  Why SD-WAN is better choice than MPLS in 2021 Thinking about both of the above technologies in mind, we have to through each of them, including their advantages and shortcoming; we can easily choose which of them can be the best choice in 2020. Before taking a glimpse at both of them, SD-WAN is the innovation that has reinvented the IT networking market. SD-WAN has enabled companies to acquire better control over their networking gadgets utilizing a software-defined solution. Formerly, the standard networks do not enable organizations to have more control over the gadgets since each of the networking devices, including routers and switches, has its own EIGRP, STP, ARP, etc. This indicates that they can be independently communicated; however, utilizing a software-defined technology, they can be more scalable and efficient at the same time. Cisco SD-WAN solutions provide a cloud-based networking architect that can be handled quickly using Cisco’s vManage software application. ...

Today we will consolidate the concept and application of the 802.1X protocol. In traditional corporate networks, it is generally believed that the corporate intranet is safe, and threats mainly come from outsiders. But in fact, the internal loopholes in the network damage the network more seriously. In addition, internal employees lack security awareness and malicious software such as various plug-ins, spyware, and Trojan horse programs will unknowingly be downloaded to the computer and spread on the corporate intranet, creating serious security risks. With the continuous escalation of security challenges, traditional security measures alone are no longer enough. You should consider starting with the security control of the terminal connected to the network, and the security status of the terminal and the network. 802.1x is mainly based on Client/Server access control and authentication protocol. It is mainly used to restrict unauthorized users from accessing the LAN/WLAN network throu...

Today we come to understand the network port mirroring technology. Port mirroring is to copy the packets of the specified port (source port), VLAN (source VLAN) or CPU (source CPU) to other ports (destination ports). The destination port will be connected to the data monitoring device, and the user will use these data to monitor The device analyzes the packets copied to the destination port for network monitoring and troubleshooting. Without seriously affecting the normal throughput of the source port, the network traffic can be monitored and analyzed through the mirror port. Source port: It is the monitored port, and the user can monitor and analyze the packets passing through the port. Source VLAN: It is the VLAN to be monitored. Users can monitor and analyze the packets passing through all ports of this VLAN. Source CPU: The CPU on the monitored board. The user can monitor and analyze the packets passing through the CPU. Destination port: It can also be called a monitoring port. Thi...

PSTN (Public Switched Telephone Network) is a switched network used for global voice communications. This network has approximately 800 million users and is the largest telecommunications network in the world today. In normal life, such as when we use a landline phone to make a call or use a telephone line to dial the Internet at home, we all use this network. One thing that needs to be emphasized here is that the PSTN network existed for the transmission of voice data from the beginning. PSTN (PublicSwitch Telephone Network) is a telephone network commonly used in our daily lives. As we all know, PSTN is a circuit-switched network based on analog technology. Among many wide area network interconnection technologies, the communication cost required for interconnection through PSTN is the lowest, but its data transmission quality and transmission speed are also the worst, and the PSTN network resource utilization rate is relatively low. It also refers to POTS. It is a collection of all ...

If you do yoga, meditate, smoke one by one, or eat a lot of refreshing food when you are nervous, please take a break and do so now, because frankly, the content is harder this time! The voice VLAN function allows the access port to transmit voice data streams from IP phones. When a Cisco IP phone is connected to a switch, it will specify the Layer 3 IP priority and Layer 2 Class of Service (CoS) values in the voice data stream sent; for voice, these two values are both 5, and for For other data streams, the default is 0. If the data transmission is uneven, the voice quality of the IP phone will be reduced, so the switch supports the quality of service (QoS) based on IEEE 802.1p CoS. 802.1p provides a mechanism to implement QoS at the data link layer. In the 802.1Q relay header, the information of the 802.1p field is included. Looking at the fields in the 802.1Q tag, you will see a field named "Priority", which contains 802.1p information. QoS uses classification and scheduli...
