With the rise of modern containers comes new problems to solve – especially in networking. Numerous container SDN solutions have recently entered the market, each best suited for a particular environment. Combined with multiple container runtimes and orchestrators available today, there exists a need for a common layer to allow interoperability between them and the network solutions. As different environments demand different networking solutions, multiple vendors and viewpoints look to a specification to help guide interoperability. Container Network Interface (CNI) is a specification started by CoreOS with the input from the wider open source community aimed to make network plugins interoperable between container execution engines. It aims to be as common and vendor-neutral as possible to support a wide variety of networking options — from MACVLAN to modern SDNs such as Weave and flannel. CNI is growing in popularity. It got its start as a network plugin layer for rkt, a container runtime from CoreOS. Today rkt ships with multiple CNI plugins allowing users to take advantage of virtual switching, MACVLAN and IPVLAN as well as multiple IP management strategies, including DHCP. CNI is getting even wider adoption with Kubernetes adding support for it. Kubernetes accelerates development cycles while simplifying operations, and with support for CNI is taking the next step toward a common ground for networking. For continued success toward interoperability, Kubernetes users can come to this session to learn the CNI basics. This talk will cover the CNI interface, including an example of how to build a simple plugin. It will also show Kubernetes users how CNI can be used to solve their networking challenges and how they can get involved. KubeCon schedule link: http://sched.co/4VAo

INFA 620Laboratory 4: Configuring a Firewall In this exercise you will be working with firewalld (see https://www.linode.com/docs/security/firewalls/introduction-to-firewalld-on-centos), a front-end to controlling Iptables. Iptables is a flexible firewall utility built for Linux operating systems (see https://www.howtogeek.com/177621/the-beginners-guide-to-iptables-the-linux-firewall/). It is too low level, however, and, as such, hard to use and configure the rules for filtering traffic. firewalld provides higher-level command line and graphical interfaces over Iptables to ease the pain of configuring the firewall features provided by Linux. For this lab exercise, we will only be using only the high-level command line interface. firewalld provides a dynamically managed firewall with support for network/firewall “zones” to assign a level of trust to a network and its associated connections, interfaces or sources. It has support for IPv4 and IPv6. There is a separation of the runtime and permanent configuration options. For this lab exercise, we will be using two machines, one machine will behave like an Enterprise and the other machine will behave like machines outside an enterprise. We will call this machine as External, external to the enterprise. The firewall, as part of the enterprise will control traffic both coming into the enterprise and going out of the enterprise (to External). NIXENT01 (Enterprise) is a CentOS 7 machine.CentOS is a Linux distribution that attempts to provide a free, enterprise-class, community-supported computing platform. Firewalld will be running on this host. NIXEXT01 (External) is Kali Linux. Kali Linux is a Debian-based Linux distribution aimed at advanced Penetration Testing and Security Auditing. Kali contains several hundred tools which are geared towards various information security tasks, such as Penetration Testing, Security research, Computer Forensics and Reverse Engineering. You have already used this machine for Lab2 and Lab 3 in analyzing packets using Wireshark. (Wireshark is available as part of Kali distribution.) Although there are only two machines, we are going to pretend that the Enterprise has three machines (three IP addresses) and each machine has certain services running on those machines, as follows: NIXENT01 (Enterprise) Service Associated IP Address domain, telnet 192.168.10.10 http, https 192.168.10.20 ftp, imap2, imaps, pop3, pop3s, urd 192.168.10.30 Similarly, we are going to emulate three machines on the External machine with three IP addresses, each running only certain services as follows: NIXEXT01 (External) Service Associated IP Address domain, telnet 192.168.10.210 http, https 192.168.10.220 ftp, imap, imaps, pop3, pop3s, urd 192.168.10.230 The instructions to use the remote UMUC machine in the DaaS environment is provided in the Accessing Remote DaaS Lab under Course Content. Allocating the Lab Machines Once you open the Lab Broker using the instructions given in ...

