Abstract:
1. A method for adjusting the maximum transmission unit of a secure network communication to reduce network fragmentation, the method comprising the steps of: (a) establishing a session between a first computing device and a second computing device, the first computing device having a first network stack; (b) detecting, by the first computing device, a plurality of network packets of the session having encrypted payloads, at least the first network packet of the plurality of network packets of the session having a different size of encryption overhead than the one of a second network packet of the plurality of network packets of the session; (c) determining, by the first computing device, in response to the detecting, a setting for a maximum transmission unit parameter of the first network stack to reduce a maximum transmission unit size by at least a size of a largest encryption overhead of the plurality of network packets of the session; and (d) altering the maximum transmission unit parameter of the first network stack to the determined setting.
