layer 2 network switch

the subnet B. Previously, the S1 switch was directly connected to the core switch of the local area network with an optical fiber cable on port 24. To avoid VLAN division in the switch system, we can change the port operating mode of the S1 and S2 switches. For example, we can first check the port settings of the S1

The network switch technology allows you to adjust the shared and dedicated LAN segments, which effectively reduces the information flow bottleneck in the LAN and ensures the security and stability of our network. In 1993, LAN switching equipment emerged. In 1994, the domestic network

the current broadband network. Multicast exception message: the multicast information serves only some users in the network. The destination address is the host applied to join the multicast group in the network. Some hosts do not apply to join multicast groups. These multicast texts should not be forwarded to these hosts, but in fact these hosts still receive

mentioned earlier, so that they can respond correctly in time for similar problems in the future. First look at the first 4 features: The convergence switch is a network layer device, the building's VLAN network layer interface is set up on this convergence

identity map, why not add this prior to the training network, and then construct the network with the shortcut connection, that is, the output of each layer is not the input map of the traditional neural network, but the mapping and input superposition, As shown in Figure 2

table. By creating a temporary exchange path between the initiator of the data frame and the Target receiver, the data frame can directly reach the destination address from the source address. Now, the switch has replaced the Hub, also known as the Hub, which is a familiar network device. However, this does not mean that we do not need to understand the basic knowledge of the Hub.

operation and management must be more flexible and mobile. Many telecom operators in the world have used H.323's Internet guard or SIP proxy servers and other network application servers for networking, networking, and network-wide business and O M. Recently, the emergence of some new core network technologies (such as ITU-T's Q. GTD1, Q. GTD2), more to illustr

.) legitimate users can reasonably use network resources, prevent legal users from unintentional, intentional, or malicious attacks on the network (such as malicious download of BT), prevent a large amount of consumption and possession of network bandwidth resources, Block network outlets, and make normal office teachi

Switch selection criteria in Network Monitoring With the increasing use of high-definition cameras, how to choose a suitable switch to monitor the overall network architecture performance has become a very important role in the early design of the high-definition monitoring system and project quotation. A proper

connection mode, weight value and excitation function of the network. The network itself is usually the approximation of some kind of algorithm or function in nature, and it may be the expression of a logical strategy.The advantages of artificial neural network are obvious, mainly embodied in the following three aspects:1. With self-learning function2. With Leno

Switches are constantly evolving along the speed, multi-layer switching, and intelligent exchange directions. A new trend is that intelligent exchange at the edge access layer drives the development of intelligent exchange from the core of the network to the edge. In the past, the network architecture only adopted
