1. With the advances in hardware technology and the creation of high-speed routers and three-layer switches, MPLS has had little meaning to increase the speed of forwarding. However, MPLS has been widely used in virtual private network, traffic engineering, QoS and so on because of its support of tag stack and connection-oriented characteristics. MPLS Label switc

The previous document has already learned the information dissemination through OSPF, also introduced the CSPF and path's establishment RSVP work principle. What should we do next? You can forward customer data traffic along the tunnel interface in three ways: Static routing routes Policy Routing Policy Routing Automatic routing Autoroute So to be more blunt, this piece of content is the final phase of Te Tunnel, the key to the key. Just imagine, through arduous, established a te tunnel, b

In March 1999, the Internet Task Force (IETF) published a RFC2547 by Cisco, describing a way for operators to provide virtual private network (VPN) services to users through an IP backbone network. This method uses an extended BGP (Boundary routing protocol) to distribute VPN routing information through the carrier backbone network, and uses Multiprotocol token switching (MPLS) to forward VPN traffic between the VPN user sites. The main purpose of thi

Absrtact: Broadband IP metropolitan Area network, routing planning and design is the core link. In the beginning of the network, must be integrated planning. According to the construction of the metropolitan area Network, the routing strategy based on Bgp/mpls VPN is adopted, which is proved to be feasible by practice.

In the traffic engineering of MPLS TE, it is divided into the following aspects: 1, the release of information 2, the calculation and establishment of the path 3, traffic forwarding in the tunnel. So here to understand the path calculation and build, first of all to understand how SPF is working, and then see what is CSPF (constrained SPF). In order to establish the calculation of the path is a good understanding. In detail, why do you want to lea

of the right-angled triangle and returns the angle in radians. This ratio is the angle of the side length divided by the angle of the adjacent side length of the quotient. The range of values is between-PI/2 and PI/2 radians. To convert the angle to radians, multiply the angle by pi/180. To convert radians to angles, multiply radians by 180/pi. Note: ATN is the inverse trigonometric functions of tan, and the value of tan is the angle, which returns the ratio of two sides of the right-angled tr

Strictly speaking, cos and ToS are only a tag mechanism of QoS.The QoS range is too large, involving the marking and classification of the incoming data stream and the speed limit, the congestion avoidance and management of the network backbone, and the queue scheduling mechanism at the network egress.Cos indicates the priority of L2 isl or 802.1Q data frames. The value ranges from 0 to 7;TOS is the service type tag of layer-3 data packets, which is a

Before learning MPLS, you should know that MPLS has two modes of operation. 1, Frame mode--gt; in the third-level group header (such as IP packet header) before the tag to forward. 2.---gt; in the MPLS network composed of ATM LSR, MPLS is used to exchange Vpi/vci information in the control plane instead of using ATM

In the HUB-AND-SPOKE environment of mpls vpn, for the sake of security AND cost, the branches are not interconnected, AND the access between the branches must go through the firewall of the headquarters, both the security effect and the cost are saved.The experiment topology is as follows:Due to the existence of the downstream bits and domain tags in the anti-ring mechanism of OSPF, the route may not be received in the outbound VRF of r6. therefore, t

MPLS (Multi-propocol Label Switching) is a Multi-Protocol Label exchange.MPLS is a third-generation network architecture and a new generation of IP High-Speed Backbone Network Exchange Standard, proposed by IETF (Internet Engineering Task Force, Internet Engineering Task Group, led by Cisco, ascend, 3Com, and other network equipment manufacturers.MPLS is an integrated IP over ATM technology. It combines routing functions on Frame Relay and ATM switch,
