"historical issues ", it appeared in the early development history of computer networks and is rarely used now. Let's leave it to our friends who have an "archaeological" hobby to explore it. In. NET development, what we actually use is AddressFamily. InterNetwork and AddressFamily. InterNetworkV6, which represent IPv

What is the service instance The cloud server instance (ECS instance) is a virtual computing environment that contains the most basic computing components, such as CPU, memory, operating system, bandwidth, and disk. You can interpret an ECS instance as a stand-alone virtual machine. ECS instance is the core concept of

finds the ing between the computer name and IP address in its own database, it returns the IP address of the target computer to the WINS customer requesting the query. Another wins:Windows Internet Name Service (WINS)Wins provides a distributed database that registers and queries the ing between IP addresses and NetBIOS names in the routing network environment. This may be a suitable method for converting NetBIOS names and IP addresses, especially for complex

high, and the lack of uniform query syntax. Graph Database (graph) Neo4j, Infogrid, Infinite Graph Social networks, referral systems, and more. Focus on building a relationship map Graph structure Using graph structure correlation algorithm. such as shortest path addressing, N-degree relationship lookup, etc. Many times need to calculate the entire graph to get the information needed, and this structure

1. Cluster1.1 What is a clusterSimply put, a cluster (cluster) is a group of computers that provide users with a set of network resources as a whole. These individual computer systems are nodes of the cluster. An ideal cluster is that users never realize the underlying nodes of a clustered system, and in his/her view,

Would be seen as Martian source.If one of the machines on the network 192.168.0.x are plugged into the wrong switch and are effectively on the same network Segment (physical) as eth1, then you'll see Martian source from that IP address (or you had multiple networks that the Linux box is not aware of)Martian source is not a major thing, but such messages help mak

, improving network flexibility and availability. Server Load balancer has two meanings: first, a large amount of concurrent access or data traffic is distributed to multiple node devices for separate processing, reducing the user's waiting for response time. Second, computing of a single heavy load is distributed to multiple nodesPoint devices perform parallel processing. After each node device finishes pr

What is video-on-demand (VOD) technology VOD (Video on Demand) is the abbreviation of VOD technology, also known as interactive VOD system, meaning that according to the needs of users to play the corresponding video program, fundamentally changed the user in the past passive watch TV deficiencies.

Sock5 Proxy Server:The proxy and the proxy server communicate with each other through the "sock4/5 proxy protocol" (For details, refer to the RFC documentation ). The sock4 proxy protocol can be said to strengthen the HTTP Proxy protocol. It not only acts as a proxy for the HTTP protocol, but also acts as a proxy for all external connections, without protocol restrictions. That is to say, as long as you connect to the outside, it will give you a proxy

What is OSGi?OSGi is also known as the dynamic modular system of the Java language , which defines an infrastructure for the development of modular applications. OSGi containers already have several open source implementations, such as Knoflerfish,Equinox , and Apache Felix. Through these containers, you can split your application into multiple module units so th

In August 1991, a student from Finland posted the following paragraph in the Comp.os.minix News Group: Hello, all people using minix-I am doing a free operating system for 386 (486) at (just for hobbies, not as big and professional as GNU). This student is Linus Torvalds, and what he says ' hobby ' becomes Linux that we know today. Linux has caught the attention of hackers (hacker), which has joined Linux
