transmission network that is interconnected by multiple manufacturers. In addition to dynamic control over Ethernet private line services, SUPPERCOMM05 also includes transmitting Ethernet virtual services through optical transmission networks. The client network can use the UNI2.0 signaling interface to control a 1-bit Ethernet Access link to dynamically request connections from the carrier network. 2.

offices, international regions, remote computers, roaming mobile users, and business partners due to business requirements, or the network structure is changed, enterprises can expand their VPN capacity and coverage at any time by relying on the ISP that provides the VPN service. VPN has an absolute price advantage over the leased line. Compared with ordinary PSTN dial-up connections, VPN is superior in terms of security and confidentiality. The Traditional VPN is basically built on Frame Rel

At present, telecom enterprises are seeking to integrate IP and optical network technology, in order to develop efficient advanced business. The first thing to overcome is the high complexity of IP services that are designed to support voice and fixed-circuit multi-tier architectures, resulting in the need for a control plane that extends from Layer 3 IP to layer 1. The goal of the GMPLS (Universal Multiprotocol Label Switching) technology is to cater to this need, and to extend the intelligenc

technology below the IP network layer, that is, the WAN technology mentioned above. In general, the topology of the core network is basically a large ring structure with a self-healing function, and the specific encapsulation can adopt various technologies, but almost no direct IP address encapsulation, because IP exchange is not a real exchange, it requires additional computing in it. These additional computing is routing search and address resolution. The core network exchange is basically a

Differences between hybrid WAN and SD-WAN, wansd-wan differences The concepts of hybrid WAN and SD-WAN are often misused, and some people think they can replace each other. Hybrid WAN is a way of routing traffic across multiple connection paths, software-defined WAN (SD-WAN) Simplifies WAN management by centrally managing and providing business policy orchestration and security. These two methods have evolved into an important technology that supports the changing network needs of the cloud era

Different hybrid WAN and SD-WAN in cloud computing networks, hybrid wansd-wan The term hybrid WAN (WAN) and software-defined WAN (SD-WAN) are often incorrectly considered interchangeable. Hybrid Wan is a practice of routing traffic on multiple connection paths, while software-defined Wan (SD-WAN) Simplifies the management of hybrid Wan by centrally managing and providing business policy processes and security. These two methods have evolved to support the ever-changing network needs of the clou

priorities to different services, and assign different network resources to services with different priorities. Therefore, ATM provides QoS guarantees for real-time services such as conversational sounds and images. Although ATM has the advantages of fast switching speed, traffic control, service quality assurance, and flexible bandwidth allocation, the overhead and Protocol complexity of ATM make the cost of ATM equipment high, complex maintenance.

and allowing routers to forward datagrams based on fixed-length labels (rather than destination IP addresses), without abandoning the infrastructure based on destination IP datagram forwarding, for technologies based on fixed-length tags and virtual circuits.MPLS packets can only be sent between MPLS enabled routers because the first part of MPLS is between the link layer and the network layer header, whic

Operators are seeking to improve service efficiency and develop advanced services through the integration of IP and optical network technologies. First, however, they need to overcome the extremely complex multi-tier architecture. That is, the IP from the third layer extends to the first layer of the optical transport layer. Universal Multiprotocol Tag Switching (GMPLS) is designed to meet the above needs, using the same method: Under the unified control plane, let the network intelligence exte

From the above we can see that in large-scale dynamic IP networks, CEF is able to provide unprecedented exchange consistency and stability. It can effectively compensate for the frequent failure of fast-swapping cache entry, and the DCEF distributed Exchange can make each circuit card exchange completely and provide more superior performance; CEF is less memory-intensive than fast-switched route cache, and ca

the next generation network should be based on the quality of IP-guaranteed Universal telecommunications network. The development of the customer of the network needs not only the optimization of the existing network service, such as the QoS guarantee of the connectionless Network service and the IP service. At the same time, the smooth transition of existing network service and physical Foundation also needs good planning. Although it is very complicated to realize the exchange of multiple ser
