Method and system for packet size management

A network device comprising:

• a communication interface;
• a memory, wherein the memory stores instructions;
• and
• a processor, wherein the processor executes the instructions to:
• receive a request to provide a packet size service, wherein the network device is of an application service layer network;
• obtain, in response to receipt of 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;
• calculate, 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;
• validate the payload size with one or more third network devices in a network path between the end device and the second network device;
• transmit, via the communication interface to the end device based on successful validation, a first message that includes the payload size;
• and
• transmit, via the communication interface to the second network device based on successful validation, 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.

A non-transitory computer-readable storage medium storing instructions executable by a processor of a network device, which when executed cause the network device to:

• receive a request to provide a packet size service, wherein the network device is of an application service layer network;
• obtain, in response to receipt of 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;
• calculate, 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;
• validate the payload size with one or more third network devices in a network path between the end device and the second network device;
• transmit to the end device based on successful validation, a first message that includes the payload size;
• and
• transmit to the second network device based on successful validation, 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.
