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
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
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: Pure IP network evolution solution and MPLS network evolution solution.

Gateway) mechanism to support some special application protocols, without any modification to the NAT platform, it has good scalability. The packets of these special protocols carry the address or port information, which may also need to be converted.
Supported special protocols include: FTP (file transfer protocol, file transfer protocol), PPTP (Point-to-Point Tunneling Protocol, point-to-point tunnel protocol), ICMP (Internet Control Message Protocol, internet Control Message Protocol), DNS (
This was discovered by a boy surnamed.Boy surface.This image is similar to a Rome image and is a three-point image. It can be said that it is made of a Rome surface change.
This article will show the generation algorithms and cut diagrams of several boy surfaces, and generate mathematical graphics using script code with custom syntax. for related software, see: Mathematical graphics visualization tool. This software is free and open-source. QQ chat group: 367752815

The current network construction has been developed from the original regional network to cross-regional, trans-city wide area Connection, and the security requirements of the network and the increasing carrying business, with the original means of networking many problems difficult to solve. Because of the inherent advantages of MPLS VPN technology, the special network has solved the problems that bother users and integrators. The following is the us

The Peer-to-peer model unifies the control plane of the optical transmission network level and the Service Exchange network level, uses the unified control plane, from the control point of view, they are equal, does not divide the upper and lower level, its addr
The idea of the C program is roughly to clarify, usually not programming, a lot of minor issues, but fortunately accompanied by a mother-in-law, quickly resolved. Draw a 16-point FFT. This is not an optimized program, but it should be the case for a clear idea. The next step is FPGA. Japanese words are not backed up yet. This week is messy, and every week is messy.
Similar to the previous program, the four-point data input is divided into eight equations in the real imaginary part.

First, the cosine theorem is proved:Having an edge of a, B, c, the corresponding angle is a_angle, B _angle, c_angleThe following relationship can be found as a diagonal line from the point to the corresponding edge:(1)A = B * cos c_angle + c * cos B _angle(2)B = a * cos c_angle + c * cos a_angle(3)C = a *

. There are many ways to integrate the IPv6 router service on the carrier's core Backbone Network: IPv6 private network, Dual Stack IPv4-IPv6 router backbone network, or the existing MPLS backbone network can be run on multiple different data link layers. If IPv6 data traffic and generated business income meet the required investment and risks agreed by both parties, users can deploy these solutions on the backbone network. We need a way to build a re
The performance of Huawei enterprise-level routers is still very good, and the market demand is gradually increasing. Here we will introduce the Huawei NetEngine enterprise-level routers to you, quidwayNetEngine 20E/20 series routers are the fifth-generation enterprise-level high-performance Routers developed by Huawei Technology Co., Ltd. for carriers, industry networks, and enterprise networks. NE20E/NE20 series enterprise router according to the number of business slot can be divided into NE2