Clara fears she may have made a mistake in how she handled the expense. She consults her financial planner about the $4,800 refund. The income tax return has not been filed for the year Tim died. How should the financial planner advise Clara? CHOOSE ALL that apply. The year after Tim died, Clara received a refund of $4,800 from the hospital where Tim died. She had paid the hospital $5,600 late in the prior year for the medical bill and planned to add the expense to the rest of the unreimbursed medical expenses from Tim's death. Her son, Vince, told her to allow the estate to reimburse her when she paid the bill, but Clara chose to forego reimbursement. Faced with the check from the hospital, Clara fears she may have made a mistake in how she handled the expense. She consults her financial planner about the $4,800 refund. The income tax return has not been filed for the year Tim died. How should the financial planner advise Clara? CHOOSE ALL that apply. Clara should add $5600 in income to her tax return the year after Tim died Clara should add $800 of the hospital bill to any other unreimbursed medical expenses she has and use the expenses to determine whether the total exceeds 10% of the AGI floor for the medical expense deduction for the year Tim died. She may file either as married filing jointly with Tim for 2021 or married filing separately but the election must be coordinated with the estate executor. Clara would be more likely to benefit from the deduction than the estate, which owes no estate taxes. Tim's estate does not face any estate tax liability and does not need a medical deduction. Insurance Information Life Insurance Irrevocable Life Insurance Trust (ILIT) Tim created an ILIT 10 years ago. The only assets in the trust are $200,000 in proceeds from the life insurance policy the ILIT owned at Tim's death. The income beneficiary of the ILIT is Clara. The remainder beneficiaries are the grandchildren. Clara currently receives an annual income of $10,000 based on a return of 5% on the trust assets. Health Insurance Tim and Clara were both covered under Medicare Part A and B until the time of his death. Clara is still covered under Medicare Part A and B..

Case 121 Carson Manor In late November, Ms. Elaine Taylor, director of supply for the city of Winston, was reviewing proposals for the Carson Manor study. Three consulting groups had responded to a request for proposal (RFP) to study the operation of the city-owned nursing home. Ms. Taylor knew that her recommendations for selection of a consultant would have to be completed by mid-December. page 360 CARSON MANOR Carson Manor was opened about 30 years ago for persons requiring nursing care. Carson had a bed capacity of 470. Staff totaled 235 with nonmanagement personnel unionized under the District Service Workers Union Local 325. Day-to-day operations of the Carson Manor were the responsibility of the Carson Manor administrator, who reported to Mr. Henry Davis, the citys director of social services. Policy and budget plans were developed by Mr. Davis and his staff in conjunction with Carson administrative staff and the Carson Manor Committee of Management (CMCM). The CMCM consisted of five aldermen who were appointed or volunteered to fill these positions. The CMCM reported to another aldermanic committee, with broader community service concerns, called the Committee for Community Services. This committee reviewed major expenditures and decisions impacting community service policy. All major expenditures were then reviewed by the Board of Control, consisting of the mayor and four elected controllers, prior to being sent to city council for final approval. As director of social services, Mr. Davis reported to the city administrator, Mr. J. Peterson, who in turn reported to the mayor. The combined elected and appointed reporting structure is shown in Exhibit 1. PURCHASING AND SUPPLY DIVISION (PSD) The PSD had purchasing and disposal authority for the citys engineering, fire, landfill/sanitation departments, and social services division, and for city hall building support. The city operated separate purchasing departments in the public utilities commission, the libraries, and the police department. Purchasing authority was granted to the PSD director and her buyers by municipal bylaw. This bylaw outlined the limits of purchasing authority and formed the basis of the PSDs Policy Manual for Purchasing, Tendering, and Disposal. The main objective of the PSD was to respond to the needs of other departments and divisions for goods and services at minimum cost, consistent with desired quality, delivery timing, and reliability. The PSD had expertise in the purchasing and tendering of goods and certain services, such as equipment rental, maintenance contracts, and engineering/architectural consulting. However, it had not dealt extensively with management consulting service procurement at that time. Elaine Taylor became director of PSD two years ago at the age of 35. Prior to this, she was chief buyer and assistant director of purchasing for the city of Forestview, similar in size to Winston. Elaine reported to the city treasurer, Mr. R. Holbright, and .

