How DCN and SDN meet new requirements New Technology of ip ran Network

How DCN and SDN meet new requirements New Technology of ip ran Network The traditional 3G/B3G network needs the basic bearer network to provide the Layer 2 capability to meet the needs of the Upper-layer network mobile service return. However, due to the introduction of S1-Flex and X2 interface, the basic bearer network must have three-layer switching capabilities. Based on the dynamic IP/MPLS protocol and key technologies, the ip ran is a solution t

Intelligent Design of Automatically Switched Optical Network Based on GMPLS

1 Introduction Automatically Switched Optical Network (ASON) is a new type of network that can automatically connect to the network. It consists of three planes: control plane, transfer plane, and management plane. The control plane technology is its core. It can implement dynamic exchange using the control plane. GMPLS generic Multi-Protocol Label Exchange (MSTP) is a common Multi-Protocol Label Exchange Technology proposed by IETF, which is extended by MPL

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.

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

GMPLS Working principle

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

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

Due to the slow convergence of traditional router protocols (IGP in seconds and BGP in minutes), it cannot meet the requirements for carrying real-time services. Network reliability is also an active area in the new technology of man routers. Currently, the new network-layer reliability technologies mainly include fast convergence of IP routes, end-to-end LSP backup,

Differences between hybrid WAN and SD-WAN, wansd-wan differences

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.

Principle of universal Multiprotocol label switching

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
