udp0

simple udp implementation

udp1

• packet loss tolerant udp connection with retry
• introduced a fault injection class
  • The fault injector is a server/client that passes messages back and forth between the existing client and gui, a man-in-the-middle.
  • The fault injector for the next stage introduces the fault that makes the previous stage unsuitable.
  • For instance, in packet loss we randomly don't forward packets.

udp2

• packet loss tolerant with retry
• corruption tolerant with TCP checksums
• expanded fault injection capability
  • we randomly scramble the bytes

udp3

• message ids for matching retries
• message id history for rejecting retries
• expanded fault injection capability
  • we late send packets by swapping a packet with its retry

TCP0

• ported UDP0 to use TCP and keep the same structure
• provides the same reliability as UDP3(mostly) with way less code

util

utilities and base structures for packing and transporting data

future folders

tcp0

• tcp0 buys reliability and smarter control logic
• multi-threaded connections for many clients
• more than one game instance
• leader boards

objectstreams0

• buys ability to transmit classes across a connection and intelligently use remote objects
• major cleanup from tcp0 object transmission

future tech

second game

• connect 4?

load balancers

• spread the request load to multiple server instances
• same service, many servers

proxies / gateways

• forward traffic through different routes
• provide services on many servers through unified gateway
• many servers, single server

directory server

• intelligent routing to different remote gateways

cdn(?)

• redirect traffic for static objects to more local servers
