Abstract: Systems, devices and methods for improving network performance are disclosed. In particular, in one embodiment, a method of processing data packets in an electronic network is provided. The method includes receiving data packets at a receive stack of an electronic network device and creating a first packet from at least a portion of each of the set of data packets. The first packet includes an indicator that the first packet is a first packet type. Additionally, the method includes passing the first packet to one of a bridge and IP layer of the receive stack. A first packet inhibitor at the one of the bridge and IP layer is bypassed upon recognizing the first packet as a first packet type. The first packet is routed to a transmit stack of the electronic network device from the one of the bridge and IP layer.

Abstract: An apparatus and method for expeditiously steering a received communication (e.g., packet, cell, frame) to one or more communication streams. When a new communication stream is opened on a network interface circuit or other Primary Point of Attachment (PPA), the protocol to which the stream is bound is used as a Service Access Point (SAP). A hierarchy of SAP nodes (e.g., a binary tree) is constructed, with each node corresponding to a unique SAP. Each node includes its corresponding SAP value, a count of the number of communication streams bound to the associated protocol, and a reference to those streams. When a communication is received, its SAP is extracted and the hierarchy is searched for a matching node. The communication is then forwarded to each referenced stream.

Abstract: A system and method for improving the efficiency with which data communications are passed through a protocol stack. Protocol layer modules within a protocol stack built upon the Streams framework are modified to establish tight embraces between adjacent modules. A tight embrace may be established by passing from one, upper, protocol layer module to its adjacent lower protocol layer module a pointer or reference to the upper module's functionality (e.g., rput) for reading a data communication into the upper module from the lower module. Similarly, the lower module passes the upper module a pointer or reference to its functionality (e.g., wput) for writing a data communication into the lower module from the upper module. After a tight embrace is established, the protocol layer modules can directly invoke each other's functionality, without incurring the overhead associated with the Streams framework's “canputnext” and “putnext” messages.
