The packet size service may calculate a payload size for packets that include application service data. The packet size service may inform an end device and an application service layer network of the calculated payload size. The packet size service may obtain quality of service information pertaining to an application service, and other information as a basis for the calculation. The packet size service may use a machine learning system to calculate the payload size. ## Claims ### Claim 1 A method comprising: receiving, by a first network device of an application service layer network, a request to provide a packet size service; obtaining, by the first network device in response to receiving the request, packet size information that includes quality of service (QoS) information pertaining to an application service, a network protocol of the application service, a data type of the application service, and a number of communication channels used for the application service; calculating, by the first network device based on the packet size information, a payload size for packets to be transmitted by at least one of an end device or a second network device of the application service layer network that provides the application service; validating, by the first network device, the payload size with one or more third network devices in a network path between the end device and the second network device; transmitting, by the first network device to the end device based on successfully validating, a first message that includes the payload size; and transmitting, by the first network device to the second network device based on successfully validating, a second message that includes the payload size, wherein the first message and the second message are transmitted before a session of the application service between the end device and the second network device begins. ### Claim 2 (depends on 1) The method of claim 1, further comprising: transmitting, during the session of the application service between the end device and the second network device, one or more packets using the calculated payload size. ### Claim 3 (depends on 1) The method of claim 1, wherein the packet size information includes a security requirement of the application service. ### Claim 4 (depends on 1) The method of claim 1, wherein the calculating further comprises: calculating, by the first network device, the payload size based on a machine learning system. ### Claim 5 (depends on 1) The method of claim 1, wherein the payload size does not conform to a size associated with the network protocol for the packets. ### Claim 6 (depends on 1) The method of claim 1, wherein the packet size information includes available resource information at the at least one of the end device or the second network device. ### Claim 7 (depends on 6) The method of claim 6, further comprising: determining, by the first network device based on the packet size information, whether application service data is pre-processed at the end device or at the second network device, and wherein at least one of the first message or the second message indicates a result of the determination. ### Claim 8 (depends on 1) The method of claim 1, wherein the application service layer network is a multi-access edge computing (MEC) network. ### Claim 9 A network device comprising: a communication interface;
