摘要： According to the present invention there is provided to a method and system for efficiently routing IP fragments (i.e., datagrams) at layer 3 through layer 7 of the OSI model without reassembling the fragments. Time-consuming reassembly of fragments of a datagram at higher layers that would be required via conventional methods is avoided, thereby improving processing speed of fragments and utilizing fewer resources for processing fragments of a datagram than would be required during reassembly of the fragments via conventional methods. The method and system route a datagram that has been fragmented into a plurality of fragments utilizing content-based routing information included in one or more fragments of the plurality of fragments, comprising: generating a context for the datagram associated with routing the plurality of fragments of the datagram and setting the context for the datagram to passive until content-based routing information included in the one or more fragments is received; caching received fragments while the context is set to passive; determining a destination for routing the plurality of fragments when content-based routing information included in the one or more fragments is received and setting the context for the datagram to active; and routing any cached fragments and subsequently received fragments of the datagram to the determined destination while the context is active without reassembling the plurality of fragments into the datagram. Additionally, a router and server load balancer incorporating the present invention are provided.

摘要： A method and system for performing network address translations for a session in a network is disclosed. The network includes at least one local network domain, and the at least one local network domain includes at least one computer system. Each computer system has a local address and is associated with a global address. The session exchanges packets that travel between the computer system within the local network domain and another computer system which may be outside of the local network domain. Each packet includes source and destination information. The method and system include determining a direction of travel for each packet, inbound or outbound, by searching a global address table for a match of a key for each packet. The key is provided using a portion of the destination information. The global address table includes at least one entry. Each entry corresponds to the global address for a first corresponding computer system. The method and system also include asymmetrically translating the source and destination information for each packet using an address translation table or session table based on whether or not the full match is found. The destination information is translated using information in the session table if the packet is inbound. The source information is translated based on the address translation table if the packet is outbound. The address translation table includes at least one entry. Each entry corresponds to the local address for a first corresponding computer system or a global host name for a shared host.

摘要： A method and system for performing a pattern match search for a data string having a plurality of characters separated by delimiters. In accordance with the method of the present invention a search key is constructed by generating a full match search increment comprising the binary representation of a data string element, wherein the data string element comprises all characters between a pair of delimiters. The search key is completed by concatenating a pattern search prefix to the full match search increment, wherein the pattern search prefix is a cumulative pattern search result of each previous full match search increment. A full match search is then performed within a lookup table utilizing the search key. In response to finding a matching pattern within the lookup table, the process returns to constructing a next search key. In response to not finding a matching pattern, the previous full match search result is utilized to process the data string.

摘要： A processing system includes a memory and a first core configured to process applications. The first core includes a first cache. The processing system includes a mechanism configured to capture a sequence of addresses of the application that miss the first cache in the first core and to place the sequence of addresses in a storage array; and a second core configured to process at least one software algorithm. The at least one software algorithm utilizes the sequence of addresses from the storage array to generate a sequence of prefetch addresses. The second core issues prefetch requests for the sequence of the prefetch addresses to the memory to obtain prefetched data and the prefetched data is provided to the first core if requested.

摘要： A method and system for identifying a data structure associated with a packet of data. A processor internal to a packet processor may extract one or more fields in a packet header field of a received packet of data to generate a search key. The internal processor may then be configured to select which table, e.g., routing table, quality of service table, filter table, needs to be accessed using the search key in order to process the received packet of data. A determination may then be made by the internal processor as to whether a CAM or a hash table and a Patricia Tree are used to identify the data structure associated with the received packet of data. Based on table definitions in a register, the internal processor may make such a determination.

摘要： A method, computer program product and system for facilitating inter-digital signal processing (DSP) data communications. A direct memory access (DMA) controller may be configured to facilitate transfers of data between a first and a second DSP processor core coupled to the DMA controller. The DMA controller may read a data structure, referred to as a “buffer descriptor block,” to perform the data transfer. The buffer descriptor block may store both a source address and a destination address indicating where the data is to be retrieved and stored. The buffer descriptor block may further store a value, e.g., number of bytes, indicating a size of the data to be transferred. The DMA controller may then transfer the data located at the source address in the first DSP processor core, with a size, e.g., number of bytes, indicated from the buffer descriptor block, to the destination address in the second DSP processor core.
