Last year, I started a Seagate Central. There is no time to study, direct plug on the use. Intranet speed has been maintained around 10m-15m. This year 618 changed the gigabit router, the speed of the instant upgrade to the 50m-70m. Cable used are five categories, the heart of the question: if replaced by Super Five class line or six class line, performance can not be improved point??

The physical layer of Gigabit Ethernet is divided into the physical encoded child Layer PCs (physical coding sublayer), the physical Media Connection layer PMA (physical Medium attachment) and the physical media related child layer PMD (physical Medium Dependent) Three Floor The PCS child layer is responsible for 8B10B encoding, which converts 8-bit parallel data received from Gmii to 10-bit parallel data output. Because 10 bits of data can effec

How to install an Intel Gigabit NIC driver in a Linux system-Linux Enterprise Application-Linux server application information. The Linux driver directly downloaded on the intel.net is e1000-5.2.52.tar.gz (the version may change). This compressed package does not contain the compiled. o file. It must be compiled in Linux before it can be used, Because the NIC needs to be compiled, make sure that the kernel source file is installed. The following desc

high speed. In addition to the above main features, the TS3026E layer-3 Switch upgrade product also provides the basic functions of vswitches and vrouters. It includes the IP routing functions of the unicast route RIP/RIP2, OSPF v2, Multicast Route PIM-SM and redundant route VRRP, as well as the basic functions of L2 switches supporting port mirroring and Spanning Tree. The bandwidth of the TS3026E backboard is larger than 15.3 GB, and the switching capacity also reaches 8.8 GB. In general, TS3

For 10 m/m network cabling, you only need to make 1-3, 2-6 cross connections. The other four lines are useless. However, for a gigabit network, the four lines that seem useless have come in handy. You must arrange all eight lines in the correct order. 1.

Recently, a friend asked me: T260 G3 integrated Intel 82567 and 82574 are gigabit NIC, what are their performance differences? The NIC is a device that works at the same time as the physical layer and the data link layer in the OSI Seven layer protocol, so that the NIC also needs two parts of the circuit: the PHY part and the Mac part, respectively, corresponding to the OSI two-layer protocol. PHY part of the circuit is responsible for the number of
