the original technologies, protecting existing investment and network resources, MPLS can provide connection-oriented services in a connectionless or explicit routing mode, which makes MPLS suitable for dynamic tunneling technology, it also guarantees the QoS requirements of data transmission services. tunnel technology is currently an effective means to support VPN services. QoS is the basis for realizing

Mobile MPLS and Its Key Technologies

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 proc

Application of MPLS Technology

consequences, such as the "N square" problem of virtual circuits. MPLS effectively solves these problems and improves the scalability of ATM. MPLS mainly solves the scalability problems caused by the combination of IP and ATM in the following ways: VC merge: to reduce the number of virtual circuits and reduce system overhead, A VCMerge technology is adopted. It can compress multiple virtual circuits into a

, this results in data leakage.  Therefore, to enable LSR to provide MPLS-based VPN services, you must modify these devices. 3. MPLS-based VPN implementation  3.1 History of VPN  VPN service is a concept that has been proposed for a long time. However, in the past, the telecom provider provided VPN as a covered VPN service on the transmission network.

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

Rd and RT (mpls vpn bgp) RD and RT (mpls vpn bgp)

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

-LDPLabel Dispatch Protocol and Constrain based Routing Label Dispatch Protocol. This is due to the idea of ATM networks. CR-LDP and LDP are the same protocol, and CR-LDP is an extension of LDP, which uses the same messages and mechanisms as LDP, such as peering discovery, session creation and persistence, tag publishing, and error handling. The other type is RSVP, which is based on the traditional IP routing protocol. RSVP and LDP/CR-LDP are two different protocols, they have different protocol

protocol, once the link fails and then resumes, SPF recalculates all the topologies in the zone and synchronizes it to each router, during which time the synchronization topology makes the device a lot worse, and the CPU utilization runs to 80%. The topology stabilizes to normal forwarding, This is only IGP, and this problem is even more serious in Mpls te, because after IGP is stable, LDP or RSVP can work, build up and then distribute tags to create

I won't talk about the configuration. Read the previous blog!1. propagation of CE and pe vrf private networksThe IPV4 route in the CE global route table is transmitted to the corresponding VRF route table of PE through the routing protocol (such as RIP, OSPF, OSPF, and BGP) between PE-CE. On PE, the routing protocol (Routing Protocol process or routing protocol instance) for routing exchange with CE must be bound to the corresponding VRF. On the bound VRF interface, only the VRF routing protocol
