HLT

Hidden Lake Traffic

The Hidden Lake Traffic is an application that saves traffic passed through HLS. The saved traffic can be used by other applications when they were offline. HLT provides an API for loading and unloading messages. Messages are stored in the inmemory database based on the "ring" structure. Thus, new messages will overwrite the old ones after some time. Can act as a TURN server for HLS's or other P2P nodes with GP/12 protocol.

Installation

$ go install github.com/number571/hidden-lake/cmd/hlt@latest

How it works

HLT emulates HLS to receive messages. In this scenario, HLT has only the functions of accepting messages, without the ability to generate or send them via HLS or independently.

Figure 1. Example of running HLT client.

Supported platforms

• Windows (x86_64, arm64)
• Linux (x86_64, arm64)
• MacOS (x86_64, arm64)

Minimum system requirements

1. Processor: 1x2.2GHz (characteristic for relayer mode)
2. Memory: 0.5GB RAM (~200MB of memory is consumed in relayer mode)
3. Storage: 20Gib available space (the size of messages per day from one node in storage mode)

Build and run

Default build and run

$ go run ./cmd/hlt

> [INFO] 2023/06/03 15:39:13 HLT is running...
> ...

Open ports 9581, 9582 (TCP, HTTP). Creates ./hlt.yml, ./hlt.db files. The file hlm.db stores all sent/received messages as structure ring from network HL.

Default config hlt.yml

settings:
  message_size_bytes: 8192
logging:
  - info
  - warn

Running options

$ hlt -path=/root -network=xxx
# path    = path to config and database files
# network = use network configuration from networks.yml

Example

Build and run service

$ cd examples/traffic_actions/keeper
$ make

Run client
