摘要： A method for operating plurality of DSL modem transmitters integrated within a circuit card. The method includes each DSL modem transmitter: generating a full power physical frame when the DSL modem transmitter is provided with data to transmit; generating a low power physical frame having a control channel signal component and no data; and selecting between the full power physical frame and the low power physical frame for transmission from the DSL modem transmitter, wherein selection of the low power physical frame for transmission from the DSL modem transmitter is based only on the DSL modem transmitter having no data to transmit. The method further includes limiting aggregate flow of data to the plurality of DSL modem transmitters such that a total power required by the plurality of DSL modem transmitters is held below a predefined target power level.

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 apparatus useful in network management which makes intelligent, high speed, connection allocation decisions, overcoming difficulties encountered heretofore and providing enhanced network services. During episodes of network congestion, some connection requests for a class of service of low value and with currently a high number of existing connections may be purposefully ignored (not acknowledged with an Acknowledge (ACK) packet) so that the processing capability of a device will not become overwhelmed, causing the dropping of new connection is to note the numbers of connections of different classes relative to their service-level contracts, to ignore abundant, low-value connection requests in accordance with value policies when and only when necessary, and to insure that valuable new connection requests that conform to their contract connection rates can be intelligently accommodated.

摘要： A method, system and computer program product for eliminating memory corruption when performing multi-threaded tree operations. A network processor may receive a command to perform a tree operation on a tree on one or more of multiple threads. Upon performing the requested tree operation, the network processor may lock one or more resources during a portion of the execution of the requested tree operation using one or more semaphores. A semaphore may refer to a flag used to indicate whether to “lock” or make available the resource associated with the semaphore. Locking may refer to preventing the resource from being available to other threads. Hence, by locking one or more resources during a portion of the tree operation, memory corruption may be eliminated in a multiple thread system while preventing these resources from being used by other threads for a minimal amount of time.

摘要： A method and system for improving the performance of a cache. The cache may include a tag entry that identifies the previously requested address by the processor whose data was not located in the cache. If the processor requests that address a second time, then there is a significant probability that the address will be accessed again. When the processor requests the address identified by the tag entry a second time, the cache is updated by inserting the data located at that address and evicting the data located in the least recently used entry. In this manner, data will not be evicted from the cache unless there is a significant probability that the data placed in the cache will likely be accessed again. Hence, data may not be evicted in the cache by the processor and replaced with data that will not be reused, such as in an interrupt routine.
摘要翻译：一种用于提高缓存性能的方法和系统。缓存可以包括标识条目，其标识由数据未位于高速缓存中的处理器先前请求的地址。如果处理器第二次请求该地址，则重新有可能再次访问该地址。当处理器第二次请求由标签条目标识的地址时，通过插入位于该地址的数据并驱逐位于最近最少使用的条目中的数据来更新高速缓存。以这种方式，除非存在可能再次访问高速缓存中的数据的重大概率，否则数据将不会从高速缓存中逐出。因此，数据可能不会被处理器在高速缓存中驱逐，并且被替换为不被重用的数据，例如在中断程序中。

摘要： A low power DSL modem transmitter, suitable for incorporation in integrated DSLAM server line cards, transmits full power physical frames which include a control channel and a data field when data is available for transmission and physical frames having only a control channel or a control channel and a low power synchronization field when data is not available for transmission. And a method for controlling the total power dissipated in the integrated DSLAM by selectively restricting the flow of data packets to the DSLs.

摘要： A shared digital subscriber line modem achieves reduced total power consumption and data security by generating and transmitting a physical data frame which includes a control channel and a data field to only the connected client modem associated with the intended recipient. A second physical frame which does not include the data field is generated and transmitted to all of the other connected client modems. This method results in a reduction in the power required and provides improved data security by preventing data access to non-addressed client modems.

摘要： A method and system for storing and searching for prefixes for rules, such as filter rules, in a computer system is disclosed. The method and system include providing a ternary content addressable memory (TCAM). The filter rules use range(s) of values in at least one dimension and correspond to prefix(es). The range(s) are described by prefix(es). Some filter rules may intersect. The method and system include providing priorities for the filter rules. The priorities include at least one different priority for the filter rules that intersect. The method and system also include storing the prefixes in the TCAM in block(s) in an order based upon the priorities of the filter rules. In another aspect, the method and system include searching the TCAM for a longest prefix match for a key and searching an additional storage for an almost exact match for the key in parallel with the TCAM. In this aspect, the method and system include returning the longest prefix match having a lowest or a highest location if the longest prefix match is found in the TCAM and the almost exact match is not found in the additional storage.

摘要： The decision to discard or forward a packet is made by a flow control mechanism, upstream from the forwarding engine in the node of a communication network. The forwarding engine includes a switch with mechanism to detect congestion in the switch and return a binary signal B indicating congestion or no congestion. The flow control mechanism uses B and other network related information to generate a probability transmission table against which received packets are tested to determine proactively whether a packet is to be discarded or forwarded.
