MPLS is a connection-oriented transmission technology that can provide effective QoS Assurance; MPLS is a link layer-independent technology that supports X.25, frame relay, ATM, DWDM ......, Multi-network interconnection is ensured. MPLS supports a lar

total number of Route tables, the query speed of the router is greatly improved, and the Memory and CPU requirements of the router are also reduced. This function is completed by the flag router. Because of the CIDR function, the total number of LVC instances required for the flag switch is greatly reduced. Support for IPCoS (ClassofService): MPLS provides interworking with the Class of Service (IP CoS), e

This document mainly explains the following: MPLS header structure and the role of each primary field. How the tagged message is forwarded Keep the MPLS tag names, as well as their role. Determines the importance of MPLS MTU in MPLS networks. In MPLS, they are exchanged

Introduction to the use of the Math. cos () cosine method in JavaScript, javascriptmath. cos This method returns the cosine of a number. The cosine method returns the value between-1 and 1, which indicates the cosine of the angle.Syntax Math.cos( x ) ; The following is the detailed information about the parameters: X: a number. Return Value: Returns the cosine of a number.Example: This produces the fol

Rd and RT (mpls vpn bgp) Rd (route-distinguisher) is used to identify different VPN instances on the PE device. Its main function is to achieve address multiplexing between VPN instances. It and the IP address constitute a 12byte vpnv4 address space, rd and the route are carried together in the bgp update message and published to the peer end. On the one hand, we need to verify whether the RD function is implemented, whether the PE device can achieve

devices can be routers, layer-3 switches, or layer-2 switches. They can be interconnected through different PE devices or the same PE device; only the PE in the backbone network will "perceive" the VPN. The core layer P device does not care about the VPN and is only responsible for label forwarding. Therefore, this configuration method is simple and scalable for carriers. As the PE device of the carrier, S8016 can maintain separate route tables and forwarding tables for different VPN users, whi

Data grouping header based on the needs of various applications, that is, set the priority for the Data Group. The management of network data is completed by users. Diff-Serv is only a protocol used to prioritize data. Based on the user's network, IP groups with different priorities are encapsulated into frame relay or ATM cells and transmitted over the user's network. Data passes through the user's network and arrives at the entry switch, where frame relay or ATM cells are unblocked as downstr

-Protocol Label conversion technology. It has the advantages of layer-2 packet forwarding and layer-3 route selection, the aim is to solve many problems of the group forwarding technology used in the current network environment. The essence of MPLS is that when an IP packet enters the MPLS network, it is assigned a short, fixed-length, locally meaningful label that can distinguish it from other information

To solve the problems faced by the Internet-based IP backbone network, the IETF proposed Multi-Protocol Label Switching (MPLS ). MPLS can greatly improve IP Forwarding performance on the backbone network, and provide service classification (CoS) and QoS Assurance. MPLS can be used on a considerable number of existing t

Mobile data is one of the most promising Telecom businesses. It can meet the needs of various mobile terminal users to access the Internet anytime, anywhere, it can also meet the needs of data and multimedia communication between them. Mobile IP is one of the key technologies to implement mobile data services. It supports mobile terminals with fixed IP addresses to move freely on the Internet and keep communication uninterrupted during the mobile process. Multi-Protocol Label Switching (

With the development of IC card from a simple synchronous card to an asynchronous card, from a simple EPROM card to the internal microprocessor-based smart card (also known as CPU card), the requirements of the IC card is more and more high. The management of the card itself is more and more complex, so there is an urgent need to have a tool to solve this contradiction, and the emergence of the internal microprocessor-enabled smart card, so that the realization of this tool has become a reality.

MPLSMultiprotocol Label Switch (MPLSMultiprotocol Label Switch) was originally proposed to speed up router forwarding, but because MPLS is used in Traffic engineering Traffic Engeering) and VPN are two key technologies in the current IP network. MPLS has become an important standard for expanding the IP network scale. The key to MPLS protocol is to introduce the
