Abstract

A multiple network protocol encoder/decoder comprising a network protocol layer, data handler, O. S. state machine, and memory manager state machines implemented at a hardware gate level. Network packets are received from a physical transport level mechanism by the network protocol layer state machine which decodes network protocols such as TCP, IP, user datagram protocol (UDP), PPP, and raw socket concurrently as each byte is received. Each protocol handler parses and strips header information immediately from the packet, requiring no intermediate memory. The resulting data are passed to the data handler which consists of data state machines that decode data formats such as email, graphics, hypertext transfer protocol (HTTP), Java, and hypertext markup language (HTML). Each data state machine reacts accordingly to the pertinent data, and any data that are required by more than one data state machine is provided to each state machine concurrently, and any data required more than once by a specific data state machine, are placed in a specific memory location with a pointer designating such data (thereby ensuring minimal memory usage). Resulting display data are immediately passed to a display controller. Any outgoing network packets are created by the data state machines and passed through the network protocol state machine which adds header information and forwards the resulting network packet via a transport level mechanism.

Description of the invention (2) System memory, the software program that processes data implements a connection layer agreement. Once data is transferred to system memory through network device hardware, software programs that process the data implement higher-level protocols, such as networking, transmission, and communication protocols, and data processors. The benefit of this implementation is that it allows the use of a general-purpose device such as a computer in many different network settings and supports any random network application that may be required. However, the result of this implementation is that the system requires a high processor cost A large amount of system memory requires complex settings on the computer user side to coordinate different software protocols and the computer's operating system and the data processor of the computer and network hardware. In 1996] U.S. Patent No. 5 4 8 5 4 6 0 issued to Schrier et al. On 16th, teaches a method of operating multiple software protocols stacked on a device to achieve the same protocol, and illustrates the processing in This high expense is required in time. This implementation is used in a disk operating system (DOS) machine running Microsoft Windows software. In normal operation, once the hardware verifies the transmission or connection layer agreement, the resulting data packet is sent to a software layer that determines the packet format and strips off any specific packet headers. The packets are then sent to different protocol stacks that are evaluated by a particular protocol. However, packets may be sent to several protocol stacks before they are received or rejected. The time delay created by the software protocol stack prevents real-time processing of sound and image transmission: data must be cached before recovery. Obviously, the processing cost required to process an agreement is very high and cumbersome, and it is only suitable for applications with a powerful central processing unit (CPU) and large memory. Consumer products that are inappropriate for the traditional model of network equipment are entering the market. A few examples of these products are pagers, mobile phones, game consoles,

Description of the invention ¢ 8) and passed to the operating system state machine 3 1 5. The operating system state machine 3 1 5 processes the input and passes it as a command to the TTP client 31 1. The HTTP client creates a request packet and passes it to the Transmission Control Protocol (TCP) layer 308 via the port decoder 309. The TCP layer processes the appropriate TCP header and passes it to the IP layer 307. The IP layer then processes the appropriate IP header and passes the packet to the PPP layer 306. The PPP layer processes the appropriate headers, adds an FCS, and passes the data to the physical transmission interface 305. The physical transmission interface serializes the data into a bit stream and passes the packet to the modem unit 304. When the host server receives the request, it sends the requested contract graphics expert organization (JPEG) image to the client system. MODEM3 0 4 which indicates that the data arrives to the physical transmission interface 3 0 5 receives the data first. Then the physical transmission interface reads the bit string data from the MODEM, converts it into a parallel byte data, and indicates to the PPP layer 3 0 6 that the data has arrived. The PPP layer reads the received data. When it detects a valid start byte, it starts analyzing the input bytes. When the byte stream reaches the P p p region, it is decoded by the p p p layer, and in this example the embedded packet is decoded as the I p type. In response to this protocol byte, the PPP layer allows the IP layer 307 and indicates to it that IP data is being received. All subsequent data received are passed directly to the I p layer. Then the IP layer starts to analyze the input data bytes. When it reaches the IP header agreement area, it determines which higher-level agreement is allowed. In this example, the p layer decodes the protocol area as a TCP type. At this point, the ip layer allows the TCP layer 308 and indicates to it when it receives Tcp data. When this indicator is activated, 'all the data bytes in the next received packets are passed to the IP and TCp layers (the P layer needs data bytes to complete the checksum calculation). Then the TCP layer starts to analyze the input data.

Figure 12 depicts a received network packet. The packet contains the following items shown from left to right: PPP header IP header TCP header JPEG data PPP field checksum (FCS) When detected and shown in the figure When a valid start byte is generated in the ppp block in 1 3, the line indicating the point to the protocol layer enable (PPP LAYER ENABLE) is activated. Once this line rises, the remaining PPP blocks are activated. In the PPP header is a field indicating the type of the protocol that encapsulates the PPP packet. In an uncompressed PPP header 'these bytes are 4 and 5 (calculation start byte 0 X 7e) ° In Figure 12' these bytes indicate that the encapsulated data is 0 of the p packet X 0 0 and 〇 2 1. After decoding this area, the PPP block activates the p-layer enable and PPP data area signals, which together allow the IP block in Figure 13. The PPP protocol area allows line decoding to the IP layer. The ppp data area line indicates that the input data bit stream is in the data area portion of the network packet. In order to allow the p-block above, these two must always be activated. Once the 1 p-block is allowed, it starts to analyze the input f-level groups.

The IP data area signal indicates that the input data bytes are in the data area of the IP. In order to allow the TCP block in Figure 13 the TCP layer enable and IP data area lines must be activated. Once the τ c p block is allowed, it starts analyzing the regions of the input data bytes. This field indicates which application or data processor the packaged data refers to. In FIG. 12, 'this area decodes port 0x0003. In FIG. 13, 'Port 3 is assigned an HTTP port. After decoding the destination area in the TCP header, the HTTP Allow line is activated, and the HTTP data area line is activated after several bytes, because there are two lines in the destination port area and the TCP data area. Once the HTTP block is allowed, it begins to analyze the input data bytes. When it decodes the header, it allows the JPEG decoder block in Fig. 13. Once the JPEG decoder is enabled, it starts processing the input bytes. The allow line is the only factory root line required to allow JPEG blocks.
