| 20120096170 | REPLENISHING A USER ACCOUNT WITH MORE ACCESS RESOURCES NEEDED FOR ACCESSING NETWORK SERVICES - A network access server (NAS) determines the status of availability (e.g., how much more quota is unused) of an access resource, and sends a notification embedded in a point-to-point protocol (PPP) packet. The format of the packet is chosen such that definition/use of higher layers (e.g., HTTP) is not required to communicate the status to a client system. As a result, the user may be notified even if software such as web browser is not being executed on the client system. | 04-19-2012 |

| 20110222560 | PHYSICAL LAYER TRANSCEIVER WITH INTEGRATED TIME SYNCHRONIZATION - Disclosed, inter alia, is a Physical Layer Transceiver (PHY) with integrated time synchronization, such as, but not limited to, IEEE 1588 Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems. The PHY includes circuitry to maintain a current time, and to trigger the storage of timestamps corresponding to received frames. Typically, in response to a request from an external device, the timestamps are retrieved from storage and are communicated to the external device. By moving the triggering of the storage of the timestamps by the PHY itself, rather than by a monitoring of the traffic between the PHY and the Media Access Controller (MAC), higher accuracy can typically be achieved | 09-15-2011 |
| 20100228860 | Supporting a Community of Subscribers in an Environment Using a Service Selection Gateway (SSG) - A service policy manager may be used to enable a first subscriber in a community to administer rules on another subscriber in the same community. A service selection gateway (SSG) may then be configured according to the rules to provides services according to the rules. As a result, the services provided to a subscriber depend not just on the individual profile of the subscriber, but also potentially on the rules administered by other members of the communities the subscriber is a part of. | 09-09-2010 |
| 20090290590 | FORWARDING PACKETS IN A GATEWAY PERFORMING NETWORK ADDRESS TRANSLATION (NAT) - A gateway device providing a search utility to determine both NAT information and forwarding information (“both pieces of information”) in a single search operation. The single search operation may be implemented using a single table storing both pieces of information necessary for processing a packet. As a result, both pieces of information can be potentially retrieved in a single memory access. Due to the single (or few) memory access, the throughput performance of a gateway may be enhanced. In an embodiment, the gateway is implemented as a service selection gateway which provides connectivity between multiple remote systems and service domains. The NAT/forwarding information is partitioned according to service domains such that the information needed to process packets from/to the same service domain is contained in the same table. | 11-26-2009 |
| 20090154483 | A 3-LEVEL QUEUING SCHEDULER SUPPORTING FLEXIBLE CONFIGURATION AND ETHERCHANNEL - In one embodiment, a scheduler for a queue hierarchy only accesses sub-groups of bucket nodes in order to determine the best eligible queue bucket to transmit next. Etherchannel address hashing is performed after scheduling so that an Etherchannel queue including a single queue in the hierarchy is implemented to guarantee quality of service. | 06-18-2009 |
| 20090030693 | AUTOMATED NEAR-END DISTORTION DETECTION FOR VOICE COMMUNICATION SYSTEMS - In one embodiment, a method for providing voice quality assurance is provided. The method determines voice information for an end point in a voice communication system. The voice information may be from an ingress microphone. The method determines if the voice quality is considered degraded based on an analysis of the voice information. For example, the voice information may indicate that it is distorted, too loud, too soft, is subject to an external noise, etc. Feedback information is determined if the voice quality is considered degraded where the feedback information designed to improve voice quality at an ingress point for a user speaking. The feedback information is then outputted at the end point to the user using the end point. | 01-29-2009 |
| 20080307234 | USE OF MOBILE COMMUNICATION NETWORK CREDENTIALS TO PROTECT THE TRANSFER OF POSTURE DATA - In one embodiment, a method for using credentials for a mobile node to protect the transfer of posture data is provided. A network access device receives a message from a mobile node for access to a network. The message includes posture data encrypted using credentials for the mobile node. The credentials may be found in a storage card that is used to identify the mobile node. The network access device determines decryption information for the mobile node. For example, the credentials for the mobile node may be stored in a home location register (HLR) and are retrieved. The posture data is then decrypted using the credentials. The posture data is processed in a network admission control procedure for allowing access to the network. For example, a policy for access to the network may be installed based on the posture data. | 12-11-2008 |
| 20080235508 | Reducing processing load in proxies for secure communications - In one embodiment, a method for providing secure communications using a proxy is provided. The proxy negotiates with a client and a server to determine a session key to use with communications between the client and the proxy and between the proxy and the server. Encrypted data may then be received from the client at the proxy. The proxy can decrypt the encrypted data for processing using the session key. In one embodiment, the decrypted data is not altered. The proxy then sends the encrypted data that was received from the client to the server without re-encrypting the data that was decrypted. Because the proxy did not alter the data in its processing of the decrypted data and the same session key is used between communications for the proxy and the server, the encrypted data stream that was received from the client can be forwarded to the server. | 09-25-2008 |
| 20080205396 | Time-based authorization of Internet Protocol (IP) multicast subscription services - A switching device (e.g., router, bridge) provides time-based authorization of multicast services. When a message is received to request the delivery of a multicast service or a first message is sent to a multicast group, a subscription policy for the IP multicast subscription service is retrieved. This subscription policy includes one or more limitations which allow the IP multicast subscription service during some predefined time of day/week or duration but prevent the IP multicast subscription service during some predefined time of day/week or duration. The switching device is configured to enforce these time-based authorization of multicast services policies. | 08-28-2008 |
