NanoMsg (NNG) & FlatBuffers the correct fit for this project?

由 社会主义新天地 提交于 2020-07-15 04:07:08
问题 Shout out if there is something better we should consider: I am looking for a very quick and simple way to get several programs (e.g. 5) - each running on separate nodes on a private OpenStack cloud to talk to each other. Packets will be short C++ structs (less than 100 bytes) Traffic will be light (probably less than 100/second) Latency is really not an issue. (what is a few ms between friends?) - we have lots of cycles and memory Messages should be done as pub/sub client/server paradigm

3 月，跳不动了？>>> 本文属于原创，转载注明出处，欢迎关注微信小程序 小白AI博客 微信公众号 小白AI 或者网站 https://xiaobaiai.net 或者我的CSDN http://blog.csdn.net/freeape [TOC] 首先说明的是本篇文章不从cmake的整个语法上去讲述，而是从一个实际项目的构建上入手，去了解如何优雅的去构建一个软件项目，搭建一个 C/C++ 软件项目基本的依赖组件，最后形成一个构建 C/C++ 软件项目的模板，方便后面新项目的重复使用。相信对我们日常的软件项目构建都会有很好的收获。废话不都说，开始。 1 我们需要知道的基础 首先熟悉cmake的一些基操，我们就可以信手捏来的、优雅去构建一个项目，避免踩到不必要的坑。涉及到的有： cmake的变量作用域？ cmake中的数据结构？ 宏函数与函数？ 如何去构建动静态库和找到这些库？ 如何去实现支持多平台的项目构建？ 如何去构建一个应用？ 如何实现项目的最后install？ 如何很友好的去展示构建过程的各种级别信息？ 如何适配cmake-gui，采用友好的ccmake或者cmake-gui实现构建？ 这里概括性说明下常用的cmake知识，总的来说cmake的作用就是让我们找到依赖的头文件和库文件，去编译源文件、链接目标文件(静态库也是目标文件的一个集合)，最后生成可执行文件或动/静态库：

Differences between ZeroMQ and WebSockets

由 江枫思渺然 提交于 2020-01-19 02:38:46
问题 I'd like to know what the differences are between the ZeroMQ and WebSockets protocols . I know WebSockets was designed for web browser clients, but I'm assuming it can also be used server to server. And, in that case, I'm wondering if it would be good to use WebSockets instead of something else like ZeroMQ for real-time messaging . Specifically, I'm worried about reliability and missing messages in case of temporary network failure. 回答1: A: Real-Time-Messaging is a nice tag, however You may

Nanomsg multicast bandwidth issue

由 泪湿孤枕 提交于 2020-01-16 09:08:16
问题 Can I have pure multicasting in pub/sub protocol of the nanomsg. As there can be N subscribers interested in a particular data for a single publisher, the same subscribed data is flowing in N different streams.If my bandwidth for a single stream is 10MB then the total bandwidth required for N streams is 10*N,thus there is a increase in the bandwidth .Can we reduce this bandwidth as we do in the multicasting?? Can anyone help me regarding this issue?? 回答1: As far as I understand the PUB/SUB

surveyor respondent pattern in nanomsg in python

由 廉价感情. 提交于 2020-01-16 00:46:17
问题 I am trying to write a surveyor respondent pattern. But it throws the error: nanomsg.NanoMsgAPIError: Operation cannot be performed in this state from nanomsg import * s1 = Socket(SURVEYOR) s1.bind('ipc://bob') s1.send(b'hello nanomsg') print(s1.recv()) s1.close() from nanomsg import * s2 = Socket(RESPONDENT) s2.connect('ipc://bob') print(s2.recv()) s2.send(b'Hello') s2.close() How can I implement this pattern in python? 回答1: Its a bug, it can be circumvented by inserting "time.sleep(0.1)",

问题 I've compiled the python wrapper of nanomsg and I want to create a python installer for the package. The package can be created by running python setup.py bdist --format=wininst However I would like nanomsg.dll/nanomsg.so to be included in the installer/package but I haven't found any documentation regarding this issue. 回答1: As stated in the documentation here one needs to add the following code to his setup.py script: setup( name='nanomsg', version=__version__, packages=[str('nanomsg'), str(
