[WIP] Gota - a TCP Traffic Aggregator Written in Golang

Gota is a userspace multipath tcp solution.

Gota Active End(aka client) receives tcp traffic and forwards to Gota Passive End(aka server) use multipath tcp connections.

Usage Scenario

Sometimes, our network administrator enables rate-limiting for every tcp connection, the speed of our tcp connections can't reach the top. But if we create multi tcp connections, the traffic of all connections can be aggregated to reach the top speed.

Quick Start

We can use Gota as a library, or daemon.

Use Gota as Daemon

Fetch Gota binary

• Build from source

go get github.com/jim3ma/gota/gota

Or

• Download from Release page according to you os and architecture.

Update Server Configuration

PS: the config files already exist in examples folder, you can make a reference.

• Update and save as config.server.yml

# default for server, did not change it
mode: server

# log level: info debug warn error fatal panic
log: debug
verbose: true

# tunnel authenticate credential
auth:
  username: gota
  password: gota

# white list for remote ip
#whiteips:
#  - 127.0.0.1/32

# remote address with port for forwarding traffic
# suppose you want to speed up you 8080 port
remote: 127.0.0.1:8080

# PS: try to enable fast open and pool for speed up connection time

# fast open in server
fastopen: true

# connection pool in server
pool:
  enable: false
  count: 10
  # sometimes server will close some connections for long idle time,
  # set keepalive to refresh connections which idle for the special time.
  # unit: second
  # 0: do not refresh connections
  keepalive: 10

# tunnel listen address with port
tunnel:
  - listen: 127.0.0.1:12333
  - listen: 127.0.0.1:12336

• Launch Server

gota server --config config.server.yml

Update Client Configuration

• Update and save as config.client.yml

# default for server, did not change it
mode: client

# log level: info debug warn error fatal panic
log: debug
verbose: true

# tunnel authenticate credential
auth:
  username: gota
  password: gota

# local listen address with port
listen: 127.0.0.1:12363

# PS: try to enable fastopen and pool for speed up connection time

# fast open in server
fastopen: true

# Gota server addresses with port
tunnel:
  - remote: 127.0.0.1:12333 # connect server directly
  - remote: 127.0.0.1:12336
    # connect server using a proxy, currently Gota support http/https/socks5 proxy
    proxy: http://gota:gota@127.0.0.1:3128

• Launch Client

gota client --config config.client.yml

Try yourself

telnet 127.0.0.1:12363
# or
curl 127.0.0.1:12363

Use Gota as a library

TBD
