Abstract
To prevent buffer overflow, a receiving entity may use credits to control the total amount of packets any single transmitting entity can forward. Once the assigned credits are spent, the transmitting entity cannot send data portions to the receiving entity until additional credits are provided. However, the logic in the receiving entity may be designed to manage a maximum number of credits that is less than the capacity of the buffer in the transmitting entity. For example, the receiving entity is designed to manage a maximum of eight credits but the buffer has room for twelve data portions. To use the buffer efficiently, the transmitting entity may identify when extra buffer storage is available and provide additional credits. In addition, the transmitting entity may control when the credits are provided such that the receiving entity is not allocated more credits that it was designed to manage.
