function, it will also have the function of Automatically dividing the data stream level and service level, as well as providing some form of QoS, etc, this will be another important feature of layer-3 switches. Since the middle of 1990s, the world's major companies have studied the third-tier exchange and proposed many different solutions and launched many products. Such as Cisco label exchange TAG Swiching, Ipsilon IP address exchange, and Toshiba Cell Exchange Router CSR: Cell Switching Rout

forwarding for different queues based on predefined or user-specified priorities.Routers usually use RED Early Detection and WRED weighted early detection in the queue to avoid congestion.MPLS Technology As an efficient IP backbone network technology platform, MPLS technology provides a flexible and scalable backbone network exchange technology for the next generation of IP networks. Using MPLS technology

VPN technology-P, PE, CE what is P, PE, cempls vpn there are three types of routers, CE router, PE router and P router. The CE router is a client router that provides you with a connection to the PE router. The PE router is the operator's edge router, that is, the Label Edge Router (LER) in the MPLS network ), it processes the VPN data from the CE router or the label exchange path (LSP) based on the stored route information and forwards the data. It i

1 Introduction With the rapid development of Internet and optical fiber technology, the integration of IP and Optical network technology will become an important trend of network development in the future. How to solve the integration of IP layer and optical layer, GMPLS provides a good idea. Gmpls inherits almost all MPLS features and protocols, and is an extension of MPLS to optical network, it can use u

Multi-Protocol label switching (MPLS) In traditional 3-tier forwarding, each router extracts forwarding information from a 3-tier file header as packets are transmitted over the network. This file header analysis is repeated for each router that the packet passes through. In MPLS networks, packets are forwarded according to the label. Each IP network that can be reached through an interface is assigned a

In the previous compilation of MPLS into the Linux kernel, it is now necessary to install Iprouter, the installation process is as follows:1) Download two files of iproute2-2.6.39.tar.gz and Iproute2-v2.6.39-mpls.patch.Iproute2-2.6.39.tar.gz:http://pkgs.fedoraproject.org/repo/pkgs/iproute/iproute2-2.6.39.tar.gz/8a3b6bc77c2ecf752284aa4a6fc630a6/ Iproute2-2.6.39.tar.gzIproute2-v2.6.39-mpls.patch:Http://ftp.jaist.ac.jp/pub/sourceforge/m/project/mp/

PDevice,PEDevice,CEDevice Mpls vpn has three types of routers: CE router, PE router, and P router. (1) The CE router is a client router that provides you with a connection to the PE router. The PE router is the operator's edge router, that is, the Label Edge Router (LER) in the MPLS network ), it processes the VPN data from the CE router or the label exchange path (LSP) based on the stored route information

efficiency is only 75%, which means the efficiency is low. Third, the layer-4 architecture has excessive bandwidth granularity and overlapping functions. Layer-4 bandwidth allocation uses four completely different methods, namely, IP packets, ATM cells, SDH frames, and WDM wavelengths. In actual use, there is no need for so many bandwidth particles. In terms of functions, each layer has functions of adjacent layers, especially the protection and recovery functions. Each layer has functions that

unicast communication, it is not suitable for multicast communication. Although the transition technology of multicast communication has not yet become the focus of people's research work, as a very practical application of the research direction, more and more organizations and groups are paying attention to this issue. The evolution from IPv4 to IPv6 is a long-term complex process, so it is impossible to achieve it overnight in the short term, at present, there are two main types of solutions

The evolution from IPv4 to IPv6 is a long-term complex process, so it is impossible to achieve it overnight in the short term, at present, there are two main types of solutions: Pure IP network evolution solution and MPLS network evolution solution.

TCP/IP), etc. The availability of NAT special protocols is related to the device model. Please refer to the actual situation of the device. Nat multi-instance support Nat multi-instance allows users of different MPLS VPNs to access the external network through the same egress, and allows users of different MPLS VPNs to access the external networkVPN users use the same private IP address. When an

, participated by Microsoft and other companies, and has become a standard RFC. L2TP can be used to implement the dialing VPN service or the leased line VPN service. Layer 3 tunnel protocol: user data is encapsulated at Layer 3rd of the network protocol stack. The following tunnel protocols are available:IPSecIP Security) Protocol: the IPSec protocol is not a separate protocol. It provides a complete set of architecture for data Security on the IP network, including AHAuthentication Header), ESP

will think that the two tables must be differentiated. Otherwise, how can MPLS be implemented? Who are familiar with Windows core? Windows is rarely used as a router. 5. Differentiate the benefits of two tables MPLS is an obvious example of distinguishing route tables and forwarding tables. First, it declares that MPLS is a network rather than a node running a
