When Cisco explains their IOS SLB feature they often use the term connections. What constitutes a connection? I assume a connection is a TCP/UDP flow. The scenario in question - if one client IP is communicating with the virtual server IP would the load balancer ?balance? or distribute each new TCP flow/connection between the real servers?
TIA,

Ryan,
a connection is equal to 2 flows.
1 flow from client to server and 1 flow from server to client.
A flow is define by ip addresses (source & destination) , the protocol and the ports (source & destination).
A loadbalancer will loadbalance every new connections. You can use a sticky function to guarantee that connections belonging to the same session go to the same server.
Existing sticky methods are based on src ip, cookies, html header tag, ...
