Gigabit Network is a fast Ethernet, its data transmission rate of 1Gbps, still using CSMA/CD access control mechanism and with the existing Ethernet compatibility, with the support of cabling system, can make the original Fast Ethernet smooth upgrade and can fully protect the user's original investment. At present, gigabit network technology has become a new network and transformation of the preferred techn

discovery protocol allows routers to be discovered through IP hosts, but it is not widely used. This means that most hosts cannot quickly know whether the connection between the vro and the connected lan has failed, and it takes a long time for the IP host to detect the connection failure and exchange the replacement vro. Therefore, it is important for any device to improve the network efficiency. Using vro cluster technology can effectively solve some problems. This article introduces the SSR

Solve the problem that Qualcomm Atheros AR8161 Gigabit Ethernet NIC fails in Linux. The NIC Of My Dell I2330R-168 integrated computer broke down after upgrading a kernel version. ifconfig eth0eth0: flags=4163 Now the arch linux is installed, and the kernel is updated to the latest version. uname -a4.4.1-2-ARCH #1 SMP PREEMPT Wed Feb 3 13:12:33 UTC However, this problem still exists. I suddenly thought that I should go to the kernel site to find the

Switch settings would you? Haha, I believe a lot of rookie level of friends do not know, it does not matter the following small set to teach you gigabit network switch settings skills, rookie can also become a network master OH. Run the Telnet client on your computer (this program is available in Windows System with UNIX, Linux systems, and usage is basically compatible, especially in the Windows2000 system) and log on to the remote switch. If we hav

If the server has 4 Gigabit Ethernet cards, how would you choose to design a virtual network of VMware platforms? First, let's look at this virtual network design diagram Production business network requires the use of independent network segment resources, design is very fixed, it is not discussed (production, vmotion and management networks can be isolated via VLANs (two tiers), or through routing isolation (layer three) Vmotion and management

use. The ICMP Routing Discovery protocol allows routers to be discovered through IP hosts, but is not yet widely used. This means that most hosts cannot quickly know whether the router and its associated LAN connection have failed, and that it takes a long time for the IP host to detect the link failure to swap with the alternate router. Therefore, it is essential for any device to improve the effectiveness of the network. Using virtual routing cluster technology, some problems can be solved

The 10-ge core switch is still quite common. So I studied the perfect design concept of the 10-ge core switch and shared it with you here. I hope it will be useful to you. Quidway S8500 series 10-Gigabit core switches are a new generation of high-performance 10-Gigabit core route switch independently developed by Huawei 3Com, it can be widely used in the core layer of the E-government network, the core laye

Of the six Ethernet switches we tested, the Edimax es-5800r and LeaPComm6004 switches are not managed switches, Accton ES4508, and the Thinker3800 switches of the creators are all network-management switches, 3Com 4900 is to support the three-layer and four-layer switch, Shenzhou digital D-link DGS3308TG is a three-tier switch. Performance is the brunt The 6 products include all copper ports, all fiber ports, and gbic ports, of which 3Com 4900 has 12 1000base-t copper ports, Accton ES4508 with

How can network managers implement bandwidth-intensive applications on local area networks (LANs) when budgets are tight and must maintain existing network systems? The latest Ethernet technology, 1000BASE-T (Gigabit Ethernet on the five-type twisted pair) can help network administrators quickly improve the performance of your network in a simple and inexpensive way.1000BASE-T is an Ethernet technology that provides 1000Mbps of transmission bandwidth

When selecting a vswitch, we are most concerned about its performance and whether it can meet our needs. Here we will teach you how to test the performance of a Gigabit Switch and hope to help you. As the core connection device of an enterprise network, a Gigabit Switch provides the primary performance standard to speed up the enterprise network. To help readers better understand the overall performance of

Currently, the mainstream Gigabit Ethernet switches support up to four link aggregation groups and each group has up to four ports. We believe that with the development of the exchange industry, their functions will become more powerful. The best methods to identify the advantages and disadvantages of GE Ethernet switches include: the most direct indicators of functions, application-level QoS Assurance, VLAN support, network management functions, link

. Therefore, the dual-fiber access solution launched by China Netcom is very popular. Introduction to dual-fiber access 1. The optical fiber is directly connected to the Internet cafe, and then the optical fiber transceiver converts the optical signal into a 10 M/M electrical signal. Optical fiber is used for access, featuring fast speed, good stability, low obstacle rate, and strong anti-interference ability. 2. hiper aitai 3300NB router is recommended as the LAN gateway.

Previously, we talked about libpcap packet capture, especially in the case of a gigabit network, which results in a large number of packet loss and a long time of searching on the Internet. This is probably a method like PF_PACKET + MMAP, NAPI, and PF_RING, I tested PF_RING + libpcap and found that the packet capture performance was good under gigabit network conditions, with almost no packet loss. The foll
