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in the EGP forwarding entry if a background maintenance task has finished designating all the EGP entries as having out-of-date caches.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： In a networking environment including one or more network processing (NP) devices and implementing a routing protocol for routing data packets from a source NP devices to destination NP devices via a switch fabric, with each network processing device supporting a number of interface ports, a system and method for enabling a routing system to recover more quickly that the routing protocol so as to significantly reduce the occurrence of lost data packets to a failed target interface/blade. The routing system is enabled to track the operational status of each network processor device and operational status of destination ports supported by each network processor device in the system, and maintains the operational status as a data structure at each network processing device. Prior to routing packets, an expedient logical determination is made as to the operational status of a target network processing device and target interface port of a current packet to be routed as represented in the data structure maintained at the source NP device. If the target blade/interface is not operations, an alternative route may be provided by ECMP. In this manner, correct routing of packets is ensured with reduced occurrence of lost data packets due to failed target NP devices/ports.

摘要： The CRC for the CPS Header of an ATM AAL2 cell is generated by a CRC generator which uses the 8 bits of the CID field to generate partial 5 bits CRCs which are loaded in a first table. The 6 bits LI field and 5 bits UUI field are added to the partial 5 bits CRC to form 16 bits. The CRC generator uses the 2.sup.16 bits to generate a second CRC table. The CRC for a particular CPS header is generated by correlating bits in the CID field, LI field and UUI field with the two tables.

摘要： The classification system of a network device includes a cache in which a mapping between predefined characteristics of TCP/IP packets and associated actions are stored in response to the first “Frequent Flyer” packet in of a session. Selected characteristics from subsequent received packets of that session are correlated with the predefined characteristics and the stored actions are applied to the received packets if the selected characteristics and the predefined characteristics match, thus reducing the processing required for subsequent packets. The packets selected for caching may be data packets. For mismatched characteristics, the full packet search of the classification system is used to determine the action to apply to the received packet.

摘要： A controllable mechanism for by-passing Layer 4 (L4) classification is based on the insertion into a set of Layer 3 (L3) rules in an L3 lookup tree set of Layer 4 (L4) Classification Required Flags. The state of the L4 classification flag is set by comparing the L4 classification rule to an IP (Internet Protocol) lookup rule. Routing is accomplished by selecting which rule to apply to the data packet and reading the state of the corresponding L4 Classification Required Flag. In response to a first state of the corresponding L4 Classification Required Flag, an L4 classification is performed followed by a routing of the data packet. In response to a second state of the corresponding L4 Classification Required Flag performing a routing of said data packet. In a second embodiment, the method inserts into a set of L3 rules in L3 lookup means a set L4 Classification Required Flags and Global Flags. A first state of the L4 Classification Required Flag is set when a new rule is added to L4 classification means, the new rule being correlatable to a single entry in L3 lookup means. Routing is accomplished by selecting which rule to apply to the data packet and reading the state of the corresponding L4 classification required flag. In response to a first state of the corresponding L4 classification flag, a L4 classification is performed followed by a routing of the data packet. In response to a second state of the corresponding L4 classification flag, the state of the Global Flag is read, and in response to a first state of the Global flag, a L4 classification is performed followed by a routing of the data packet. In response to a second state of the Global Flag, the data packet is routed.
摘要翻译：用于旁路第4层（L4）分类的可控机制是基于在第4层（L4）分类要求标志的L3查找树集中插入到一组第3层（L3）规则中。通过将L4分类规则与IP（因特网协议）查找规则进行比较来设定L4分类标志的状态。通过选择应用于数据包的规则并读取相应的L4分类要求标志的状态来完成路由。响应于对应的L4分类要求标志的第一状态，执行L4分类，然后进行数据分组的路由。响应于相应的L4分类要求标志的第二状态来执行所述数据分组的路由。在第二实施例中，该方法在L3查找中插入一组L3规则，即集合L4分类要求标志和全局标志。当将新规则添加到L4分类装置时，设置L4分类要求标志的第一状态，新规则可与L3查找装置中的单个条目相关。通过选择应用于数据包的规则并读取相应的L4分类所需标志的状态来完成路由。响应对应的L4分类标志的第一状态，执行L4分类，然后进行数据分组的路由。响应对应的L4分类标志的第二状态，读取全局标志的状态，并且响应于全局标志的第一状态，执行L4分类，然后进行数据分组的路由。响应全局标志的第二状态，数据包被路由。
