Methods and apparatus for sharing and arbitration of host stack information with user space communication stacks

A method for setting system-wide parameters for communication stack coexistence devices, comprising:

• storing one or more system control parameters within a shared data structure, wherein the shared data structure is read-write for kernel space processes in a kernel space and is read-only for user space applications including one or more user space communication stacks;
• initializing a host communication stack at the kernel space based on the one or more system control parameters;
• and
• initializing at least one other communication stack based on the one or more system control parameters, wherein the other communication stack is either an other host communication stack or a user space communication stack;
• wherein the host communication stack and the at least one other communication stack are configured to share a common resource.

A non-transitory computer readable apparatus comprising a storage medium having one or more computer programs stored thereon, the one or more computer programs being configured to, when executed by a processing apparatus, cause a computerized apparatus to:

• request a tuple entry for a user space communication stack from a shared namespace registry, wherein the shared namespace registry includes a 3-tuple entry for a first user space communication stack, a 5-tuple entry for a second user space communication stack, and a 3-tuple entry for a host stack;
• determine whether the shared namespace registry is up-to-date and whether resources are available to support the tuple entry;
• and
• cause, in response to determining the shared namespace registry is up-to-date and resources are available to support the tuple entry, a registration of the tuple entry for the user space communication stack in the shared namespace registry.
