Message communication techniques

An apparatus comprising:

• a processor;
• logic to receive a network protocol and to perform media access control, filtering, and buffering on the network protocol unit;
• and
• a physical message engine associated with a virtual message transmit engine, wherein
• the virtual message transmit engine is associated with a virtual message receive engine;
• the virtual message transmit engine is to request the physical message engine to transmit a request to send message to the virtual message receive engine;
• the virtual message transmit engine is to request the physical message engine to transmit the network protocol unit;
• and
• the physical message engine is to transmit content of the network protocol unit, using at least one segment, in response to a request from the virtual message transmit engine, to a memory region associated with the virtual message receive engine, the request identifying the virtual message receive engine and independent of specification of a physical memory address of the memory region.

A system comprising:

• a storage device;
• a network interface to receive a network protocol unit;
• a first message engine;
• and
• a second message engine, wherein:
• the first message engine is associated with a virtual message transmit engine,
• the virtual message transmit engine is associated with a virtual message receive engine;
• the second message engine is associated with the virtual message receive engine;
• the virtual message transmit engine is to request the first message engine to transmit a request to send message to the virtual message receive engine;
• the virtual message transmit engine is to request the first message engine to transmit content of the network protocol unit;
• and
• the first message engine is to transmit content of the network protocol unit using at least one message to a memory region associated with the virtual receive message engine, in response to a request from the virtual message transmit engine, the request from the virtual message transmit engine identifying the virtual message receive engine and independent of specification of a physical memory address of the memory region.
