Abstract: Embodiments are directed to a method of implementing a packet capture ring. The packet capture ring includes a plurality of appliances, and the plurality of appliances includes a first appliance and a second appliance. The first appliance and the second appliance are both attached to a network tap, and the first appliance works as a master appliance. The master appliance ingests packets from the network tap, encapsulates the packets and forwards encapsulated packets in the packet capture ring. The method includes: detecting, by the second appliance, a failure of the first appliance; working, by the second appliance, as the master appliance; and removing, by the second appliance, the first appliance from a forwarding designation list.

Abstract: Embodiments provide a system and method for network tracking. By using packet capture applications having a flow identifier and a time stamper, one or more raw packets from one or more packet flows intercepted from a network can be tagged with a unique identifier and timestamp that can later be used to aggregate packet flows that have been analyzed by one or more capture applications. The unique identifier can relate to the network interface of the particular capture application and can also have an increasing value, where the increase in value can be monotonic. Later capture applications, while capable of generating secondary timestamps, can disregard those secondary timestamps for the primary timestamp of the first capture application in order to remove complications arising from latency issues.

Abstract: Embodiments are directed to a packet capture ring that provides a single network tap for packet capture and a series of processors (or appliances) for handling serialization and search request processing in a confederated and highly scalable manner. One such appliance (a “primary” appliance) maintains a tap port to the network. Each packet capture appliance has a locally attached repository that stores raw packets and a juxtaposed index that allows for retrieval of those packets. The primary appliance sends a single copy of encapsulated packets in opposite directions around the ring to its descendants. A designation is made across the system as to a “currently designated” appliance for servicing requests for indexing and storage of captured packets. This current designation shifts from appliance to appliance in the system, as a “previously designated” appliance has its storage capacity filled.

Abstract: A system and a method of operating the system, the system having a plurality of data receiving elements each receiving data packets from a data connection and from another receiving element and forwarding the two data packets to another receiving element in a predetermined order. If, at a point in time, only one data packet is received, a period of time is allowed to elapse, and if a second data packet is received, the two packets are output in the order. If not, the received data packet is output.
