# UDPspeeder
|
||
Network Speed-Up Tool. Boost your Connection on a High Lantency High Packet-Loss Link by using Forward Error Correction.
|
||
|
||
When used alone,UDPspeeder speeds-up only udp connection.Nevertheless,if you used UDPspeeder + any UDP based VPN together,you can speed-up any traffic(include tcp/udp/icmp)。
|
||
|
||
|
||
|
||
[简体中文](/doc/README.md)
|
||
|
||
# Efficacy
|
||
tested on a link with 100ms latency and 10% packet loss at both direction
|
||
|
||
### Ping Packet Loss
|
||
|
||
|
||
### SCP Copy Speed
|
||
|
||
|
||
# Supported Platforms
|
||
Linux host (including desktop Linux,Android phone/tablet,OpenWRT router,or Raspberry PI).
|
||
|
||
For Windows and MacOS You can run UDPspeeder inside [this](https://github.com/wangyu-/udp2raw-tunnel/releases/download/20170918.0/lede-17.01.2-x86_virtual_machine_image_with_udp2raw_pre_installed.zip) 7.5mb virtual machine image.
|
||
|
||
# How does it work
|
||
|
||
UDPspeeder uses FEC(Forward Error Correction) to improve your connection's quality,at the cost of addtional bandwidth.The algorithm for FEC is Reed-Solomon.
|
||
|
||
# Getting Started
|
||
|
||
### Installing
|
||
Download binary release from https://github.com/wangyu-/UDPspeeder/releases
|
||
|
||
### Running
|
||
Assume your server ip is 44.55.66.77, you have a service listening on udp port 7777.
|
||
|
||
```bash
|
||
# Run at server side:
|
||
./speederv2 -s -l0.0.0.0:4096 -r 127.0.0.1:7777 -f20:10
|
||
|
||
# Run at client side
|
||
./speederv2 -c -l0.0.0.0:3333 -r44.55.66.77:4096 -f20:10
|
||
```
|
||
|
||
Now connecting to UDP port 3333 at the client side is equivalent to connecting to port 7777 at the server side,and the connection is boosted by UDPspeeder.
|
||
|
||
Note：-f20:10 means sending 10 redundant packets for every 20 original packets.

||
### Usage
|
||
```
|
||
UDPspeeder V2
|
||
git version:f479ca2779 build date:Oct 19 2017 01:37:08
|
||
repository: https://github.com/wangyu-/UDPspeeder
|
||
|
||
usage:
|
||
run as client : ./this_program -c -l local_listen_ip:local_port -r server_ip:server_port [options]
|
||
run as server : ./this_program -s -l server_listen_ip:server_port -r remote_ip:remote_port [options]
|
||
|
||
common option,must be same on both sides:
|
||
-k,--key <string> key for simple xor encryption. if not set,xor is disabled
|
||
main options:
|
||
-f,--fec x:y forward error correction,send y redundant packets for every x packets
|
||
--timeout <number> how long could a packet be held in queue before doing fec,unit: ms
|
||
--mode <number> fec-mode,available values: 0,1 ; 0 cost less bandwidth,1 cost less latency
|
||
--report <number> turn on send/recv report,and set a period for reporting,unit:s
|
||
advanced options:
|
||
--mtu <number> mtu. for mode 0,the program will split packet to segment smaller than mtu_value.
|
||
for mode 1,no packet will be split,the program just check if the mtu is exceed.
|
||
default value:1250
|
||
-j,--jitter <number> simulated jitter.randomly delay first packet for 0~<number> ms,default value:0.
|
||
do not use if you dont know what it means.
|
||
-i,--interval <number> scatter each fec group to a interval of <number> ms,to protect burst packet loss.
|
||
default value:0.do not use if you dont know what it means.
|
||
--random-drop <number> simulate packet loss ,unit:0.01%. default value: 0
|
||
--disable-obscure <number> disable obscure,to save a bit bandwidth and cpu
|
||
developer options:
|
||
-j ,--jitter jmin:jmax similiar to -j above,but create jitter randomly between jmin and jmax
|
||
-i,--interval imin:imax similiar to -i above,but scatter randomly between imin and imax
|
||
-q,--queue-len <number> max fec queue len,only for mode 0
|
||
--decode-buf <number> size of buffer of fec decoder,unit:packet,default:2000
|
||
--fix-latency <number> try to stabilize latency,only for mode 0
|
||
--delay-capacity <number> max number of delayed packets
|
||
--disable-fec <number> completely disable fec,turn the program into a normal udp tunnel
|
||
--sock-buf <number> buf size for socket,>=10 and <=10240,unit:kbyte,default:1024
|
||
log and help options:
|
||
--log-level <number> 0:never 1:fatal 2:error 3:warn
|
||
4:info (default) 5:debug 6:trace
|
||
--log-position enable file name,function name,line number in log
|
||
--disable-color disable log color
|
||
-h,--help print this help message
|
||
```
