But the TCAM has limited space for rules and can become easily exhausted. By migrating rules to other visibility nodes in the visibility fabric, the techniques introduced here allow the TCAM to be virtually extended across multiple visibility nodes. More specifically, upon receiving a data packet at an ingress port, the ingress visibility node can tag the data packet with an identifier based on which ingress port received the data packet. The ingress visibility node can then determine, based on the identifier, whether the data packet should be filtered using a rule stored in the TCAM of the ingress visibility node or a rule stored in the TCAM of some visibility node in the visibility fabric."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Filtration of network traffic using virtually-extended ternary content-addressable memory (TCAM)","description":"Ternary content-addressable memory (TCAM) of an ingress appliance in a visibility fabric may include rules for filtering traffic received by the ingress appliance.
