摘要： Systems and methods for user device registration are disclosed. In certain embodiments, at least a first edge device in a group of edge devices enters a mass-restart mode. The first edge device receives a request for registration from a user device and determines whether the user device is currently registered through the first edge device. The first edge device generates a notification associated with the user device if the user device is not currently registered through the first edge device. A second edge device in the group of edge devices receives the notification and determines whether the user device is currently registered through the second edge device based on the notification. Registration information about the user device is deleted from the second edge device if the user device is currently registered through the second edge device.

摘要： Methods and apparatuses, including computer program products, are described for priority policing of requests with deferred determination of priority level. The method includes directing each packet in a data stream to a policer. The method also includes determining whether to allow, reject, or conditionally pass each packet through the policer based on parameters associated with the policer. The method also includes directing each packet conditionally passed by the policer to a classifier associated with the policer. The method also includes determining, by the classifier, a priority value of each packet received from the policer. The method also includes directing, by the classifier, each prioritized packet to the policer. The method also includes determining whether to allow or reject each prioritized packet through the policer based on the priority value.

摘要： The invention includes two hosts having synchronized information to provide graceful failover for an SSCOP Service Access Point. Each host connected to the same SSCOP SS7 link, and has a Link Manager, SSCF-NNI layer, and SSCOP layer. For each link, there is an instance of SSCF-NNI state machine running in stack and similarly for each link there is an instance of SSCOP state machine running in the stack. Once the Link Manager detects that the active host on the redundancy group for SS7 links has failed, it checks its list of links, whether the failed host was the active host for those links and whether the links were active. If the Link Manager determines that the active host has failed and the links were active, it informs the SSCF-NNI and the SSCOP, which then switch the corresponding state machine from a default “Idle” state to an “In Service” and “Outgoing Recovery Pending” state respectively. By following the procedures defined for SSCOP in Q.2110 after this point on, SSCOP state machine eventually switches to “Data Transfer Ready” state and the standby host thereby becomes the active host in a transparent manner to the SSCOP user.

摘要： A method for control of real-time traffic entry of a managed packet network includes the step of receiving, from a border element processor, a first message indicative of a new active registration request associated with a client. The border element processor is one of a plurality of border element processors at an edge of a managed packet network controlling packets (e.g., relating to real-time multimedia traffic) entering the managed packet network. The method also includes the step of load balancing, by a load balancing engine, the new active registration request across the plurality of border element processors and assigning the client to a designated border element processor. A second message is generated in response to the new activation registration request. The second message includes a parameter identifying the designated border element processor assigned to the client.

摘要： Methods and apparatuses, including computer program products, are described for determining expiration time of bindings for NAT devices. A first device receives a first request including a first source IP address/port pair of a first NAT binding, and transmits a response. The first device receives a second request including a second source IP address/port pair of a second NAT binding, and transmits a response. The first device sets a refresh time T1 of the first NAT binding to be shorter than an expected minimum expiration time of the first NAT binding, transmits one or more messages via the second NAT binding where a sending interval time T2 of the second NAT binding is longer than T1, increments T2 when a response is received, and if a response to any of the messages is not received, sets T1 equal to the last T2 value for which a response was received.

摘要： A computer-implemented method for inserting an out-of-band signaling packet into a real-time protocol (RTP) stream is provided. The method includes receiving the out-of-band signaling packet intended for transmission to a user device and forming a synthesized packet based on payload information from the out-of-band signaling packet and header information stored in a data structure describing the RTP stream. The method also includes inserting the synthesized packet into the RTP stream. The method further includes receiving an RTP packet intended for transmission to the user device via the RTP stream, analyzing an insertion sequence number and an insertion flag maintained in the data structure, and discarding or forwarding the RTP packet via the RTP stream based on the analyzing.

摘要： Described are computer-based methods and apparatuses, including computer program products, for load balancing among VOIP servers. An identity table includes an identity entry for a plurality of servers, each identity entry comprising a FQDN and load balancing information. A persistence table stores persistence entries indicative of a persistent connection between a client and a server. Updated load balancing information determined by the first server is received. The identity table is updated based on the updated load balancing information. A service request is received from a client. If the client is not associated with a persistence entry, a second server is selected from the plurality of servers based on load balancing information for each identity entry in the identity table. A persistence entry is stored indicative of a persistent connection between the client and the selected second server, the persistence entry comprising a FQDN and an identifier for the client.
