The project uses the current limit, limited by some of the implementation of the way things, the hand tore a simple service-end current limiter.The difference between end-of-stream and client-side throttling is simply:1) service-side limit flowLimit the number of requests in a unit of time, in order to gain high availability through compromise.For example, our scenario is that there is a service receiving a request, after processing, the data bulk to Elasticsearch for index storage, the bulk ind

First, the recursive equationAccording to the idea of divide and conquer, a recursive complexity can be written as a recursive equation.First, the solution of the recursive equation--guess and then proveThis method is also referred to as the surrogate method, the steps are as follows:1, the form of the Guess solution2. Mathematical inductive method proves correctExample:We assume that there is a recursive formula like this:We guess that the solution is T (n) =o (NLGN), and then the recursive sub

Many may not have a special understanding of GE L3 switches. Here we will mainly introduce the future development direction of GE L3 switches. Now, the Internet industry is no stranger to the term "Gigabit Layer 3 Switch". In the construction of medium and large scale networks, mainstream network models with gigabit Layer 3 switch as the core are numerous. As a matter of fact, the emergence of GE

Http://assafmuller.com/2014/08/16/layer-3-high-availability/Low-reliability solution for L3 agents Currently, you can achieve Load Balancing through multiple network nodes, but this is not a highly reliable and redundant solution. Assume that you have three network nodes and create new routes. The routes are automatically planned and distributed on these three network nodes. However, if a node breaks down, all routes will not be able to provide servic

The application and development of L2/L3 Exchange is very active in the field of telecommunication and network technology. According to OSI layering, L2 corresponds to the data link layer, L3 corresponding network layer. In this paper, the second layer of Ethernet protocol and the corresponding third layer of IP protocol Exchange and routing technology are discussed. Application and development of L2 Excha

the advanced features of virus protection and security monitoring.Therefore, in the future switch market, applications of L2 and above Gigabit smart network management switches will become a hot topic.Proposal of a distributed L3 NetworkTo meet the needs of the education industry in terms of network speed, network management, and network applications, a distributed three-layer network architecture is proposed, which consists of three-layer switches t

The Juno version of L3 Ha employs the Keepalived tool, which implements the VRRP protocol internally. First to introduce the following VRRP:VRRP IntroductionVRRP is a routing fault-tolerant protocol, or it can be called a backup routing protocol. All hosts in a local area network set the default route, and when the destination address of the network host is not in this segment, the message will be sent to the external router through the default route,

See a lot of people discuss the 4006 L3 issue, everyone wants to figure out the structure of the x4232-L3The WS-X4232-L3 is a routing module for Cisco Catalyst 4000 series switches and can only be used on a 4000 Switch that uses the Supervisor Engine 1 and 2, the module has 32 Fast Ethernet ports and two 1-gigabit Ethernet ports, and two 1-gigabit Ethernet ports are used as routing interfaces. The module ha

More and more Wan solutions are now using Ethernet overSDH. On the surface, L3 switches and traditional routers can meet the needs of Wan interconnection. Therefore, many partners and customers have this question, what is the difference between the two in the wide area network connection? The following are some of my opinions for your reference.What is the difference between using a Cisco L3 switch and usin

There are many things worth learning about layer-3 switches. Here we mainly introduce the performance of mainstream products, the popularity of networks, and the development of enterprises, which make the traditional exchange system more and more overwhelmed, the enterprise's network environment is also subject to certain restrictions. How can we effectively protect the enterprise's network security measures so that enterprise information can be effectively protected against viruses and maliciou

l3-009. Great Wall time limit MS Memory limit 65536 KB code length limit 8000 B procedure StandardAuthor Deng JunhuiAs we all know, the ancient Great Wall of China was built to resist the invasion of the enemy. On the Great Wall, many beacons were built. Each beacon is monitored for a specific area. Once a region has a foreign invasion, the soldiers on the corresponding Beacon will notify the enemy to the surrounding beacon, and quickly relay to the h

Basic configurations of L3 SwitchesL3 switches play an important role in the replacement of common L2 switches in large and medium-sized networks. The reason is very simple. When there are a large number of computers in the network, it is necessary to divide them into several virtual networks to improve network security and reduce the consumption of network bandwidth by broadcast, this improves network transmission efficiency and computer performance.

, the host a, B, or C may belong to different subnets, they can also directly know the MAC address of the other party for communication. The most important thing is that layer-3 switches do not spread broadcast packets like other switches, A layer-3 switch is called a layer-3 switch because it can understand layer-3 information, such as IP addresses and ARP. Therefore, a layer-3 switch can understand the purpose of a broadcast packet without spreading it out, it also satisfies the needs of the p

L3 instance -- add information I already have a certain understanding and knowledge of the layer-3 basic knowledge, but we still need to practice it to be used flexibly. We can understand it more thoroughly only after the hands-on implementation. First, we need to create a data table. Take my example to create an Users table and add fields such as UserName, Password, and Email. Then start to operate on VS. First, create some basic projects, as shown i

Layer-3 switches are quite common, So I studied the market trend of layer-3 switches and shared them with you here. I hope they will be useful to you. It can be said that all core backbone networks must use layer-3 switches. From a medium-sized campus network to an enterprise's backbone network, metropolitan area network backbone, and aggregation layer are all three-layer switches. If an enterprise does not require a carrier to provide policies, such as taking different billing policies for diff
