Research Paper Instructions:

Please answer these three questions in a single word document with citations as necessary.
These questions can be answered in 1 typed 12 points double-spaced Times New Roman font page with 1-inch margins each. Do not exceed this 3 page limit (not including the citation list at the end and a title page).
1)
MPLS (Multi-Protocol Label Switching) is a very important protocol because it reduces look-up times and creates a switching environment that removes level three complexity from the internals of the cloud where switched circuits can be used to move any protocols across the net. Watch the movie at https://www(dot)youtube(dot)com/watch?v=4QGRLgIq8iA called
Very Basic MPLS Tutorial this video provides not only a tutorial of MPLS but shows Wireshark traces of the protocol in action toward the end of the video. Watch this in its entirety. Then using what you know about learning new protocols (structure,
FSM and Config) explain to me how MPLS works and how it fits in with the other protocols. Also, discuss the benefits of the MPLS concept in terms of this simple example.
2) Explain why you think packet switching (current implementation of IP) has had the success that it has had for so long. Why is it that a roughly 40-year-old protocol has existed for so long and is able to support very high-end network applications such as voice, video, and very high-density data-driven applications? (no more than one page)
3) Explain how the concept of the Autonomous System supports the large-scale implementation of the Internet. Explain how the AS addresses the large-scale convergence problem in the network. How do the store and forward nature of packet-switched networks like IP benefit us when used in conjunction with the concept of Autonomous systems?

Q1 Multi-Protocol Label Switching (MPLS)
Within telecommunication networks, MPLS refers to a routing technique that directs data between two nodes through short path labels instead of the extended network address (Mazhin, Bag-Mohammadi, Ghasemi, & Feizi, 2017). By choosing short path labels over long network addresses, MPLS eliminates the need for complex lookups in a given routing table. As a result, it speeds up the traffic flow making the telecommunication network efficient. The technique is referred to as 'multiprotocol' because of its capability to encapsulate data packets from different network protocols. MPLS technique can be integrated over existing infrastructure like Ethernet, Frame Relay, and IP and allows subscribers from diverse access links to be aggregated without alterations in the current environment. The technique is commonly used in enterprises that require real-time applications, metro ethernet services, branch offices, and campus networks.
The functionality of MPLS relies on the efficiency of the Label Switched Paths (LSPs). LSP is a predetermined and unidirectional path between a pair of routers within an MPLS network. In such a network, a data packet enters through the ingress node (Label Edge Router), where it is assigned to a Forwarding Equivalence Class (FEC) which determines the type of data and where it is intended to go and whether a swap, push, or pop are required (Ibikunle, Oloja, & Philip, 2013). The purpose of the FEC is to identify data packets with identical characteristics. Based on the FEC outcomes, the ingress node does two things. Firstly, it applies a label to the packet giving it a unique characteristic. Secondly, it encapsulates the packet into an LSP, enabling MLPS to fit and function seamlessly in any network. The packet data moves through the network's transit nodes (LSR), with the routers directing data based on the instructions included in the packet label (Mazhin et al., 2017). The instructions are vital because they show what type of packet the transit nodes are handling at that moment and its intended destination. The transit nodes cause in-between stops for the packet movement by relying on the packet's label instead of requiring additional IP lookups as experienced in new networks. When the packet reaches the destination router at the tail end of the LSP, the network removes the label delivering the packet as a regular IP routing.
A key advantage of MPLS is that it seamlessly fits in with other protocols. It can separate the forwarding mechanisms from underlying data-link services and create forwarding tables for any protocol. Due to its robust functionality, MLSP has several benefits. Firstly, although MPLS does not provide encryption capabilities, it can be considered a virtual private network and partitioned from the public access internet (Ibikunle, Oloja, & Philip, 2013). This makes it a secure transport mode for data t...
