29. Pg 254 Point to Point Multiplexing. Used with external modems and internal modems. It does not require a MAC protocol. Functions at the Physical and data link layers.

2110: In general, MPI implementations are installed in clusters where some machines nodes are connected via a high-speed network connection to ensure a minimum communication latency.

layer 1 | Hubs, repeaters, network adapters, Parallel SCSI buses. Various physical-layer Ethernet incorporates both this layer and the data-link layer. Token ring, FDDI, and IEEE 802.11. | - |

This type of network is designed to provides a secure, encrypted tunnel in which to transmit the data between the remote user and the company network” (Beal). VPN uses encryption to provide data confidentiality. Virtual Private Networks makes use of encryption and special protocols to provide extra security.

VLANs or Virtual Local Area Networks are logical local area networks that extend beyond the traditional LAN architecture. Because a VLAN is a logical entity, creating and configuring a VLAN is done completely in software. The advantages to using this type of LAN include but are not limited to the ability to conserve the network resources, to bridge geographical drawbacks, and to better manage the movement of personnel and equipment. To understand the need for VLANs you must first understand the Local Area Network (LAN). The definition of a LAN started as a group of computers that were connected in the same area, but today’s LAN is defined as a single broadcast domain. This is explained easily by looking at a large organization where each department would be on a separate LAN found behind a router or switch. With today’s expanding networks it has become important for these

and across the network. Typically, this is a TCP/IP packet. This basically tells you what the format of the

are setup, then data (packets) transmissions will be as fast and easy as in the tradition wired

In a bus topology, all segments are associated with and share a solitary wire. Certain media sorts, for example, 10Base5 and 10Base2 Ethernet, utilize a bus topology. Regularly, unique sorts of connectors or handsets are utilized to interface the links to give the bus topology. In 10Base5, for instance, every gadget interfaces with a solitary strand of the coaxial link by means of a vampire tap. This gadget takes advantage of the single strand of the coaxial link and gives the physical association from a systems administration gadget to the single strand of the link. (Deal, 2015)

If a business is looking for a way to have a system that is fast and reliable, as well as secure MPLS is the best solution. MPLS helps with the transfer of data between different business locations and it has the ability to scale for any size business so it makes it a very valuable investment. MPLS takes away all constant routing lookups associated with regular IP routing and provides high quality performance for company networks.

MPLS has many advantages over competitive services. It was originally developed as a faster technique for moving data between LANs. Since only a single router has to fully inspect incoming traffic, and all others are merely reacting to the conclusions of this original inspection, speed is improved from the paradigm. However many advancements in hardware have somewhat closed the gap on this difference. Nonetheless, MPLS remains a fair choice for those who wish to optimize the speed of their network, and it has many things to offer beyond that original intent. The "Multiprotocol" part of it's name is important in explaining many of these perks. What is meant by multiprotocol is that it's compatible with any network layer protocol. And not only that, it's also friendly with other WAN services such as Frame Relay and ATM. This means that any existing legacy networks or variant adjacent WANs will play well

Key tools utilized, variable length subnet masking and route summarization are explained as well. Here choosing the appropriate routing protocol is equally critical for a successful design. To implement different masks for the same major network it is necessary to have a routing protocol that supports VLSM. Such routing protocols are called classless routing protocols. They carry the mask information along with the route advertisements therefore allowing for the support of more than one mask.

Introduction: This paper mainly deals with disadvantages of the PBB and when used in unison with MPLS how it is going to be advantageous to the service provider networks. An example is illustrated to explain how this combination benefits and its results are provided.

Well-known communications protocols are Ethernet, a hardware and Link standard that is ubiquitous in local area networks, and the Internet Protocol Suite, which defines a set of protocols for internetworking, i.e. for data communication between multiple networks, as well as host-to-host data transfer, and application-specific data transmission formats.

MPLS has evolved as a complex and efficient solution for ISPs for the purposes of traffic engineering and enterprise L2 and L3 VPN services, traffic engineering in turn serves the purpose of maximizing the utilization of infrastructure while VPNs offer secure connection services to enterprises, this feature

MPLS (multi-protocol label switching) is defined by IETF in 1998. It works between layer 2 and layer 3 protocol so it refers as a 2.5 layer protocol. It works independently at the layer 2 technologies. It can be used over any layer 2 technologies including PPP, frame relay, Ethernet or ATM. It is a label-based switching method; this method allows routers to make forwarding decisions based on the contents of a MPLS label. Service providers can offer MPLS services similar to traditional WAN technologies (frame relay, leased line, ATM services) at lower costs and provide additional IP-based services, which was not available previously.
