Frame-Rekay ): Frame relay is a connection-oriented service. It is an industry standard pure L2 data link layer protocol. It uses HDLC encapsulation between connected devices and can process multiple virtual circuits (VC; frame Relay is more effective than X.25. Currently, it is generally considered that frame relay should be used to replace X.25; Virtual link VC (Virtual Circuits): Permanent Virtual link PVC (Permanent VC) and switched Virtual link SVC (Switch VC); Virtual link must be cons

technology of the current vro for data forwarding at line rate. Programmable ASIC integrates multiple functions on a single chip. It has the advantages of simple design, high reliability, and low power consumption, so that devices can achieve higher performance and lower costs.The use of ASIC chips can also increase the port density of devices. The port density of an ASIC chip is several times that of a General chip.The design of the programmable ASIC chip is the hardware guarantee implemented

Editor's note:This article will give you a detailed introduction to all aspects of the vro, including the vro type, vro configuration, route protocol support, multicast support, and vro performance.DirectoryRouter typeRouter configurationRoute Protocol SupportSupports the list protocol for multicast)Router performanceQoS capabilityGroup speech capability Router type This table mainly compares whether the vro is a modular structure. Vrouters with a modular structure are generally highly scalable

Interface Type The types of interfaces supported by the vro reflect the versatility of the vro. Common interfaces include: common serial interfaces are converted to RS232 DTE/DCE interfaces, V.35 DTE/DCE interfaces, X.21 DTE/DCE

With the development of China's routing industry, it also promotes the upgrade and upgrade of the router technology. Here we mainly introduce the router interfaces that are frequently used in the router technology, and the types of interfaces supported by the router, represents the versatility of routers. Common interfaces include: common serial interfaces are converted to RS232 DTE/DCE interfaces, V.35

I have learned a little about vro configuration, so I have studied the performance indicators of vro configuration. I would like to share them with you here, hoping to help you. This table mainly compares whether the vro is a modular structure. Vro configurations in a modular structure are generally highly scalable and support multiple port types, such as Ethernet interfaces, Fast Ethernet interfaces, and high-speed serial ports, the number of ports of various types is usually high.

We all know that computer networks are divided into seven layers, each of which has its own network communication protocol. We can easily understand the concept of network communication protocol. However, it contains many protocols. Here we will summarize several important protocols to help you make a summary. See the text below. Network Communication Protocol 1: ◆ RS-232-CRS-232-C It is the specification of the OSI basic reference model physical layer. It determines the physical characteristics

.What are the main features of a simulated transmission system and a digital transmission system? A: analog signal transmission is used to simulate transmission systems. During transmission, noise is added in. After signal attenuationAmplifier AmplificationBecause both the signal and noise are amplified by the amplifier, the final signal will be distorted. The digital transmission system uses digital signal transmission. noise is also added during transmission, and the pulse signal waveform
