_default=26214400
|
||||
net.core.netdev_max_backlog=2048 // proportional to -rcvwnd
|
||||
服务器: ./server_linux_amd64 -t "127.0.0.1:1080" -l ":554" -mode fast2 // 转发到本地1080端口
|
||||
客户端: ./client_darwin_amd64 -r "IP地址:554" -l ":1080" -mode fast2 // 监听本地1080端口
|
||||
```
|
||||
|
||||
You can also increase the per-socket buffer by adding parameter(default 4MB):
|
||||
### *使用の方法* :lollipop:
|
||||
|
||||
|
||||
|
||||
### *适用范围限定* :lollipop:
|
||||
1. 实时网络游戏的数据传输
|
||||
2. 跨运营商的流量传输
|
||||
3. 其他高丢包通信链路的TCP承载
|
||||
|
||||
### *推荐参数* :lollipop:
|
||||
```
|
||||
-sockbuf 16777217
|
||||
适用大部分ADSL接入（非对称上下行）的参数（实验环境电信100M ADSL）
|
||||
SERVER: -mtu 1400 -sndwnd 2048 -rcvwnd 2048 -mode fast2
|
||||
CLIENT: -mtu 1400 -sndwnd 256 -rcvwnd 2048 -mode fast2 -dscp 46
|
||||
其它带宽请按比例降低窗口，比如50M ADSL，把CLIENT的 -sndwnd -rcvwnd减掉一半,SERVER不变
|
||||
```
|
||||
for **slow processors**, increasing this buffer is **CRITICAL** to receive packets properly.
|
||||
*巭孬嫑乱动*
|
||||
|
||||
Download a corresponding one from precompiled [Releases](https://github.com/xtaci/kcptun/releases).
|
||||
### *DSCP* :lollipop:
|
||||
DSCP差分服务代码点（Differentiated Services Code Point），IETF于1998年12月发布了Diff-Serv（Differentiated Service）的QoS分类标准。它在每个数据包IP头部的服务类别TOS标识字节中，利用已使用的6比特和未使用的2比特，通过编码值来区分优先级。
|
||||
常用DSCP值可以参考[Wikipedia DSCP](https://en.wikipedia.org/wiki/Differentiated_services#Commonly_used_DSCP_values)，至于有没有用，完全取决于数据包经过的设备。
|
||||
|
||||
### *内置模式* :lollipop:
|
||||
响应速度:
|
||||
*fast3 >* ***[fast2]*** *> fast > normal > default*
|
||||
有效载荷比:
|
||||
*default > normal > fast >* ***[fast2]*** *> fast3*
|
||||
中间mode参数比较均衡，总之就是越快越浪费带宽，推荐模式 ***fast2***
|
||||
更高级的 ***手动档*** 需要理解KCP协议，并通过 ***隐藏参数*** 调整，例如:
|
||||
```
|
||||
KCP Client: ./client_darwin_amd64 -r "KCP_SERVER_IP:4000" -l ":8388" -mode fast3 -nocomp -autoexpire 900 -sockbuf 16777217 -dscp 46
|
||||
KCP Server: ./server_linux_amd64 -t "TARGET_IP:8388" -l ":4000" -mode fast3 -nocomp -sockbuf 16777217 -dscp 46
|
||||
```
|
||||
The above commands will establish port forwarding channel for 8388/tcp as:
|
||||
|
||||
> Application -> **KCP Client(8388/tcp) -> KCP Server(4000/udp)** -> Target Server(8388/tcp)
|
||||
|
||||
which tunnels the original connection:
|
||||
|
||||
> Application -> Target Server(8388/tcp)
|
||||
|
||||
### Install from source
|
||||
|
||||
```
|
||||
$go get -u github.com/xtaci/kcptun/...
|
||||
-mode manual -nodelay 1 -resend 2 -nc 1 -interval 20
|
||||
```
|
||||
|
||||
All precompiled releases are genereated from `build-release.sh` script.
|
||||
### *前向纠错* :lollipop:
|
||||
前向纠错采用Reed Solomon纠删码, 它的基本原理如下： 给定n个数据块d1, d2,…, dn，n和一个正整数m， RS根据n个数据块生成m个校验块， c1, c2,…, cm。 对于任意的n和m， 从n个原始数据块和m 个校验块中任取n块就能解码出原始数据， 即RS最多容忍m个数据块或者校验块同时丢失。
|
||||
|
||||
### Performance

### Basic Tuning Guide
|
||||
|
||||
#### Improving Thoughput
|
||||
|
||||
> **Q: I have a high speed network link, how to reach the maximum bandwidth?**
|
||||
|
||||
> **A:** Increase `-rcvwnd` on KCP Client and `-sndwnd` on KCP Server **simultaneously & gradually**, the mininum one decides the maximum transfer rate of the link, as `wnd * mtu / rtt`; Then try downloading something and to see if it meets your requirements.
