View the practical functions of soft Routing Technology in routing applications

With the development of the routing technology, the application of the soft routing technology is also more mature and stable. Many people use the soft routing technology, but it also brings problems such as disconnection, connection failure, and slow speed. This time I want to talk about the hardware used for soft routing. I hope it will help my friends who have encountered the above problems.

Soft routing is not only designed to save costs, but also to achieve the perfect functionality and more stable performance that hard routing does not have !!! However, the importance of routing cannot be ignored because it saves too much cost. Some important components such as network cards and electronic disks should not be cost-effective. Compared with hard routing, what we need to do is, only a little bit, but the effect is completely different. The soft routing technology uses a gigabit Nic to greatly increase throughput. In the future, we hope more and more people will select Gigabit NICs for routing. First, let's get to know the Gigabit NIC: the most important thing is the NIC. There is no need for Mbit/s, and now the fiber optic solution is quite mature. I believe that there will be fewer and fewer network adapters in Internet cafes. We recommend that you use network adapters with more than intel82559 for routing, the best Gigabit route Nic is intel82550GY. 559 many people say it is the best, but it is actually the cheapest and most widely used network card in intel.) The gigabit network card can be divided into four groups based on the overall performance.

The first group member is broadcom5703, intel's pcie Gigabit Nic pro1000pt, pf and broadcom's pcie Gigabit Nic 5751. There are only three vendors that can develop pcie NICs, ibm ?) All are not fuel-saving lights, so high performance is not necessary. It is worth noting that the 5703 Nic is the current performance of the pcix Nic, leaving the other pcix Nic behind, and the performance is directly forced to pcie Nic, is my recommended product.

The second army is a clear intel Nic, including 82544ei, 82545em, 82545gm, 82546 gb, 82546eb, and csa bus 82547ei. The performance of members of this army is extremely close, the most notable feature is that the overall performance in windows is higher than that in other manufacturers' pcix NICs, at least 15% of the gap, but the performance in linux is mediocre, it can be seen that the wintel alliance in network devices is stable.

The third group is a network card headed by the marvell chip. The main chips include yukon8010, DP83820BVUW, AltimaAC1001, RealtekRTL8169, broadcom5700, and 5701. These network cards provide average performance in windows, intel's card completely suppressed, but in linux, the performance surpassed that of the Second Army.

The fourth group uses a pseudo-gigabit NIC with a pci interface. Its main chips include 82540em and 82541pi, 8169netcore of some common pci interfaces), and marvell8001tplink) and 8007dlink ), via's Gigabit chip Xuan Ren ambition and annett's main push), these NICs are best not to be used as server NICs, home is still relatively affordable, among which intel's two chips have the best performance.

The intel Nic is also the best route Nic In the gigabit network. The high speed and high stability are far higher than those of other NICs. Even if we use a pseudo Gigabit Nic like 82540EM82541PI for soft routing technology, it is also a good choice! There are not mentioned in the Article intel9300PT9400PTPCI-E type network card, almost is the top of the gigabit network card products! I hope to have the opportunity to access it. Next, a higher-level optical fiber Nic, such as intel82543ei82546GB, has a corresponding Optical Fiber card, but it is enough to achieve full Gigabit duplex too early in terms of Routing ). Therefore, the optical fiber Nic has almost no application in routing.

Finally, I would like to say to a friend who chooses to route the network card here, instead of selecting 8139 or 8169 categories of crab products for a small cost, if you are using these routes, you may need to change the network card as soon as possible! ~ Haispider has commented on 09 that "we do not recommend using Realtek NICs such as 8139 and 8169 for routing ".

In terms of file system storage in soft routing technology, many people use honest or old-style small-capacity hard drives. I recommend using an electronic disk or high-speed USB flash drive, which is higher than hard disks in terms of heat dissipation and stability, the space required for installing a soft route is smaller than MB ). You can purchase an electronic disk in the Computer City or online. MB plus 3-year warranty only costs 80-90 yuan. If you use a USB flash drive, please use a stable and well-known USB flash drive, such as fake SONY, fake Lenovo, and Tsinghua Ziguang sold in some places and on the Internet. There is no problem in selecting products with high stability for the motherboard and memory. Generally, the motherboard With integrated graphics card is used. The intel Platform is relatively stable, from 845 to P45. The memory is larger than MB, and 1 GB is enough. Choose any power supply for the chassis, and ensure stability. The route should be properly placed in the ventilated location.
