ZeroC ICE之旅------负载均衡及容错
Zero ICE我们已经掌握其基本运行原理。下面我们主要介绍一下ICe的多端口邦定的问题。ICE使用TCP/IP 和UDP协议，以及基于TCP/IP之上的SSL协议。SSL协议可以充分保障Server/Client数据传输的加密安全性问题。在这里，Server如何在同一台主机监听多个端口。关于TCP/IP还是UDP还是SSL协议的选择，还是要看具有应用的要求，通常情况下TCP/...2008-04-21 17:13:29 · 888 阅读 · 0 评论 -
ZeroC ICE之旅------Slice
Slice是在ICE所特有的特殊语言，ICE 提供基于Ice语言的多语言映射工具。Slice主要针对程序所涉及到的接口和类型进行定义。不涉及到具体实现和具体语言的特征。 既然ICE支持跨语言的调用，那么是不是Slice支持每种的特有数据类型呢？ 当然不是，ICE只是保留各种具体语言数据类型的最小交集。提供：[code="java"]1.bool (false or...2008-04-18 13:10:35 · 214 阅读 · 0 评论 -

ICE之轻量级分布式通讯中间件
Ice 是 Internet Communications Engine 的简称，出自ZeroC名门之下。Ice 是一种面向对象的中间件平台。从根本上说，这意味着Ice 为构建面向对象的客户－服务器应用提供了工具、API 和库支持。Ice 应用适合于异构平台环境中使用：客户和服务器可以采用不同的编程语言，可以运行在不同的操作系统和机器架构上，并且可以使用多种网络技术进行通信。无论部署环境如何，...2008-04-15 16:32:23 · 565 阅读 · 0 评论 -

关于<Nginx and Memcached, a 400% boost!>
