  ICE: Networking Models   (Site not responding. Last check: 2007-10-12)
The OSI 7-layer model is not in fact a model of any one specific network implementation, but is a general and very comprehensive model which can be applied to any network.
The TCP/IP reference model, or four-layer model, is a model of a far more concrete and very widely implemented network structure: it is the model on which the Internet is based.
The four layers each have separate functions, as in the OSI model; however the various functions are not as well separated in the TCP/IP model; OSI's layers 1 and 2 are merged into the Host-to-Network layer, and the OSI sesion layer in particular is hard to locate within the TCP/IP model.

 Network Protocol Levels   (Site not responding. Last check: 2007-10-12)
This model is sometimes called the DOD model since it was designed for the department of defense It is also called the TCP/IP four layer protocol, or the internet protocol.
Network - Corresponds to the network layer of the OSI model and includes the IP, ICMP, and IGMP protocols.
When starting with protocols that work at the upper layers of the network models, each set of data is wrapped inside the next lower layer protocol, similar to wrapping letters inside an envelope.

 Network Layers   (Site not responding. Last check: 2007-10-12)
Each layer of a specific network model may be responsible for a different function of the network.
The OSI network model layers are arranged here from the lower levels starting with the physical (hardware) to the higher levels.
Each network layer either encapsulates the data stream with additional information, or manages data handling or come part of the connection.

 Internetworking Basics
Network topology consists of the data link layer specifications that often define how devices are to be physically connected, such as in a bus or a ring topology.
A packet is composed of the network layer header (and possibly a trailer) and upper-layer data.
The relationship between a network address and a device is logical and unfixed; it typically is based either on physical network characteristics (the device is on a particular network segment) or on groupings that have no physical basis (the device is part of an AppleTalk zone).

 Fool.com: Telecom and Networking Business Models (News -- Telecom Sector)
Calling this an "agnostic" model may be useful, as the term rightly downplays the smaller role that cutting-edge intellectual property plays as a competitive advantage.
Of the structural models of data/voice convergence, the newest and arguably least understood strategy is that of the Standard.
The network is the network, and computers, telephones, televisions, energy services, data assistants, and the Internet will become agents of delivery of data residing throughout the network.

 The TCP/IP Guide - The Benefits of Networking Models
One of the ways in which networking technology is made easier to understand is by splitting it into pieces, each of which plays a particular role, or is responsible for a specific job or function.
The model defines networking functions not as a large, complicated whole, but as a set of layered, modular components, each of which is responsible for a particular function.
The result is better comprehension of network operations, improved performance and functionality, easier design and development, and the ability to combine different components in the way best suited to the needs of the network.

 Networking Models: ISO OSI 7 Layer Reference Model + TCP/IP 5 Layer Model
Networking Models: ISO OSI 7 Layer Reference Model + TCP/IP 5 Layer Model
The ISO, and the OSI 7 Layer Reference Model for Networking(Rough First Draft) is useful in understanding how a suite of protocols could be implemented.
A forcing of the TCP/IP suite of protocols into a 5 layer model based on function (Rough First Draft) can be helpful in seeing how TCP/IP does not conform to the standards set up by the ISO for networking protocols that would meet the ISO specifications for 7 layer networking protocol stacks.

 ADMINISTRATIVE AND NETWORKING STRATEGIES:
These new trends were very much consonant with the world-wide crisis of hierarchical models and the mushrooming of networking models of management, which in Russia have their own specific characteristics.
The networking actors are in most cases the leaders of public opinion, making specific demands upon government representatives on behalf of identifiable interests in society.
Learning to live in the world of networking relations (including using communication technologies, recruiting a skilled labour force, and business education) is a difficult challenge for the region’s political and economic actors.

 Internet Protocols (IP)
Each host on a TCP/IP network is assigned a unique 32-bit logical address that is divided into two main parts: the network number and the host number.
Subnetting provides the network administrator with several benefits, including extra flexibility, more efficient use of network addresses, and the capability to contain broadcast traffic (a broadcast will not cross a router).
The reference charts shown in table 30-2 and table 30-3 can be used when planning Class B and C networks to determine the required number of subnets and hosts, and the appropriate subnet mask.

 Definition of Networking
The most common topologies or general configurations of networks include the bus, star, and ring topologies (See the image on the Main page).
Networks can also be characterized in terms of spatial distance as local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs).
Large telephone networks and networks using their infrastructure (such as the Internet) have sharing and exchange arrangements with other companies so that larger networks are created.

 Microsoft Windows NT Networking Models
Workgroup networks, or peer-to-peer networks, are network models that offer ease of setup, noncentralized security, and low costs as their key benefits.
This model balances the requirements for account security with the need for readily available resources on a network because users obtain permission to access resources based on their master domain logon identity.
Depending on your networking model and your definition of administration, new administrators can be added either into the global Domain Admins, effectively granting permissions to all servers in the domain, or into the local Administrators group on specific machines, thereby granting permissions only to the specified computers.

 Chapter 1: What is a Community Network?
Wonderful stories were told of grassroots champions creating community networking opportunities to ‘bring people together to make good things happen.’ The vision of the potential for dramatic electronic extension of the impact of the goodwill of citizens began to flower.
After the WWW appeared, this was the rarest model, ironically the model of the original Freenets, dedicated to creating a public forum for discussion and was based primarily on supporting civic collaboration through web-based text systems, or a combination of both web-based and older text-based systems.
While this model might be overly simplistic, within any geographical community many different overlapping communities exist, each with their own special interests, including the ethnic and religious communities, as well as the various other communities of interest; the many clubs, social organizations, and so on.

What's new is the addition of Virtual Networks where connections are initially made through avatar interaction, thanks to Andrew Phelps.
The result will be clusters of social networks with a more random distribution of link scale, reasonably maxing out at 150 connections per person.
Because the requirements for connections are high the network will not grow as fast as other systems, but the network's value will be higher because of its web of trust.

 DRM Watch: Integrating DRM with P2P Networks: Enabling the Future of Online Content Business Models
Sun Microsystems's Network File System (NFS), which emerged even earlier and enabled all computers on a network to make their file directories available in a network-wide hierarchy, can also be considered as a form of peer-to-peer.
Napster was actually not a pure P2P network, because it relied on a central server to act as a catalog of files on the network and their locations.
Both of these networks were designed without central servers so as to avoid Napster's legal fate, but even FastTrack is not a pure peer-to-peer service: it relies on so-called supernodes, which constitute the first level of connectivity in the network and help make request routing decisions.

 My Take on Social Networking Business Models (by Jeremy Zawodny)
What we call social networking today will be a feature - and represents the 'raising of the bar' - as we saw multimedia due at the turn of the decade before ('89-'91).
Social networking is currently being built into business networking, dating and jobs/classified ad services.
As a complete aside, the oldest social network spanning wider ranges than just a village or similar is the network of a French dove breeder club.
