Measurements on a high-performance Ethernet are shown to match well a truncated Cauchy probability distribution, with a much better fit over smaller file/request sizes than the commonly used Pareto distribution. We observe self similar characteristics in the traffic at both file servers and at a CPU server elsewhere in the network, which targets, predominantly, file and web servers. This sugges...

Optical network is a viable network for future communication, which transmits data at an average rate of 50Tb/s. Optical Burst Switching is a trusted mechanism used for Optical network. There is a good amount of research done in the area of security in Optical networks. In addition, the issues related to physical network security has been dealt with respect to Optical networks. Our proposed wor...

A new optical packet switching network and its enabling technologies are investigated for implementation in a Petaflops scale supercomputer system. We capitalize on the immense bandwidth of the optical fiber interconnects by deploying WDM/TDM packet payloads. To accommodate current optical switching technologies, the routing operations in the network are drastically simplified and the need for ...

Malathi Veeraraghavan Mark Karol Polytechnic University Lucent Technologies 6 Metrotech Center 101 Crawfords Corner Road Brooklyn, NY 11201 Holmdel, NJ 07733 [email protected] [email protected] ABSTRACT: The use of connection-oriented (CO) networks for the transport of IP traffic is seen to have value to both users and service providers. Given the expectation that most endpoint-generated traffic will ...

A Wavelength Switched Optical Network (WSON) requires certain key information fields be made available to facilitate path computation and the establishment of Label Switched Paths (LSPs). The information model described in "Routing and Wavelength Assignment Information Model for Wavelength Switched Optical Networks" (RFC 7446) shows what information is required at specific points in the WSON. P...

A new algorithm for path selection in Automatically Switched Optical Networks is presented and demonstrated. This algorithm is based upon Eye Closure Penalty and involves a simple modification of the current OSPF protocol. ASON, path selection, OSPF, Eye Closure Penalty

Src tyrosine kinases are essential in numerous cell signaling pathways, and improper functioning of these enzymes has been implicated in many diseases. The activity of Src kinases is regulated by conformational activation, which involves several structural changes within the catalytic domain (CD): the orientation of two lobes of CD; rearrangement of the activation loop (A-loop); and movement of...

Measurements on a high-performance switched Ethernet system are presented that reveal new insights into the statistical nature of le server and web server traÆc. Both le sizes and data requested from the web server are shown to match well a truncated Cauchy distribution. This is a distribution with heavy tails similar in nature to the commonly used Pareto distribution but with a much better t o...

IP traceback is the generic term given to systems that allow the tracing of IP packets back to their originating machine. A common shortcoming shared by existing traceback proposals is that they are able to identify the source network, but not the source host. Our work extends the traceback process by allowing the tracing of frames within the originating network (once this has been identified) ...

This paper proposes a scheme for taking advantage of the properties of both connectionless (CL) and connection-oriented (CO) networks to carry traffic from existing applications. Specifically, it proposes a solution for allowing data generated by endpoints on a CL (IP) network to be redirected to CO networks if there is an advantage from the user or service provider perspective. The advantage t...
