Abstract: A system comprises a frame parser and lookup engine operable to receive an incoming data frame, extract control data from payload data in the data frame, and using the control data to access a memory to fetch a plurality of instructions, a destination and tag management module operable to receive the fetched instructions and execute the instructions to transform the data frame control data, and an assemble module operable to assemble the transformed control data and the payload data.

Abstract: A single-ended Ethernet management system and method are provided. The system enables a user to provision and monitor an Ethernet interface, as well as to detect and isolate faults, from a single end. The method may be executed on the system to provide Ethernet services from a first end to a second end. After the Ethernet service is established, the method monitors the service from the first end to detect an occurrence of a fault and to identify service degradation issues. If a fault occurs, the method automatically executes a fault isolation procedure to isolate a location of the fault between the first and second ends. In addition, the method may categorize one or more potential causes for the fault based on fault location or type.

Abstract: A system and method for connection performance analysis are provided. In one example, the method is for performing an end-to-end analysis of a connection coupling two service demarcation points in a network, where each of the service demarcation points includes a test traffic injector and a test traffic monitor. The example method includes injecting test traffic into the connection using the test traffic injector of one of the service demarcation points. A loopback of the test traffic received by the other service demarcation point via the connection is performed to return the traffic to the originating service demarcation point. The traffic received by the originating service demarcation point via the connection is monitored to identify the looped back test traffic.

Abstract: Provided are a system and method for many-to-many layer 2 aggregation for SONET paths in a communications environment. In one example, the method includes receiving the data unit from either a layer 2 mapped data port or a SONET path, and classifying the data unit based on information within the data unit to identify which one of multiple logical flows is associated with the data unit. Each of the logical flows connects a data port with a SONET path and vice versa, and the data ports and SONET paths do not have a one-to-one correspondence. The data unit is directed to an outgoing SONET path associated with the logical flow if the data unit was received from the data port and to an outgoing data port associated with the logical flow if the data unit was received from a SONET path.
