摘要： A method executed by a dynamic session key acquisition (DSKA) engine residing in a virtual environment includes receiving session decryption information extraction instructions that configure the DSKA engine to obtain session decryption information for at least one communication session involving a virtual machine and obtaining the session decryption information from the virtual machine in accordance with the session decryption information extraction instructions. The session decryption information includes cryptographic keys utilized by an application server instance in the virtual machine to establish the at least one communication session. The session decryption information obtained from the virtual machine is stored and provided to a network traffic monitoring (NTM) agent. The NTM agent utilizes the session decryption information to decrypt copies of encrypted network traffic flows belonging to the at least one communication session involving the virtual machine.

摘要： Systems and methods are disclosed for packet deduplication for network packet monitoring in virtual processing environments. Tap agents are installed and run with respect to network applications operating with virtual processing environments. These tap agents capture packet traffic associated within these network applications, and deduplication rules are applied so that duplicate packet capture is avoided at the tap agents themselves. In particular, deduplication rules are applied to tap agents where two network applications for which packets are being captured are talking to each other so that one of the tap agents is set to the designated agent for packet capture. Without this designation, packets captured at by the two associated packet agents would represent the same packet flow from both ends thereby leading to duplicate packet capture.

摘要： Systems and methods are disclosed for drop detection and protection with respect to packet monitoring in virtual processing environments. Tap agents monitor and capture packets from the network traffic associated with network applications running within these virtual processing environments. Sequence numbers are added in packet encapsulation before tap packets are forwarded to tool agents. The tool agents then use the sequence numbers to detect packet drops within the tap packets. After drop detection, the tool agents send drop detection messages to an agent controller, and the agent controller generates and sends reconfiguration messages to the tap agents based upon the drop detection messages. The tool agents can also send drop detection messages directly to the tap agents. The tap agents adjust their operations based upon the reconfiguration messages and/or the drop detection messages to reduce packet drops within subsequent tap packets communications.

摘要： Systems and methods are disclosed to forward packets not passed by criteria-based filters in packet forwarding systems. The disclosed embodiments include one or more Not Passed By Criteria (NPBC) filters that are defined for input ports along with one or more criteria-based filters, such as for example, Pass by Criteria (PBC) filters and/or Deny by Criteria filters (DBC), that forward packets not passed by these criteria-based filters. NPBC filters include, for example, Pass Unmatched PBC filters associated with PBC filters and configured to forward packets not passed by PBC filters and/or Pass Matched DBC filters associated with DBC filters and configured to forward packets not passed by DBC filters. Using one or more NPBC filters within the disclosed embodiments, packet data that is not being passed along to output ports by the criteria-based filters can be easily passed to one or more designated output ports.

摘要： Network tool optimizers for server cloud networks and related methods are disclosed. In part, master filters are defined to segregate and control user traffic, and user filters are defined to forward the user traffic to cloud-based network tools or tool instances. A master user interface and user interfaces for each user are provided so that the master filters and user filters can be defined and managed. A filter rules compiler within the cloud-based network tool optimizer then combines the master filters with the user filters, resolves conflicts in favor of the master filters, and generates filter engine rules that are applied to filter engines within the network tool optimizer for the cloud network. The filter engines then forward packets received at input ports for the network tool optimizer to output ports for the network tool optimizer that are coupled to network tools or tool instances within the cloud network.

摘要： A test system includes a radio frequency (RF) shielded chamber and an antenna array in the RF shielded chamber. The antenna array includes groups of antenna elements and power combiners. Each group of antenna elements is matched to a matching group of antenna elements by virtue of being coupled to a respective power combiner for both the group and the matching group. The antenna array is configured, by virtue of spacing apart the antenna elements by at least half of a wavelength of a test signal for testing a wireless device in the RF chamber, so that power delivered to output ports of the antenna array is substantially uniform regardless of where the wireless device is placed within the RF chamber.
