Many monitoring and analysis tools are not designed, in the hardware or software, for handling traffic with certain protocols, labeling, or encapsulation. This could be because the analysis tool was not originally intended for use in environments with certain protocols, or the hardware is not able to handle certain protocols, such as VLAN tagging where some NICs and/or Switches either cannot handle any VLANs or can handle only a very limited number of VLANs.
VSS Monitoring's Protocol Slicing feature set provides the user with the ability to choose removal of a specific protocol header, such as GTP header, MPLS label, or VLAN tag/tags. By stripping these from the packets sent out the monitor ports, this removes the burden of handling these from the monitoring and analysis tools. VSS' aggregation, filtering, and load balancing can then be performed on the stripped packets.
Protocol stripping is available on the Advanced and Expert editions of the Distributed Traffic Capture Systems™ (DTCS).
*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.
