CCNA Study Notes 13-WAN pppWAN is a type of data communication network over the LAN geographic range. Enterprises must purchase services from WAN service providers. However, a LAN is generally classified as a company goods organization that uses a LAN to connect devices across the WAN to a wider range of geographical areas than a LAN.

As IT continues to effectively centralize services, the dual-hot standby mode of data centers is becoming more and more common, and the network traffic of internal data centers is becoming more and more important. However, as backup traffic increases, virtual machine migration, service-oriented architecture, or replication between storage arrays, the business volume generated between data centers increases.
At the same time, the company's expectations for performance are also increasing: enterpr
How the ICMP ping test works
Ping is a dedicated IP network tool that Ping sends an ICMP echo request message to the destination and reports whether it receives the expected ICMP echo response. Each operating system has the Ping tool installed, and any common enterprise platform, like Windows or Mac OS X, can find it.
You can run the Ping delay test on any network device. The target host can be any other device, such as a computer, a router, or any device with an IP address on the network. In
to ensure the proper protocol is used, the router must be configured with the appropriate layer 2nd encapsulation.The choice of the protocol needs to be determined based on the WAN technology and communication equipment used. The router encapsulates the packet in two-layer frame format and then transmits it to the WAN link. Although there are several different WAN

Recently there are several small networks that use small bandwidth access, so there are a lot of lines, but there are not many machines that he carries. In this case, the price is a bit high when using the PC version, whether it's hardware, authorization, or electricity! If you do not use the PC version, you can only use hard routing. At this time, BCM is the first choice. I will tell you my research experience on BCM Wan Port Extension.
