Abstract:
1. A network device for managing communications, the network device comprising: a first counter operable to track CIR tokens, wherein the first counter is operable to increase the CIR tokens at a first rate; a second counter operable to track EIR tokens, wherein the second counter is operable to increase the EIR tokens at a second rate; logic in communication with the first counter and the second counter, wherein the logic is operable to determine whether there are EIR tokens in response to a determination that there are not CIR tokens, wherein the logic is further operable to command the second counter to decrement the EIR tokens in response to a determination that there are EIR tokens, and wherein the logic is further operable to communicate a data unit from the network device through a network in response to decrementing the EIR tokens.
