	Synchronous optical networking - Wikipedia, the free encyclopedia
		The Synchronous optical network, commonly known as SONET, is a standard for communicating digital information using lasers or light emitting diodes (LEDs) over optical fiber as defined by GR-253-CORE from Telcordia.
		SONET differs from PDH in that the exact rates that are used to transport the data are tightly synchronized across the entire network, made possible by atomic clocks.
		This network loop will eventually see its own timing "float away" from any external SONET networks, causing mysterious bit errors, the source of which can be hard to find (unless the presence of the timing loop is detected).

	Computer networking - Wikipedia, the free encyclopedia
		Computer networking is the scientific and engineering discipline concerned with communication between computer systems.
		Networks, and the technologies needed to connect and communicate through and between them, continue to drive computer hardware, software, and peripherals industries.
		In 1968 Paul Baran proposed a network system consisting of datagrams or packets that could be used in a packet switching network between computer systems.

	RFC 4257 (rfc4257) - Framework for Generalized Multi-Protocol Label Switch
		We then examined optical path provisioning or signaling, considering the issue of what constitutes an appropriate label for TDM circuits and how this label should be structured; and we focused on the importance of hierarchical label allocation in a TDM network.
		In particular, where unsecure versions of network management protocols such as SNMP versions 1 and 2 were popular configuration tools in transport networks, the use of a control plane may significantly reduce the security risk of malicious and false assignment of network resources that could cause the interception or disruption of data traffic.
		MPLS Overview A major advantage of the MPLS architecture [1] for use as a general network control plane is its clear separation between the forwarding (or data) plane, the signaling (or connection control) plane, and the routing (or topology discovery/resource status) plane.