|
||||
(mtu is adjustable by `-mtu`)
|
||||
|
||||
#### Improving Latency
|
||||
|
||||
> **Q: I'm using kcptun for game, I don't want any lag happening.**
|
||||
|
||||
> **A:** Lag means packet loss for most of the time, lags can be improved by changing `-mode`.
|
||||
|
||||
> eg: `-mode fast3`
|
||||
|
||||
> Aggresiveness/Responsiveness on retransmission for embeded modes are:
|
||||
|
||||
> *fast3 > fast2 > fast > normal > default*
|
||||
|
||||
#### HOLB
|
||||
|
||||
Since streams are multiplexed into a single physical channel, head of line blocking may appear under certain circumstances, by
|
||||
increasing `-smuxbuf` to a larger value (default 4MB) may mitigate this problem, obviously this will costs more memory.
|
||||
|
||||
#### Slow Devices
|
||||
|
||||
kcptun made use of **ReedSolomon-Codes** to recover lost packets, which requires massive amount of computation, a low-end ARM device cannot satisfy kcptun well. To unleash the full potential of kcptun, a multi-core x86 homeserver CPU like AMD Opteron is recommended.
|
||||
If you insist on running under some ARM routers, you'd better turn off `FEC` and use `salsa20` as the encryption method.

#### Forward Error Correction
|
||||
|
||||
In coding theory, the [Reed–Solomon code](https://en.wikipedia.org/wiki/Reed%E2%80%93Solomon_error_correction) belongs to the class of non-binary cyclic error-correcting codes. The Reed–Solomon code is based on univariate polynomials over finite fields.
|
||||
|
||||
It is able to detect and correct multiple symbol errors. By adding t check symbols to the data, a Reed–Solomon code can detect any combination of up to t erroneous symbols, or correct up to ⌊t/2⌋ symbols. As an erasure code, it can correct up to t known erasures, or it can detect and correct combinations of errors and erasures. Furthermore, Reed–Solomon codes are suitable as multiple-burst bit-error correcting codes, since a sequence of b + 1 consecutive bit errors can affect at most two symbols of size b. The choice of t is up to the designer of the code, and may be selected within wide limits.
|
||||
|
||||
|
||||
|
||||
Setting parameters of RS-Code with ```-datashard m -parityshard n``` on **BOTH** KCP Client & KCP Server **MUST** be **IDENTICAL**.
|
||||
|
||||
#### DSCP
|
||||
|
||||
Differentiated services or DiffServ is a computer networking architecture that specifies a simple, scalable and coarse-grained mechanism for classifying and managing network traffic and providing quality of service (QoS) on modern IP networks. DiffServ can, for example, be used to provide low-latency to critical network traffic such as voice or streaming media while providing simple best-effort service to non-critical services such as web traffic or file transfers.
|
||||
|
||||
DiffServ uses a 6-bit differentiated services code point (DSCP) in the 8-bit differentiated services field (DS field) in the IP header for packet classification purposes. The DS field and ECN field replace the outdated IPv4 TOS field.
|
||||
|
||||
setting each side with ```-dscp value```, Here are some [Commonly used DSCP values](https://en.wikipedia.org/wiki/Differentiated_services#Commonly_used_DSCP_values).
|
||||
|
||||
#### Cryptanalysis
|
||||
|
||||
kcptun is shipped with builtin packet encryption powered by various block encryption algorithms and works in [Cipher Feedback Mode](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Cipher_Feedback_(CFB)), for each packet to be sent, the encryption process will start from encrypting a [nonce](https://en.wikipedia.org/wiki/Cryptographic_nonce) from the [system entropy](https://en.wikipedia.org/wiki//dev/random), so encryption to same plaintexts never leads to a same ciphertexts thereafter.
|
||||
|
||||
The contents of the packets are completely anonymous with encryption, including the headers(FEC,KCP), checksums and contents. Note that, no matter which encryption method you choose on you upper layer, if you disable encryption by specifying `-crypt none` to kcptun, the transmit will be insecure somehow, since the header is ***PLAINTEXT*** to everyone it would be susceptible to header tampering, such as jamming the *sliding window size*, *round-trip time*, *FEC property* and *checksums*. ```aes-128``` is suggested for minimal encryption since modern CPUs are shipped with [AES-NI](https://en.wikipedia.org/wiki/AES_instruction_set) instructions and performs even better than `salsa20`(check the table below).
