a static route table. Generally, it is set in advance according to the network configuration during system installation, it will not change as the network structure changes in the future. Dynamic) the route table is the route table automatically adjusted by the Router Protocol according to the running status of the network system. The router selects the Routing Protocol) to automatically learn and remember the network running status, and automaticall

other sensor nodes, and the energy supply module supplies energy for the operation of the entire sensor network. The energy supply of sensor nodes is battery, and the node energy is limited. Consider extending the life cycle of the entire sensor network as much as possible. When designing sensor nodes, ensuring the continuity of energy supply is an important design principle. Sensor node energy consumption modules mainly include sensor modules, information processing modules, and wireless commu

1 Some problems of restricting BGP expansibility BGP is the IP network Interconnection protocol applied to Internet, which provides a stable and secure routing protocol for the interconnection between operators, and has rich routing control mechanism. To better control the routing strategy, most operators now deploy BGP to backbone routers. With the continuous e

Static Routing has the following purposes:In a small network with no significant growth, it is easy to maintain the route table using static routes.Static Routing can be routed to the remote network or from the remote network to the external network (see Chapter 2nd ).Use a single default route. If a network cannot find a more matched route entry in the route table, you can use the default route as the path

layers to complete their own functions. Both parties can communicate with each other only at the same level. Common protocols include TCP/IP, IPX/SPX, and NetBEUI. IPX/SPX is usually used in the LAN .. If you access the Internet, you must add the TCP/IP protocol to the network protocol. Let's briefly introduce the differences between different transmission protocols: IPX/SPXInternet group Exchange/ordered

NetBEUI protocol was proposed by IBM in 1985. NetBEUI is mainly designed For a LAN of 20 to 200 workstations. It is used For NetBEUI, LanMan, Windows For WorkgroUPS, and Windows NT networks. NetBEUI is a compact and fast Protocol. However, because NetBEUI does not have the routing capability, it cannot route from one LAN to another, and can no longer adapt to a large network. To route to another Lan, you must install TCP/IP or IPX/SPX. IPX/SPX (Inter

Redis Research (13)-security and communication protocols, redis research communication protocols I. Security Salvatore Sanfilippo, author of Redis, once published the Redis declaration, which mentions Redis to be concise and beautiful. Redis does not do much work at the security level.1. trusted environmentThe Redis security design is based on the premise that "Redis runs in a trusted environment". During t

Open source is already widely used in today's software industry, but does open source mean that users can do whatever they want to do with open source code? The answer is no. Open-source sports also have their own game rules and ethics. Failing to comply with these rules will not only damage the healthy development of the open source movement, but also cause reputational and market losses to violators, and more likely fall into legal disputes and compensation. There are many open-source

The usage of softswitch protocol is described in four special protocols. Next we will give a brief introduction to several main Softswitch protocols, such as H.248/MEGACO, Media Gateway Control Protocol MGCP), and Session Initiation Protocol SIP. Main protocols used by Softswitch The softswitch system involves many Softswitch

A Preliminary Study on WCF-17: the equivalence of WCF data protocols, a preliminary study on wcf-17 protocolsData contract equivalenceFeatures If the client successfully sends data of a certain type to the service or the service successfully sends the data to the client, the receiving end does not necessarily have to send data of this type. The only requirement is that the two types of data protocols sho

OC-Concepts and usage of protocols, oc-concepts of protocols In the previous article, we introduced the class extension in OC: Extend. The protocol in OC is equivalent to the interface (abstract class) in Java, but the name in OC is more vivid, because when we are learning interfaces in Java, it can be seen that the interface is equivalent to a contract (Protocol), marking its implementation class. Of cour

Escape characters in communication protocols and escape characters in communication protocolsEscape characters in communication protocolsPurpose: make the communication content more secure and reliable in the communication protocol.For example: if you need to customize a communication protocol, the most basic thing you need is a frame header and frame tail flag, only the recipient of the communication knows when the communication starts and ends.

These protocols can be implemented by any object that complies with certain conventions.There are two protocols: the iteratable protocol and the ite

to send IP groups that do not know where to send them. In this way, the router correctly forwards IP groups that know how to transfer them, and the IP groups that do not know are sent to the "Default Gateway" router. In this way, the IP Group will eventually be sent to the destination, IP groups that cannot be sent to the destination are discarded by the network. Currently, all TCP/IP networks are interconnected through routers. The Internet is an international network that connects thousands o

DHCP can automatically assign an IP address to each computer in the LAN, complete the TCP/IP protocol configuration for each computer, including the IP address, subnet mask, gateway, and DNS server. In this way, the Administrator does not need to manually configure the TCP/IP protocol for each computer in a LAN, especiall
