Inter-process networking for many-core operating systems

A method comprising:

• sending, via a first host-area network that connects a plurality of processes for a first host, a communication from a first computing process with a first network stack and a first internet protocol address to a second computing process with a second network stack and a second internet protocol address;
• determining, by an authentication component of the second network stack, that the communication is authorized;
• accepting, by the authentication component of the second network stack, the communication in response to determining that the communication is authorized;
• moving the second computing process from the first host to a different host while retaining the same second internet protocol address;
• and
• accessing, subsequent to the moving, network resources associated with the second computing process via the second network stack and the second internet protocol address.

A system comprising:

• one or more processors;
• a memory, coupled to the one or more processors, storing a first process, executing on the one or more processors, the first process including:
• a lightweight network stack and an internet protocol address that receives inter-process communications via a host-area network;
• a firewall component of the lightweight network stack that accepts the inter-process communications based in part on one or more of filtering rules, firewall rules, or authentication data;
• and
• a mobility component of the lightweight network stack that moves the first process from a first host to a second host via a gateway process, wherein the first process retains the same internet protocol address subsequent to moving from the first host to the second host via the gateway process.
