SOE(Simple Object Exchange)

作为(中小型)服务者和消息者模式的另一种选择:provider<-->router<-->consumer
优点:
1 一定的分布式处理能力,同一类型的proivder可以开多个,router自动均衡请求到provider。
2 router置于公网,provider和consumer可以在不同网络(即使一个国外,一个国内)!
3 服务调用不需要暴露IP和端口,只需要知道应用名字即可。
4 降低成本
弱点:
1 效率不如直接来得快,中间多了一层router,如果都在内网影响不是很大。
2 存在一个中心(router)。TODO 后期计划提供主备切换功能。
注:大量消息或大文件不建议直接使用。使用前请合理评估。

soe-client:相对于router的客户端,

其可以扮演两种角色分别是Provider(服务提供者)和Consumer(服务消费者)。
Consumer调用Provider的服务中间是通过了Router的。
SoeClient是Consumer或者还是Provider取决于业务是否对外提供服务接口

soe-router:消息交换器。

为什么不直接就是提供者和消费者,而中间有这个存在?
这个是SOE区别于其它provider<-->consumer,SOE的特点.
SOE 只是为了多一种选择,使用provider<-->consumer + VPN也可以实现在不同网络中服务。

soe-console:控制台

包括应用注册中心,应用统计,黑名单管理等。需要手动部署到tomcat

soe-demo: soe-router,soe-client 示例

isocket-aio:一个基于Java AIO的框架,可单独使用。思路借鉴Smart-Socket。

使用都只需要自己实现一个或者多个Protocol(即实现多层协议)和Processor接口就可以。
普通用户只需要关注,如果去实现Protocol中传输对象的编码(encode)和解码(decode)以及 Processor中的业务处理(process)方法即可。

isocket-nio:基于Java NIO实现,与isocket-aio用法一样,兼容一些不支持Java AIO的平台。

sokect : thread 为 n:m ,且 n>=m

isocket-aio-demo: isocket-aio 示例

SOE PROTOCOL

_Length|FromId(2)|FromSn(1)|ToId(2)|ToSn(1)|ServiceId(2)|Type(1)|MessageId(4)|Body(n)|_Limiter
说明:
_Length,FixLengthBigBufferProtocol 协议头
FromId,2个字节short类型,来源AppId
FromSn,1个字节byte类型,来源序号,一个ID启动多份时序列号SN不一样。
ToId,2个字节short类型,目的AppId
ToSn,1个字节byte类型,目的序号,一个ID启动多份时序列号SN不一样。不指定ToSn或者ToSn=0时,随机发送到ToId应用
ServiceId,2字节short类型,目标应用中已注册的服务ID
Type,1字节byte类型,告诉SoeClient消息的类型 
MessageId,4字节int类型,一定时间内,标识一条消息的唯一性,特别是阻塞等待消息返回的情况下。
Body,变长N
_Limiter,FixLengthBigBufferProtocol 协议尾
