  • Communication Architecture Strategy for connecting host computers and other communicating equipment. Defines necessary elements for data communication between devices. A communication architecture, therefore, defines a standard for the communicating hosts. A programmer formats data in a manner defined by the communication architecture and passes it on to the communication software. Separating communication functions adds flexibility, for example, we do not need to modify the entire host software to include more communication devices....

  • Surface electrochemically plated with nickel and highly inert particles provides useful applications: Ni–CeO2 as chemical catalysts, high hardness Ni–CBN (cubic boron nitride) as grinding tools, among others. The plating’s inert particles – 100 μm in size – on nickel surface need to be tightly adherent and evenly dispersed; it is therefore necessary to determine and control the coating layer’s thickness corresponding to the inert particles’ size by parameters like electrical current density and time.

  • OSI Transport Layer. In this chapter, we examine the role of the Transport layer. The Transport layer also encompasses these functions: Enables multiple applications to communicate over the network at the same time on a single device. Ensures that, if required, all the data is received reliably and in order by the correct application. Employs error handling mechanisms. Learning Objectives–Upon completion of this chapter, you will be able to: Explain the need for the Transport layer.

  • This lab focuses on the Telnet (remote terminal) utility to access routers remotely. Telnet is used to connect from a local router to another remote router in order to simulate being at the console on the remote router. The local router acts as a Telnet client and the remote router acts as a Telnet server. Telnet is a good testing or troubleshooting tool since it is an application layer utility. A successful Telnet demonstrates that the entire TCP/IP protocol stack on both the client and server are functioning properly. Telnet from the workstation as a client into any router with...

  • This paper presents the design and implementation of DOT, a flexible architecture for data transfer. This architecture separates content negotiation from the data transfer itself. Applications determine what data they need to send and then use a new transfer service to send it. This transfer service acts as a common interface between applications and the lower-level network layers, facilitating innovation both above and below. The transfer service frees developers from re-inventing transfer mechanisms in each new application.

  • Raw Sockets let you program at just above the network (IP) layer You could program at the IP level using the IP API but you can’t get at ICMP Raw Sockets expose ICMP you get a Raw Packet and populate the entire packet yourself for high level protocols like TCP and UDP you lose all of the functionality implemented in those layers choosing to use a Raw Socket must be weighed carefully Raw Sockets can be dangerous Raw Sockets can be against the law http://www.kumite.com/rsnbrgr/rob/grcspoof/cnn/ ...
