配对插座 [英] Pairing sockets

问题描述

我有一个服务器程序（在所有三个主要的os系统上工作），在c ++中创建，努力连接两个陌生人通信。

I have a server program (works on all three major os systems), created in c++ which strives to connect two strangers for communication. My current model seems depreciated, and I am simply wondering if there is a better way to go about serving the clients.

- 服务器接收连接请求

- 禁止

-starts线程用于此套接字

-server receives connection request
-checks for ban
-starts thread for this socket

这些步骤]

与合作伙伴（支票经理）确认连接

- 未连接的请求合作伙伴来自经理类

- 接收在我的socket< - 客户端发送保持活动数据包每2s左右

- 断开通知管理器，并关闭线程。

-confirm connection with partner (check manager)
-if unconnected request partner from manager class
-receive on my socket <- client sends keep alive packets every 2s or so
-on disconnect inform manager, and close thread.

[管理员类的工作原理]

[the manager class works like this]

添加socket：push_back on我的sockPairs向量

- 请求合作伙伴：找到未连接的sockPair，如果没有创建新的sockPair，一旦连接，标记sockPair删除，如果已经标记，删除它。

-remove socket：将标记添加到我已断开连接的合作伙伴的经理ID

-check socket：检查管理器ID以断开连接

-add socket: push_back on my vector of sockPairs
-request partner: find unconnected sockPair, if none exist create new sockPair, once connected, mark sockPair for removal, if already marked, remove it.
-remove socket: add flag to manager id of partner that I've disconnected
-check socket: check manager id for disconnection

我想地图会更有效率，但我不积极，因为我从来没有与他们合作，你认为我应该改变什么？我希望能够用这个模型服务200个客户，我真的不确定当前模型是否可以处理它...

I'm thinking a map would be much more efficient, however I'm not positive, as I've never worked with them, what else do you think I should change? I'm hoping to be able to serve 200 clients with this model, I'm really unsure if the current model could handle it...

推荐答案

每个连接的线程只是不会缩放。你需要使用一个机制，如select（），poll（），epoll（），WSAAsyncSelect（）或任何其他的东西，让你查询一套套接字的事件。然后按顺序处理每个套接字，并重复。

A thread per connection simply does not scale. You need to use a mechanism such as select(), poll(), epoll(), WSAAsyncSelect() or anything else that will let you query a set of sockets for events. Then you process each socket in order, and repeat.
