Abstract
A method of processing a frame received at a networked device having a port switch and a general-purpose processor. The method can include receiving frame information at the port switch, determining at least one port for the frame, and directing the received frame information based on the determined port(s).
Claims33
A method of processing a frame received at a networked device via a network, the device having at least one port switch and at least one general-purpose processor, the method comprising:
- receiving frame information transmitted over the network at the port switch;
- determining, at the port switch, at least one port for the received frame information;
- and
- directing the received frame information based on the determined port(s).
A method of processing a frame received at a networked device via a network, the device having at least one port switch, at least one dedicated hardware system, and at least one general-purpose processor, the method comprising:
- receiving IP (Internet Protocol) frames transmitted over the network at the port switch, the frames including identification of a TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) destination port;
- determining, at the port switch, the destination port for the received frames;
- and
- directing the received frames based on their, respective, destination ports, the directing comprising forwarding at least some of the frames to the general-purpose processor and forwarding at least some of the frames to the determined dedicated hardware system(s).
A port switch for use in a networked device, the network device also having at least one general-purpose processor, the port switch comprising electronics and instructions for causing the electronics to:
- receive frame information transmitted over the network;
- determine at least one port for the received frame information;
- and
- direct the received frame information based on the determined port(s).
A networked device, comprising:
- at least one general-purpose processor;
- one or more dedicated hardware systems;
- a network connection for receiving frames from remote networked devices;
- and
- a port switch that receives information from the frames received over the network connection, the port switch
- determining at least one port for at least some of the received frames, and,
- based on the determined ports, directing some of the frames to the general-purpose processor and directing some of the frames to the dedicated hardware systems.
A method of processing a frame received at a networked device via a network, the device having a port switch and more than one general-purpose processor, the method comprising:
- receiving frame information transmitted over the network at the port switch;
- determining, at the port switch, at least one port for the received frame information;
- and
- directing the frame information to at least one or more general-purpose processors based on the determined port(s).
