For example, an application can communicate with a targeted device based on application specified schedule, latency, jitter, error rate, throughput, level of security, and cost requirements. Exemplary system 150 supports mechanisms to manage QoS in an end-to-end fashion. System 150 supports use cases that require application 156 to specify on-demand E2E QoS requirements. On-demand E2E QoS requirements may include reachability schedule (e.g., when the application requires that a targeted M2M/IoT device be reachable to service its SL requests), E2E latency, E2E throughput, E2E jitter, E2E error rate, E2E security level, or E2E cost of communication, among other things. System 150 includes Internet of Things (IoT) servers (e.g., IoT server 152), IoT gateways (e.g., IoT gateway 151), and devices (e.g., IoT field device 153 or IoT device 154) interconnectedto one another via a diverse combination of local area and wide area underlying networks (e.g., 3GPP 161, broadband Ethernet 162, Wi-Fi 163, or 6LoWPAN 164). Hosted on the servers and gateways are instances of IoT SLs (e.g., IoT SL 166 or IoT SL 165). Hosted on the devices in the field as well as the devices in the backend are IoT applications (e.g., IoT device application 155 and IoT application156) that communicates with one another. For example, E2E communication between a patient's IoT sensor or actuator and a backend patient monitoring application. System 150 further includes a service layer connection manager (SLCM) function (e.g., SLCM 157 or SLCM 158), an application connection manager (ACM) function (e.g., ACM 159 or ACM 160) and an underlying network connection manager (UNCM) function (e.g., UNCM 167, UNCM 168, or UNCM 169). Together the SLCM, ACM, and UNCM functions interact with one another to more intelligently manage and configure the end-to-end underlying network QoS and connectivity of IoT devices, gateways, servers, and applications in support of E2E QoS.
