routing protocols

, network layer, transmission layer, Session Layer, presentation layer, and application layer are often merged into the upper layer. LAN protocol The LAN protocol defines communication over multiple LAN media. Currently, common LAN protocols include NetBEUI, IPX/SPX, and their compatible protocols and TCP/IP. NetBEUI user extension Interface NetBEUI is a simple, efficient, fast, and rarely used communicatio

readability, and of course the cost of performing additional computing tasks after message acceptance.WAMPThe WEB Application Message Protocol (wamp,web application Messaging Protocol) [9], which attempts to develop an open, text-based protocol standard, combined with a publish-subscribe-based request/response programming model, It also has a powerful routing and message delivery strategy. It is now widely used for the integration of CROSSBAR.IO[10]

Description: After the use of IP to identify each network node, if the two nodes separated by multiple network nodes to communicate, need to "man-in-the-middle" strings, the step by step notice a node data, to go to the end of the node step-by-step how to go.Static routing: Manually configure static routing information that can be forwarded using a leased line interface or a next-hop IP address based on the

We use the Internet every day. Have you ever wondered how it is implemented? Billions of computers around the world are connected together and communicate with each other. One Network Card in Shanghai sends a signal, and the other network card in Los Angeles actually receives the signal. The two actually do not know the physical location of the other. Do you think this is amazing? The core of the Internet is a series of protocols, called Internet

metric. Routers communicate with each other and maintain their route tables by exchanging route information. route update information usually includes all or part of Route tables. By analyzing route update information from other routers, this vro can create a network topology. Another example of information sent between routers is the link status broadcast information, which notifies other router senders of the link status. The link information is used to create a complete topology so that the

Static Routing Static Routing refers to the routing information manually configured by the network administrator. When the network topology or link status changes, the network administrator needs to manually modify the Static Routing Information in the routing table. Static

Network layer—The IP protocol belongs to the network layer of the network protocol stack. The functional goal of this layer is to transfer packets from one location in the network to another, which is the lowest level of processing end-to-end transmission. In the middle of the transfer process passes through many hop (hop) intermediate routers, so the routing algorithm is the core task of its design. (but unfortunately not the core task of this articl

The ports and protocols used by the Samba service:1) Port 137 (UDP)-NetBIOS name service; NMBD2) port 138 (UDP)-NetBIOS Datagram Service 3) port 139 (TCP)-File and print sharing, SMBD (SMB (Server Message Block) protocol, mainly used on LAN, file sharing protocol) 4) port 3 (TCP)-for LDAP (Active Directory Mode) 5) port 445 (TCP)-NetBIOS service uses this port in WinDOS 2000 and later versions (Common Internet File System , CIFS, which is the SMB prot

Currently, the vro protocol is widely used. Many people may not know the RIP, HELLO, and egp in the vro protocol. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. Technically, the IGP protocol is the same as RIP and HELLO protocol. Vro uses this Protocol to obtain information about other vro protocols in the autonomous system so as to update its

Network Layer 2 (IPv4 and IPv6 addresses and related protocols) IP (internet protocol) protocol is the core protocol of the TCP/IP protocol family and the network layer of the internet. The current version number is 4, also known as IPv4. The next generation IP protocol version number is 6, that is, IPv6. As described in the network layer function, the IP layer provides the selection and forwarding functions for the Internet. Hosts connected to the In

. This is true, but the access list of the driver routing diagram is also static, therefore, mutual redistribution is no longer dynamic. Mutual redistribution in the enterprise network is usually not a good method. In the network declaration, although the command itself is static, the network Declaration is very simple and easy to understand, so it can lead to very definite behavior. You don't have to guess what your network will do. However, many net

PPTP, L2TP, IPSec, SSLVPN, and other Protocols define and distinguish between VPN (Virtual Private Network). So far, it is no longer a pure encrypted access tunnel, it integrates multiple functions such as access control, transmission management, encryption, route selection, and availability management, and plays an important role in the global information security system. Also on the network, the advantages and disadvantages of various VPN

Ipx/spx Two network protocols are proposed by NetWare company primarily for LAN and network games where the IPX protocol has the full name of the routing function Internetwork Packet Exchange (Internetwork Packet Exchange), the IPX protocol is the most low-level network protocol with Novell NetWare, which is mainly used to control the addressing and routing of p

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. Transmissi

gateway, and to control the network through the access list, or is it easy to use network declarations to configure the Intranet gateway and external gateway. Generally, you do not select Network declarations because the network declarations are static. This is indeed true, however, the access list of the driver route chart is also static, so mutual redistribution is no longer dynamic. Mutual redistribution in the enterprise network is usually not a good method ｡ In the network declaration, alt

With the development of routes, there are many types of routing protocols. So I have studied the practical application and detailed introduction of dynamic routing protocols. I will share with you here, I hope it will be useful to you. As the name suggests, dynamic routing i

PIM-DM intensive mode)The PIM intensive mode is the preferred configuration in the multicast routing protocol. This Protocol is strongly supported by Cisco and provides easy configuration and troubleshooting methods. Similar to DVMRP, the PIM intensive mode does not have the characteristics of flooding or deleting. Therefore, it can still be used as an option for configuring short-term protocols for wide-ar

In the environment of the routing simulation software, the CIDR blocks related to computer work are: ◆ 255.255.255.255 255.255.255.255 192.168.0.111 192.168.0.111 1 broadcast for network interfaces. No matter what network segment you are, LAN or INTERNET, this network segment exists. He is the basis for communication between the computer and the IP environ
