A computer network and a database are used to provide a hardware-independent, dynamic information system in which the information content is entirely user-controlled. Requests are received from individual users of the computer network to electronically publish information, and input is accepted from the individual users. Entries from the users containing the information to be electronically published are automatically collected, classified and stored in the database in searchable and retrievable form. Entries are made freely accessible on the computer network. In response to user requests, the database is searched and entries are retrieved. Entries are served to users in a hardware-independent page description language. The entries are password protected, allowing users to retrieve and update entries by supplying a correct password. Preferably, the process is entirely automated with any necessary billing being performed by secure, on-line credit card processing. The user making a database entry has complete control of that entry both at the time the entry is made and in the future after the entry has been made. The entry, when served to a client, is transformed on-the-fly to the page description language. Where the page description language is HTML and the computer network is the World Wide Web, the entry may function as a “mini” homepage for the user that made the entry. Provision is made for graphics and other kinds of content besides text, taking advantage of the content-rich nature of the Web.

HERMES: an infrastructure for low area overhead packet-switching networks on chip

A large fraction of today's Internet applications are internally publish/subscribe in nature; the current architecture makes it cumbersome and inept to support them. In essence, supporting efficient publish/subscribe requires data-oriented naming, efficient multicast, and in-network caching. Deployment of native IP-based multicast has failed, and overlay-based multicast systems are inherently inefficient. We surmise that scalable and efficient publish/subscribe will require substantial architectural changes, such as moving from endpoint-oriented systems to information-centric architectures.In this paper, we propose a novel multicast forwarding fabric, suitable for large-scale topic-based publish/subscribe. Due to very simple forwarding decisions and small forwarding tables, the fabric may be more energy efficient than the currently used ones. To understand the limitations and potential, we provide efficiency and scalability analysis via simulations and early measurements from our two implementations. We show that the system scales up to metropolitan WAN sizes, and we discuss how to interconnect separate networks.

Architectures for the future networks and the next generation Internet: A survey

Software-Defined Networking (SDN) refers to a new approach for network
programmability, that is, the capacity to initialize, control, change,
and manage network behavior dynamically via open interfaces. SDN
emphasizes the role of software in running networks through the
introduction of an abstraction for the data forwarding plane and, by
doing so, separates it from the control plane. This separation allows
faster innovation cycles at both planes as experience has already
shown. However, there is increasing confusion as to what exactly SDN
is, what the layer structure is in an SDN architecture, and how layers
interface with each other. This document, a product of the IRTF
Software-Defined Networking Research Group (SDNRG), addresses these
questions and provides a concise reference for the SDN research
community based on relevant peer-reviewed literature, the RFC series,
and relevant documents by other standards organizations.

Software-Defined Networking (SDN): Layers and Architecture Terminology

The early successes of computer networks in the mid-1970's made it apparent that to utilize the full potential of computer networks, international standards would be required. In 1977, the International Standards Organization (ISO) initiated work on Open Systems Interconnection (OSI) to address these requirements. This paper briefly describes the OSI Reference Model. The OSI Reference Model is the highest level of abstraction in the OSI scheme. The paper first describes the basic building blocks used to construct the network model. Then the particular seven-layer model used by OSI is briefly described, followed by a discussion of outstanding issues and future extensions for the model.

Groundbreaking Patterns for Building Simpler, More Powerful Networks

In Patterns in Network Architecture, pioneer John Day takes a unique approach to solving the problem of network architecture. Piercing the fog of history, he bridges the gap between our experience from the original ARPANET and todays Internet to a new perspective on networking. Along the way, he shows how socioeconomic forces derailed progress and led to the current crisis.

Beginning with the seven fundamental, and still unanswered, questions identified during the ARPANETs development, Patterns in Network Architecture returns to bedrock and traces our experience both good and bad. Along the way, he uncovers overlooked patterns in protocols that simplify design and implementation and resolves the classic conflict between connection and connectionless while retaining the best of both. He finds deep new insights into the core challenges of naming and addressing, along with results from upper-layer architecture. All of this in Days deft hands comes together in a tour de force of elegance and simplicity with the annoying turn of events that the answer has been staring us in the face: Operating systems tell us even more about networking than we thought. The result is, in essence, the first unified theory of networking, and leads to a simpler, more powerfuland above allmore scalable network infrastructure. The book then lays the groundwork for how to exploit the result in the design, development, and management as we move beyond the limitations of the Internet.

Using this new model, Day shows how many complex mechanisms in the Internet today (multihoming, mobility, and multicast) are, with this collapse in complexity, now simply a consequence of the structure. The problems of router table growth of such concern today disappear. The inescapable conclusion is that the Internet is an unfinished demo, more in the tradition of DOS than Unix, that has been living on Moores Law and 30 years of band-aids. It is long past time to get networking back on track.

Patterns in network protocols that synthesize contradictory approaches and simplify design and implementation

Deriving that networking is interprocess communication (IPC) yielding

A distributed IPC model that repeats with different scope and range of operation

Making network addresses topological makes routing purely a local matter

That in fact, private addresses are the normnot the exceptionwith the consequence that the global public addresses required today are unnecessary

That mobility is dynamic multihoming and unicast is a subset of multicast, but multicast devolves into unicast and facilitates mobility

That the Internet today is more like DOS, but what we need should be more like Unix

For networking researchers, architects, designers, engineers

Provocative, elegant, and profound, Patterns in Network Architecture transforms the way you envision, architect, and implement networks.

Patterns in Network Architecture: A Return to Fundamentals

In 1986 the Kendall Whaling Museum (Sharon, Massachusetts) acquired a panel of a Chinese map as an example of the Chinese representation of the monstrous fish (whales) mentioned by Herman Melville in his assessment of eighteenth‐ and nineteenth‐century depictions of whales. Only later was the panel identified as a rare seventeenth‐century variation of Matteo Ricci's world map of 1602. In this paper, the museum's map is compared with other manuscript and printed maps by Matteo Ricci. Discussion centres on the origins of the manuscript copies of Ricci's 1602 map and their inter‐relationships. A census of woodblock prints of Ricci's maps (1602, 1603, post‐1644) and of the Chinese manuscript copies is included.
