摘要： Aspects of a method and system for compensating for estimated distortion in a transmitter by utilizing a digital predistortion scheme with a quadrature feedback mixer configuration are presented. Aspects of the system may include an RF transmitter that enables generation of an RF output signal in response to one or more generated input signals. One or more feedback signals may be generated by performing frequency downconversion on the RF output signal within a corresponding one or more feedback mixer circuits. The generated one or more feedback signals may be inserted at a corresponding one or more insertion points in an RF receiver. Each insertion point may be between a receiver mixer circuit and corresponding circuits that generate a baseband signal based on the corresponding one of the feedback signals.

摘要： A method and apparatus is described to process packets in a network. The method may comprise receiving the packet and determining a length K of the packet. If the length of the packet is less than a reference length M then no analysis may be performed on the packet. However, if the packet length K is not less than M, the method may determine if the packet length K is at least greater than a reference window size WRef. When the packet length is greater than WRef then a window size W for the processing of the packets is set equal to WRef; and the packet length is less than WRef then a window size W for the processing of the packets is set equal to the packet size K. Thereafter, the packet is processed using the window size W.

摘要： A method and apparatus for detecting malicious attacks is described. The method may comprise obtaining routing information from a packet communicated via a network and maintaining a count of packets associated with a device associated with the routing information. For example, the routing information may a source or destination IP address, a port number, or any other routing information. The device may be classified as a potentially malicious device when the count exceeds a threshold. The count may be incremented when the TCP SYN flag is set and the TCP ACK flag is not set. An embodiment comprises obtaining a source hash of the source IP address and a destination hash of the destination IP address. Thereafter, the source hash and the destination hash may be mapped to multi stage filters. The device associated with the packet may then be selectively categorizing as a suspicious device.

摘要： A combined hash table/bucket trie technique facilitates fast, deterministic, memory-efficient exact match look-ups on extremely large tables. A limited number of hash keys which collide on the same location can be stored in the hash table. If further keys collide on the same location, a bucket trie is formed, the colliding keys are stored in the trie, and trie traversal information is stored in the hash table. Regardless of the number of buckets in the trie, an input key need only be compared with the keys in one bucket to detect a stored key identical to the input key or conclude that no stored key is identical to the input key.

摘要： A mechanism for operating a configurable switch to dynamically (i) route each of the data packets in an ordered string from a particular switch input port through a selected member output port of a hunt group; and (ii) route data packets which need not be transmitted in order from the input ports to available member output ports of the hunt group, as the members become available. A controller assigns each input port a service number, and directs member output ports to handle requests for ordered data packet transmissions from input ports with particular service numbers, such that the ordered transfers from an input port are handled by a single member of each group. The input port broadcasts, through the switch, a request to send ordered data packets through a particular hunt group and includes its service number in the request. The group member assigned to handle ordered transfers from the input port responds by identifying itself. Thereafter, the input port sends its ordered data packets to the identified member. Unordered data packets are queued and routed dynamically through the members of the group, as the members become available. In a local area network, data is sent from a source station to file servers using server group identifiers for multiple-route transfers or individual server identifiers for single-route transfers.

摘要： A flow control system is disclosed, for a transmitting node and a receiving node. The transmitting node and the receiving node are linked together through multiple connections or virtual circuits over a communications link. A flow control circuit in the transmitting node limits the amount of bandwidth used over each individual connection, and over all of the connections combined. In an example embodiment, a global counter is used to maintain the total amount of bandwidth consumed overall during a predetermined time period, and a global limit register limits the maximum amount of bandwidth allowed consumed by any single connection during the time period. When the global counter exceeds an upper threshold value, the global limit register is set to a minimum value representing the minimum amount of bandwidth guaranteed to each connection during the time period. If a connection transmits an amount of bandwidth greater than or equal to the value in the global limit register, further transmissions on that connection are disabled for the remainder of the current time period.

摘要： A method of providing loop free and shortest path routing of data packets in a network having a plurality of switches, routing messages for communicating network topology information between the switches, a plurality of links connecting the switches and a plurality of channels connecting the switches to the links. The loop free routing of data packets is achieved through modifications to known link state packet (LSP) routing protocols and permits each switch to inform adjacent switches in the network of the information in the switch's database used to compute forwarding tables. A switch uses a received LSP to compute a forwarding table and informs neighboring switches on attached links of the routing change. The switch discards any subsequent data packets whose path would be affected by the changed routing information. The discarding of data packets continues until the switch receives notification from each adjacent switch affected by the changed routing information that all affected routing paths have been recalculated and the forwarding table of each affected switch has been updated. Thus, while adjacent switches temporarily contain inconsistent LSP databases and possibly inconsistent forwarding tables, the looping of data packets is prevented. Shortest path routing for data packets from a source endnode to a destination endnode is achieved by assuring that the first switch to forward the packet is on the shortest path to the packet's destination endnode. A source endnode transmits a data packet with an appropriate destination header and the determination of the actual routing path is performed transparently to endnodes. A data packet reaches its destination endnode by following the shortest path possible based on the network topology as represented in the database of the first switch that forwards it.
摘要翻译：一种在具有多个交换机的网络中提供数据分组的无循环和最短路径路由的方法，用于在交换机之间传送网络拓扑信息的路由消息，连接交换机的多个链路和将交换机连接到链接。通过修改已知的链路状态分组（LSP）路由协议来实现数据分组的无循环路由，并允许每个交换机通知交换机用于计算转发表的数据库中的信息的网络中的相邻交换机。交换机使用接收到的LSP来计算转发表，并通知相邻交换机对路由更改的附加链路。交换机将丢弃其路由将被更改的路由信息影响的任何后续数据包。丢弃数据包继续进行，直到交换机接收到受改变的路由信息影响的每个相邻交换机的通知，所有受影响的路由路径已被重新计算，并且每个受影响的交换机的转发表已被更新。因此，相邻交换机临时包含不一致的LSP数据库和可能不一致的转发表，防止了数据包的循环。通过确保转发数据包的第一个交换机位于分组目的地节点的最短路径上，实现从源节点到目标节点的数据包的最短路径路由。源端节点发送具有适当目的地头部的数据分组，并且实际路由路径的确定对端点进行透明化。数据包通过遵循可转发的第一个交换机的数据库中基于网络拓扑的最短路径到达目的地节点。
