摘要： A method and system for memory management in a network processing system provides for allocation of physical memory areas within network processors coupled to a control point processor by a bus. The allocation scheme provides a memory management layer without requiring a complete operating system interface and supports asynchronous completion of the allocation requests. Multicast allocation is supported allowing an allocation to be simultaneously requested on multiple network processors. The allocation mechanism returns a token, which may then be used to access the memory location via a protocol over the bus, and a single token may refer to an allocation made on several network processors where the actual physical addresses and memory configurations are different.

摘要： A system for controlling multicast traffic in a multiprocessing system is disclosed. The multiprocessing system includes a general-purpose processor, a plurality of network processors and a switch fabric. The system comprises a multicast identifier (MID) manager to manage a distributed database of MIDs. The distributed database includes at least one compound MID. The at least one compound MID structure further comprises a plurality of MIDs representing at least two multicast groups. The system also includes a MID processor which traverses the at least one compound MID and resolves it into its associated simple MIDs. Accordingly, the present invention provides for a system and method for efficiently controlling multicast transmissions when different types of multicast groups are to receive the multicast transmissions. In this system and method a new type of multicast identifier (MID) is provided, a compound MID. The compound MID is a single MID but references multiple MIDs. The system includes a MID manager which manages a distributed database of MIDS. Finally, the system and method includes at least one MID processor which accesses the appropriate compound MIDs and resolves them into the simple member MIDs to allow a router to provide the information to an appropriate bridge.

摘要： This process accepts rule domination declarations and subjects rules to a computer program which either finds a type of administrative error (cyclic domination) or assigns a priority number to each rule so that any two rules which intersect (some key fits both rules) have necessarily different priority numbers. In the case that priority numbers are assigned, the process goes on to check for a second type of administrative error, namely inclusion of a first rule in a second (every key which fits the first rule also fits the second), and with the second having higher priority (so that the first is never referenced). If neither error occurs, then the number of different priority numbers is minimized. Every key when tested by such a rule set with neither error must fit either no rules at all or must fit exactly one rule with highest priority. In the latter case, the action of the unambiguously determined rule can then be applied to the packet represented by the key.

摘要： A classification system includes a software managed tree testing bits from a key which labels an item. The bits are chosen by application of the Choice Bit Algorithm to the Rules in a Database of Rules. A controller including logic parses an unknown Key for bits to be tested in the decision nodes of a binary tree. Tests dictated by the tree are conducted in a predetermined way until all but one Rule from the database or all but a few Rules from the database are eliminated from consideration, whereupon the Key is fully tested by the one remaining Rule or in a lattice constructed of the remaining plurality of Rules, to determine an action to enforce on the item. Certain compare tests are used in the binary tree for the case that otherwise identical or similar rules are applied to integer ranges of key values which do not fall upon power of 2 boundaries. Furthermore, some very frequently occurring rules in such final tests might be designated as secondary rules, the remaining rules designated as primary rules, the entire decision tree recalculated using only primary rules, and the primary rules then connected to secondary rules only when logically necessary by means of a system of pointers making use of relative priorities of rules.

摘要： A method and system for reducing the lookup time in packet forwarding on computer networks. A first lookup is performed in a memory tree to find a first protocol forwarding entry in the memory tree. The forwarding entry includes first protocol (e.g., EGP) information and cached associated second protocol (e.g., IGP) information. Both EGP and IGP information are retrievable with the first lookup and used in the determination of an EGP route for the data packet. If the cached IGP information has been invalidated due to address updates, a second lookup can be performed to find an original IGP entry in the memory tree, the information from which can be cached in the EGP forwarding entry if a background maintenance task has finished designating all the EGP entries as having out-of-date caches.

摘要： A system and method in accordance with the present invention allows for an adapter to be utilized in a server environment that can accommodate both a 10 G and a 1 G source utilizing the same pins. This is accomplished through the use of a high speed serializer/deserializer (high speed serdes) which can accommodate both data sources. The high speed serdes allows for the use of a relatively low reference clock speed on the NIC to provide the proper clocking of the data sources and also allows for different modes to be set to accommodate the different data sources. Finally the system allows for the adapter to use the same pins for multiple data sources.
摘要翻译：根据本发明的系统和方法允许在可以使用相同引脚容纳10G和1G源的服务器环境中使用适配器。这是通过使用可以容纳两个数据源的高速串行器/解串器（高速serdes）来实现的。高速serdes允许在NIC上使用相对较低的参考时钟速度来提供数据源的适当时钟，并且还允许设置不同的模式以适应不同的数据源。最后，该系统允许适配器为多个数据源使用相同的引脚。

摘要： Apparatus for providing a checksum in a network transmission. In one aspect of the invention, a checksum for a packet to be transmitted on a network is determined by retrieving packet information from a storage device, the packet information to be included in the packet to be transmitted. A blind checksum value is determined based on the retrieved packet information, and the blind checksum value is adjusted to a protocol checksum based on descriptor information describing the structure of the packet. The protocol checksum is inserted in the packet before the packet is transmitted.

摘要： A system for reducing latency in a host Ethernet adapter (HEA) includes the following. First, the HEA receives a packet with an internet protocol (IP) header and data in the HEA. The HEA parses a connection identifier from the IP header and accesses a negative cache in the HEA to determine if the connection identifier is not in a memory external to the HEA. The HEA applies a default treatment to the packet if the connection identifier is not in the memory, thereby reducing latency by decreasing access to the memory.

摘要： In a network environment including one or more network processing (NP) devices implementing for communicating packets, each NP device supporting a forwarding table comprising entries to enable forwarding of received data packets from a source device to a destination device according to a routing protocol via a network connection, the network device routing receiving updated forwarding table entries from one or more network control devices executing routing protocol applications, a system and method for updating forwarding table entries comprises: generating for each forwarding table entry update, a data structure indicating identification of the routing protocol application and a version of a particular routing protocol application instance generating the entry update, the data structure received by the forwarding table and incorporated within a respective forwarding table entry; identifying for deletion forwarding table entries having data structures matching a designated selection criteria; and, deleting the designated forwarding table entries. By doing this old forwarding table entries in the forwarding table are updated efficiently without disrupting packet forwarding process.
