Use of Nagle Algorithm

Problem:

• Product Name: VisiBroker
• Product Version: 5.x and above
• Product Component: Connection Management
• Platform/OS Version: all

How to use Nagle algorithm with VisiBroker on Server/Client-side ORB when there is congestion?

Resolution:

Using the following VisiBroker properties to enable or disable the Nagle algorithm:

• Server-side ORB: vbroker.se.<se_name>.scm.<scm_name>.connection.tcpNoDelay
• Client-side ORB: vbroker.ce.iiop.connection.tcpNoDelay

When set to "true", the network connections will send data immediately. When set to "false", the network connections will send data in batches, as the buffer fills.

Note: The Nagle algorithm is used to automatically concatenate a number of small buffer, messages; this process (called nagling) increases the efficiency of a network application system by decreasing the number of packets that must be sent.
