Abstract
Official abstract text for this publication.
A system includes a memory and a processor communicatively coupled to the memory. The processor, in response to determining that a first number of transmissions over a first link with a first frequency has failed, selects a second link with a second frequency for transmission. The second frequency is lower than the first frequency. The processor also, in response to determining that a second number of transmissions over the second link has failed, one or more of (i) stop the transmissions over the second link or (ii) begins transmissions over a third link with a third frequency. The second number is greater than the first number.
First claim
Opening claim text (preview).
We claim: 1 . A system comprising: a memory; and a processor communicatively coupled to the memory, the processor configured to: in response to determining that a first number of transmissions over a first link with a first frequency has failed, select a second link with a second frequency for transmission, wherein the second frequency is lower than the first frequency; and in response to determining that a second number of transmissions over the second link has failed, one of (i) stop the transmissions over the second link or (ii) begin transmissions over a third link with a third frequency, wherein the second number is greater than the first number. 2 . The system of claim 1 , wherein the first number is one. 3 . The system of claim 1 , wherein selecting the second link for transmission is further in response to determining that the second link is available before the third link. 4 . The system of claim 1 , wherein selecting the second link for transmission is further in response to determining that the second link is available before the first link. 5 . The system of claim 1 , wherein selecting the second link is based on a quality of service for the first number of transmissions. 6 . The system of claim 1 , wherein the first frequency is 60 gigahertz. 7 . The system of claim 6 , wherein the second frequency is 5 gigahertz, 6 gigahertz, or 2.4 gigahertz. 8 . The system of claim 1 , wherein selecting the second link is further in response to a determination that the first link broke. 9 . The system of claim 1 , wherein the processor is further configured to retry a transmission over the first link in response to a determination that a prior failed transmission over the first link was caused by packet collision.
