Web Hosting Features
The RS 3000 provides features that support and improve performance for high-capacity web access:
Load balancing
– allows incoming HTTP requests to a company’s web site to be distributed across several physical
servers. If one server should fail, other servers can pick up the workload.
Web caching
– allows HTTP requests from internal users to Internet sites to be redirected to cached web objects on
local servers. Not only is response time faster, since requests can be handled locally, but overall WAN bandwidth usage
is reduced.
Session persistence
– In certain situations where load balancing is being used, it may be critical that all traffic for the
client be directed to the same physical server for the duration of the session; this is the concept of
session persistence
.
TCP persistence
–
a binding is determined by the matching the source IP/port address as well as the virtual
destination IP/port address.
SSL persistence –
a binding is determined by matching the source IP address and the virtual destination IP/port
address. Note that requests from
any
source socket with the client IP address are considered part of the same
session.
Sticky persistence –
a binding is determined by matching the source and destination IP addresses only. This
allows all requests from a client to the same virtual address to be directed to the same load balancing server.
Virtual private network (VPN) persistence –
for VPN traffic using Encapsulated Security Payload (ESP) mode
of IPSec, a binding is determined by matching the source and destination IP addresses in the secure key transfer
request to subsequent client requests.
IP persistence –
Used for L3 persistence of load balancing sessions.

Management Platforms
You can manage the RS 3000 using the following management platforms:
Command Line Interface (CLI)
– An Emacs editor-like interface that accepts typed commands and responds when
applicable with messages or tables. Use the CLI to perform the basic setup procedures described in
SNMP MIBs and traps
– The RS 3000 supports SNMP v1/v2 and many standard networking MIBs. The RS 3000’s
SNMP agent is accessed using integration software such as HP OpenView 5.x on Windows NT or Solaris 2.x, or
Aprisma SPECTRUM on Windows NT or Solaris 2.x. Setting up SNMP on the RS 3000 is described in
