PrefaceHSF is a distributed remote service invocation framework, in fact, I prefer to remove the distributed word, because HSF itself is not a separate service (refers to a process), he is a component attached to your application, an RPC component (Remote procedure call--remote Procedure Call, a protocol that requests services from a remote computer program over a network without needing to know the underlying network technology. In the OSI network co

17: Detailed description of hsf-videostreamparser How can we make full use of live555 for real-time h264 RTP transmission?As you can see, in the existing hsf-videofileservermediasubsession, sink uses hsf-videortpsink and source uses hsf-videostreamframer. However, this connection is very complicated and many other node

HSF provides a distributed service development framework, Taobao internal use, and generally provides the functions and some implementation basis:1. Standard service-mode RPC1), service definition: OSGi-based service definition mode2), TCP/IP communication:Io mode: NIO, using Mina frameworkConnection mode: Long connectionServer-side connection pool with a limited sizeWebService Way3), serialization: Hessian serialization mechanism2.

RPC implementation principle (HSF, dubbo) from scratch (1), hsfdubbo Preface I have been away from the blog Park for a long time. Although I have read a lot of things I wrote before, I still feel that I should share some things that I think are useful with you. Now let's get started. After six years of work experience in some large companies, everyone who has been in large companies should know that they are constantly adding business and functions i

FFmpeg hsf-_slice_header_init Function Denial of Service Vulnerability (CVE-2015-8661)FFmpeg hsf-_slice_header_init Function Denial of Service Vulnerability (CVE-2015-8661) Release date:Updated on:Affected Systems: FFmpeg Description: CVE (CAN) ID: CVE-2015-8661FFmpeg is a free software that allows you to perform video, transfer, and stream functions in multiple formats of audio and video.In versions

I have been confused. I have always said that FFmpeg is very powerful, but I have never studied it. Today I finally learned about its strength! First of all, FFmpeg is successfully compiled and installed in Linux. For details about the installation process, refer to my previous blog! Here we will directly introduce how to pack .hsf-pure code streams into .mp4. Avi and other formats. I think there must be many netizens who are studying this issue and

Here, I will summarize my development experience and be familiar with kernel device nodes, which is helpful for Kernel-related driver learning and development. 1. View CPU Information On the android application settings page, you can view information about the mobile phone or tablet Android devices in the menu. This information is an interface reserved by the kernel. As a kernel developer, you can view this information directly in serial port debuggi

The program is written by PHP a websocket server, the client is connected to send messages continuously, the service side is responsible for responding to requests. Tested: Once per request of client, server PHP consumes time of Microsecs to MICROSECS (message size is different). The server is a single core, 30 clients, using top to view PHP processes occupy CPU around 3-5%, load average 1 minutes load display 0.05 or so. Basically meet expectations.

Assuming a slot has two cores, the motherboard is plugged into 2 slots, which is the 4-core system.(2) Core is what we usually call "nuclear", that is, dual-core, 4-core and so on.
