Feature Overview 功能概述

     Photon is a real-time socket server and development framework that is fast, simple to use and flexible. Client SDKs are available for all major platforms:

     Photon是一个快速、简单、灵活、实时的Socket服务器和开发框架，客户端SDK可用于以下平台：

     The Photon high level architecture looks like this:

     Photon的高级架构体系：

     Basic Architecture 基本架构

• The Photon Core is written in native C++ for performance reasons
• • It uses IO Completions Ports (IOCP) for high performance socket handling
  • Implements the heavy “lifting” of the protocols (e.g. reliable UDP)
  • Support relaible UDP, TCP and Web Sockets

               它使用的是完成端口IOCP，用于高性能套接字的处理

               使用了更好的协议

               支持可靠的UDP，TCP和Web Sockets

• The Core hosts a .NET CLR which runs the business logic in C#
• • Contains the applications running on Photon
  • Written in C# (or any other .NET language)

               包括运行在Photon上所有的应用程序

               用C#编码

     Server Applications (C#) 服务器应用程序

• We provide several applications as starting point provided in source C# code
• • Lite: Simple and powerful room based game logic
  • LiteLobby: Lobby functionality and room logic
  • Policy: Policy server for Unity3d, Flash and Silverlight
  • LoadBalancing: Load balanced lite scaling across servers (this is powering our Photon Cloud)

          我们提供了多种应用作为开始点

               Lite：简单又强大的房间游戏逻辑基础

               LiteLobby：大厅功能和房间逻辑

               Policy：为U3D，Flash，Silverlight提供的策略服务

               LoadBalancing：负载均衡的Lite扩展服务器

• The apps are tuned for performance and can be used out of the box or extended

          这些应用是性能调优和可扩展的

• Convenient xcopy deploy (automatic or manual restart)

          方便部署（自动或手动重启）

     Protocols 协议层

• Photon Core supports the follwoing protocols
• • reliable UDP (based on eNET) and specially tuned for Client-2-Server architectures
  • Binary TCP
  • Web Sockets

          Photon Core支持以下协议

               可靠的UDP（基于eNet），专门针对Client-2-Server架构

               二进制TCP

               Web Sockets

• Transfer protocol is very lean and slim

          传输协议很精简

• Photon wraps up the networking layer of each client platform

          Photon包含了网络层的每个客户端平台

• Communicate cross-platform and cross-protocol

          通信是跨平台和跨协议的

• Put your data in hashtables and send it: forget about de-/serialization

          你的数据是放在hashtables中进行发送的，无需序列化和反序列化

     Server Dev Framework (C#) 服务器Dev框架

• All apps sit on top of a development framework that solves common tasks for you

          置于所有应用程序之下的一个开发框架，为你解决通用的任务

• Simple and flexible mapping of RPC calls to operation instances

          简单和灵活的映射调用RPC去操作实例

• Messages passing through fibers solve many threading problems

          信息传递是通过线程池来解决多线程的一些问题

• Designed to saturate bandwidth before the CPU becomes the bottleneck

          在CPU成为瓶颈之前设计成饱和带宽

     Server Development Tools 服务器开发工具

• Fully running in Visual Studio » F5 » Debug right from your code!

          完全运行在VS上，F5可以进行调试

• Use all the first class tools from .NET Development
• • Microsoft: Visual Studio
  • Redgate: Memory Profiler, Performance Profiler, Reflector (see here )
  • Jetbrains: ReSharper, dotTrace, dotCover, dotPeek (see here )

          可使用的工具

     Data Persistence (DBs) 数据持久层

• Photon does not provide an persistence layer

          Photon不提供数据持久层

• .NET/Windows supports all major products
• • SQL: MySQL, Postgres, MS SQL Server, SQLLite, …
  • NoSQL: MongoDB , Redis , MemCached , …

          .NET/Windows提供SQL和NoSQL

• Usage of ORM (mapping) layers optional

          可使用ORM（对象关系映射）

     Vast Support of Client Platforms 支持的客户端平台
