effectively guaranteed. However, this does not mean that the IP network's QoS has been solved once and for all. In fact, the most close-to-user broadband access network is the difficulty and focus of IPQoS. "In the future, if a carrier wants to provide more services to home users, QoS at the access layer must be resolved. from the current situation, there is not much problem with carrying only a single data or video business. However, once the business is enriched, especially the integrated bus

replace the traditional TDM return network. A key technical requirement is high-quality transmission of reference clock signals, to ensure the stability of clock signals. The ON technology can meet the technical requirements of traditional base stations. First, the GPON platform can transmit the reference clock in the physical layer in NTR mode, and secondly, GPON can meet the latency and jitter requirements for transmitting real-time traffic, this is mainly due to the flexible deployment of Qo

Wireless cats may sound fresh. In fact, such products are still widely used among users, but they are not as popular as routing. In contrast, many users do not set up wireless cat Internet access. This article will briefly introduce the relevant process. In wireless networking, especially in home wireless networking, the basic construction structure is relatively simple, let's first take a look at the network structure of the home wireless Internet access and then describe the wireless cat Inte

world, such as Nokia, 3COM, CISCO, Siemens, Alcatel, Paradyne, have successively launched ADSL products and are committed to the development of ADSL; many telecom companies and ISPs around the world have also promoted their respective ADSL Services. North America and Singapore are the first to officially open their business. Japan, South Korea, and other countries have entered the trial phase, china Telecom has carried out relevant network tests in B

Unified Communication and user business systems is not as urgent as the development of other functions. The reason is that many users do not have a deep understanding of the changes that can be brought about by the integration of the business system into the unified communication function, and there are few such successful cases. Therefore, unified Communication vendors should increase the deep application of Unified Communication in user business systems and accumulate relevant success stories

Nokia Siemens Network (NSN), a mobile telecom device manufacturer, announced on Monday that it plans to sell its optical network business to Marlin Equity Partners, according to a message on August 1, December 4, Beijing time.

Huawei leadership. In addition to H3C, 3Com has a majority of its value in its Tipping Point Department, which provides network security design. 3Com had previously expressed its intention to split the Department to public, but the plan may not be implemented after it was acquired by Bain Capital and Huawei. Bain Capital has launched extensive acquisitions in recent years, while Huawei is China's largest telecommunications equipment manufacturer. Huawei's business has rapidly expanded globally,

capabilities are the reasons why Huawei supports this standard. Like HP, Huawei plans to expand and bridge the SPB and TRILL features. Wilcox said that Huawei recognizes that neither IETF nor IEEE standards have all the functions that every user needs. We will work with other vendors to study these two standards to help users make up for these shortcomings at the lowest possible cost. Considering the basis of its own carrier, Avaya and Alcatel-Lucent

improve the activation rate and communication quality, the access products provided by the Telecom Department are basically used, and the Telecom Department sells the products to users at the cost.20. Which vendor's ADSL devices are currently used?Currently, Alibaba Cloud products include Alcatel, Ericsson, Huawei, ZTE, And Hewitt. For specific device types in your region, contact the local telecommunications Bureau.21. What are the forms of ADSL cli