CASE STUDY 1 Alternative Water Supply Gordon Rivers, the city manager of Saratoga, Florida, pitched the proposed design schedule back at Jay Andrews. Jay Andrews is the project manager for Major Design Corporation (MDC). The city of Saratoga selected MDC for this project. As a project manager, Jays responsibility is to assemble the technical team necessary to complete the project, develop and track the budget, establish and maintain the schedule, allocate resources as required, and manage the project until completion. We need the intake and transmission main designed, bid, and completed in 35 weeks. The city of Saratoga has a future $2 million dollar federal grant riding on the project getting done on time, Mr. Rivers said. Jay nodded in agreement. Mr. Rivers continued by saying, Jay, the project needs to come in on schedule and within the budget. Now take this schedule back and figure out how we are going to do it. Background Major Design Corporation is a 3,500-employee firm with annual revenues of more than $1 billion. The firm is divided into five geographically based global sales divisions, an engineering/technical services division based in the United States, and a wholly owned construction company. MDC offers full servicesconsulting, engineering, construction, and operationsacross the project life cycle for water, environment, transportation, energy, and facility resources. MDC was selected by the city of Saratoga to design a new, 10-million-gallon-per-day surface water intake and transmission main. The intake withdraws water from a canal and pumps it more than two miles to the citys wastewater treatment plant. There, the canal water is blended with reclaimed water (i.e., treated sewage water) and distributed back to customers for irrigation purposes. This project is touted as an alternative water supply project because the water source is not a historically used source. The project will increase the long-term sustainability of the city because it will diversify the citys water supply portfolio and recycle water. The project will also minimize the need for additional withdrawals from historic water sources, which have become less productive and more highly regulated in the past 10 years, as the citys population continues to grow. Other green benefits of the project include reduced environmental impacts on the historic water sources and a reduced carbon footprint, as the irrigation water requires less energy-intensive treatment than the citys other drinkable water sources. Project Description The objective of the project is to design a fully functional surface water intake that is protective of the environment, will last at least 30 years, and will have a low life-cycle cost (i.e., capital, maintenance, and energy consumption). For this type of project, engineering design accounts for 20 percent of total project cost. The design stage is also important because the decisions made during design lock in 80 percent or more of the life-cycle .

Case 1 Why shareholders wealth maximization /value maximization is considered as better objective of financial management instead of profit maximization and how do we calculate shareholders wealth? In the pre reform era, State Electricity Board in Odisha was incurring huge transmission and distribution (T&D) losses eroding its financial health. State government initiated reforms to transform the state-owned electricity sector into decentralized, market oriented industry with private sector participation. Odisha was the first State in the country to undertake such reform and restructure its power sector in 1996 in order to make power supply more efficient and also to meet the investment needs of the sector. The reforms led to setting up of Odisha Electricity Regulatory Commission (OERC). OERC was the first of its kind in the country to be created in the electricity sector. Post reform, OERC has done pioneering work and has framed regulations as required under Section 185 of the Electricity Act. The Orissa State Electricity Board which was a monolithic organisation, looking after generation, transmission and distribution of power was unbundled. In the reform process, distribution system was entrusted to three private companies. The Distribution Licensee operating in Odisha namely NESCO, WESCO and SOUTHCO are carrying out the business of distribution and retail supply of electricity in their licensed areas. Since the reform, consumer base has doubled. The count of electricity consumers in the state is expected to reach 9.6 million in FY19, from 5.8 million by the end of 2014-15. However, almost half of the households still lack access to the electricity. The growth in electricity demand is slated to be the most in 2015-19, pegged to grow at 9.86 per cent. This is more than double the growth of 4.11 per cent that the state logged during 2010- 15. A report says there is substantial investment in Capital Expenditure (capex). Distribution companies (discoms) in the state have spent Rs.550 crore on Capex programme with an aim to prune high AT&C (aggregate technical & commercial) losses. It would be pertinent to analyse the performance of distribution companies during the regulatory regime relating to important parameters of performance. Following table provides summary of performance. Performance of distribution companies in terms of distribution loss, AT&C loss and collection efficiency DISCOMS Year CESU WESCO NESCO SOUTHCO ALL 1999-00 2011-12 Difference 1999- 00 2011-12 Difference 1999-00 2011-12 Difference 1999-00 2011-12 Difference 1999-00 2011- 12 Difference Distribution Collection Loss (%) Efficiency (%) 69.72 97.14 27.42 83.36 97.13 13.77 79.37 100 20.63 -21.13 78.75 54.2 97.8 47.6 19.05 -6.6 77.19 56.71 98.08 39.73 20.89 - 16.98 44.89 38.3 -6.59 44.17 38.89 -5.28 43.35 34.28 -9.07 41.84 46.42 4.58 43.91 38.55 -5.36 AT&C Loss (%) 61.58 39.97 -21.61 53.46 40.6 -12.86 55.04 33.91 There has been a unique episode in the history of Odisha State pow.

Business Plan A business plan is any simple plan, not only limited to the business start-up plan that helps the management to understand the current situation of the enterprises (strengths, weakness, opportunities and threats) and look forward into the future. A start-up plan is a business plan which consists of the mission, vision, objectives and action plans for the future of the new enterprises while the business plan drawn during the operation of the firm is vital for running the firm effectively, acquire new customers, partners, loans and so on. According to Fiore (2005), a business plan involves two dimensions; an organizing tool to simplify and clarify your business goals and strategy, the second one is a selling document that sells the business idea and shows that a product or a service can make a profit and attract funding and company resources. Imagine you started a new business as an entrepreneur in Saudi Arabia. Briefly mention the specific steps which you consider necessary to a successful business plan. Please, think and share information on the following items: a. Your Business Name, Address, EMail b. Form of ownership: What is the legal structure? Sole proprietor, Partnership, Corporation. C. Investment capital.

