device discovery

ZZ from http://blog.csdn.net/fudan_abc/archive/2007/06/23/1662739.aspx By the way, record this blog: the Linux USB driver development of Mingyue may be available in the future. The three important concepts of the Linux device model are bus, device, and driver. that is, bus, device, driver. In fact, the kernel also defines such data structures. They are str

first, IntroductionService consumers need a robust service discovery mechanism that service consumers use to obtain network information from service Providers. Even if the service Provider's information changes, The service consumer does not need to modify the Configuration.The relationships between service providers, service consumers, and service discovery components are as Follows:1. at startup, each mic

Recently do experiments, found that Ryu topology discovery performance is not high, so read the Ryu Topology Discovery source code, consulted related papers, improved Ryu topology discovery performance, rewrite the code, and re-did the experiment, found that improved topology discovery module capabilities have been enh

This is a creation in Article, where the information may have evolved or changed. Section Seventh: Service Discovery and load balancing Original address Reprint please specify the original and translation address This article will focus on the important parts of the two microservices architectures: Service discovery and load balancing. And how they helped us 2017 years of constantly demanding horizontal exp

partition, and then the last step in the previous lesson is to say:In the last lesson, our final step is something like this:You can see that there are many devices. What/DEV/SDA, it contains the/dev/sda1,/dev/sda5,/dev/sda6 below.What is the meaning of these SDA?These are actually the names of the disk partitions under Linux. Dev is the first three letters of the English device that represents the equipment files. First letter: H or S. H re

Service Discovery with Apache Curator, discoverycurator Introduction to Curator Curator is a client tool for Zookeeper (people who do not know about Zookeeper can access ZooKeeper). It encapsulates connection processing between ZooKeeper client and zookeeper server and common operations on Zookeeper, provides abstract encapsulation of ZooKeeper application scenarios (recipe, such as the shared lock service and cluster leader election mechanism. Of cou

Zabbix's "template OS Linux" Templates support monitoring mounted disk space utilization, which is implemented using LLD (low-level discovery) without disk IO monitoring. This article describes the method of monitoring disk IO using the Zabbix LLD function.idea : First create discovery rules, configure the corresponding userparameter on the agent side, invoke the well-written shell script, dynamically find

CDP is short for Cisco Discovery Protocol, a data link layer Protocol. Through this Protocol, our network administrator can obtain information about devices that run the CDP Protocol adjacent to each other. CDP protocol version: CDP protocol is divided into two versions: CDPv1 and CDPv2. cisco router 12.0 (3) T or later IOS versions support CDPv2. CDPv1 is enabled by default in IOS 10.3 to 12.0 (3) T versions. When a cisco

Here we will analyze some specific content of the PPPoE protocol. We have also studied the PPP protocol before, so we can understand PPPoE more easily. This time we will also talk about the PPPoE discovery stage. Data packets of the PPPoE protocol are encapsulated in the data domain of the Ethernet frame. Ethernet frame headers include: 1. Target MAC address (the broadcast address in this phase is ffffffffffff) 2. source MAC address client MAC address

0. PrefaceThere are many different link resources in intelligent Optical network, such as fiber link, wavelength link, various STM link and VC layer link in SDH, and various OTM layer link and och layer link in otn, etc. These links are called Sub dot (SNP) links in Ason, for the scalability of routing protocols and routing diversity, several different SNP links can be combined into sub-dot pool (SNPP) links (These SNP links are called data links in Gmpls, and these SNPP links are called Busines

Vista provides a very considerate network function, one of which is called "discovery" by Microsoft and is often ignored. In fact, this function is very useful in the LAN of the Working group environment. It can be used to automatically discover each computer in the LAN. It also provides convenient functions such as Windows conference rooms, backups, and file transfers. The following is an example of a "discovery
