| | 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. | | | 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). | | | In general, a SONET Network that has been properly configured will never find itself in a timing loop, but it is sometimes hard to avoid this without sophisticated network management tools. |

| | 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. | | | Due to the complexity of some of the connection routing algorithms (high dimensionality, non-linear integer programming problems) and various criteria by which one may optimize a network, it may not be possible or desirable to run these algorithms on network nodes. | | | The basic tradeoff between the centralized and distributed approaches is that of complexity of the network elements versus that of the network management system (NMS). |
