Abstract: Methods and apparatus for supporting mobility using SCTP are disclosed. In accordance with one aspect of the invention, an SCTP association between a first network device and a second network device may be modified. The SCTP association includes a first set of IP addresses associated with the first network device and a second set of IP addresses associated with the second network device. The first network device establishes the SCTP association between the first network device and the second network device. An SCTP configuration message is then sent from the first network device to the second network device, the configuration message indicating a modification to be made to the SCTP association, thereby enabling the SCTP association to be modified without disconnecting an existing session.

Abstract: The present invention provides a method for evaluating a communication link between a first communication site and a second communication site. The first and second communication sites increment a sent counter and reset a received counter upon sending a message to the other communication site. Each communication site also increments a received counter and reset a sent counter upon receiving a message from the other communication site. When the sent counter exceeds a sent threshold, the communication system site sends an alert that the communication link is down. When the received counter exceeds a predetermined percentage of the other communication site's sent counter, the site sends a message to the other communication site to let the other communication system site know that it is still receiving messages.

Abstract translation: 本发明提供了一种用于评估第一通信站点和第二通信站点之间的通信链路的方法。 第一和第二通信站点在发送消息到其他通信站点时增加发送的计数器并重置接收到的计数器。 每个通信站点也会增加收到的计数器，并在从其他通信站点接收到消息时重置发送的计数器。 当发送的计数器超过发送的阈值时，通信系统站点发送通知链路关闭的警报。 当所接收的计数器超过其他通信站点的发送计数器的预定百分比时，站点向另一个通信站点发送消息，让另一个通信系统站点知道它仍在接收消息。

Abstract: Methods and systems are disclosed for routing callers to agents in a contact center, along with an intelligent routing system. A method for routing callers includes routing a caller, if agents are available, to an agent based on a pattern matching algorithm (which may include performance based matching, pattern matching based on agent and caller data, computer models for predicting outcomes of agent-caller pairs, and so on). Further, if no agents are available for the incoming caller, the method includes holding the caller in a shadow queue, e.g., a set of callers. When an agent becomes available the method includes scanning all of the callers in the shadow queue and matching the agent to the best matching caller within shadow queue.

Abstract: Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means associated with automated discovery of network devices supporting particular transport layer protocols, such as, but not limited to Stream Control Transmission Protocol (SCTP). Packet switching devices automatically discover peer packet switching devices supporting a particular transport layer protocol, and then establish a session using the particular transport layer protocol between them for subsequent use in transporting packets.

Abstract: A method for communicating data in a network environment is provided that includes receiving one or more packets for establishing a communication session in a network and determining which of the packets should be delayed. A selected one or more of the packets are delayed for a designated time interval in order to extend a roundtrip time (RTT) parameter associated with the selected packets. The selected packets are communicated after the time interval has expired.

Abstract: A communication network (100) includes a first server (124) and a second server, such as any of the servers (121-23), connected via a common network (101). First server (124) owns a record data (180) associated with at least one process running for serving a client device (174.) The second server keeps a copy of the record data. First server (124) performs a Hashing function over record data (180) to produce a first Hash value. The second server similarly performs the same or similar Hashing function over the copy of the record data to produce a second Hash value. First server (124) sends the first Hash value to the second server for comparison. If the first Hash value fails to match to the second Hash value, a latest copy of the record data (180) is sent from first server (124) to the second server upon request.

Abstract translation: 通信网络（100）包括经由公共网络（101）连接的第一服务器（124）和诸如服务器（121-23）中的任一个的第二服务器。 第一服务器（124）拥有与至少一个运行用于服务客户端设备的进程相关联的记录数据（180）。第二服务器保存记录数据的副本。 第一服务器（124）对记录数据（180）执行哈希函数以产生第一哈希值。 第二个服务器类似地在记录数据的副本上执行相同或相似的哈希函数，以产生第二个哈希值。 第一服务器（124）将第一哈希值发送到第二服务器进行比较。 如果第一哈希值不匹配到第二哈希值，则根据请求将记录数据（180）的最新副本从第一服务器（124）发送到第二服务器。

Abstract: A method of switching a call to a multipoint conference call includes sending a message (201) from a first terminal (105-T1) to a gatekeeper (102) which provides address translation and control access to a shared network medium (101). The call is initially established as a point to point communication between first terminal (101) and a second terminal (105-TN) over shared network medium (101) while complying with H.323 standard. Message (201) contains a request for the multipoint conference call. The method furthermore includes selecting a multipoint control unit (104) connected to shared network medium (101) to allocate resources for the multipoint conference call, and then switching the call to the multipoint conference call via the allocated resources. Thereby, the initial call is switched to a multipoint conference call without interrupting the initial call.

Abstract translation: 将呼叫切换到多点会议呼叫的方法包括从第一终端（105-T1）发送消息（201）到提供对共享网络媒体（101）的地址转换和控制访问的网守（102）。 呼叫最初被建立为在符合H.323标准的同时在共享网络介质（101）之间的第一终端（101）和第二终端（105-TN）之间的点对点通信。 消息（201）包含对多点电话会议的请求。 该方法还包括选择连接到共享网络介质（101）的多点控制单元（104）以分配用于多点会议呼叫的资源，然后经由所分配的资源将呼叫切换到多点会议呼叫。 因此，初始呼叫被切换到多点电话会议而不中断初始呼叫。
