摘要： The present invention provides a method, computer-readable medium and device for dynamically managing allocation of bandwidth in a packet network using a Dynamic Setting Scheme (DSS) for Class Based Queuing (CBQ). The method includes the steps of maintaining a minimized reserved portion of bandwidth to minimize delay jitter and maximizing a shared portion of bandwidth to maximize overall bandwidth utilization. Allocation of bandwidth may be based on a sharing tree hierarchical scheme that provides for temporary borrowing of bandwidth by real-time applications from bandwidth of non-real-time applications and blocks borrowing of bandwidth by non-real-time applications from bandwidth of real-time applications. DSS typically provides for using measurable parameters, such as queue length and number of borrowing attempts per a predetermined length of time/observation window, as control triggers for implementing adjustment of bandwidth allocation. In one embodiment, the steps include measuring a predetermined parameter at predetermined observation window times and dynamically adjusting allocated bandwidth for parent classes of real-time traffic by adjusting an average of the predetermined parameter to have a value within a predetermined stable region.

摘要： A method reduces the number of queries generated to a number portability database. The number portable communication system includes a local cache associated with the switching office or facility responsible for identifying and controlling the routing of calls to portable numbers. By including the cache and only generating a request to the number portability database when the cache either does not contain LRN response information or if a call attempted based on LRN response information in the cache fails, the total number of queries to the number portability database are reduced. This reduces query traffic as well as speeds up the processing of calls able to use cached information.

摘要： A method of routing an interim NP call in which it is determined to give a called number interim NP redirection rather than conventional RCF redirection when the called number is to be ported. When a ported call is to receive interim NP redirection and SS7 networking is used, an Initial Address Message for the call is created with the Called Party Number parameter of the Initial Address Message populated with the Location Routing Number for the switch to which the called number has been ported. The Generic Address Parameter of the Initial Address Message is populated with the called number and the M bit of the Forward Call Indicator parameter of the Initial Address Message is set. The call is then redirected to the switch to which the called number has been ported based on the Location Routing Number in the Called Party Number parameter of an Initial Address Message. This method avoids the use of RCF "shadow numbers" and the need to query an external long-term NP database.

摘要： A server on a packet network is protected from attack by flooding SYN messages that request a connection by comparing the number of SYN messages received within a preselected time interval N, where N is a number SYN messages within said preselected time that, with a predetermined probability, can be considered to be bona fide. When the number of received SYN messages within the preselected time interval is greater than N, corrective action is taken, such as discarding all SYN messages above the received N messages.

摘要： A method and apparatus for use in a network utilizing Internet Protocol (IP), Resource Reservation Protocol (RSVP), and Asynchronous Transfer Mode (ATM) protocol is provided. An intelligent policy mapping database (PMD) accessible at the network level by both the RSVP and ATM protocol stacks maps RSVP parameters to ATM parameters with input from factors outside of the RSVP or ATM protocol stacks, e.g., general customer data. With the basis of customer data or other information outside of the RSVP and ATM protocol stacks, a network reservation message to the PMD contains RSVP flow specifications which are mapped to correlated ATM Quality of Service (QoS) parameters.

摘要： A method is provided which reduces post-dial delay in a number portability environment. In particular, a switching office which controls call routing to portable numbers (NPA-NXXs) contains a cache for which location routing number response information may be stored. The processing office concurrently checks the cache for LRN response information corresponding to the dialed number and launches a query to a number portability database. Thus, if the LRN response information in the cache is valid then the call will be routed in the timeliest manner. However, if either the cache does not have any LRN response information or the LRN response information in the cache proves not to be valid then, the switching office will have received the LRN response information from the database more quickly based on the concurrent launching of a query. Therefore, a more timely attempt at establishing a proper connection to the dialed number will occur thereby reducing post-dial delay.

摘要： The system and method of the present invention completes at least two calls originating from terminal equipment located at a premises and connected by a point-of-attachment having a single phone number to a public switched telephone network where a dial tone is provided to the premises. Multiple calls are now allowed with an analog interface to the public switched telephone network. At least two calls and control channel are combined into a modulated analog signal having a separate channel for each call and transmitted through a modulation/demodulation device as a modulated analog signal to the public switched telephone network. The modulated analog signal is split into respective calls and control channel. Each call is forwarded to a respective remote device based on the identity information and auxiliary information received through the control channel.