|
||||
|
||||
Other possible attacks to kcptun includes: a) [traffic analysis](https://en.wikipedia.org/wiki/Traffic_analysis), dataflow on specific websites may have pattern while interchanging data, but this type of eavesdropping has been mitigated by adapting [smux](https://github.com/xtaci/smux) to mix data streams so as to introduce noises, perfect solution to this has not appeared yet, theroretically by shuffling/mixing messages on larger scale network may mitigate this problem. b) [replay attack](https://en.wikipedia.org/wiki/Replay_attack), since the asymmetrical encryption has not been introduced into kcptun for some reason, capturing the packets and replay them on a different machine is possible, (notice: hijacking the session and decrypting the contents is still *impossible*), so upper layers should contain a asymmetrical encryption system to guarantee the authenticity of each message(to process message exactly once), such as HTTPS/OpenSSL/LibreSSL, only by signing the requests with private keys can eliminate this type of attack.
|
||||
|
||||
Important:
|
||||
1. `-crypt` and `-key` must be the same on both KCP Client & KCP Server.
|
||||
2. `-crypt xor` is also insecure and vulnerable to [known-plaintext attack](https://en.wikipedia.org/wiki/Known-plaintext_attack), do not use this unless you know what you are doing. (*cryptanalysis note: any type of [counter mode](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Counter_(CTR)) is insecure in packet encryption due to the shorten of counter period and leads to iv/nonce collision*)

|
||||
|
||||
The encrytion performance in kcptun is as fast as in openssl library(if not faster).
|
||||
|
||||
|
||||
#### Memory Control
|
||||
|
||||
Routers, mobile devices are susceptible to memory consumption; by setting GOGC environment(eg: GOGC=20) will make the garbage collector to recycle faster.
|
||||
Reference: https://blog.golang.org/go15gc
|
||||
|
||||
Primary memory allocation are done from a global buffer pool *xmit.Buf*, in kcp-go, when we need to allocate some bytes, we can get from that pool, and a *fixed-capacity* 1500 bytes(mtuLimit) will be returned, the *rx queue*, *tx queue* and *fec queue* all receive bytes from there, and they will return the bytes to the pool after using to prevent *unnecessary zer0ing* of bytes.
|
||||
The pool mechanism maintained a *high watermark* for slice objects, these *in-flight* objects from the pool will survive from the perodical garbage collection, meanwhile the pool kept the ability to return the memory to runtime if in idle, `-sndwnd`,`-rcvwnd`,`-ds`, `-ps`, these parameters affect this *high watermark*, the larger the value, the bigger the memory consumption will be.
|
||||
|
||||
`-smuxbuf` also affects the maximum memory consumption, this parameter maintains a subtle balance between *concurrency* and *resource*, you can increase this value(default 4MB) to boost concurrency if you have many clients to serve and you get a powerful server at the same time, and also you can decrease this value to serve only 1 or 2 clients and hope this program can run under some embeded SoC system with limited memory and only you can access. (Notice that the `-smuxbuf` value is not proprotional to concurrency, you need to test.)
|
||||
|
||||
|
||||
#### Compression
|
||||
|
||||
kcptun has builtin snappy algorithms for compressing streams:
|
||||
|
||||
> Snappy is a compression/decompression library. It does not aim for maximum
|
||||
> compression, or compatibility with any other compression library; instead,
|
||||
> it aims for very high speeds and reasonable compression. For instance,
|
||||
> compared to the fastest mode of zlib, Snappy is an order of magnitude faster
|
||||
> for most inputs, but the resulting compressed files are anywhere from 20% to
|
||||
> 100% bigger.
|
||||
|
||||
> Reference: http://google.github.io/snappy/
|
||||
|
||||
Compression may save bandwidth for **PLAINTEXT** data, it's quite useful for specific scenarios as cross-datacenter replications, by compressing the redologs in dbms or kafka-like message queues and then transfer the data streams across the continent can be much faster.
|
||||
|
||||
Compression is enabled by default, you can disable it by setting ```-nocomp``` on **BOTH** KCP Client & KCP Server **MUST** be **IDENTICAL**.
|
||||
|
||||
#### SNMP
|
||||
通过```-datashard 10 -parityshard 3``` 可以调整Reed Solomon参数。
|

Sending a `SIGUSR1` signal to KCP Client or KCP Server will dump SNMP information to console, just like `/proc/net/snmp`. You can use this information to do fine-grained tuning.
|
||||
使用```kill -SIGUSR1 pid``` 可以在控制台打印出SNMP信息，通常用于精细调整***当前链路的有效载荷比***。
|
||||
观察```RetransSegs,FastRetransSegs,LostSegs,OutSegs```这几者的数值比例，用于参考调整```-mode manual,fec```的参数。
