Network Layer

Core The core layer is the backbone layer of the network running at high speed switching, transferring large amounts of data and also handling the requests of the distribution layer . This layer has high speed devices; the most implementations have layer 3 switches or high end routers. Its key characteristics are: redundancy, fast transport of large amounts of data, high reliability and availability, low latency. The core layer should not do any packet manipulation. The distribution layer acts as a services

Milestone 2 Network Requirements 1 Physical, Data Link, Network Layers Management Integration System ClearLeaf MIS Prepared by: Shams Bin Shahid Anaugh Date: 01/23/2016 Approved by: Physical media Physical media is found on the physical layer of the OSI model. Therefore physical media includes cabling and equipment, wiring and the frequencies defined to transfer data between two points. Physical media is what physically connects the computers connected on the internet. For this network two physical

IP Addressing IP operates on the Network Layer of the reference model. IP addressing is important because IP helps in routing packets, just us the Post Office needs an address on a packet or letter for correct delivery. IPV4 is made up of 32-bit addresses, as opposed IPV6 which has 128-bits, and this obviously larger address space has become necessary because the world is running short of IPV4 addresses. Most of the internet now uses IPV4, so this discussion will mostly concentrate on IPV4. A lot

The Core Layer, which is the trusted computing base internal network of the GFI network, houses the servers that are the heart of the organization. The Core acts as the backbone of the GFI network. The Core has six servers all with specify roles in caring out the daily operations of the business. The core is primarily responsible for transmitting data, processing instructions, and managing the network as a whole. The network architecture used for the GFI network allows for interconnection and communication

Internet Protocol is one of the protocol in TCP/IP protocols suite. This protocol works at Network layer of OSI model and at Internet layer of TCP/IP model. This protocol has the responsibility of identification of hosts based upon their logical addresses and to route data between/among them over the underlying network. Internet Protocol is a set of technical rules that defines how computers communicate over a network. There are currently two versions: IP version 4 (IPv4) and IP version 6 (IPv6). This

What does the network layer do? Where does it sit in relationship to the other four layers of our simplified network model? Network layer is the third layer of the OSI model. It performs switching and routing by creating logical paths, known as virtual circuits, for transferring data from one node to another node. Routing and forwarding are the major functions of this layer. It also performs other operations such as addressing, internetworking, error handling, congestion, control and packet

Data Link and Network Layer Protocols in TCP/IP Protocol Difference Between Ethernet II and Ethernet 802.2 LLC Frame Structures Ethernet II framing structure is also commonly referred to as DIX Ethernet (Carrell, Chappell, Tittel & Pyles, 2013). This frame structure was developed by DEC, Intel, and Xerox and thus the DIX acronym that represent these major players in its development (Carrell et al., 2013). The Ethernet II defines a two-octet field of EtherType (Carrell et al., 2013). The MAC address

Laser 12. Which one answer lists the most likely place to find a fiber-optic link in a campus Ethernet LAN? D. Between two switches in different buildings in the same office park 13. This chapter describes SONET, a family of physical layer standards used in telco networks over the last few decades. Which of the following are true about the slow and fast end of the optical carrier (OC) standards mentioned in this book: OC-1 and OC-192? (Choose two answers) A. OC-1 runs at approximately 52 Mbps D. OC-192

TCP/IP and what do they do? Who is the primary user of TCP/IP? TCP/IP has two parts. TCP is the transport layer protocol that links the application layer to the network layer. It performs segmenting: breaking the data into smaller PDUs called segments, numbering them, ensuring each segment is reliably delivered, and putting them in the proper order at the destination. IP is the network layer protocol and performs addressing and routing. IP software is used at each of the intervening computers through

each other. Through the analysis of ethnic proximity, ethnic distance, shared goal structure, separate goal structure, and personal network integration, the situation layer of Kim’s Interethnic Theory will be explored. A Contextual Theory of Interethnic Communication As conceptualized by Young Yun Kim, the interethnic communication theory describes the multifaceted layers and factors in communication event. Described as an open system, interethnic communication occurs between communicators and their
