Huawei AR100 series, petite size has two slots, the expansion of business areas have a great advantage
what factors should be consider to choose a modular router?
Buy modular router, considering the current business needs at the same time, the future demand, the future capacity expansion, equipment performance, scalability and maintenanceof the type, firm board should be taken into account. After all the network equipment to the enterprise investment of money, but most company daily business operation, therefore need to goods than three, carefully chosen.
Below we will mainly from the hardware, the selection module router that we should consider what.
1 forwarding performance
The forwarding performance, sometimes also called throughput rate, is one of the keytechnical parameters of router. The main function of the router is to do IP packet forwarding,the router uses the CPU software to realize the function, therefore the most low-end routerdoes not have the line speed forwarding capability.
The router layer three forwarding rely mainly on CPU, are integrated in the main control boardrouter. The main control board is the core of system control and management, provides the control plane of the whole system, management level and service switching plane. The main control board, the industry many vendors have a variety of main control board in the high-endrouter selection.
The main control board in different grades, determines the current business, also affect thefuture expansion
Huawei AR G3 series of high-end routers, provides the main control board differentforwarding performance of 2~40Mpps, offers a variety of options
The main control board, the most concern is the packet forwarding performance andinherent WAN export. The forwarding performance is reflected throughout the equipment data packet forwarding capability of inside and outside, the main performance is higher, canbetter adapt to the future development of large bandwidth, meet the needs of the future 3~5year upgrade requirements. In addition to the WAN port, a decision the export bandwidth, itsmain control WAN port number fixed plate, on the other hand, the follow-up can also reduce the investment on WAN single board. At present, Huawei AR G3 router control board can support multiple 2~40Mbps forwarding performance, the return on investment has very highprice.
2 The expansion ability
Extending the number of slots number directly affects the future routers can have expansionability, if taking into account the subsequent business expanded rapidly, choose a high-end,easily extensible router is absolutely a wise choice.
The flagship AR3260 router Huawei launched in 2011 to reach 10 slot, slot
If the slot and focus only on the number of words, that is not enough. Router slot is always limited, limited slots needed to support board business unlimited to! How reasonable,efficient use of the existing slot, to expand the business, the purpose of saving investment,many enterprises is concerned.
Huawei AR G3 router, a standard modular design:
A small groove in the slot in the slot with variable, with large slot, slot can be flexibly combined
At present, the access router card in the slot, it is difficult to do general (such as two smallslots can be combined into large slot, you can plug a kcal), and a part of many routers orspecial card slot for. Currently on the market completely slot can be combined, the boardonly common Huawei AR G3 series.
3 business card
Now, access route not only supports the E1, SA and other wide area net card, and with thedegree of integration and ALL-in-One device concept, the two layer switching card, voice card, PON card and so on have access.
Exchange board 24 Gigabit Ethernet Huawei AR G3 support switching port, friends are shocked!
"Sounded the alarm security prism gate" incident on the network, the cryptographic card(data encryption card) is sometimes necessary
Even the same type of card, manufacturers will access density customized various, different access density board different price, buyers can choose according to needs and their own funds.
The same is to realize the function of E1 AR G3, Huawei can provide 1, 2, 4, 8 ports of theE1 card
The board is unceasingly rich, on the one hand makes the original router business greatly expanded at the same time, but also reduce the number of equipment, simplify the network management. Huawei AR G3 currently has as many as nearly 50 kinds of business cardsare available, including the common E1, SA, Ethernet two / three layer, voice card etc..
4 The board hot swap
The board support hot plug, which was originally proposed to telecom equipment requirements. But now with the enterprises and units of office IT comprehensive popularization, the network caused by interruption losses are increasing, more and more attention to the reliability of equipment.
Therefore, for large and medium enterprises, or router network location where the critical(such as access to the key server), the board support hot plug is essential. When a router on the part of the board in the event of a failure or expansion needs to be replaced, do not needto cut off the power of the equipment, direct online card replacement treatment.
To achieve without power to Huawei AR G3 router, hot swapping business cards.
T above is the access level modular access router needs to pay attention, these factors are also the router vendors in the strength of the most important factors. In addition to the factors mentioned above, simple richness, management and maintenance of software functions and protocols supported by (Web network), whether to support the redundant power supplies, and memory are the factors that need to be considered.
Huawei AR G3 series routers not only in several of the above mentioned showed excellent,relying on Huawei in the telecommunications industry, technology accumulation, theequipment reliability, ease of use and richness of business support are leading the industrylevel, and rich, convenient choice, price is relatively high, is the choice of enterprise Huawei NE40E (http://www.huanetwork.com/
