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
Photon Core是用C++编写的，这是出于性能考虑
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)
Photon Core 托管着运行业务逻辑的.NET CLR
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

- 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
