Perspective NP Firewall

What needs to be clear is that all the products on the market that are known as NP firewalls are not really NP firewalls, such as high-end X86 CPU architecture, multi-core CPU architecture firewall, in fact not a real NP firewall. The user must carefully carry on the actual test to the equipment. The test can be based on universal network test equipment such as smartbits or Ixia. Testing and the use of the actual environment, is to identify true and false NP firewall touchstone, as long as the simple performance test, many counterfeit products will be "betrayed."

Really based on the NP architecture of the firewall in performance has good performance, generally speaking, true NP firewall in the throughput rate can reach 64 bytes of small packet speed forwarding, the number of concurrent connections to more than million, processing delay in 20 microseconds within.

Where does the fake NP firewall come from?

Some of the so-called NP firewalls often take one of the following methods in manufacturing: 1. Although the use of NP chip, but not based on the micro-engine to achieve firewall functions, but to pass it to the control CPU to do; 2.OEM some of the immature products of some small companies in foreign countries; 3. Although some of the independent development, but did not master the whole line of core technology, product stability Sex remains to be examined.

Using the first method to produce false NP firewall, its final trial effect and X86 system is not fundamentally different; for the latter two ways to create a firewall, once the user in the use of the problem, the manufacturer is difficult to quickly and accurately give the solution.

How to achieve a high performance NP firewall

How can we develop a true NP firewall with stable performance and high efficiency? This mainly depends on NP chip selection, hardware board design and production and software development three elements.

NP chip selection. As a special chip for network data communication, NP has many ways in architecture and design implementation, so it also appears a variety of NP chips. Choosing a different NP chip will have a direct impact on the performance and security of the firewall based on NP technology. At present, the domestic application in the firewall of the NP chip mainly from the Intel Company's IXP series and IBM's power NP series.

Hardware board design and production. The location of high-end firewall device in network topology is very important, which puts forward high requirements for the stability and reliability of hardware platform. In terms of stability, many of the problems encountered in Low-speed equipment will become particularly prominent in the gigabit speed equipment, such as high-frequency crosstalk in high-speed environments, and in terms of reliability, it is necessary to introduce redundant design of key circuits and disaster recovery mechanism in the design of board cards.

Software development. Firewall is a kind of soft and hard products, hardware platform is good, after all, only to the development of High-performance Firewall has laid a good foundation, as to whether the firewall can eventually become an excellent product, but also rely on the core software to match. Only the hardware and software to achieve the tacit cooperation, will eventually achieve high-quality system.

Lenovo Network Imperial Heart to create high-end NP firewall

Lenovo Network Imperial in the initial stage of deployment of NP high-end firewall, fully analyzed the various technical problems based on the NP development firewall, carefully adopted the IBM Power NP network processor nps43c, for the successful development of NP firewall has laid a solid foundation. In the NP firewall hardware board design and production, invested a lot of resources, carry out independent research and development, on the basis of detailed analysis of the characteristics of nps43c technology, the use of telecom-grade network equipment board design Technology optimization and innovation, mastered the high-end firewall hardware board design core technology. In the software development aspect, the Lenovo network Royal starts from 2001 project launches, has carried on 4 years of microcode development experience accumulation.

Lenovo NET NP high-end firewall thick thin hair, in the successful launch of the network Royal 7000 series of NP gigabit wire speed firewall, and recently successfully launched the network Royal 9000 series million trillion firewall. This fully proves that only really mastered the core technology of NP firewall development, conform to the objective law of NP firewall development, can make contribution to the healthy development of the domestic high-end wire-speed NP wall market.
