Measuring link performance using multiple radio access networks

摘要

Technology for measuring link performance using multiple radio access networks (RANs) is described. Data packets of a flow can be received, at a mobile node via a first connection with the mobile node with a first RAN. An active measurement can be initiated when a Real-time Traffic Flow Measurement (RTFM) triggering condition occurs. A second connection can be formed with the mobile node with a second RAN. Selected packets of the flow can be received for the active measurement using the first RAN and using the second RAN. An RTFM execution event can be communicated to a virtual access network (VAN) to move the flow from the first RAN to the second RAN when the active measurement of the selected packets is received via the second RAN is greater than a selected threshold value.

1. A mobile node for measuring link performance using multiple radio access networks (RAN), having computer circuitry configured to:
receive data packets of a flow at the mobile node via a first connection with the mobile node with a first RAN; initiate an active measurement when a Real-time Traffic Flow Measurement (RTFM) triggering condition occurs; form a second connection with the mobile node with a second RAN; receive selected packets of the flow for the active measurement using the first RAN and the selected packets of the flow using the second RAN; and communicate an RTFM execution event to a virtual access network (VAN) to move the flow from the first RAN to the second RAN when the active measurement of the selected packets received via the second RAN is greater than a selected threshold value, wherein the RTFM execution event is determined by at least iteratively increasing a packet counter for each packet received from the second RAN before the receipt of the packet from the first RAN.
