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. Multi-Protocol Label exchange Multi-Protocol

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

The reliability of metropolitan area Network router is embodied in the following two aspects, one is the reliability of the equipment layer, the other is the reliability of the network layer. The network reliability is an important content of the reliability guarantee of metropolitan area Network router, because the traditional router protocol converges slowly (IGP in the second level, BGP in the minute level), can not meet the demand of carrying real time service. Network rel

destination. MPOA uses the Distributed Virtual routing technology to connect the ATM subnet and edge devices of the traditional LAN subnet, similar to the interface card of the virtual router, the entire ATM network connected to the edge device is the forwarding backplane of the virtual router. The Group forwarding function is separated from the routing computing function. The routing computing function is completed by the Routing Server. This separation improves forwarding efficiency and throu

The VPN support capability should also be concerned. Encryption Method The router may use the encryptor mechanism in VPN implementation or other conditions to ensure security. Router technology uses CPU to execute software algorithms, which usually affects forwarding efficiency. Some router technologies adopt hardware encryption to impro

Some routers adopt hardware encryption to improve forwarding efficiency. Router function indicator: MPLS MPLS technology is described in the router technology above. In addition to label switching,

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. IETFGMPLSUNI Because a large number of SCNET/SDH-based network structures are installed, oper

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

mode designed specifically for high-performance, highly scalable IP backbone networks. 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

By integrating IP and optical network technologies, we strive to improve service efficiency and develop advanced services. However, first they need to overcome extremely complex multi-layer architecture. That is, the IP address on the third layer is extended to the optical transport layer on the first layer.The general Multi-Protocol Label exchange GMPLS is designed to meet the above requirements. The approach adopted is to extend the network intelligence to the network edge through the network

Communications Service Providers (CSPs), including operators, managed service providers and cable operators, now face the challenge of securing service revenue and profits in commercial broadband, such as high-speed, inexpensive Internet services. The software-defined wide area network (Sd-wan) solution seems to be a great antidote for communication service providers to improve the value of managed services for users.CSPs has about $40 billion a year in profits from WAN services, including

Not because I can't go to 1.1.1.1 and 5.5.5.5, but my next-door brother R2,r4 know, is there a way to let me just drop the bag to my next-door router?That's MPLS!!!
