In this high-speed operation of the information age, the use of the cloud to connect work and life is a bit of an ordinary thing. But have you ever asked yourself: Is it really safe to back up your information with the big clouds?It is no exaggeration to say that malicious code and vulnerabilities have long been with you. You don't even have to argue that this is a conspiracy theory, and don't trust you to look at the "User terms" and "privacy policies" of each network. Oh yes, perhaps most peop
This article describes how to control the BT traffic of a Cisco router through specific operations, and describes the specific operation methods in detail. I hope this article will help you.
Network-Based Application Recognition (NBAR) indicates Network Application Recognition. NBAR is a technology that can dynamically search for protocols in Layer 4 to Layer 7. It can not only control static and simple network application protocol TCP/UDP port numbers in general ACLs. For example, the TCP 80 us
How to Use btsync to share files between computers through the network
If you are the kind of person who uses various devices to work online, I believe that you need a method to synchronize files and directories between different devices. At least you are eager to have this function.
BitTorrent Sync (btsync) is a free cross-platform synchronization Tool Based on BitTorrent (the famous P2P file sharing proto
Network-Based Application Recognition (NBAR) indicates Network Application Recognition. NBAR is a technology that can dynamically search for protocols in Layer 4 to Layer 7. It can not only control static and simple network application protocol TCP/UDP port numbers in general ACLs. For example, the TCP 80 used by well-known WEB applications can also control the protocols that generally cannot achieve dynamic ports in ACLs, such as H.323 and SIP used by VoIP.
Suddenly as a night spring breeze, thousand trees million pear blossom. The popularity of BT is more popular than the rivers and lakes, legends and so on. Now we often say the topic is: "Today you BT it?" "Wow k!" Guys, why are you throwing up? If you do not know what BT is, it seems to prove that you have to retire to the Internet, of course, there are more honored to be called "Rookie grade" Shrimp! No, when you finish reading this article, no one will sneer at you, because you will learn to s

Tracker information is primarily the address of the tracker server that is needed in the BT download and the settings for the tracker server. Its main principle is the need to provide the downloaded file virtual into equal size blocks, the block size must be 2k of the whole number of squar

Method 3: load the PDLM Module
Using the PDLM module produced by CISCO saves us the trouble of configuring routing policies and the blocking effect is very good. the two methods described above. one is to block the port used by the data packet, and the other is to block the destination address of the data packet. Although it is valid within a certain range, it cannot completely prohibit BT, this problem exists when you block BT using the PDLM + n bar method.
CISCO provides thre
Module. It is a description of the protocol layer of high-level network applications, such as the protocol type and service port number. Its advantage is to adapt NBAR to many existing network applications, such as http url, DNS, FTP, and VoIP. At the same time, it can also be defined, to enable NBAR to support many emerging network applications. For example, peer2peer tool.PDLM can be downloaded from Cisco websites, and PDLM can be used to limit malicious traffic on some networks. CISCO provid

For website operators and entrepreneurs, the scalability problem is inevitable during the growth of website traffic. How to Establish a scalable architecture) it is an indispensable professional knowledge in the planning of the website business process.
How can we evaluate and analyze the website performance bottleneck when the functionality of the service meets user needs and the
order of the total traffic by default. We can easily see the Host IP address with the highest traffic. Select 10 lines from top to bottom. In this way, we can find the top 10 IP addresses that occupy the most bandwidth in the intranet. (Figure 1) 2. Who is downloading BT? Requirements: BT downloading is an enemy of slow lan network speed. If someone uses BT downloading in the LAN, the speed will be slow.
