VMWare NSX In this next generation data-center infrastructure, there are many vendors who provide network virtualization in datacenter space. Also you aware about that the virtual networks are provisioned and managed independent of the underlying hardware, so here is the solution provided by VMware named as VMware NSX which is a network virtualization solution that allows you to build software-defined networks in virtualized datacenters. VMware NSX is the VMware SDN network virtualization and security platform that emerged from VMware after they acquired Nicira in 2012. This acquisition launched VMware into the software-defined networking (SDN) and network functions virtualization (NFV) world. VMWare NSX NSX software-defined networking (SDN) is part of VMware's software-defined data center (SDDC) concept, which offers cloud computing on VMware virtualization technologies. VMware's stated goal with NSX is to provision virtual networking environments without a command-lin

4G 4 G is a mobile phone network technology, and like its predecessor 3G, it can be used for downloading data and accessing internet, but the difference is that it’s a lot faster than 3G. 5G 5G is the fifth generation of wireless network technology.It is built on what’s called millimeter waves, a section of very high frequency spectrum upwards of 20 GHz all the way up to 96 GHz. 4G Network - 5G Network All about 4G technology 4G stands for Fourth Generation technology The maximum upload rate of 4G technology is 500 Mbps The maximum download rate of 4G technology is 1 Gbps The latency of 4G technology is about 50 ms 4G offers   CDMA 4G can’t differentiate between fixed and mobile devices 4G has the advantages of high speed handoffs, global mobility 4G can be used for high speed applications, mobile TV, wearable devices It is slow and less efficient in comparison of 5G All about 5G technology 5G stands for Fifth Generation technology It provides maximum upload rate

vmstat   command in Linux/Unix is a   performance monitoring command   of the system as it gives the information about processes, memory, paging, block IO, disk and CPU scheduling. All these functionalities makes the command   vmstat   also known as   virtual memory statistic reporter . Syntax : vmstat Delay: It is the time interval in between two updates. It can be termed as a sampling period after each interval of the sampling period report that will be printed with the updated details. If there will be no delay specified only one report will be printed with average value since boot. Count: It is the number of updates which is printed after each interval(sampling period). In absence of count and delay is specified, the default value of count is   infinite . Free: It specifies the amount of free memory/idle memory spaces which are not being used. si: Memory that is swapped in every second from disk in kilobytes. so: Memory that is swapped out every second to disk in kiloby

VRF lite is one types of wait wait before start understainding of VRF lite you guys should be aware of PE as well as CE Router. in MPLS networks related scenario the PE router is the Provider's edge router and the CE is the Customer edge router where the routing or L2 protocol works. The MPLS works start between one end PE to other end PE routers. What is VRF lite? VRFs as VPN Routing and Forwarding instances, are most commonly associated with MPLS service providers. In such networks, MPLS encapsulation is used to isolate individual customers' traffic and an independent routing table (VRF) is maintained for each customer. Mostly the MP-BGP is employed to facilitate complex redistribution schemes to import and export routes to and from VRFs to provide Internet connectivity. VRF-lite is a feature in MPLS environment that enables a service provider to support two or more VPNs, where IP addresses can be overlapped among the VPNs. VRF-lite uses input interfaces to distinguish r

Route Target is one of the extensive community of BGP which is used in MPLS networks. Before understading and knowing about the what is the Route Target?, you have to know some basic concepts as VRF, RD which is generally used in MPLS network. VRF ( Virtual route forwarding ) we discussed earlier in the post, Now the important term to understand is RT ( Route Target ) Used with RD and VRF.  MPLS Route Target First of all we are going to know about why RT (Route Target) used in MPLS networks, RT ( Route Target ) comes into the scene when you have multiple remote sites which is connected to MPLS. So there are two concepts of RT as an Import and export. How and where to use Import and Export RT. as with any VRF, When you configure RT import, it imports all the prefixes that matches the configured RT value as one of the attribute in the BGP update. So in any-any VRF, it is common to see all PE configured with same RT value (You may see more RT depending on inter-VRF scenarios). Al

What is MPLS? Multiprotocol Label Switching (MPLS) is data forwarding technology that increases the speed and controls the flow of network traffic. With MPLS, data is directed through a path via labels instead of requiring complex lookups in a routing table at every stop. MPLS Network Scalable and protocol independent, this technique works with Internet Protocol (IP) and Asynchronous Transport Mode (ATM). MPLS allows most data packets to be forwarded at Layer 2 -- the switching level -- of the Open Systems Interconnection (OSI) model, rather than having to be passed up to Layer 3 -- the routing level. For this reason, it is often informally described as operating at Layer 2.5 In an MPLS network, the first router to receive a packet determines the packet's entire route upfront, the identity of which is quickly conveyed to subsequent routers using a label in the packet header. While router hardware has improved exponentially since MPLS was first developed -- somewhat diminishi

You guys already knows about ants and aware of the things as they can do it like they can get in anywhere, because of their tiny size. Ants don’t usually cause a lot of problems unless you landed yourself in an ant infestation. If you did, then you need to prepare because they can damage your things. The best way to know where ants are is to follow their trail, and they’ll lead you to its nest. Here are some ways an ant infestation can ruin your network. Did Ants Ruin your Network? Unstable Network Connection All users are not happy with having and unstable network connection,and who would be especially if you’re paying a lot? There are several reasons why your network connection is unstable, and the last thing you’d want it to is because of an ant infestation. Ants can gnaw through anything, especially if there are a lot of them gnawing on the same kind. Ants are highly persistent, so they’ll get the job done. If your cables are located on the floor or in reachable areas, there
