In the network, we usually use routers to allocate IP addresses. In the network protocol, the protocol that regulates the routing status is the routing selection protocol. Now let's take a look at the specific content of the routing protocol. First, let's take a look at its basic concepts and definitions. The routing selection protocol enables the router to dynamically broadcast and acquire paths and determine which paths are available for selection, and which one is the best path to transmit da

The network routing protocol is essential in the network. As a protocol for address management and allocation, there are many types of protocols. Next we will summarize several important routing protocols for you to explain. Generally, there are two typical routing Methods: Static Routing and dynamic routing ｡ Static Routing is a fixed route table set in a vro. Static Routing does not change unless the netw

Multicast routing is a good technology. It broadcasts data over the Internet. Unlike broadcast, due to broadcast storms, the router prohibits cross-route transmission of broadcast data. Multicast solves this problem. Currently, m$ software such as NetMeeting and WMS are widely used in multicast. Here we will discuss how to build your Linux into a multicast router.(Generally, gateways and routers do not support multicast data packets ). 1. Transmission Protocol Network Cameras provide many IP-b

Route information protocol (RIP) The routing information protocol was originally designed for Xerox PUPPARC universal protocol. In 1981, the Xerox network system protocol was collectively referred to as "GWINFO" and defined as RFC 1988 in 1058 ". The routing information protocol is easy to configure and works very well in small networks. However, in large networks, the routing information protocol is inefficient. As I said to myself, the routing information protocol will split your network. In a

similar to the concept of the network information table in Digital Video broadcast Digital Video Broadcasting, DVB. RSVP uses this request to access each node of the network through the network. On each node, RSVP tries to reserve resources for the stream. This makes it possible to provide images with quality of service and other real-time services. What is an IPv6 network protocol conversion mechanism? Why is a conversion mechanism required? IPv6 cannot replace IPv4 immediately. Therefore, IPv

Redundancy is common point for today's topologies. Especially in mission-critical networks The It is isn't acceptable that using only one gateway to reach a point. Because One gateway means single point of failure.With multiple gateways, you can still reach the remote node even if that's connect fails. As soon as one of the gateway down, the link changes through and other gateway. Here with the word gateway. I mean the router that router so you use to reach a point, or with redundancy, multiply

The previous article mentions the use of the Windows Store protocol, in fact the Windows Store protocol is only a protocol rule built into the system. We can also define a set of specifications of the Uri-scheme, in addition to other applications can be called, the application can also be called, to solve some special scenes, this talk about the specific discussion of this issue.For the resolution and use of the Windows Store protocol, you can read the previous article: http://www.cnblogs.com/zh

At present, dynamic routing protocols are widely used. So I have studied the comprehensive comparison between the two commonly used dynamic routing protocols. Here I will share with you, hoping to help you. The earlier IGRP protocol was invented by Cisco and is a dynamic routing protocol based on the distance vector algorithm. The Enhanced Interior Gateway Routing Protocol is an Enhanced version of the IGRP

Many of my friends are confused about the routing protocol. Here we will introduce all the routing protocols in detail. Let's take a look at the definition and classification of the routing protocol. A route consists of a static route table and a dynamic route table. The corresponding route table is called a static route table and a dynamic route table. The static route table is preset by the network administrator according to the network configuratio

network topology changes. Dynamic Routing is suitable for networks with large networks and complex network topologies. Of course, various dynamic routing protocols occupy network bandwidth and CPU resources to varying degrees. Static Routing and dynamic routing have their own characteristics and applicability. Therefore, dynamic routing is usually used as a supplement to Static Routing in the network. When a group is used to find the route in the vro

A network protocol is a collection of rules, standards, or conventions that are established for data exchange in a computer network. It specifies the format in which information must be used in communication and the meaning of these formats. Most networks have a layered architecture, each layered on top of it, providing some service to its upper layer, and masking the details of how to implement the service. The rule that the nth layer on one device communicates with the nth layer on another dev

A network protocol is a collection of standards, rules, and norms that a computer uses to Exchange data over a network. Common protocols are TCP protocol, IP Protocol, UDP protocol, ICMP protocol. These are all transport protocols, as well as application layer protocols such as HTTP protocol, FTP protocol, etc. This application layer protocol is meant to tell oth
