2. 2 © 1999, Cisco Systems, Inc. LocalDirector Version 3.1 Software Load balance SSLv3 via SSL Session ID Dispatch mode (No NAT) Flexible subnetting UDP support Buddy virtuals LD-QoS IP precedence levels 1 to 7 LUI 3.1 features

3. 31293_07F9_c1 © 1999, Cisco Systems, Inc. Sticky Based on SSL v3 Session ID Benefit: allows lD to perform sticky function in a proxy server environment Clients can be SSLv2 or SSLv3, servers have to be SSLv3 Command: sticky v_id minutes SSL

4. 41293_07F9_c1 © 1999, Cisco Systems, Inc. Dispatch Mode Manipulate mac addresses for load balancing rather than IP addresses Benefit: Support for applications with embedded IP addresses Increased application support Increased performance Idea Is That the Client Sends Packet to the Aliased Virtual on the Servers and the LD Will Intercept this Packet and Modify the dst-mac Address to Direct the Packet to Different Servers. The Servers Will Need to Support IP Address Aliasing. IP Address Aliasing VIP

6. 61293_07F9_c1 © 1999, Cisco Systems, Inc. UDP Support Load balance UDP applications such as DNS Increased multimedia application support

7. 71293_07F9_c1 © 1999, Cisco Systems, Inc. Associate virtuals with one another and apply a global sticky to both virtuals In other words, you could have a client fill up a shopping cart on a port 80 server through a port 80 virtual address, and “buddy” that with another virtual handling port 443 (SSL) traffic This also increases support for multimedia applications by allowing UDP and TCP virtuals to group together and apply sticky for clients arriving on either virtual Sticky Buddies

8. 81293_07F9_c1 © 1999, Cisco Systems, Inc. Packet Coloring on a Per-Virtual Basis Through interaction with QoS Policy Manager users will be able to set IP precedence bits for from virtual machines This is so other devices on the network can prioritize the data based on chosen QoS settings

9. 91293_07F9_c1 © 1999, Cisco Systems, Inc. LocalDirector and QoS The LD Can Set the QoS in the IP Header for the Packets Coming from the Server to the Internet. This Means that the Router or Switch Can Queue the Packets Depending Chosen QoS Settings. Mirrored Servers VIP QoS All Traffic Directed at VIP Is Given a IP Precedence Level of 5 Traffic Flowing Back to Client Receives QoS Policies for IP Precedence Level 5

10. 101293_07F9_c1 © 1999, Cisco Systems, Inc. LD Coloring Packets Value Proposition LD is an edge device that sees all traffic flowing from servers Bulk of data is from server to client LD can market IP precedence level based on a per virtual basis: IP Address, port, and source IP Address

Extensive Set of Tests  Response time of a server when a request for that URL is made  Response of a server when particular cookies are present in the request  Response of a server to particular user-agents (browser types)  Proper operation of any HTTP basic authentication scheme protecting access to that URL  Any redirection performed by the server when that URL is requested

16. 161293_07F9_c1 © 1999, Cisco Systems, Inc. Extensive Set of Tests (Cont.)  Length of the content returned by the server  Type of the content returned by the server  Status code returned by the server  Presence or absence of particular strings in the content returned by the server  Presence and content of any cookies returned by the server
