Event driven interface for a system for monitoring and controlling a data communications network

Claim 2

In a system which communicates a serial data stream having a characteristic pattern, said system including a control vector source for providing a control vector which describes said characteristic pattern and an event vector expert for analyzing an event vector which represents a plurality of occurrences of said pattern an Event Driven Interface, comprising: an n-bit address register having a first portion with n-1 bits and an second portion with one bit and an input to said second portion coupled to said data stream, for receiving a bit from said serial data stream, where n is a positive integer; an addressable memory having a plurality of data storage locations, each having a first portion with n-1 bits and a second portion with m bits, said memory having an n-bit address input coupled an output of said address register and having a data input coupled to said control vector source, for receiving said control vector to configure data stored in first and second ones of said data storage locations to represent a digital filter for said pattern, where m is a positive integer or zero; a feedback path from an output of said memory to an input of said register, for transferring said data from said first portion of said first one of said data storage locations in said memory to said first portion of said address register, for concatenation with said bit from said serial data stream to form an address for accessing said second one of said data storage locations of said memory; a counter coupled to an output of said memory, for counting when said second one of said data storage locations in said memory is accessed, forming said event vector.

Claim 17

In a system for which communicates a serial data stream having a characteristic pattern, said system including a control vector source for providing a control vector which describes said characteristic pattern and an event vector expert for analyzing an event vector which represents a plurality of occurrences of said pattern, a method for generating said event vectors, comprising the steps of: receiving a bit from said serial data stream in an n-bit address register having a first portion with n-1 bits and an second portion with one bit and an input to said second portion coupled to said data stream, where n is a positive integer; receiving said control vector to configure data stored in first and second ones of data storage locations to represent a digital filter for said pattern, in an addressable memory having a plurality of data storage locations, each having a first portion with n-1 bits and a second portion with m bits, said memory having an n-bit address input coupled an output of said address register and having a data input coupled to said control vector source, where m is a positive integer or zero; transferring said data from said first portion of said first one of said data storage locations in said memory to said first portion of said address register over a feedback path from an output of said memory to an Input of said register; concatenating said data from said feedback path with said bit from said serial data stream to form an address for accessing said second one of said data storage locations of said memory; forming said event vector by counting when said second one of said data storage locations in said memory is accessed.

Claim 18

In a system for which communicates a serial data stream having a characteristic pattern, said system including a control vector source for providing a control vector which describes said characteristic pattern and an event vector expert for analyzing an event vector which represents a plurality of occurrences of said pattern, a method for generating said event vectors, comprising the steps of: receiving a bit from said serial data stream in an n-bit address register having a first portion with n-1 bits and an second portion with one bit and an input to said second portion coupled to said data stream, where n is a positive integer; receiving said control vector to configure data stored in first and second ones of data storage locations to represent a digital filter for said pattern, in an addressable memory having a plurality of data storage locations, each having a first portion with n-1 bits and a second portion with m bits, said memory having an n-bit address input coupled an output of said address register and having a data input coupled to said control vector source, where m is a positive integer or zero; transferring said data from said first portion of said first one of said data storage locations in said memory to said first portion of said address register over a feedback path from an output of said memory to an Input of said register; concatenating said data from said feedback path with said bit from said serial data stream to form an address for accessing said second one of said data storage locations of said memory; forming said event vector by counting when said second one of said data storage locations in said memory is accessed.
