Medius
Medius (SCE-RT) continued to get updated past the PS2 era, although its usage was more limited to certain studios, it didn't stop it from evolving. As such, a new subserver was introduced (MAPS), larger RSA Key sizes were used, MUIS had newer packet IDs, and a underlying plugins system was created for Zipper Interactive's branch of Medius.

Medius Components
Medius servers are split into 9 major components with MAPS being Zipper Interactive Only:
Medius Authentication Server (MAS)
First server the client generally hits.
Allows users to login, authenticate and obtain a session token to login to the Medius Lobby Server.
This server generally runs on port 10075.
Medius Universe Manager (MUM)
Keeps track of lobby rooms, game information, and players.
This server generally runs on port 10076.
Medius Lobby Server (MLS)
Handles license agreement, announcements, global chat room, clans, create games, and join games.
This server generally runs on port 10077 or sometimes 10078.
Medius Proxy Server (MPS)
Global chat room, clans, create games, and join games.
This server generally runs on port 10078.
Distributed Memory Engine Game Server (DME)
The DME Game Server is a "Reliable UDP" server that handles connections between clients on a game's current status.
Traditionally, the DME server runs on port 10073.
Medius Network Address Translation (NAT)
A UDP server used to give the client their IP Address.
Medius Universe Information Server (MUIS)
Server for providing the client with multiple other Medius stacks (MAS/MLS/MPS/DME).
This server generally runs on port 10071.
SCE-RT View Online (SVO)
Formerly known as: "Sports View Online", this server ran to send/receive stats of players to web sources, announcements served to the client, or for customary assets by game developers.
Generally runs on port 10060 over HTTP, and port 10061 over HTTPS.
Medius Profile Server (MAPS*)
Customized Medius Branch
Server acts as a "hybrid" between a MUIS*. Handles sending/receiving character list, and News/Eula to the client.
After successful handshake, asks for plugins.
Runs on TCP port 10073, and UDP port 10072 OR 10074.
Zipper Interactive games only.
Medius Additional Components
Medius File System
Used to handle incoming/outgoing files between servers.
Medius Plugins
Customized Medius Branch Used to extend the functionality of servers (DME, MAPS, MAS, MLS. MPS, MUM), allowing for more flexibility to tweak the game further than vanilla Medius titles.
Zipper Interactive games only.
Medius Protocol
This will be a detailed breakdown of each start of the server communication, and what each type is in each table, and for. Medius Messages will be broken down by each Request/Receive callback.
