Abstract

Multiple channels of a multi-channel analyzer are allocated among multiple users such that each user can initiate and retrieve the results of separate diagnostic sessions or strategies. Each analyzer channel includes an input connection port, a trace buffer memory and logic circuitry. The input connection port is operably connected to a unique node in the communication network. A host processor assigns ownership of a unique set of analyzer channels to at least two users such that each user can initiate separate simultaneously established traces on the communication network. The logic circuitry monitors frame data on the connection port at each node in accordance with a set of instructions established by the user assigned to the analyzer channel for that node, and the traces are captured in response to the set of instructions such that each user retrieves only results of the analyzer channels assigned to that user.

Claims

1. A method for controlling the operation of at least three analyzer channels for analyzing a communication network, each analyzer channel including an input connection port, a trace buffer memory and logic circuitry, the method comprising:

operably connecting the input connection port of each analyzer channel to a unique node in the communication network;

using a host processor operably connected to each analyzer channel to assign ownership of a unique set of analyzer channels to at least two different users such that each user can initiate separate traces that are simultaneously established on the communication network;

using the logic circuitry to monitor frame data on the connection port at each node in accordance with a set of instructions established by the user assigned to the analyzer channel for that node; and

capturing traces in response to the set of instructions for each analyzer channel such that each user retrieves only the results of the analyzer channels assigned to that user.

2. A computer system for allocating control of analyzer channels of a multi-channel analyzer having at least three analyzer channels, each analyzer channel including at least an input connection port to a communication network, a trace buffer memory, and logic circuitry controlling selective write operations of traces from the input connection port to the trace buffer memory in response to a status condition, the system comprising:

a host processor;

a means for operably connecting the host processor to each logic circuitry of the multi-channel analyzer;

a computer program that implements directions input into the host processor, whereby the host processor communicates to each logic circuitry for selectively configuring and controlling the multi-channel analyzer for use by a plurality of users, and whereby the host processor selectively allocates control of at least one of the analyzer channels to one of the users in response to directions by the user, so that the user can initiate and retrieve results of an analyzer session simultaneously established with other analyzer sessions for different analyzer channels.

3. A method for controlling the operation of at least three analyzer channels for analyzing a communications network, each analyzer channel including at least an input connection port to a communication network, a trace buffer memory, and logic circuitry controlling selective write operations of traces from the input connection port to the trace buffer memory in response to a status condition, the method comprising the steps of:

operably connecting the input connection port of each analyzer channel to a unique node in the communication network;

using a host processor operably connected to each analyzer channel for allocating control of the analyzer channels to a plurality of users, so that each user can initiate and retrieve results of an analyzer session simultaneously established with other analyzer sessions;

using the logic circuitry of at least one of the analyzer channels to monitor data on the connection port of the at least one analyzer channel in accordance with directions by the user having control of the analyzer channel;

capturing traces on the at least one analyzer channel in accordance with directions by the user having control of the at least one analyzer channel; and

transmitting results of the analyzer session to the user.

4. A method for controlling the operation of a plurality of multi-channel analyzers, each multi-channel analyzer having at least three analyzer channels for analyzing a communications network, each analyzer channel including at least an input connection port to a communication network, a trace buffer memory, and programmable logic circuitry having instruction memory and controlling selective write operations of traces from the input connection port to the trace buffer memory in response to a status condition, the method comprising the steps of:

operably connecting the input connection port of each analyzer channel to a unique node in the communication network;

using a host processor operably connected to each multi-channel analyzer to select at least one multi-channel analyzer for use in an analyzer session;

using the host processor for allocating control of the analyzer channels to a plurality of users so that each user can initiate and retrieve results of an analyzer session simultaneously established with other analyzer sessions for different analyzer channels;

optionally and selectively assigning into mutually exclusive groups the analyzer channels allocated to any of the users, so that each group can be used for an analyzer session simultaneously established with other analyzer sessions for different groups;

optionally and selectively identifying a communication network cabling configuration mode used in a hardware installation to which a pair of allocated analyzer channels is connected and in accordance with directions by the user having control of the pair of analyzer channels;

programming at least one data capture strategy parameter into the instruction memory of the logic circuitry of an analyzer channel and in accordance with directions by the user having control of the analyzer channel;

optionally and selectively programming into the instruction memory of the logic circuitry of an analyzer channel and in accordance with directions by the user having control of the analyzer channel at least one parameter from the group consisting of parameters for prefiltering the amount and type of data captured and parameters for triggering;

using the logic circuitry of an analyzer channel allocated to the user to monitor data on the connection port of the analyzer channel in accordance with directions by the user;

capturing traces on the analyzer channel; and

transmitting results of the analyzer session to the user.
