1, Network layer Responsibilities:Responsible for forwarding packets between different networks (based on IP address), not responsible for retransmission, not responsible for the order.Note: During the two host communication process, each packet selects a routing path individually.2, the router can see the IP address, so work in 3 layers. The following application tiers (hubs, switches, routers) are not poi

DHCP server is correct and whether the network traffic is routed correctly. At this time, the network connection has been tested, so the computer can re-connect to the network. For persistent network connection problems, it is best to use an online connection tool between t

VPN internal use of the private address of the Internet. A VPN must have at least one router with a legitimate global IP address in order to communicate with another VPN on the system over the Internet

mask, so that it is convenient to obtain the IP address of the network address, and do not need to find the routing table. A subnet mask is an important property of a network or a subnet. In each item of the router's routing table, in addition to giving the destination network address, you must also give the subnet mask for the

creates a connection across a link, the network specifies a time slot for the connection in each frame. These slots are used exclusively by the connection and a single timeslot transmits the data of the connection.3. Packet switching4. Packet switching vs. Circuit Exchange: Statistical multiplexing5. How groups form their pathways through a packet-switched network6.ISP and Internet backboneIv. delay, packet loss and throughput in packet switching net

replace people's feelings. Online transactions of virtual products can be directly realized, such as the purchase, transmission, transmission, and receipt of text and audio/video. However, even things larger than sesame seeds must be delivered by people. This is the limit of network development. It can surpass people in terms of virtual and sensory aspects, but it will never replace people in terms of physical feelings. 1. Data Communication In moder

. Hybrid Routing protocolHybrid routing is a combination of the prior routing protocol and the reactive routing protocol, which uses a priori routing protocol in local scope, maintains accurate routing information, and can reduce the range of routing control message propagation. When the target node is far away, it uses the reactive routing protocol to find the discovery route. The ZRP protocol is the representative of a hybrid routing protocol.The ZRP protocol is a tiled routing protocol design

The computer communication network involves two fields of communication network computers. The communication network provides necessary means for data transmission and exchange between computers. Computer technology permeate the communication

responsible for all wireless network functions, equivalent to a computer modem. Just this modem is using radio waves instead of telephone lines.The baseband processor is a consistent, but often delayed, resource. The Fast wireless network is an incredibly complex thing, and the complex signal processing that it requires leads to a fixed, guaranteed delay, in mic

In computer networks and IDCs, the unit of bandwidth rate is expressed in BPS (or B/S). The conversion relationship is 1 byte = 8bit.1B = 8B ---------- 1B/S = 8B/s (or 1bps = 8bps)1kb = 1024b ---------- 1kb/S = 1024b/s1 MB = 1024kb ---------- 1 Mb/s = 1024kb/sIn actual online applications, when downloading software, you often see the words "Bandwidth speed", such as KB (kb/s) and 103kb/s, because the ISP's

With the popularization of Wireless terminals, more and more devices need to use wireless networks. For enterprises, deploying wireless networks is imminent. Now wireless Internet access has become a popular trend. for small and medium-sized enterprises, due to its ease of use and low investment, wireless networks have gradually become a new trend in the Internet
