Absrtact: Firstly, the three stages of MSTP technology development are outlined, then the paper introduces the key technologies of virtual cascade, general frame Regulation, link capacity adjustment mechanism and intelligent adaptation layer in the third generation MSTP technology, and introduces and compares the MPLS and RPR technology of the intelligent adaptation layer. Key words: Metropolitan area Network, MSTP,MPLS,RPR I. Overview of MSTP In r

Label:Sometimes, in order for the application to run faster, all that is done is to make minor adjustments here or there. But the key is to determine how to adjust! Sooner or later you'll encounter this scenario: the SQL query in your application doesn't respond the way you want. It either doesn't return data, or it takes a surprisingly long time. If it lowers the speed of the enterprise application, the user must wait a long time. Users expect applications to respond quickly and their reports c

Introduction: XML (extensible Markup Language) means Extensible Markup language, which is already the software development industry most programmers and vendors to choose as a carrier for data transmission. This paper summarizes and introduces several mainstream technologies of Java processing XML, hoping to help developers with different needs to make optimal choices for XML processing technology.Initially, the XML language was only intended to be us

switch, it also supports smart functions that are impossible for layer-3 switches to control network traffic and service quality. Key technologies supported by layer-4 vswitches Different from the L2 Switch, the MAC address and 802.1Q VLAN tags are used to complete the link layer switch process, it is also different from layer-3 switching/routing devices that use IP address information for network path selection to complete the switching process, the

Layer-4 switches are quite common, So I studied the basic knowledge and important technologies of layer-4 switches. I would like to share them with you here, hoping they will be useful to you. With the increasing popularity of Mbit/s, Gbit/s, and even Mbit/s local area networks, broadband MAN networks and even broadband wide area networks are widely used. Whether it is Intranet, exclusive, or residential intelligent networks, it is increasingly expand
