a very important application, which will prompt the IT team to rethink the Network Design of San Jose headquarters. Network convergence-transmitting data and voice over the same network-will save Cisco's long-term expenditure and serve as a platform for future development. However, in the short term, it will put heavy pressure on a diverse platform that forms the Cisco network infrastructure. Cisco Catalyst 6500 switch and Gigabit Ethernet The soluti

The previous articles introduced the spark SQL Catalyst Sqlparser, and analyzer, originally intended to write optimizer directly, but found forgetting to introduce TreeNode, the core concept of catalyst, This article explains how to better understand how optimizer is generating optimized Logical plan for optimizing analyzed Logical plan, which is explained by the TreeNode infrastructure.First, TreeNode type

Catalyst Optimizer, catalystoptimizer For more information, see ChenZhongPu's Gitbook:Https://www.gitbook.com/book/chenzhongpu/bigdatanotes/details The Catalyst of Spark SQL is easy to expand. It also supports rule-based and cost-based optimization methods. Inside it, Catalyst contains a common library that represents the tree and operation tree rules. Under thi

The following describes a unique solution on the Cisco Catalyst Switch to prevent the harm of the worm in a very economical, effective, and scalable way, this greatly saves a lot of company losses. What makes the administrators of many service operators and Enterprise Networks A headache is not only the constant development and variants, but also the increasing damage caused by attacks. Although worms do not usually destroy any data, the direct and in

Through significant improvements to the software infrastructure, the Cisco IOS software modular Catalyst 6500 maximizes operational efficiency and reduces downtime. By running the modular Cisco IOS subsystem as an independently recoverable process, this innovation can: Through Fault suppression and stateful process restart, the unplanned downtime can be minimized to improve the availability of integrated applications; By upgrading ISSU through soft

Fast Ethernet and Gigabit Ethernet line cards The Cisco Catalyst 4500 series scalable, modular, and high-density switches provide second, third, and fourth-layer switches and intelligent services with outstanding performance, enabling network control and permanent deployment. These switches provide a variety of Fast Ethernet and Gigabit Ethernet line cards, including desktops, branch backbone and servers for enterprise and commercial exchange solution

AMD (ATI) today released the 9.6 version of the Linux Catalyst Driver, with two functional improvements: support for the new version of the Linux release version (SLED, SLED 11, RHEL 4.8) and enhanced support for MultiView (Multi-head output technology ). The MultiView feature makes full use of multiple GPUs and allows you to set, manage, and use Multiview configurations. A typical application is to build a multi-screen workstation. As early as 8.8 dr

Preparing the Catalyst 4500 switch for CNAThe switch restores the factory default restore command Switch>enable Switch#erase Startup-configSwitch#reload To enable the switch to be managed by CNA, you must have the following two conditions: the IP address of the network management.Configuring IP for G1/1 ports Switch#configureSwitch (config) #interface gigabitethernet 1/1Switch (config-if) #no SwitchportSwitch (config-if) #ip

Fast Ethernet and Gigabit Ethernet line cards The Cisco Catalyst 4500 series scalable, modular, and high-density switches provide superior combined second-layer switching and intelligent services, which enable network control and sustainability. These switches provide a wide range of Fast Ethernet and Gigabit Ethernet line cards, including the desktop, branch backbone and servers for enterprise and commercial Exchange solutions, and the fiber and cop

Recently, big data-related technologies and traditional database technology are a lot of integration and mutual reference. The traditional database strength lies in its proven SQL optimizer experience, the weakness lies in the distributed field of high availability, fault tolerance, scalability, and so on, in time, let it undergo a certain transformation, such as the introduction of Paxos, raft, etc., to strengthen their ability in the distributed domain, I believe we will have a place in the bi

Step 1: Download Native IOS software for Catalyst 6509 from CCO Based on the flash card capacity; Show slot0: shows the flash card capacity. The selected software size should be smaller than or equal to the flash card capacity. If flash card capacity is 24 M, we choose the IOS software c6sup22-psv-mz.121-8b.E15 for Catalyst 6509, which is used for S2 and MSFC2, feature software for service providers, versio

Ethernet switches are still commonly used. So I studied the comprehensive performance of the Catalyst 2950 remote Ethernet switch. I would like to share with you here, hoping to help you. Cisco's long-distance Ethernet switch can leverage existing copper infrastructure to meet high-bandwidth application requirements. Catalyst 2950 long-distance Ethernet LRE) series Ethernet switches Enable Enterprise and se
