Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The networks and services of the Internet have been explosively increased, and higher requirements are put forward for backbone networks, and MPLS (Multi Protocol Label switching ) is a technology generated under the background, and absorbs the VPI/VCI switching thought of ATM, seamlessly integrates the flexibility of IP routing technology and the simplicity of two-layer switching, and adds the connection-oriented attribute of MPLS in the connectionless-oriented IP network.
Meanwhile, the advantages of MPLS in traffic engineering, VPN and the like are highlighted. The MPLS VPN is an IP VPN based on MPLS technology, and is an IP virtual private network (IP VPN) which is realized by applying the MPLS technology on network routing and switching equipment, simplifying the routing mode of a core router and combining label switching of the traditional routing technology. MPLS has the advantage of combining two-layer switching and three-layer routing technologies with superior performance in addressing the significant problems of IP networks, such as VPN, service classification and traffic engineering. Therefore, MPLS VPN is also being seen by operators to solve the problem of interconnection between enterprises and provide various new services, and becomes an important means for providing value-added services for IP network operators. MPLS VPNs may be further divided into two-layer MPLS VPNs (i.e., MPLS L2 VPNs) and three-layer MPLS VPNs (i.e., MPLS L3 VPNs). The VPN network structure is shown in fig. 7 and 8.
The MPLS VPN network mainly comprises 3 parts such as CE, PE and P:
ce (customer Edge router) customer network Edge router devices, directly connected to the service provider network, that "sense" the absence of VPNs;
PE (provider Edge router) service provider Edge router equipment which is directly connected with a CE of a user and is responsible for VPN service access and VPN-IPv4 routing processing is a main implementer of MPLS three-layer VPN;
the p (provider router) service provider core router device is responsible for fast forwarding data and is not directly connected with the CE.
In the entire MPLS VPN, P, PE devices need to support the basic functionality of MPLS, and CE devices do not need to support MPLS.
The MPLS VPN network adopts label exchange, one label corresponds to one user data flow, so that the data isolation among users is very easy, the QoS/CoS problem disturbing the traditional IP network can be easily solved by utilizing a differentiated service system, the MPLS self provides the capacity of flow engineering, the network resources can be optimized and configured to the maximum extent, the network fault can be automatically and rapidly repaired, and the high availability and the high reliability are provided.
In order to deploy traffic engineering in a large backbone network, a simple solution with good scalability must be adopted. MPLS TE is proposed for this requirement. TE may also support the currently mainstream MPLS L3/L2VPN application. The TE tunnel can be used as a public network tunnel of VPN application, and bandwidth guarantee is provided for VPN users.
For MPLS forwarding, after an LSP is established, traffic is forwarded through the LSP at an ingress node of the LSP according to an allocated label. The device has different label attributes at different locations in the network to determine which level of label to forward.
The MPLS VPN application comprises L3/L2VPN, PE equipment has different message encapsulation formats and different forwarding behaviors, so that the attributes of labels need to be distinguished; meanwhile, the data stream may be carried in different tunnels, so that it is also necessary to determine the attribute of the label to determine whether the tunnel is terminated, so as to determine which level of label to forward.
