Tracing the Data Path
In Figure 102 - External Client Accessing Data from a Non-SLB Group, page 635, the client request
enters Alteon via ISP A or ISP B. ISP A is configured as real server 1 and ISP B is configured as real
server 2. A virtual server IP address is configured for each ISP and each domain. The virtual server
IP addresses for each ISP must be configured in the ISP's address range.
As shown in Figure 102 - External Client Accessing Data from a Non-SLB Group, page 635
, two
virtual server IP addresses (virtual server IP address 1 and virtual server IP address 2) are
configured for radware.com in each of the ISP's address ranges. Once Alteon responds with the
best virtual server IP address, all subsequent traffic from the clients to this domain is sent to the
same virtual server IP address, thereby passing through the same ISP.
External client request can be one of the following ways:
• External Client Accessing Data from a Non-SLB Group, page 635
• External Client Accessing Data from an SLB Group, page 636
External Client Accessing Data from a Non-SLB Group
In Figure 102 - External Client Accessing Data from a Non-SLB Group, page 635, a client request for
http://www.radware.com enters Alteon via an ISP. The non-SLB server (real server 3) can be
directly or indirectly connected to Alteon. A real server 4 is configured on the Alteon with the IP
address of real server 3. Real server 4 is added to a server group and that group is advertised in VIP
1 and VIP 2.
