Methods and systems for controlling transmission rates in networks

A non-transitory, machine readable storage medium having stored thereon instructions for performing a method, comprising machine executable code which when executed by at least one machine, causes the machine to:

• manage, at a target, a request to transmit (R2T) queue and an associated data credit counter;
• increment the data credit counter based on an allowed transfer rate;
• select an R2T packet from the R2T queue;
• determine if the R2T packet should be sent based on the data credit counter;
• send the R2T packet to an initiator when the R2T packet indicates data transfer less than the data credit counter;
• and
• decrement the data credit counter based on the R2T packet when the R2T packet is sent.

A system, comprising:

• a memory containing machine readable medium comprising machine executable code having stored thereon instructions;
• and
• a processor module coupled to the memory, the processor module configured to execute the machine executable code to:
• manage, at a target, a request to transmit (R2T) queue and an associated data credit counter;
• increment the data credit counter based on an allowed transfer rate;
• select an R2T packet from the R2T queue;
• determine if the R2T packet should be sent based on the data credit counter;
• send the R2T packet to an initiator when the R2T packet indicates data transfer less than the data credit counter;
• and
• decrement the data credit counter based on the R2T packet when the R2T packet is sent.
