Chimera (software Library)
Chimera is a software library created as a research project at UCSB for the C programming language that implements a structured, peer-to-peer routing platform to allow the easy development of peer-to-peer applications. The project's focus is on providing a fast, lightweight implementation of a system like other prefix-routing protocols such as UCSB's Tapestry system and Microsoft Research's Pastry system, that can be easily used to build an application that creates an overlay network with a limited number of library calls. The library is intended to serve as both a usable complete structured peer-to-peer system and a starting point for further research. It includes some of the current work in locality optimization and soft-state operations. The system contains both a leaf set of ''neighbor nodes'', which provides fault tolerance and a probabilistic invariant of constant routing progress, and a PRR-style routing table to improve routing time to a logarithmic factor of network size ...

University Of California, Santa Barbara
The University of California, Santa Barbara (UC Santa Barbara or UCSB) is a Public university, public Land-grant university, land-grant research university in Santa Barbara County, California, United States. Tracing its roots back to 1891 as an independent teachers college, UCSB joined the University of California system in 1944. It is the third-oldest undergraduate campus in the system, after University of California, Berkeley, UC Berkeley and University of California, Los Angeles, UCLA. UCSB's campus sits on the oceanfront site of a converted WWII-era United States Marine Corps, Marine Corps air station. UCSB is organized into three undergraduate colleges (UCSB College of Letters and Science, Letters and Science, UCSB College of Engineering, Engineering, College of Creative Studies, Creative Studies) and two graduate schools (Gevirtz Graduate School of Education, Education and Bren School of Environmental Science & Management, Environmental Science & Management), offering more ...

C Programming Language
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

Peer-to-peer
Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the network, forming a peer-to-peer network of Node (networking), nodes. In addition, a personal area network (PAN) is also in nature a type of Decentralized computing, decentralized peer-to-peer network typically between two devices. Peers make a portion of their resources, such as processing power, disk storage, or network bandwidth, directly available to other network participants, without the need for central coordination by servers or stable hosts. Peers are both suppliers and consumers of resources, in contrast to the traditional client–server model in which the consumption and supply of resources are divided. While P2P systems had previously been used in many application domains, the architecture was popularized by the Internet file sharing system Napster, originally released in ...

Tapestry (DHT)
Tapestry is a peer-to-peer overlay network which provides a distributed hash table, routing, and multicasting infrastructure for distributed applications.{{cite journal , last1=Zhao , first1=Ben Y. , last2=Huang , first2=Ling , last3=Stribling , first3=Jeremy , last4=Rhea , first4=Sean C. , last5=Joseph , first5=Anthony D. , last6=Kubiatowicz , first6=John D., date=2004 , title=Tapestry: A Resilient Global-scale Overlay for Service Deployment , url=http://pdos.csail.mit.edu/~strib/docs/tapestry/tapestry_jsac03.pdf , journal=IEEE Journal on Selected Areas in Communications , volume=22 , issue=1 , pages=41–53 , doi=10.1109/JSAC.2003.818784 , access-date=13 January 2015, citeseerx=10.1.1.71.2718 , s2cid=689430 The Tapestry peer-to-peer system offers efficient, scalable, self-repairing, location-aware routing to nearby resources.

Microsoft Research
Microsoft Research (MSR) is the research subsidiary of Microsoft. It was created in 1991 by Richard Rashid, Bill Gates and Nathan Myhrvold with the intent to advance state-of-the-art computing and solve difficult world problems through technological innovation in collaboration with academic, government, and industry researchers. The Microsoft Research team has more than 1,000 computer scientists, physicists, engineers, and mathematicians, including Turing Award winners, Fields Medal winners, MacArthur Fellows, and Dijkstra Prize winners. Between 2010 and 2018, 154,000 AI patents were filed worldwide, with Microsoft having by far the largest percentage of those patents, at 20%.Louis Columbus, January 6, 201Microsoft Leads The AI Patent Race Going Into 2019 ''Forbes'' According to estimates in trade publications, Microsoft spent about $6 billion annually in research initiatives from 2002 to 2010 and has spent from $10–14 billion annually since 2010.

Soft State (computer Science)
In computer science, soft state is state which is useful for efficiency, but not essential, as it can be regenerated or replaced if needed. The term is often used in network protocol engineering. It is a term that is used for information that times out (goes away) unless refreshed, which allows protocols to recover from errors in certain services. The term was coined by David D. Clark in his description of the Defense Advanced Research Projects Agency (DARPA) internet protocols. While in general less efficient than well-designed "hard state" protocols when tuned for a particular network regime, soft state protocols behave much better than hard state protocols in an unpredictable network environment such as the Internet The Internet (or internet) is the Global network, global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a internetworking, network of networks .... Reference ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Department Of Defense
The United States Department of Defense (DoD, USDOD, or DOD) is an United States federal executive departments, executive department of the federal government of the United States, U.S. federal government charged with coordinating and supervising the six U.S. armed services: the United States Army, Army, United States Navy, Navy, United States Marine Corps, Marines, United States Air Force, Air Force, United States Space Force, Space Force, the United States Coast Guard, Coast Guard for some purposes, and related functions and agencies.
