802.11ac and 11n standard? To put it simply, the 802.11ad standard, also known as Wiig, can be considered as the next generation standard after 11ac and 11n. Compared with 802.11n (working in the GHz and 5 GHz frequencies) and 802.11ac (working in the 5 GHz frequencies), 802.11ad operates in the 60 GHz frequencies, making it easy to transmit data to 7 Gbps, it is three times faster than the current fastest 11ac theoretical transmission rate (5 GHz ba

The port density can be expanded to 400 10/100 switching ports for each group of stacks, and the layer-3 switching performance can reach 10 Mpps. The combination of P550 and P330 has an end-to-end feature.

To facilitate future business integration and service provision, simplify management, reduce construction costs and operation and maintenance costs, and solve various problems arising from
backboard of A vswitch, the stronger the ability to process data, that is, the higher the packet forwarding rate.The bandwidth of A vswitch is the maximum amount of data that can be transferred between the vswitch interface processor, interface card, and data bus. The backboard bandwidth indicates the total data exchange capability of a vswitch. The unit is Gbps. It is also called the switching bandwidth. The bandwidth of A vswitch ranges from severa
throughput between the switch interface processor or interface card and bus. The backplane bandwidth marks the total data exchange capability of the switch, in Gbps, and the backplane bandwidth of the general switch ranges from a few Gbps to hundreds of Gbps. The higher the backplane bandwidth of a switch, the stronger the ability to process data, but also the h
GE switches are still commonly used. So I studied how to use parameters to evaluate the performance of GE switches. I would like to share with you here. I hope this will be useful to you, there are many types of GE switches and manufacturers that support Ge Ethernet technology on the market. How to choose suitable devices among these devices, it is a problem that requires careful consideration, time-consuming understanding, and difficult to weigh the choice.

In this solution, longxun technology A770 is used as the backbone network of ATM 6). It provides 622 Mbps and 155Mbps switching ports. Both P550 and P330 can provide ATM connection, routes are supported at the edge.
In addition to the features of the above scheme, the advantages of the ATM Backbone are as follows: the ATM backbone switch A770 can provide two 40

need to ensure that the IP segment and loopback network segment are interconnected between devices. In some regions, OSPF has been run independently and OSPF needs to be configured on the router to communicate with each other. Therefore, multiple OSPF processes need to be set up to ensure that the network segments of the same access layer are interconnected without redistribution. The access layer CIDR Block route is advertised to the backbone network through BGP on the router.

, if the packet traffic is high, excessive interruptions will increase the system load.
Round Robin
If the polling method is used, you do not need to enable the interruption status of the network device or register the interrupt handler. The operating system will enable a task to regularly check the BD table. If the current Pointer Points to the BD not idle, the data corresponding to the BD will be retrieved and the BD will be restored to its idle state.
Because the principle of regular task che
Many Webmasters have misunderstandings about restricted traffic and unlimited VPs. This article will introduce some basic concepts and use some practical cases to explain the differences between restricted traffic and unlimited traffic.
When purchasing a server in the U.S., there are two options:
1. unlimited bandwidth and traffic restriction:
That is, Mb is exclusive and the traffic is limited to GB. If the traffic exceeds 2000 GB, another traffic fee is required.
2. limited bandwidth,
