Connections between the L4 switches are carried out, e.g., using Layer 2 switches. To this end, an intra-cluster routing entity of the switch maintains mapping information (e.g., in a database, or set of data structures) about connections that have been established by the individual switches within the cluster. In this approach, each host (itself a switch) preferably acts like a group of ports of the larger (big) switch. This obviates having each member host from having to maintain connections to many possible destinations. Rather, the intra-cluster routing entity maintains the information about which hosts (and its ports) are connected to which destinations, and the connections are re-used as necessary, even if connections on one side of the “big” switch ceased being used."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Layer 4 switching for persistent connections","description":"This disclosure provides for a Layer 4 switching approach wherein a set of L4 switches are organized into a cluster so as to act as a single (or “big”) Layer 4 switch.