Can we draw this BPM on paper showing shapes arrows and connectors? Flow chart is very confusing. Paper-based systems worked for decades, but they were relatively inefficient and prone to error. Why? To understand this, you need a more detailed view of the process: It began with a customer order (usually via phone or fax). An employee at the tug company wrote down the work that needed to be done; that description would then be rewritten and handed to tug captains as a job to do; dispatchers would copy it again onto the dispatch log sheet. When the job was completed, the captains handed their log sheets back to the dispatchers. Dispatchers reviewed the sheets and sent a delivery notice to their customer. The log sheets would then get passed to accounting staff, who rewrote (or retyped) the entire job into an invoice and sent it out. Finally, the accountant would have to re-enter all the invoicing details into the accounting system. Paper-based systems worked for decades, but they were relatively inefficient and prone to error.

Can u give a CORAS ASSEST DIAGRAM for the following case study - The Smart Grid, a pivotal technology underpinning modern energy infrastructure, integrates various communication networks to enhance its efficiency and responsiveness [1]. Predominantly, it comprises three primary networks: the Home Area Network (HAN), Neighbor Area Network (NAN), and Wide Area Network (WAN) [8]. Recent research elucidates the configurations of these networks, especially the HAN [3]. One proposed architecture involves a smart meter directly monitoring household appliances to optimize grid management [5]. A notable limitation of this approach is the requirement for all devices to employ a uniform networking protocol, potentially leading to compatibility issues [4]. To address these concerns, an alternative architecture has been proposed [8]. Here, devices interface with the smart meter through a gateway, which acts as a mediator [6]. This design allows for diverse communication protocols, enhancing system flexibility. Figure 1 shows a simplified model of the Smart Grid communication network, factoring in the gateway mechanism [7]. In this representation, each household mirrors a house in the actual power grid. The model further groups these households into discrete clusters, analogous to the clustering of residences in the real-world grid. Each household in this model incorporates five smart appliances: a smart TV, thermostat, robot vacuum cleaner, light, and an IP camera. The gateway, situated within each household, processes messages from these appliances, selectively forwarding pertinent data to the smart meter. This data then travels to the area concentrator. The model features five such concentrators, each corresponding to distinct areas: A through E. These concentrators relay the information to a central concentrator. Subsequently, the aggregated data converges at the SCADA system, which, for the context of this study, remains outside the scope of discussion [13]. For organizational coherence, every device or node possesses a unique ID, derived from a combination of device type, area, and household number. For instance, a smart TV in the first house of area A would be labeled as TVA1. By extension, other devices in the same household would have labels such as ThermostatA1, CleanerA1, and so forth. The area-specific concentrators are denoted as ConcentratorA to ConcentratorE, and the central entity is labeled as the Central Concentrator. The data flowing through the Smart Grid's communication networks offers manifold utilities [4]. Utility companies can leverage this data for demand forecasting, ensuring grid reliability, and fostering efficient energy distribution [6]. Moreover, the data can inform dynamic pricing models, facilitate remote grid monitoring, and enhance customer service [9]. Additionally, the data can guide infrastructure development, bolster security measures, and aid in the integration of renewable energy sources [7]. Ensuring the confident.

BUsiness law 9.3 Implied-in-Fact Contract For six years, Lee Marvin, an actor, lived with Michelle Marvin. They were not married. At the end of six years, Lee Marvin compelled Michelle Marvin to leave his household. He continued to support her for another year but thereafter refused to provide further support. During their time together, Lee Marvin earned substantial income and acquired property, including motion-picture rights worth more than $1 million. Michelle Marvin brought an action against Lee Marvin, alleging that an implied-in-fact contract existed between them and that she was enti-tled to half of the property that they had acquired while living together. She claimed that she had given up a lucrative career as an entertainer and singer to be a full-time companion, homemaker, housekeeper, and cook. Marvin v. Marvin, 18 Cal.3d 660, 557 P.2d 106, 134 Cal.Rptr. 815, Web 1976 Cal. Lexis 377 (Supreme Court of California) question Dont get hung up on the value. First prove there was a contract then the value can be debated later. There are three things that must happen to have an implied in fact contract. Did these things happen?.
