more attractive than Cisco's User Conference. The reporter also noted that although Cisco has prepared up to 14 special forums for security topics, several special forums on vro technology have always been arranged in the main venue where more people can attend. Before Cisco's 20-year history and Cisco's China's 10-year history, the only physical display was Cisco's first router. The eternal focus of router technology is constantly changing. At this User Conference, cisco presented the exciting

Analysis and Comparison of IPv6 and NAT

Service (QoS) assurance. The IPv6 Header does have some improvement in performance. For example, the checksum field is removed, but this is not the same as the so-called QoS warranty. Currently, the technologies that address IP QoS are DiffServ, InterServ, and Multi-Protocol Label Switching (MPLS), which are applicable to both IPv4 and IPv6. In other words, IPv6 uses the same technology as IPv4 to solve the QoS problem. Without IPv6, the service qual

TDM hosting, and can save 25% to 50% of the bandwidth depending on the length of the packet in different protocols. However, the reliability of router device cannot be compared with TDM switch device, the router device needs redundant configuration, and a fast fault detection and switching strategy is needed. Although the QoS of IP network can be improved through MPLS, Dfferv and other technologies, the real-time performance of the network can not be

New Broadband Access Network Technology Transformation

There are many ways to access the broadband network. At the same time, these methods also use different access technologies. Each new technology can solve the problem that the old technology cannot implement, here we will introduce the features and principles of these technologies. Last step Since June, China Telecom has opened a VPN service for major customers on the newly created CN2, marking the maturity of a new IP bearer network. This bearer network not only adopts the latest technologies

OTN switching & P-OTN effectively reduces network cost by 100 GB (2)

the addition, deletion, and redistribution of services do not require manual intervention on the intermediate node. On the contrary, the remote implementation can be achieved through OTN switching configuration. The results not only greatly save OPEX costs, but also allow network operators to quickly make profits for high-value differentiated businesses. Improved network Elasticity The sub-wavelength processing and the ability to dynamically allocate clients to WDM uplink ports also allow netwo
