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

Such as Cisco label exchange TAG Swiching, Ipsilon IP address exchange, and Toshiba Cell Exchange Router CSR: Cell Switching Router) and IBM's ARISAggregate Route based IP Switching), and IETF's Multi-Protocol Label Switching MPLS: Multi-Protocol Label Switching. TAG Switching is a vro

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

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/

Recently, when using Cold Standby tar for Oracle database migration, You need to filter out the files exported by datapump under the current database file, otherwise, a large tar file will be generated and the network transmission time will be consumed. In fact, the tar command provides a filtering function, but many people do not know it because the filtering function is usually used less. This article describes how to filter unwanted files or folders under the tar command. 1. Demo Environment

another, while the route table describes the network information and directs the data packet from one machine to another. 4. misunderstandings At present, many people understand the implementation of a system. These people are similar to three categories. The first type is proficient in Linux kernel, the second type is proficient in the configuration of Cisco devices, and the third type is proficient in Windows Network Programming and NDIS. The three types have very few common intersections, so

As a new network architecture, SDN has become a hot topic in the industry. The open network it advocates represents a change in the concept of network construction from adapting network capabilities to actively adapting network capabilities to the needs of network applications. Separation of forwarding and control, centralized control, and open network programming interfaces are the main features of SDN network architecture. As the main SDN protocol, openflow hopes to use a new forwarding protoc

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 make it very complex and even conflict with each other. In short, the existing layer-4 network structure cannot meet the needs of data business development, and new technical means must be developed.Figu
