4. Globally enable compression.
5. Set the HTTP virtual service to used in the defined virtual server.
TCP Congestion Avoidance
Alteon uses an improved TCP congestion avoidance algorithm for maximum throughput. The
algorithm automatically adjusts the TCP congestion window size according to media and congestion
conditions, so no configuration is required.
FastView Licensing
FastView licenses are not available for Alteon version 29.
Radware's FastView Advanced Web Performance Optimization solution is available as a standalone
solution. For more information, see www.radware.com/Solutions/Enterprise/ApplicationNetworking/
ApplicationAcceleration.aspx.
Content-Intelligent Connection Management
Alteon supports connection management, which multiplexes client and server connections and
improves the throughput of SLB. It also helps the real server lower the need of establishing and
tearing down TCP connections.
Since Alteon acts as a client for the back-end servers, Alteon always tries to reuse previously
established SSL sessions. The SSL session reuse attempts are usually successful because the
back-end server recognizes Alteon as a client that connects repeatedly. SSL session re-use between
Alteon and the back-end servers helps lower the overhead involved in performing a full SSL
handshake.
In a connection managed environment, a pool of server connections is maintained for servicing
client connections. When a client sends an HTTP request, a server-side connection is selected from
the server pool and used to service the request. When the client request is complete, the server
connection is returned to the pool and the client connection dropped.
This feature only supports the HTTP and HTTPS protocols over TCP, and can work in conjunction with
SSL, caching, and compression. When used with back-end SSL (where SSL is used between Alteon
and the servers), it also reduces load on servers because fewer SSL handshakes are needed to be
performed by them.
The following example enables connection management for the HTTP and HTTPS protocol on virtual
Server 1:
>> Compression Browser Rule-List mybrwslist#
(Add a rule to the rule list)
>> Main# /cfg/slb/accel/compress/brwslist# ena
(Enable the browser List)
>> Main# /cfg/slb/accel/compress/on
>> Main# /cfg/slb/virt 1/service 80/http/comppol
(Define HTTP service)
>> HTTP Load Balancing# comppol myPol
(Associate the defined
compression policy)
