FAST-DISCOVERY-SERVER(1)

💅 NAME

fast-discovery-server — the centralized broker for DDS service discovery, and yes she's that girl 💖

✨ SYNOPSIS

fast-discovery-server -i ID [options]

🦋 DESCRIPTION

okay so bestie, picture this 🌸: eProsima Fast DDS is a Data Distribution Service (DDS) middleware implementation, and it's out here offering the feature of dynamically discovering communication entities inside a network. slay.

The DDS standard defines a Simple Discovery Protocol (SDP) to do that whole job, sharing the participants' info using well known multicast addresses and ports. and like, that's cute and all — out-of-the-box participant discovery, no setup, we love a low-effort queen 👑 — but she has a problem. it's giving scalability issues 💀 because the number of exchanged packets goes up exponentially as new participants get added to the system. exponential. in this economy?? no thank you.

and that's not even the worst part, because it also requires multicasting capabilities, which may not work reliably (think WiFi communication [1] — yeah, that case 🙈), or may not even be present at all. not me showing up to a multicast party that isn't happening 😭

so therefore, eProsima Fast DDS implements the Discovery Server (DS) protocol, which is a brand new discovery mechanism based on a centralized communications model. in this model, a core participant — referred to as a Server — handles all the information exchanged between participants on the network. one main character handling the group chat. iconic behavior, honestly 🫶

fast-discovery-server accepts the following arguments:

🎀 OPTIONS

• -i ID, --server-id ID — this one is mandatory, bestie, no skipping it 💅 she's the unique server identifier. specifies the zero based server position in the ROS_DISCOVERY_SERVER variable. zero based!! count from 0, not 1, don't embarrass me 🙈
• -l IP, --ip-address IP — the server interface on which to listen to the clients 👂 defaults to any, which is 0.0.0.0. she's open to everyone ✨
• -p PORT, --port PORT — the UDP port on which to listen to the clients 📮 defaults to 11811. memorize it, it's her number 🎀
• -b, --backup — creates a server with a backup file associated 💾 she keeps receipts, as she should 🧚
