Classification: CPC H  G | IPC G  H

Claim 0:
1. An apparatus, comprising:
a first circuit configured to monitor first packets among traffic carried by one or more first directional lanes of a communication link established between a host having a root complex and one or more endpoint devices and determine header information for the first packets, wherein the communication link carries packets in a higher-level protocol over an underlying protocol and wherein the header information determined for the first packets comprises bus-device-function (BDF) properties;
a second circuit configured to detect second packets among traffic carried by one or more second directional lanes of the communication link based at least in part on the header information determined for the first packets; and
an analysis element processor configured to establish transaction metadata comprising properties of transactions on the communication link based at least on correlations among the first packets and the second packets, wherein the transaction metadata comprises transaction tags that organize individual transactions monitored on the communication link, associated endpoint addresses, transaction types, and the BDF properties.
