Systems and methods for providing a back pressure free interconnect

A method, comprising:

• receiving, by a first interface, transactions from a plurality of agents;
• for each agent of the plurality of agents, assigning, by control logic, a data storage limit on an amount of data storage space in one or more buffers in a communication fabric that may be used by outstanding transactions to an initial amount of data storage space;
• and
• limiting, by control logic, a number of outstanding transactions for each of the plurality of agents based on a respective data storage limit;
• and
• reassigning, by control logic, the data storage limit of a first agent of the plurality of agents to an amount of data storage space different from the initial amount of data storage space, in response to determining a bandwidth requirement changes for the first agent.

A non-transitory computer readable storage medium storing program instructions, wherein the program instructions are executable by a processor to:

• receive transactions from a plurality of agents;
• for each agent of the plurality of agents, assign a data storage limit on an amount of data storage space in one or more buffers in a communication fabric that may be used by outstanding transactions to an initial amount of data storage space;
• and
• limit a number of outstanding transactions for each of the plurality of agents based on a respective data storage limit;
• and
• reassign the data storage limit of a first agent of the plurality of agents to an amount of data storage space different from the initial amount of data storage space, in response to determining a bandwidth requirement changes for the first agent.
