摘要： A system, method and program product for blocking unwanted e-mails. An e-mail is identified as unwanted. A source IP address of the unwanted e-mail is determined. Other source IP addresses owned or registered by an owner or registrant of the source IP address of the unwanted e-mail are determined. Subsequent e-mails from the source IP address and the other IP addresses are blocked. This will thwart a spammer who shifts to a new source IP address when its spam is blocked from one source IP address.

摘要： A data flow control method and system within a data switch. The data switch includes a plurality of input sections each having an associated input buffer and each transmitting data to an output section. In response to a detection of congestion within the output section, data transmissions from the plurality of input sections to the output section are paused. Input buffer occupancies of each of the input sections are then determined. Thereafter, and in response to a backpressure relief signal, the restart of said data transmission from each of the input sections to the output section is delayed in inverse proportion to each of the determined input buffer occupancies.

摘要： System, method and computer program for authenticating a user of a client computer to a remote server computer. A client computer initially sends a userID but not a password of the user to the remote server computer. In response to the userID, the server computer determines a subsequent time window during which the server computer will consider for authentication submission of a combination of the userID and a password. The server computer notifies the client computer of the time window. After receipt of the notification from the server computer, during the time window, the client computer sends the userID and a corresponding password to the server computer. In response to receipt of the userID and the corresponding password from the client computer, the server computer determines if the combination of the userID and the corresponding password is valid. If the combination of the userID and the corresponding password is valid, the server computer notifies the client computer that the combination of the userID and the corresponding password is valid. In response, the client computer establishes a session with the server computer and accesses a resource requiring a valid combination of userID and password to access. The server computer ignores combinations of userIDs and passwords submitted before or after the time window.

摘要： A remote user, two-way authentication and password change protocol that also allows parties to optionally establish a session key which can be used to protect subsequent communication. In a preferred embodiment, a challenge token is generated and exchanged which is a one-time value that includes a random value that changes from session to session. The construction and use of the challenge token avoids transmission of the password or even the transmission of a digest of the password itself. Thus the challenge token does not reveal any information about a secret password or a digest of the password.

摘要： A method and system for controlling a plurality of pipes in a computer network, including at least one processor for a switch, the at least one processor having a queue, the plurality of pipes utilizing the queue for transmitting traffic through the switch, wherein each pipe is assigned a priority ranking class, each class has a unique priority rank with respect to each of the other classes, the ranks ranging from a highest priority rank to a lowest priority rank. A transmission probability is calculated for each pipe responsive to its priority rank. If excess bandwidth exists for the queue, the transmission probability of each pipe is linearly increased. Alternatively, if excess bandwidth does not exist, the transmission probability for each pipe is exponentially decreased. Packets are transferred from a pipe to the queue responsive to the pipe transmission probability and priority rank.

摘要： A method, system and computer program product for detecting the dissemination of malicious programs. The degree of randomness in the Internet Protocol (IP) destination addresses of received IP packets to be forwarded to an external network may be detected by performing a hash function on the IP destination addresses thereby generating one or more different hash values. If a high number of different hash values were generated for a small number of IP packets examined, then random IP destination addresses may be detected. By detecting random destination IP addresses, the dissemination of a malicious program, e.g., virus, worm program, may be detected.

摘要： A structure and technique for preventing collisions using a hash table in conjunction with a CAM to identify and prevent collisions of binary keys. A portion of the hash value of a binary key, which does not collide with a portion of the hash value of any other reference binary key, is used as an entry in the hash table. If two or more binary keys have identical values of the portions of the hash values, each of these binary keys are stored in their entirety, in the CAM. The key in the CAM provides a pointer to a data structure where the action associated with that binary key is stored. If the binary key is not found in the CAM, the binary key is hashed, and a specific entry in the hash table is selected using a portion of this hash value.

摘要： Novel data structures, methods and apparatus for a Software Managed Tree (SMT) which provides a mechanism to create tree structures that follow a search mechanism defined by a control point processor. The search mechanism does not require storage on the previous pointer and uses only a forward pointer along with a next bit or group of bits to test thereby reducing storage space for nodes. The search mechanism processes multiple filter rules for an application without requiring multiple searches and also allows various filter rules to be chained. Two patterns of the same length are stored in each leaf to define a range compare. A compare at the end operation is either a compare under range or a compare under mask. In a compare under range, the input key is checked to determine if it is in the range defined by the two patterns. In a compare under mask, the bits in the input key are compared with the bits in a first leaf pattern under a mask specified in a second leaf pattern.

摘要： A method and system for providing a path for a new flow between a source node and a destination node in a network is disclosed. The network has a plurality of nodes and a plurality of links between the nodes. The nodes include the source node and the destination node. Each of the links is capable of including a plurality of existing flows and has a capacity. Each of the existing flows has a minimum guaranteed bandwidth. The method and system include determining a benefit for each link of a portion of the plurality of links coupled with a node of the plurality of nodes. The benefit is determined based on the capacity of the link and the minimum guaranteed bandwidth for a portion of the plurality of existing flows that is through the link, the node being a part of the path. The method and system also include selecting a link of the portion of the plurality of links to be part of the path. The link has a maximum benefit for the first portion of the plurality of links and is coupled the node with a second node of the plurality of nodes.

摘要： A method and system for storing a plurality of filter rules in a computer system is disclosed. The plurality of filter rules uses at least one range of values in at least one dimension. The method and system include separating a portion of the plurality of filter rules into a plurality of pure subsets of filter rules. Each of the plurality of pure subsets of filter rules includes at least one of the plurality of filter rules. The method and system also include combining a portion of the plurality of pure subsets of filter rules to provide a combined subset and determining whether an efficiency of utilizing the plurality of filter rules is improved by combining the portion of the plurality of pure subsets of filter rules. The method and system further includes storing the plurality of filter rules including storing the portion of the plurality of subsets of filter rules as the combined subset if the efficiency of searching the plurality of filter rules is improved.
