WIRELESS NETWORK METHOD USING IN SMART GRID COMMUNICATIONS Ehsan Dolatshahi Independent Study April 22, 2015 Introduction The old generation of electrical power grid has taken care of our needs in the past. However, as our world progress technologically, so do the expectations from different infrastructures around us. Smart grid is an initiative to completely restructure the electrical power grid to meet the current and future requirements of its clients. Upgrading our electrical power grid

Network bandwidth demand is growing by 35%. Storage capacity is growing by 50%. Power costs growth is 20%. Throwing more capacity at demand is not the solution; there is a need to optimize capacity in new ways. Over 1.5 billion Web pages are accessible, 450

that can connect 2 local area networks (LAN). A bridge can learn all of the MAC addresses on the network, and this is done during the bridges data gathering phase. Basically a bridge will receive the data and analyze the address. The bridge will then pass the data on to the correct address. The ports on a bridge are in and out, but they are smart ports with the ability to locate the address on the network. Switches are much like a bridge where they can connect networks that use the same

Virtual Private Network. It provides a private network across the public network (Internet). This allows the user to transmit and receive data to the private network across Internet, like it is being directly connected to it. VPN has the characteristics of point-to-point and private link. To resemble a point-to-point link, the data is sent along with the routing information necessary to reach the destination through the public network. Data is encrypted and only the users in the network can access the

a decrease in the organization’s revenue; client’s personal information being accessed, modified, or even deleted; and even degraded network performance. QWD would lose significant clientele and would not be as appealing to their target audience – not so good for their mission of providing top quality services. Policy Reducing the exposure of the corporate network from outside attacks is crucial in protecting mission-critical processes for QWD. The security assessment doesn’t end with software

The Pacific JWICS ESC’s Use of the Internet Even though the Pacific JWICS ESC operates on a private network, many of its working force require the use of the public internet to meet service requirements. Air Force policy dictates specific purchases through commercial websites. Troubleshooting and service support from vendors usually begin with their respective websites as well. Besides direct vendor issues, every Pacific ESC member must utilize the internet to meet requirements or take administrative

1. Case Study It’s a project on WAN network design for a company which is five year old and have multiple branches. It’s a IT& Electronics company located in Auckland named eServe. I am working for this company from last six months as a IT technician. The company have multiple branches in other cities as well. They provide software and hardware related services to their clients and mainly concern with apple (Mac Book, iMac, phone) products. The company have three branches in wellington, Christchurch

Network analysis In 1991 Dr. Riordan created Riordan Manufacturing which is a Company that produces all kind of plastics. Riordan currently has a location in Hangzhou China and is moving that location to Shanghai China. In this analysis I will cover communication protocols and their importance, rationale for design protocols, overall network architecture, how a traffic analysis is used, jitter, response time, and latency, along with their effect on a network. Also discussed is data rates and their
