Systems and methods for adjusting the maximum transmission unit for encrypted communications

A system for adjusting the maximum transmission unit of a secure network communication to reduce network fragmentation, the system comprising:

• a means for establishing a session between a first computing device and a second computing device, the first computing device having a first network stack;
• a means for detecting, by the first computing device, a plurality of network packets of the session having an 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;
• a means for determining, in response to the detecting, by the first computing device, 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
• a means for altering the maximum transmission unit parameter of the first network stack to the determined setting.

A method for adjusting the maximum transmission unit of a secure network communication to reduce network fragmentation for a session, the method comprising the steps of:

• (a) establishing, by a remote access client of a computing device, a session with a gateway, the computing device having a network stack;
• (b) receiving, by the remote access client, from the gateway, a plurality of networks packets of the session;
• (c) detecting, by the remote access client, network packets of the plurality of network packets of the session having encrypted payloads, at least a first network packet of the detected network packets having a different size of encryption overhead than the one of a second network packet of the detected network packets;
• (d) determining, by the remote access client, in response to the detecting, a setting for a maximum transmission unit (MTU) parameter of the network stack to reduce a MTU size by a size of a largest encryption overhead of the plurality of network packets of the session;
• and
• (e) altering, by the remote access client, the MTU parameter of the network stack to the determined setting.
