supports refactoring. Refactoring is an agile technology, that is, re-constructing code units without changing software functions to simplify design and operations. Klocwork insight provides a graphical representation of source code to display components, blocks, and sub-blocks of the system and their associations and dependencies. It helps you analyze the impact of code. The architecture analysis capability of the code can also be used for "what if" analysis to construct a system with better m
Nick McKeown, a professor of engineering at Stanford University, expects a new network processor to replace the ASIC currently used in routers and switches in the next decade; he said he has gone deep into the future of the Communication Processor: "and if you try to look at it with your eyes, it's like a network-based RISC processor."
McKeown assists in promoting a software-defined network based on OpenFlow communication protocols. Its goal is to generate a series of new software applications t
The full name of WiMAX is Microwave Access for global intercommunication Worldwide Interoperability for Microwave Access). After combining this technology with Microwave devices that require authorization or authorization-free, the broadband wireless market will be expanded to improve the recognition of enterprises and service providers. WiMAX is the 802.16 standard, or Broadband Wireless Access to Broadband Wireless Access, BWA standard ). It is a wireless MAN (WMAN) technology. It is a new air

VoiceXML's execution platform loads the appropriate software and hardware, such as ASR, TTS, for speech recognition and conversion between text and speech. May 23, 2000, the Voice Extensible Markup Language VoiceXML 1.0 was accepted as an example. At present, IBM, Nokia, Lucent, Motorola and other well-known manufacturers have developed a corresponding support VoiceXML products,
technological development, and manufacturers also recognize this bottleneck. At this time, COMPAQ, Hewlett Packard, Intel, Lucent, Microsoft, NEC, and PHILIPS jointly developed the USB 2.0 interface standard. USB 2.0 increases the data transmission speed between devices to 480 Mbps, about 40 times faster than the USB 1.1 Standard, the biggest benefit of speed improvement for users is that users can use more efficient external devices, and peripheral

Uses the local Multi-Point Distribution System LMDS. LMDS was first developed by Cellularvisim, many companies, such as Ericsson, Nortel Networks, Alcatel, Bosch, Lucent, Hewlett-Packard, and Hughes, provide LMDS. The LMDS system consists of base stations, user devices, and network management systems. and the user end are both composed of outdoor units (microwave transceiver and antenna) it is compo
is used in pairs when connecting optical cables, that is, an output (also a light source), an input (input, optical detector ), for example, the optical fiber connection between a vro and a vswitch. If you can use them in pairs without considering the connection direction, and the connection is simple and convenient, it will be helpful for Gigabit Ethernet connections. Therefore, many cable cabling manufacturers have introduced various connectors to meet this application. This new optical cable
bypass the optical fiber during use, which will increase the attenuation of the light during transmission.
After the optical jumper is used, you must use a protective cover to protect the Optical Fiber Connector. Dust and oil stains may damage the coupling of the optical fiber.

feasible solution to provide physical routers to service providers as a service. This service can significantly reduce capital investment and operating costs, and speed up service providers to follow up on the market. For enterprise users, the multi-route technology enables them to establish a real dedicated network RPN. RPN Enables Telecom enterprises to provide their own physical routers and dedicated lines at the price of virtual networks. Enterprises do not have to sacrifice their control,
the test items listed below during the test.
1) Functional testing: It mainly verifies whether the product has every function designed.2) stability and reliability test: Generally, the method of increasing the load is adopted to evaluate and analyze the running capability of the equipment under long and high load conditions.3) interoperability test: different network products must be able to communicate with each other. Interoperability test checks whether a network product works well in a netw
intersection port and in other rooms, the signal must be tested before the dead ends of the wireless signal can be identified.
How does one view the signal strength when the home wireless network is confused?
If your computer is using a Windows XP or Windows 2000 operating system, you only need to click the wireless network status icon in the taskbar to learn the strength of the wireless signal, this is the most intuitive detection method.
In addition, most of the wireless networks connected to
can query the wireless network status in detail and set various functional parameters. Taking Lucent ORiNOCO as an example, using its own ORiNOCO Client Manager management software, you can implement functions such as signal viewing, channel selection, and wireless encryption, which are also very convenient to set.
Some brand computers often have more powerful management software, such as the IBM ThinkPad laptop, using the IBM Access Connection softw
switches and routers that connect users to VNF. However, according to this reasoning, it seems that every resource in the data center or connected to the data center can be considered as NFVI. If so, Alcatel-Lucent, Cisco, Dell, IBM, Huawei, and many other vendors can consider that they can provide NFVI. However, we must stick to our needs before the results are clearer.
Two platforms support NFVI. One is the NFV orchestrator and the other is the vir
