Question

我已经读到很多东西,一是关于接受边测量(RSS)、接受包装指导(RPS)和类似技术,但我却对我如何实际使用我的方案中的那些技术,即不同校对/处理之间的隔.。

我确实知道PF_RING,但我相信,在林丹本身必须有某种基础支持。毕竟,Interl(例如)在其网站上刊登了有关其RSS技术的机器,并主张对LC提供支持。而且,皇家警察部队不属于人民论坛的范围。另一个原因是,Im不愿意使用PF_。令人不安的是,他们派遣了网络司机,其中一些派遣的司机似乎已经过时。

我广泛概括了这个专题,但我所发现的最佳途径是使科索沃警察部队或皇家警察部队能够提供支持,而不是我如何从方案上加以利用。

Kernel 3.19 注有了这一过程,便可以发现邮联最初交付了包装。

替代RPS/RFS的办法是使用硬件支持多端。

Then split a set of million of sockets into worker threads, each one using epoll() to manage events on its own socket pool.

Ideally, we want one thread per RX/TX queue/cpu, but we have no way to know after accept() or connect() on which queue/cpu a socket is managed.

We normally use one cpu per RX queue (IRQ smp_affinity being properly set), so remembering on socket structure which cpu delivered last packet is enough to solve the problem.

After accept(), connect(), or even file descriptor passing around processes, applications can use :

in;

获取(fd, SOL_SOCKET,SO_INCOMING_CPU, &cpu, &len);

And use this information to put the socket into the right silo for optimal performance, as all networking stack should run on the appropriate cpu, without need to send IPI (RPS/RFS).
