Lotus Notes
Lotus Notes is a client/server collaborative application that provides email, instant messaging, calendar, resources, and file sharing. RiOS provides latency and bandwidth optimization for Lotus Notes 6.0 and later traffic across the WAN, accelerating email attachment transfers and server-to-server or client-to-server replications.
RiOS saves bandwidth by automatically disabling socket compression, that makes SDR more effective and saves bandwidth by decompressing Huffman-compressed attachments and LZ-compressed attachments when they’re sent or received and recompressing them on the other side. This allows SDR to recognize attachments that have previously been sent in other ways (such as over CIFS, HTTP, or other protocols), and also allows SDR to optimize the sending and receiving of attachments that are slightly changed from previous sends and receives.
To use this feature both the client-side and server-side appliances must be running RiOS 5.5.x or later. To enable optimization of encrypted Lotus Notes connections, both the client-side and server-side appliances must be running RiOS 7.0.
Enabling Lotus Notes provides latency optimization regardless of the compression type (Huffman, LZ, or none).
Before enabling Lotus Notes optimization, be aware that it automatically disables socket-level compression for connections going through SCC that have this feature enabled.
You can display and modify Lotus Notes optimization settings for the selected optimization policy on the Protocols Lotus Notes page.

Description
Enable Lotus Notes Optimization
Enables Lotus Notes optimization. By default, Lotus Notes optimization is disabled.
Enable on the client-side appliance to provide latency and bandwidth optimization for Lotus Notes 6.0 and later traffic across the WAN. This feature accelerates email attachment transfers and server-to-server or client-to-server replications. By default, Lotus Notes optimization is disabled.
Lotus Notes Port
On the server-side appliance, specify the Lotus Notes port for optimization. Typically, you don’t need to modify the default value 1352.
Optimize Encrypted Lotus Notes Connections
Enables Lotus Notes optimization for connections that are encrypted. By default, encrypted Lotus Notes optimization is disabled.
Perform these steps:
•  Configure an alternate unencrypted port on the Domino server to accept unencrypted connections in addition to accepting connections on the standard TCP port 1352. If the standard port is not configured to require encryption, you can use it instead of configuring an alternate port.
•  Select the Optimize Encrypted Lotus Notes Connections check box on both the client-side and server-side appliances.
•  Specify the alternate unencrypted port number on the server-side appliance.
•  Click Apply on both the client-side and server-side appliances.
•  Import the ID files of the servers for that you want to optimize the connections on the server-side appliance.
 
•  Under Encryption Optimization Servers, choose Add Server. Either browse to a local file or specify the server ID filename to upload from a URL. Specify the password for the ID file in the password field. If the ID file has no password, leave this field blank. Click Add.
•  The server ID file is usually located in
C:\Program Files\IBM\Lotus\Domino\data on Windows servers.
•  (Optional, but recommended unless another WAN encryption mechanism is in use.) Enable secure peering to create a secure inner channel between the client-side and server-side appliances.
•  Click Save on both the client-side and server-side appliances.
•  Restart the optimization service on both the client-side and server-side appliances.
After the connection is authenticated, the server-side appliance resets the connection of the Notes client, but maintains the unencrypted connection with the Domino server on the auxiliary port. The Notes client tries to establish a new encrypted connection, that the server-side appliance intercepts and handles as if it were the Domino server.
The server-side appliance (acting as the Domino server) generates the necessary information used to encrypt the connection to the Notes client. The result is an encrypted connection between the Notes client and server-side appliance. The connection is unencrypted between the server-side appliance and the Domino server.
Unencrypted Server Port
Specify the alternate unencrypted port number on the server-side appliance. You must preconfigure this port on the Domino server. If the standard port (typically 1352) doesn’t require encryption, you can enter the standard port number.
Encryption optimization servers
You can add encryption optimization servers for Lotus Notes.
