Introduction
BGP: The Border Gateway Protocol (BGP) is the protocol used throughout the Internet to exchange routing information between networks. It is the language spoken by routers on the Internet to determine how packets can be sent from one router to another to reach their final destination. BGP has worked extremely well and continues to be protocol that makes the Internet work.

1989-01-01 Started group
Current version
The current version of BGP is version 4 (BGP4) codified in RFC 4271 since 2006. Early versions of the protocol are widely considered obsolete and are rarely supported. RFC 4271, which went through more than 20 drafts, is based on the earlier RFC 1771 version 4. The RFC 4271 version corrected a number of errors, clarified ambiguities and brought the RFC much closer to industry practices. Version 4 of BGP has been in use on the Internet since 1994. The major enhancement in version 4 was support for Classless Inter-Domain Routing and use of route aggregation to decrease the size of routing.
Uses
Most Internet service providers must use BGP to establish routing between one another (especially if they are multihomed). Compare this with Signaling System 7(SS7), which is the inter-provider core call setup protocol on the PSTN.
Very large private IP networks use BGP internally. An example would be the joining of a number of large OSPE (Open Shortest Path First) networks where OSPF by itself would not scale to size. Another reason to use BGP is multihoming a network for better redundancy, either to multiple access points of a single ISP or to multiple ISPs.
Operation
When BGP runs between two peers in the same autonomous system (AS), it is referred to as Internal BGP (iBGP or Interior Border Gateway Protocol). When it runs between different autonomous systems, it is called External BGP (EBGP or Exterior Border Gateway Protocol).
Finite-state machines
BGP state machine
In order to make decisions in its operations with peers, a BGP peer uses a simple finite state machine (FSM) that consists of six states: Idle; Connect; Active; OpenSent; OpenConfirm; and Established. For each peer-to-peer session, a BGP implementation maintains a state variable that tracks which of these six states the session is in. The BGP defines the messages that each peer should exc

Video Key Points
You will need to have a good understanding of the key concepts from the three assigned videos in order to effectively complete the assignment.
So it would be a good idea to view the videos more than once, if you feel you need to, and to take notes on key points from each video.
Don't just focus on the answers to the questions that I have given you...each video has a lot of information that is relevant to this course. They all deal with socio/cultural issues, economic issues and environmental issues.
Also try and consider which of the United Nations 17 Sustainable Development Goals would be relevant in each video.
When viewing the videos consider some of the concepts that we have covered in class:
Socio/Cultural - acculturation, commodification, standardization, etc.
Capacity - social, physical, environmental, etc.
Video One - Case Study of Golf Course Development in Hainan China
Video Two - Case Study of the Mosuo Tribe in China
Video Three - The Economics of Happines

https://www.youtube.com/watch?v=pyQaUDLW6ts
· The questions pertain to the videos that you watched - The Mosuo Tribe, The Gold Course in Hainan China and The Economics of Happiness. You will also be expected to incorporate any relevant ideas and topics from the entire course, as you feel appropriate. And/or the question may pertain to the content of the Sustainable Management PowerPoint/class
· You will be asked in three of the questions to refer to those UN Sustainable Development Goals that you feel are relevant to the questions/your answers..
· The report should be no more than five pages long.
· Use the RUBRIC to guide you when answering.
· Cite all sources - as per APA standards. Do NOT just put a list of website addresses on the back page. Citing sources involves LINKING the source to the relevant text. If you are using information from our classes, PowerPoints, etc. you do not, for this assignment, need to cite the source APA style. You can simply say "as discussed in our class about Socio/Cultural Impacts".
Please put some thought into this paper. I want to hear your fact based opinions. I also want to see that you have watched and understood the videos and that you are able to connect their content to the theory that we discussed in our classes.
You will upload it into TURNITIN...as well as upload it into the Assignment Page in BlackBoard. As usual, the due date/time also applies to TurnitIN.
NOTE: PLAGIARISM includes cutting and pasting sentences and paragraphs from other sources. Even if you cite that source, using other people's work as the body of your work is not acceptable.

This presentation was made at the BCcampus Festival of Learning 2018 conference in Vancouver. It explored the health of individuals who participate in open education and how it might affect the well-being of the open education community as a whole. We asked: If members are not well, does this mean the group is also not thriving? This topic was also presented at the Open Education 2018 conference in Niagara Falls.

