switching core network, which can support up to 144KBIT/S packet data service. The Group control function block (Packet controls function,pcf) mainly acts as the interface between the RF part and the packet Network (IP network), while the Packet Data Service node (Packet Data Service NODE,PDSN) acts as the agent of the mobile IP, It has the functions of establishing, maintaining and terminating the PPP connection and authentication, authorization and billing of mobile users. Among them, MSC fo

Starting from this year's day, Google launched a new auction users free advertising fee activities, the amount of 350 yuan. In other words, now the new registered Google Auction account can be free to get 350 yuan of advertising costs. This is a difficult business opportunity, because Google does not often engage in such activities, and this time Google did not large-scale advertising, the author is also th

problems that previous stackable switches do not face. The first problem is stack bandwidth. We know that the forwarding capability of a vswitch usually enables line rate switching between ports. But what is the stack bandwidth between vswitches? Let's look at the vswitches on the market today. The stack bandwidth is usually 1 Gbps. The BayStack470 of the Nortel Network provides Gbps stack bandwidth. But when the traffic across vswitches is large, do

all situations. In fact, if the vendor calculates the price per port based on the configuration that does not meet the actual conditions or makes other assertions, it may mislead users to judge a product based on the price. Challenges facing stack Technology Today's traffic models are becoming more diversified, such as instant communication between voice and images, which leads to a dramatic increase in client-to-client access and traffic between edge switches. These are all the problems that

In automated analysis of data flow, Alpha break settings can set output filtering for knowledge-discovery algorithms such as automatic interaction detection of X-squared distributions (Chi square Automatic Interaction detection,chiad). Such algorithms themselves are unable to provide detailed guidance on discovering truly useful patterns.

Such an algorithm itself is unable to provide detailed guidance on discovering really useful patterns. A new poll. Another interesting application of one-way X-square distribution testing is to re-examine polls to see if people's responses have changed.

Device vendors have released their own proprietary protocols for managing layer 2 network conditions, such as Cisco's CDP Protocol Cisco Discovery Protocol) and Extreme Networks's EDP Protocol Extreme Discovery Protocol) enterasys Networks's CDP Protocol Cabletron Discovery Protocol) and Nortel Networks's NDP Protocol Nortel Discovery Protocol. CDP developed by Cisco is widely used in CISCO products. CDP

Jtapi is essentially a set of reusable voice call control objects that can be used in some Java-based telephone applications, these telephone applications can run on any computing machine with a Java virtual machine and a jtapi telephone subsystem. Because jtapi is based on Java, jtapi objects are independent of any operating system and hardware platform, thus supporting c

? Microsoft estimates that it will speed up its acquisition of Nokia. 6. $12.5 billion is not expensive? Look at Apple's patent acquisition of Nortel, nearly $5 billion, Microsoft's acquisition of Skype $8.5 billion, interdigital's patent reference of Nortel will certainly exceed 5 billion, so it seems that 12.5 billion is not expensive, however, it is estimated that interdigital is depressing. At least it

Mr. Zhang, a white-collar Member of the CBD, is preparing a Channel Partner communication meeting for the company recently. He thought that he had mastered at least two contact methods for each representative. The preliminary contact at the Meeting would be very easy. However, during the contact process, he found that he only had some "Chaotic" numbers and letters in his hand. The more communication means, the more complex the contact is, "Unified Communication", a solution that integrates acces

Communication Market. In this case, voice becomes "another application on Data Infrastructure", and traditional desktop devices are replaced by softphones and mobile devices. Therefore, there is less and more debate on PBX hardware. Major ip pbx suppliers, including Avaya, Cisco, Nortel, and Siemens, have formed their own unified communication solutions, at the same time, they realized that it was necessary to establish a connection with the Unified

power monitoring circuit monitors the changes in the optical power value of the active and standby optical fibers in real time. It has a built-in photoelectric sensor and a 1 × 2 optical splitter. The optical splitting ratio is usually 97: 3, this is equivalent to increasing the attenuation of about 0.25 dB on the transmission line, and is suitable for online applications. The optical switching circuit has a built-in 1X2 or 2x2 optical switch, which is controlled to automatically switch between

to maximize the security of VoIP are as follows: 1. Isolation of networks for voice and data transmission The isolation described here does not refer to physical isolation, but it is recommended that all IP phones be placed in a separate VLAN while restricting unrelated PC terminals into the network segment. The feedback from many reviewers shows that the VLAN is the most simple and effective way to protect the IP voice system, and can isolate viruses and simple attacks. At the same time, wit
