MONITORING IN SWITCH NETWORKS
First Claim
1. A method for remote monitoring of traffic in a network, comprising:
- tapping off traffic data from a first port;
routing the traffic data from the first port to a second port through one or more wide ports;
adaptively selecting one or both of the first port and the second port;
converting a protocol of the traffic data at the selected port; and
providing the traffic data at the second port for analysis.

Abstract
Monitoring in switch networks is disclosed. Ports in a switch may include monitoring circuitry and a monitoring tap which allows traffic data to be diverted for monitoring prior to any significant transformation of the traffic by the regular port logic. Furthermore, the monitoring circuitry can receive signaling and convert it for subsequent analysis by a protocol analyzer. The ports and paths in the switch network can be configured to create monitor paths to enable diverted traffic data to be passed through the network to locations where a protocol analyzer can be easily attached. With wide bandwidth ports, there is no disruption to the system. Because only a copy of the data is routed to the analyzer, there is no change to the original signal path and latency is identical with or without the analyzer.

11. A switch for remote monitoring of traffic in a switch network, the switch comprising:
-
a crossbar switch core; a plurality of ports configured to be selectively connectable to the crossbar switch core, one or more of the ports comprising; a monitoring tap configured for diverting traffic data from the port, and monitor logic for enabling the port to be configured for monitoring; and a processor coupled to the crossbar switch core and the plurality of ports for receiving a configuration command through the crossbar switch core to configure one or more of the plurality of ports, the processor being adaptively selected for converting a protocol of the diverted traffic data. - View Dependent Claims (12, 13, 15, 16, 23, 35)

24. A switch network comprising:
-
a first switch having a first port, the first port being operable to divert traffic data to a wide bandwidth path; and a second switch operably coupled to the first switch through the wide bandwidth path, the second switch having a second port, the second switch being operable to communicate the diverted traffic data through the second port; one or both of the first switch and the second switch being adaptively selected to convert a protocol of the diverted traffic data. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 36)
