	Switching center - Wikipedia, the free encyclopedia
		A switching center is a node in a telecommunications Circuit switching network which is connected to either another switching center and/or to end user devices.
		Switching centers are aware of other centers and possible routes between them such that on demand a center can establish an optimal route for a demanded circuit.
		Compare packet switching networks which make some of these decisions for each packet of a data exchange.

	Lantronix Switching Tutorial: Server Switches, Congestion and Network Capacity
		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.
		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.
		If the switching bus, or switching components cannot handle the theoretical total of all ports the switch is considered a "blocking switch".

	Communication network with dynamic intraswitching - Patent 5523997
		When a mobile switching center 22 determines that the other of the two half-calls it is being asked to connect resides within its jurisdiction through PSTN 18, it routes a second communication path leg through interface 24 toward PSTN 18.
		Intraswitching refers to switching a communication path at a switching center which is remotely located from the place where the switching connection is defined.
		Even though mobile switching center 22 is not included in the communication path, it is still in signalling communication with user unit 16 and any other node of network 10 through communication links 32 and 34.

	Survey of Telephone Switching - Chapter 2
		The general toll switching plan as originally conceived called for one of the regional centers to be designated "National Center" with final trunk groups to and from all regional centers.
		A control switching point is a key switching location in the nationwide automatic switching network which may have some or all of the features indicated on Figure 2-5.
		That one higher ranking switching point to which an office is connected over a final group is called its "home" office; the dependent office is spoken of as "homing" on it.

	Arrangement for call forwarding in a mobile services switching center (US6167256)
		The mobile services switching center contains a call forwarding database which stores directory numbers of forwarding parties from each of which a set-up of a forwarded call is in progress.
		The call control of the mobile services switching center is arranged to check, prior to initiating call forwarding, whether a directory number of the forwarding party is included in the call forwarding database.
		the call control of the mobile services switching center is arranged, in response to the directory number of the forwarding party not being included in the call forwarding database, to insert the directory number of the forwarding party in the call forwarding database, and to continue the call forwarding.

	Storage Networking World Online - Best of Coumputerworld Storage Knowledge Center - SAN switching: Bigger is better
		There are two categories of chassis-based switches: port-dense switches, which have at least 64 ports, and director-level switches, which have at least 64 ports, as well as high-availability features.
		Most chassis-based switches have a minimum capacity of 64 ports that are contained in an enclosure to which additional ports can be added.
		"We've never used smaller switches, because of the problem that you have to connect smaller switches to other switches for switch-to-switch communication, and that's where you lose a lot of interconnect ports, so the availability of that is really bad," Kahlenberg says.

	Gateway History - The story on the growth of the main telecommunication switching system
		The model 30 was modified from its role of feeding the National Meteorological Center (NMC) computer model software to a support role in the automation of facsimile transmissions and the IBM 360 model 40's took on the task of communications with the NMC.
		The Washington communications center exchanged data with the main FAA Weather Message Switching Center in Kansas City, MO. Specially formatted data, surface observations and forecasts for many foreign locations were provided to the FAA through the FAA.
		Thus, there was an increase in the data exchange between the two centers and this required the Gateway to increase the Bracknell GTS link line speed to 9600 bps by 1987 and later to 14.4 Kbps to meet the exchange requirements.

	Data Center & Server Switching - Data Center Networks Blog Archives
		You may be wondering if there is anything to this “Data Center 3.0” thing beyond some clever marketing folks earning their paychecks.
		I have a beautiful slide deck highlighting the advantages of Cisco’s end-to-end data center strategy; the builds and animation are fantastic, the graphics superb, and of course my oratory is reminiscent of Lincoln’s Gettysburg address.
		So when someone claims, “Full Wire Rate Switching at all frame sizes’ they are implying that for each port there is a non-blocking data path through the switch port to port and that the forwarding engine has the capacity to do packet lookups, ACLs, QoS remarking, etc without slowing down the packet forwarding rates.
