NeL Network Library : Features
+ + +

Introduction

+

The first objective of NeL's network library (NeL Net) is to provide a complete OS-independent data transfer API that abstracts system specific code and provides mechanisms for complete control of bandwidth usage by the application code.

+

NeL Net has a further objective of providing a complete toolkit, comprising further layers of library code and core service implementations, for the development of performance critical distributed program systems for massively multi user universe servers.

+ +

Features

+

General Features

+
    +
  • A layer based architecture with API access to every layer +
  • Client application API +
  • Encapsulation of process of connection to Shard Front End +
  • Encapsulation of buffering and data transmission to Shard Front End +
  • Encapsulation of reception and decoding of messages within data packets received from shard +
  • Current implementation is based on TCP/IP +
+ +

Shard Back End application ('service') Framework and API

+
    +
  • Framework for developing new services +
  • Abstraction of inter-service connections with disconnection and reconnection management +
  • Management of transmission of messages to other services (with buffering) +
  • Management of reception and treatment of messages from other services (with buffering) +
  • Management of time synchronisation +
  • Management of log messages with consolidation and filtering tools +
  • Centralised shard administration and management +
  • Current implementation is based on TCP/IP +
+ +

Shard Front End application API

+
    +
  • All features pertaining to back end services +
  • Multi-threaded client-communication management for large numbers of client connections +
  • Separation of incoming messages from the shard back end and incoming messages from clients +
  • Login authentication +
  • Mechanisms for monitoring growth of output data packets to the application program +
  • Current implementation is based on TCP/IP +
+ +

Login/ logout management

+
    +
  • Automated system fo registration of shards with Login Manager +
  • API for connection of client application to Login Manager, for login and password authentication and for valid shard list retrieval by the client. +
  • API for selection of a shard (for an authenticated user), selection of least loaded front end server on the shard for client connection and secure system for establishing the client connection. +
+ + +

On the fly backup management (to be developped)

+
    +
  • Management of a backup schedules and shard backup synchronisation +
  • Standalone service dedicated to reception and secure storage of backup data (with concept of transactions and data coherency) +
  • Service API for backing up data +
+ +

Future Spec enhancements (to be developped)

+
    +
  • Multi-threaded application support +
  • Add a UDP channel from Client to Shard front end +
  • Investigate ways of adding a UDP channel from shard to client (looks tricky) +
  • Add support for data compression +
  • Optimisation of communication between services running on the same server (via pipes and/ or shared memory) +
