Abstract

Claims (22)

1. In a network traffic capture/replay system operable to capture, in packet capture files, traffic between or among at least one initiator and at least one responder, wherein the network traffic comprises transactions and sessions, wherein the network traffic capture/replay system is further operable to scale or replay actual or simulated network traffic for load testing or other purposes, a method comprising:

extracting from the network traffic and scaling a plurality of sessions, while maintaining session integrity, session content, and session scalability to enable accurate replay,

enabling asymmetrical scaling, wherein a client is cloned to generate a desired traffic load, without cloning the server, to enable scaling of a client portion of transactions without cloning or scaling a server portion of transactions,

enabling complex scaling, wherein a captured packet contains control sessions that control dependent sessions,

wherein for each control session that is scaled, an additional stream session is scaled, and for each stream session that is scaled, an additional control session is scaled, such that when a complex session is scaled, a given interrelationship between a given control session and corresponding dependent sessions is preserved,

enabling traffic shaping, wherein the traffic shaping comprises parsing, categorizing and associating protocols associated with a packet capture file, and

enabling port mapping, wherein the port mapping comprises, prior to loading a packet capture file for replay, assigning source ports to each session, to enable application source ports to be subsequently examined to determine which payloads are associated with a particular session, and such that each payload has its own port.

2. A network traffic capture/replay system operable to capture, in packet capture files, traffic between or among at least one initiator and at least one responder, wherein the network traffic comprises transactions and sessions, wherein the network traffic capture/replay system is further operable to scale or replay actual or simulated network traffic for load testing or other purposes, the system comprising:

means for extracting from the network traffic and scaling a plurality of sessions, while maintaining session integrity, session content, and session scalability to enable accurate replay,

means for enabling asymmetrical scaling, wherein a client is cloned to generate a desired traffic load without cloning the server, to enable scaling of a client portion of transactions without cloning or scaling a server portion of transactions,

means for enabling complex scaling, wherein a captured packet contains control sessions that control dependent sessions,

wherein for each control session that is scaled, an additional stream session is scaled, and for each stream session that is scaled, an additional control session is scaled, such that when a complex session is scaled, a given interrelationship between a given control session and corresponding dependent sessions is preserved,

means for enabling traffic shaping, wherein the traffic shaping comprises parsing, categorizing and associating protocols associated with a packet capture file, and

means for enabling port mapping, wherein the port mapping comprises, prior to loading a packet capture file for replay, assigning source ports to each session, to enable application source ports to be subsequently examined to determine which payloads are associated with a particular session, and such that each payload has its own port.

3. A computer program code product executable in a network traffic capture/replay system comprising at least one computer that is operable to capture, in packet capture files, traffic between or among at least one initiator and at least one responder, wherein the network traffic comprises transactions and sessions, wherein the network traffic capture/replay system is further operable to scale or replay actual or simulated network traffic for load testing or other purposes, the computer program code product comprising computer-readable computer program code stored on a computer-readable storage medium, the computer program code product further comprising:

computer program code means executable by the computer to enable the computer to extract from the network traffic and scaling a plurality of sessions, while maintaining session integrity, session content and session scalability to enable accurate replay,

computer program code means for enabling the computer to execute asymmetrical scaling, wherein a client is cloned to generate a desired traffic load, without cloning the server, to enable scaling of a client portion of transactions without cloning or scaling a server portion of transactions,

computer program code means executable by the computer to enable the computer to execute complex scaling, wherein a captured packet contains control sessions that control dependent sessions,

wherein for each control session that is scaled, an additional stream session is scaled, and for each stream session that is scaled, an additional control session is scaled, such that when a complex session is scaled, a given interrelationship between a given control session and corresponding dependent sessions is preserved,

computer program code means executable by the computer to enable the computer to execute traffic shaping, wherein the traffic shaping comprises parsing, categorizing and associating protocols associated with a packet capture file, and

computer program code means executable by the computer to enable the computer to execute port mapping, wherein the port mapping comprises, prior to loading a packet capture file for replay, assigning source ports to each session, to enable

application source ports to be subsequently examined to determine which payloads are associated with a particular session, and such that each payload has its own port.
