Today in the Webmaster station to see a netizen to write the photo album program, the function is quite simple, see he used the aspjpeg to generate thumbnails, not to recall using aspupload upload, so spent one hours to perfect his code. The following code has a simple comment, if you do not understand, please look at AspJpeg and AspUpload documentation (E, hope to have psychological preparation), can not understand the ask me. Here's the code: Copy Code code as follows: If sessio

H3C S5500-28c-ei H3C: Manufacturer Brand s represents the switch, if the SR represents the business router The first 5 represents the gigabit switch, if 3 represents the gigabit uplink, the hundred trillion downlink. If 7 represents a high-end box switch. 9 represents the core box-type switch The second 5 represents a three-tier exchange or a two layer, greater than or equal to 5 is a routing switch, and less than 5 is a two-tier switch 00 is to distinguish the same category of multiple ser

So, the fiber-optic network card is the name in the end is the fiber port HBA card? In fact, the fiber-optic network card that you often refer to is the HBA card in the Fibre Channel networks. Because of the different transmission protocol, the network card can be divided into three kinds, one is Ethernet cards, the other is FC network card, the third is iS

FTTD (Fiber to the Desk) cabling scheme is attributed to the overall FTTx system, FTTD as a high-level solution for cabling systems, the industry is well aware of the excellent transmission performance of fiber as a transmission medium, but also due to the high price of optical fiber active equipment, Led to few projects in the past few years large-scale use of FTTD wiring. In the rapid development of FTTX access network today, especially the development of FTTH networks, due to the overall indu

function, supports VLAN division, and provides redundant power interface. Although for layer-3 Switch, DES-3326 performance in general, support expansion slot is relatively small, but the low price is also in exchange for good cost effectiveness. DES-3326 switches are suitable for medium and small network core layer and large campus network convergence, providing Gigabit Ethernet modules can be connected to high-speed backbone network, to effectively alleviate network bottlenecks.

to know whether the expected service is available at the outlet. The network owner also wants to know: At what rate can the network be connected? Can this outlet provide power for VoIP phones? Can I access the Internet? Can I use a network printer? DTX-NSM network service module can provide answers. At what rate can the network be connected? In MAC, after the cable Authentication Test is completed, the new link is connected to the corresponding switch port. All services required by end users sh

In addition, you can use NETGEARNMS100 network management software based on the SNMP protocol to centrally manage all network management switches and these smart switches in your network. Like All NETGEAR products, all ports in the ProSafe smart switch series support AutoUpLink™Adaptive and self-Negotiation means that you can achieve maximum performance without using dedicated cables, so that your network investment can adapt to industrial standards-and support any

Example: 3026 2012 5012. The value of 2nd bits is 0 ~ 4 indicates that it is a layer-2 switch. 3550. The fifth digit is 5 ~ 9 indicates that it is a layer-3 switch.

switch kernel becomes a bottleneck for performance implementation; the second is the cross-bus structure. It can establish direct point-to-point connections between ports, which is good for single-point transmission performance, but not suitable for multi-point transmission. The third is the hybrid cross-bus structure, this is a hybrid cross-bus implementation method. Its design idea is to divide an integrated cross-Bus Matrix into small cross matrices and connect them through a high-performanc
