		Today, the speed of store-and-forward switches has caught up with cut-through switches to the point where the difference between the two is minimal.
		When a packet is received by the switch, the switch examines the destination and source hardware addresses and compares them to a table of network segments and addresses.
		Switches map the Ethernet addresses of the nodes residing on each network segment and then allow only the necessary traffic to pass through the switch.

	LAN switching
		In cell switching, a frame at the input port is broken into the cells and is reassembled at the output port.
		LAN switching is a technology that promises to increase the efficiency of local area networks and solve the current bandwidth problems.
		LAN switching is considered to be a solution to this problem and has been adopted by many organizations.

	Cisco Sem3 Lesson 2 - LAN Switching
		Store and forward packet switching - Packet-switching technique in which frames are completely processed before being forwarded out the appropriate port.
		A device using cut-through packet switching reads, processes, and forwards packets as soon as the destination address is looked up, (first 16 bytes) and the outgoing port determined.
		Because of the switching employed, the MAC address of the destination device is read and the switch begins transmitting the packet before the total packet arrives in the switch.

	RAND Paul Baran: Distributed Communications - Introduction to Distributed Communications Network - On a Future System Development
		The switching process in any store-and-forward system is analogous to a postman sorting mail.
		What is envisioned is a network of unmanned digital switches implementing a self-learning policy at each node so that overall traffic is effectively routed in a changing environment--without need for a central and possibly vulnerable control point.
		If the postman sitting in the center of the United States received letters from San Francisco, he would find that letters from San Francisco arriving from channels to the west would come in with later cancellation dates than if such letters had arrived in a roundabout manner from the east.

		The Catalyst switch family spans the entire user application spectrum, from cost-conscious desktop and workgroup switches to multilayer-capable switches for scalable enterprise applications in the wiring closet, data center, and backbone.
		The Catalyst 2900 is well suited for smaller switched Fast Ethernet backbones or server farms, such as high- performance financial analysis centers or medical imaging environments that have collapsed backbones with Fast Ethernet switching at the center, or distributed backbones with Fast Ethernet switching in several locations.
		This switch platform is the first stackable switching architecture to deliver Layer 2 and Layer 3 functions in its stackable software for growing workgroup applications.

	RAND Paul Baran: Distributed Communications - Priority, Precedence, and Overload - Traffic Overload
		When the traffic volume arriving at the intermediate switching center from the many feed points is greater than the output circuit can handle, messages must be backlogged.
		Long-time intermediate storage is used at the switching nodes to improve high-cost long-line-circuit usage.
		A small amount of switching equipment can be safely shared by a large number of intermittent users.

	Nat' Academies Press, Cities and Their Vital Systems: Infrastructure Past, Present, and Future (1988)
		Electronic switching was introduced in the early 1960s when relays were used for connections, but the control function was a special-purpose, stored-program computer that could accommodate com- plex logic and software changes.
		Over the years, three technologies have been developed and used in switching: electromechanical, electronic, and digital systems.4 Because almost all new transmission systems are digital, the choice of digital switches is economical in telephone systems and is natural in telematics.
		The physical parts are the data transmission channels, the associated data switching systems, and the computers at terminals or nodes in the network.

	LAN Technology Scorecard
		Current industry jargon uses the term "Store and Forward Switching" for what used to be called bridging as opposed to "Cut Through Switching" and vendors of the two types will argue that one of these methods is superior to the other.
		The typical cut-through switch is clearly harder to build than a store-and-forward switch and was done that way on purpose to increase performance, but many customers feel a store and forward switch with good latency offers no significant performance disadvantage.
		Switched Ethernet: really the same as Ethernet as far as standards go; just the use of Ethernet to attach a switch (i.e., multiport bridge) to a client or smaller group of clients.

	Server Colocation
		Switched Ports greatly increase the viability of a network by utilizing store-and-forward switching technology to avoid congestion as well as Cyclic Redundancy Errors and collisions.
		Colocation with NYI is an outsourcing solution where the client places its server(s) in NYI's Data Center and the client is responsible for administration while NYI provides the cabinet space, bandwidth, routing, and electricity.
		Additionally, NYI utilizes 801.q tag switching to implement VLANs in order to physically separate clients networks from each other.

		Cut-through switching performs well relative to store-and-forward switching, even under heavy load.
		These include the use of FIFO input buffering in the crossbar switch, the deadlock-avoidance mechanism, cut-through routing, back-pressure for flow control, and multi-path routing.
		The deadlock-avoidance technique has an adverse effect on the performance of some topologies, but it seems to be the best alternative, given the goals and constraints of the AN1 design.

	TMCnet Article: "Real-Time Or Store-And-Forward: Consider Both IP Faxing Options" By Dennis Miga
		Country B is the switching hub that connects the managed bandwidth (X) between Country A and B with the international switched voice network (Y) that can reach the world.
		You'd either need to make a significant financial commitment for reserved bandwidth to many locations, or acquire bandwidth to a central switching point where the fax can be delivered over the final leg on the international switched voice network.
		If the environment is a resale or service provider where faxing habits of users cannot be controlled (for example, faxes are sent globally to many locations), the easy allocated bandwidth solution above doesn't work.

	Dialogic Announces T.37 Standard Compliance For Store-And-Forward Fax Over IP Networks
		Most Internet fax traffic still comes in the form of store-and-forward, however fax service providers will eventually deploy a combination of store-and-forward (T.37) and real-time (T.38) Internet fax.
		A fax is converted to a computer file and is then routed or "forwarded" across the Internet and delivered through the use of existing Internet mail gateways.
		Dialogic T.37 compliant products have already been implemented in and are supported by many of the leading Internet fax solutions.

	Inter-related switching, activity compression and demand assignment - Patent 4009344
		Each module (switch center) is organized to provide varied local and toll call connections, activity compression on a block basis and TDM digital signal switching on a block (store and forward) basis.
		Other objects are to provide modular "store and forward" digital switching centers, for operating hierarchically in stations covering a variety of "use-interface" areas relative to access nodes of a TDMA principal trunk facility, and a method of operating a network of such stations.
		Thus, burst length assignments of "east coast" centers in a continental United States network, can be progressively shortened with the approach of regional "sleeping" hours (11 P.M. - 6 A.M., EST), while assignments of "mid-west" and "west coast" centers are progressively lengthened.

		Although the switch normally tries to configure itself for the best possible performance and compatibility, you can manually disable features like cut-through switching in favor of store-and-forward on a port-by-port basis.
		I tested the switch's autoconfiguring por ts by throwing 4- and 16-Mbps connections, hub-based connections, workstation-based connections, and full- and half-duplex c onnections at it.
