  • Correlation of performance monitoring records for logical end points within a protected group
    Patent number: 9258202
    Abstract: A network system comprising logical work and protect Connection Termination Points. Performance Monitoring (PM) records are provided by generating for each work Connection Termination Point (CTP) a work bit vector and a protect bit vector. The work bit vector keeps track of severely errored seconds (SES) occurrences at the work CTP only when the work CTP is selected. The protect bit vector keeps track of severely errored seconds (SES) occurrences at the protect CTP only when the protect CTP is selected. Processing the work bit vector and the protect bit vector provides accurate PM records.
