Enterprise information facilities repeatedly monitor community site visitors to enhance efficiency, present higher buyer expertise, and establish threats. All these home equipment or instruments require solely a portion of the community payload to satisfy the monitoring necessities. Trendy Community Packet brokers use “Packet truncation” approach to optimize the processing of community site visitors which entails the removing of parts of community packets that aren’t wanted for evaluation.
Want for Packet Truncation
Cut back Storage: Community site visitors payload might be very giant (64 to 9216), and storing every thing will probably be costly. Packet truncation helps cut back the quantity of information that must be saved by eradicating irrelevant or redundant data from packets.
Cut back CPU Cycles: Truncated packets require much less processing to investigate, which may enhance the general velocity and efficiency of the instruments.
Simplify Evaluation: Community directors can simply establish community efficiency points extra rapidly and effectively since truncated packets have the related parts of the packet.
Enhance Safety: By eradicating delicate data from the payload, safety might be improved by limiting the publicity of confidential information.
Aviz Open Packet Dealer trade first Packet dealer resolution constructed on Open Networking NOS SONiC supporting truncation on commodity ASICs supporting wire-speed packet truncation. Open Packet dealer truncation has the next capabilities.
- Packet Truncation primarily based on customized offsets (48 bytes to 4094 bytes).
- VLAN tag insertion for truncated packets for various tooling functions.
- Load Steadiness throughout instruments for optimum processing
Packet Truncation or slicing will permit solely the user-defined byte from an incoming packet, and the remaining bytes are discarded. This helps in lowering the amount of information processed on the instrument port.

Packet Truncation helps cut back storage necessities, enhance evaluation, velocity up processing, and improve community safety. Open Packet Dealer from Aviz Aviz OPB improves price financial savings by offering prospects the selection of Open Networking HW SKUs supporting line-rate packet processing.
