Remember the experiment of sunlight through a prism? The white light passes through the prism and is decomposed into a variety of colors that gradually transition to the color spectrum, followed by red, orange, yellow, green, green, blue, purple, and this is the visible spectrum. It is clear that the prism separates the mixed things. Today's wireless network is like a bunch of white light, users do not seem to feel the difference at the end, but if the white light through the prism to decompose

1. Preface: When the number of hosts in the production environment reaches a certain scale, how to manage them securely requires special attention. Generally, the Secure Gateway product is used before the office environment or the Internet reaches the production environment. I have been using CheckPoint and Juniper for nearly 10 years. The related enterprise-level products of these two brands have a long history and have comprehensive functions. They

the Chinese market is obviously relatively weak, and it seems to account for about 7% of the world. The high-end products include Juniper. The following are the two sides of H and H3. Let's see the cn2 share of China Telecom.Cisco's 60% market is in North America, while North America is the most closed. Not only Huawei, but ZTE cannot get in, that is, Ericsson and Alcatel are also struggling. Specifically, Moto, Nortel and the merged Lucent are playi

all installed into the RAM in a single boot, generally speaking, the router program is not small (a few megabytes to a few 10 trillion) ; (Note: This is primarily a control plane program, which is the routing engine for Cisco and Juniper)(2) used to store dynamic data such as routing tables, OSPF link state databases, and so on. If a router needs to support up to 100,000 routes and 256 bytes per route, then approximately 200M of memory is required.(3

While transitioning to IPV6, Boko is also deploying load balancers, providing IPV6 translations to public services and retaining IPV4 connections in the internal network. So far, the majority of clients applying for IPV6 services are from education and government departments, especially university research laboratories and government agenci

However, it was recently discovered that a subsidiary of China Unicom can only establish a VPN with the China Telecom line of the company. As we all know, the communication between China Telecom and China Unicom is not very good, so the VPN delay established in this method is very large, and the maximum latency detected can reach 200 ms.Troubl

, we like this method very much, because after risk and vulnerability analysis is introduced, we can create a unified network topology with best practices for analyzing and fixing solutions. We installed Red Seal software on a Dell server running Windows XP. Once the server is installed and started, the client is installed immediately. After logging on using the client application, we can access a fully functional GUI console server. Both the network consultant and vulnerability consultant must
