Systems and methods are disclosed for determining a topology of a network comprising a plurality of intermediary devices and intermediary paths. One method includes transmitting probes having a TTL value with a destination set to a destination device; receiving, for each probe transmitted, a response including an IP address of a responding device; determining whether more than one responding device has responded to the probes; determining whether more than one responding device has been found for two previous transmissions of probes when more than one responding device has responded to the probes; and transmitting, for each more than one responding device, probes having a decreased TTL value with a destination set to one of the IP addresses of the more than one responding devices, when more than one responding device has been found for two previous transmissions.

A method, an apparatus, a computer-program product and a system for transmission of data packets are disclosed. A communication link between a first device and a second device is established in accordance with a transmission control protocol for transmission of a data packet between the first device and the second device. The communication link is monitored during transmission of the data packet from the second device to the first device. Based on the monitoring, at least a portion of a bandwidth available for transmission of an acknowledgement from the second device to the first device is adjusted. The acknowledgement indicates receipt of the data packet performing by the second device.

This application discloses a connection establishment method implemented in an end node of the connection. The method includes: obtaining transmission status information of at least two available paths, the transmission status information of each available path of the at least two available paths indicates transmission performance of the each available path, the at least two available paths corresponding to different types of networks; determining a better available path with better transmission performance, the better available path determined based on the transmission status information of the at least two available paths; and establishing the connection using a network corresponding to the better available path.

Methods and system for supporting multiple management interfaces using a network analytics engine. The network analytics engine can run on a core switch for performing data collection and monitoring of network traffic through the switch. The switch can receive a first list including a first set of network packet parameters for monitoring network traffic using certain monitoring criteria. Then, the switch can receive a second list including a second set of network packet parameters for monitoring network traffic in accordance using different monitoring criteria. The switch can generate a concatenated list including the first list and the single list to form a single set of packet parameters. Concatenation may be consistent with a determined sequential order and priorities assigned to the lists. The switch can be programmed with the concatenated list such that network monitoring is accomplished using both monitoring criteria, while only implemented a single concatenated list.

A system includes a first and at least one second processing circuit, a configuration engine, and a switch. The configuration engine stores a virtual link configuration for a plurality of virtual links, which indicates a priority and a predetermined network pathway for communicating data packets from the first processing circuit to the at least one second processing circuit. The configuration engine automatically assigns priority to a first virtual link of the plurality of virtual links based on at least one of latency or jitter. The switch receives a first data packet from the first processing circuit. A first virtual link identifier is extracted from the first data packet. A first priority and a first predetermined network pathway corresponding to the first virtual link identifier from the virtual link configuration are retrieved. The first data packet is transmitted along the first predetermined network pathway based on the first priority.

Systems, methods, and computer-readable media for annotating process and user information for network flows. In some embodiments, a capturing agent, executing on a first device in a network, can monitor a network flow associated with the first device. The first device can be, for example, a virtual machine, a hypervisor, a server, or a network device. Next, the capturing agent can generate a control flow based on the network flow. The control flow may include metadata that describes the network flow. The capturing agent can then determine which process executing on the first device is associated with the network flow and label the control flow with this information. Finally, the capturing agent can transmit the labeled control flow to a second device, such as a collector, in the network.

Techniques and architectures for measuring available bandwidth. A train of probe packets is received from a remote electronic device. A per-packet one-way delay (OWD) is calculated for at least two packets from the train of probe packets. An OWD threshold value is calculated based on the calculated OWD for the at least two packets from the train of probe packets. A packet pair is selected from the train of probe packets based on the per-packet OWD for each packet in the packet pair exceeding the OWD threshold value. An estimated available bandwidth is computed based on one or more transmission characteristics of the selected packet pair.

A data transaction processing system includes a quarantine system that delays messages configured to accept a delay before being processed by the data transaction processing system. During periods of heavy network traffic, the imposed delay reduces network congestion by distributing/load leveling messages according to available computing resources. Separating messages over time also reduces the processing latency of the data transaction processing system. Messages that are routed and delayed through the quarantine system may be executed at a better transactional value than other non-delayed messages.
