Named data networking - Term Paper Example Named data networking is a new architecture that has been developed to revolutionize the current internet architecture. There is no doubt the network engineers have made significant development in the current network design. Indeed, current networks have many innovations that have transformed how data are shared between various computers connected to the internet. Despite these, the same network is characterized by many challenges that have hindered the transfer of data between different endpoints. However, the named data networking is a paradigm that is poised to overcome the many challenges facing current implementation of networks. The introduction of named data networking will give more emphasis on data, liberate content from providers and provide a myriad of benefits to computer users, despite having some limitations. How named data network works The development of the named data networking is based on a number of concepts that work to improve how data is shared across the inter net. These concepts shape the function of any named data network based on the principle of named data networking. In a named data networking, each piece of data has a name, which uniquely identifies the data anywhere in the network configuration. In addition, all pieces of data provide more information on what they contain rather than what they are. The change from who to what is a significant shift that defines how named data networks function (Chen, Goes, & Marsden 154). ... This is a process where data are signed with unique signature name that also secure the metadata. The specific signatures are public keys with binding enforced between names and data. Because of this, a named data network does not need a name lookup process. Named data networks also have encryption mechanism that secures packets during transit from one location to another. Naming principles are a core function that influences the functioning of named data network. In a named data network, variable length identifiers are used to name data thus categorizing them into hierarchies. Content versions and segments are used to characterize information at the lower levels of a named data network (Serpanos and Wolf 23). When in use, the named data network works by specifying how information can traverse the network. The selection process is done when a host sends an interest group. The transport strategy in named data networks entails sending of single data packets in response to each interest packet received. In some instances, network hosts can send many interest packets to ensure that flow of data is controlled in some applications. With the difficulty of flow control, network nodes learn the best strategy to send their packets to support an end-to-end communication. Content segments are also used to replace TCP sequence numbers in use. Named data networks have different routing mechanism. A named data network makes use of a mechanism that provides link advertisement between various nodes. This advertisement provides includes a named prefix. Similarly, OSPF protocols can be used to achieve intra-domain routing that includes type-label values that indicated in the protocol segment. The use of names removes the challenge of using IP architecture for routing
