Abstract: A technique for adaptively load balancing connections in multi-link trunks is disclosed. The present invention provides an adaptive load balancing algorithm that utilizes relative link quality metrics to adjust traffic distribution between links. Link quality metrics may include short-term averages of an observed packet drop rate for each member link in a bundle. The present invention may dynamically adjust the number of flows on each link in proportion to available bandwidth. In addition, link quality metrics may be equalized, such that no link is more lossy than the others.

Abstract: Selectively replicating data from a network server to a mobile device during a synchronization is provided. The system and method of the invention associates mobile device users with roles that include rules. Each of the rules includes one or more conditions that can be either static or dynamic. When a rule is invoked, only those specific instances of data that satisfy the conditions of the rule are replicated to the mobile device. Whether a rule of a role is invoked can be made to depend on a device type of the mobile device. The method can also exclude data from replication where the user lacks an authorization to access a particular data type, even though a valid rule would otherwise permit the data to be synchronized.

Abstract: A VPN server on a radio access network may initiate a virtual private network (VPN) over a shared network, e.g., Internet, on behalf of a wireless terminal. The VPN may span the shared network, but not span the radio access network. As a result, the radio access network may be able to analyze and manipulate data sent by the wireless terminal. Additionally, the VPN may securely transport the data through the shared network.

A maximum value of the computed load balancing values is determined. A data path with the maximum value is selected for use in routing data. Also provided are techniques for dynamic load balancing in which, when a load balancing share of a data path is less than an actual load balancing share, the load balancing share of the data path is adjusted. Furthermore, provided are techniques for failover processing in which a command is routed through a second network adapter in response to determining that the command may not be routed through a first network adaptor.

A T-1 level can be divided into twenty four channels that are assigned to two or more mobile standards, and subscriber or network communications based on the two or more standards can be delivered to, for example, radio transmitters associated with the mobile standards. Channel allocation can be revised based upon requested capacity associated with the mobile standards.

The phone terminal sets up the IP address of main apparatus and the phone number as self-terminal information, thereby automating the phone terminal registration.

Abstract: A first communication device receives an ATM cell bound for a second ATM device from a first ATM device via an ATM interface, and then the first communication device sends a data frame including the ATM cell to the second ATM device via wide area Ethernet. In addition, the first communication device sends a synchronization frame to the second ATM device via the wide area Ethernet continuously at a predetermined time interval in accordance with a clock frequency of the first ATM device. A second communication device receives the synchronization frame and measures a clock frequency of the first ATM device in accordance with a time interval of receiving the synchronization frame so as to reproduce a clock having the same frequency as the measured clock frequency. After that, the second communication device sends the clock to the second ATM device via an ATM interface.

Abstract: The invented method and apparatus include a transport mechanism for transporting a non-V.42, e.g. a V.14 or synchronous modem, data stream in a modem relay connection utilizing the standard V.14 raw or character mode, the transport mechanism including a rate-control mechanism for substantially speed-matching the end-to-end flow of data. Preferably, speed-matching is based on a calculated effective data rate—which takes into account various character and link framing and compression overhead—rather than a physical layer rate. Rate-control methods include the use of receive not ready (RNR) to control data flow in a V.42 leg of a mixed non-V.42 and V.42 connection, a single leaky bucket technique and effective data rate-matching. Also proposed is a lossless compression mechanism (e.g. run-length encoding (RLE)) for encoding a data bit stream into modem relay packets. An auto-detection method on the non-V.
