Packet slicing is a traffic grooming technique traditionally done in a network analyzer at the monitoring application layer. It defines and discards part of a packet from the copy of traffic received by the analyzer, thereby allowing it to process and store more or only data of interest.
VSS Monitoring's vSlice extends the capability of packet slicing manyfold by allowing users to perform slicing at the traffic capture layer, anywhere in a network. Unlike competitive technologies, vSlice performs conditional packet slicing, which enables users to set slice points at different offsets for each packet as well as specify the types of traffic to be sliced, such as HTTP, SMTP, and the VoIP protocols RTP and RTCP.
Slice Closer to the Network
vSlice enables packet slicing to occur at the point of traffic capture, instead of at each analytical tool. As a result, vSlice can be used to ensure uniform and consistent packet slicing at one or many network segments. One or more instances of vSlice can extend the coverage of multiple analytical tools.
Greater Security
By acting at the point of capture, vSlice permits the removal of end-user identifying information at the beginning of the traffic capture process, reducing the risk of a privacy breach. vSlice helps ensure compliance with regulations mandating privacy best practices, such as the Payment Card Industry Data Security Standard (PCI DSS), which requires limiting access to cardholder information to a need-to-know basis.
vSlice can be applied on multiple ports of a VSS Monitoring traffic capture device, independent of other settings such as port mapping. vSlice is available at 10/100, Gigabit, and 10 GigE speeds, and on copper as well as fiber media. vSlice is the industry's most flexible packet slicing technology, and is part of VSS’ innovative Packet Optimization™ functionality suite, which includes ingress time and port stamping.
*Hardware-based modification of a packet by adding or stripping from it. Does not affect inline network traffic and can be enabled or disabled at will.