Perspective: The Journey of Narrative
We can learn a great deal about perspective by looking at our life through a new lens. The metaphor is a powerful narrative tool that presents a message indirectly. Choose a metaphor that best represents some aspect of your life and post an image of it in the box above. For example, if your life was full of wrong choices but is now leading you to new success, your metaphor might be the Phoenix. If you were always told you could never learn how to do something, but you learned how to do it well, your metaphor might be the wise owl. If you had a life-threatening illness or accident and fought your way through recovery, your metaphor might be a butterfly who passes through life stages in amazing ways. The possibilities are endless and will uniquely present a new perspective of 'you.'
After you post the image of your metaphor, please address the following:
· Explain your metaphor and why you chose it. Do this in a way that someone who has never met you will be able to connect with your story.
· What new understanding about yourself will this metaphor hold for you moving forward?
· How might understanding your life in terms of this metaphor help you let go of the mistakes or the pain of the past in a deeper way so that you can best engage your future?

First Person Narrative in Music
Music of all genres often tell first person narratives directly and indirectly. Go to YouTube and find an autobiographical music video that either reflects the singer's life using direct or figurative language. Select one that you feel has a strong narrative that needs to be told. For example, Amy Winehouse's song, Rehab, shares her struggle to find sobriety. Dolly Parton's, Coat of Many Colors, shares her struggle to understand how others viewed her family's poverty. Melissa Etheridge's song, California, which shares her courageous journey from the Midwest to California to pursue her music.

What has happened to the income share of the richest fifth of the U.S. population over the past 40 years?
A result that happened to the income share of the richest fifth is that they became more rich than they were. According to the book average income in 2006 richest fifth of the U.S households is $149,963. About 15 times as much income as the poorest fifth. From 1970- 2014 more unequal distribution.
What groups in the U.S. population are most likely to live in poverty?
The group may vary because that depends since the federal government has set up calculations that depend on the family size and gets adjusted every year depending on the changes in the level of prices.
When gauging the amount of inequality, why do transitory and life cycle variations in income cause difficulties?
While trying to distribute benefits in order to reduce poverty there are some difficulties dealing while dealing with improving society such as Welfare people take advantage of the options that are available so they can adjust with the requirements to apply for welfare such as they get encouraged to break up or encouraged to have babies in order to be qualified to gets those benefits by the government. Or instead of curing their illness that prevented them from working they exaggerate so they can keep benefit from those programs.
How would a utilitarian, a liberal, and a libertarian each determine how much income inequality is permissible?
In utilitarian cases the government tried to have more utility for the poor that way to rich people that way to avoid an inefficient use of resources.
Liberals insist on having policies available in order to protect people against the risk of lawsuit or other events.
Libertarians want to enforce more restricted laws that protect individuals and provide equal opportunities.
What are the pros and cons of in-kind (rather than cash) transfers to the poor?
The pros on in-kind process is that they provide them with a supplemental Nutrition Assistance Program SNAP so they can provide them to buy food on the store and Medicate Government tent to help poor people from surviving but do not encourage them to work.
Describe how antipoverty programs can discourage the poor from working. How might you reduce this disincentive? What are the disadvantages of your proposed policy?
The disadvantage of providing them benefits is that people get discouraged and aimed not to work. Some of them they are not 100% dissabled they still have some skills and availability to do certain things that will help the society, before providing full benefits to poor people they should test their percentage of abilities. Or at least reduce benefits when their income start to raise or provide benefits for limited period of time the verify who really needs it.

7. So you may be asking yourself what does this all mean?
Well, allow me to explain. The previous slides conclude that YouTube
uses all of the market segmentation strategies to appeal to every type of
target audience. Now of course I have not mentioned anywhere near the
total number of target audience examples within each of the four
strategies as there are to many to count. Many markets use a combination
of different target audience examples to even further pin point their
specific audience.
What I have done is provided some of the most prominent with
examples of how the content of YouTube relates to that target audience.
This clearly displays that YouTube is for everyone!
No matter where you live, what you do, how old you
are or even what food you eat, something on YouTube
