…Radio Access Network (RAN) transport. The packet-bound IWF packetizes and encapsulates TDM data into either Ethernet frames or pseudowires, and forwards the data to the metro Ethernet or IP/MPLS packet network. The TDM-bound IWF extracts TDM data from the pseudowires or Ethernet frames and recreates…

…traffic management enables Gigabit Ethernet and 10Gigabit Ethernet ports and links to accommodate hundreds of individual services and ensures that Service Level Agreement (SLA) requirements for throughput, latency, jitter, and loss are met even under heavy traffic load conditions. These QoS mechanisms include…

…management aspect of SLA failures. SLA failures can be caused by link failures, such as a failing optical transceiver resulting in partial packet loss, or a service transport failure, such as a software failure leading to incorrect forwarding tables. Fault Notification Once detected by the network element…

…against Ethernet port failure and link failure between an adjacent pair of Ethernet ports, where the individual member links of a Link Aggregation Group (LAG) are physically routed over separate and diverse paths. To provide Ethernet resilience against forwarding failures, a set of Spanning Tree Protocols…

…switching capabilities such as Reconfigurable Optical Add/Drop Multiplexers (ROADMs). > Additional amplification is required to compensate the link budget loss caused by bulk DCM. This will require two line amplifier stages (instead of one), capital expenditure, and significant real estate and power consumption…

…routers lose service transparency. This loss is a result of the users-' inability to access SONET/SDH overhead bytes, the Data Communications Channel (DCC) that carries all the management bytes, and the inter-nodal communications used to determine network paths and link states. A traditional SONET/SDH solution…
