摘要： The subject matter described herein includes methods, systems, and computer program products for load balanced and symmetric SPF path computations for VoIP traffic engineering. One method includes advertising an output interface cost in a first direction over a first network segment between a source IP device and a destination IP device that is different from an output interface cost in advertised in a second direction over the first network segment. A plurality of available network paths between the source IP device and the destination IP device is identified. A path cost is calculated for each of the available network paths from the source IP device to the destination IP device. Calculating a path cost includes, for paths that include the first network segment, substituting the output interface cost advertised in the first direction with the output interface cost advertised in the second direction. The path costs are ranked based on the calculated costs. A lowest cost path is selected from the ranked paths. Both directions of a media session are assigned to the lowest cost path.

摘要： Methods, systems, and computer program products for multipath Shortest-Path-First (SPF) computations and distance-based interface selection for VoIP traffic are disclosed. According to one method, a multi-path router instance associated with a plurality of network interfaces in a source IP device is provided. A cost is assigned to each of a plurality of internal segments between the multi-path router instance and the network interfaces associated with the multi-path router instance. An aggregate cost is calculated for each of a plurality of traffic paths originating at the multi-path router instance in the source IP device and extending through each of the network interfaces associated with the multi-path router instance to a destination IP device in the network. A list of IP paths is generated, and the paths in the list are ranked based on the calculated cost. Traffic is sent from the source IP device over at least one of the paths in the list. The path costs and rankings are updated in response to segment cost changes.

摘要： Methods, systems, and computer program products for implementing automatic protection switching for media packets, such as ATM cells or IP packets that carry media content, in a device that includes an Ethernet switching fabric are disclosed. According to one method, first and second packet network interfaces of the device are configured to function as working and protection APS interfaces. At least one of a media processing resource and an Ethernet switch fabric of the device are configured to replicate egress media packets from the media processing resource to the working and protection APS interfaces. Egress media packets from the media processing resource are forwarded to the working and protection APS interfaces via the switch fabric. Ingress media packets received at the working APS interface are forwarded to the media processing resource via the Ethernet switch fabric. Media packets received at the protection APS interface are discarded.

摘要： Methods and systems for classifying incoming and/or outgoing packets to sessions in a media gateway store session identifiers for active sessions in a media gateway in a memory. Each session identifier is a combination of a local network address, a local port number, a remote network address, and a remote port number for the session. Alternatively, each session identifier is a combination of a local network address and a local port number. An incoming and/or outgoing packet is classified to one of the active sessions by using network address and port number information from the packet to perform a lookup for a corresponding session identifier in the memory.

摘要： Methods and systems for per-session dynamic management of media gateway resources are disclosed. According to one method, the logical and physical resources in a media gateway are divided and dynamically managed at the Transport Layer (i.e. OSI Layer 4), which results in finer granularity than managing such resources statically at the Data Link Layer (i.e. OSI Layer 2) or Network Layer (i.e. OSI Layer 3). Voice-processing resources provided by voice server cards may be pooled into a common pool available to all external networks. For each new call/session, the dynamic resource manager of the media gateway dynamically allocates a voice chip from the pooled voice processing resources, and assigns a logical resource identifier (e.g. a local IP and local UDP pair) to the session. When a network interface card receives incoming voice packets, it checks the destination IP and UDP and optionally the source IP and UDP to find out, and forward voice packets to, the voice chip assigned to the session.
摘要翻译：披露了媒体网关资源的每会话动态管理的方法和系统。根据一种方法，媒体网关中的逻辑和物理资源在传输层（即OSI层4）处被划分和动态管理，这导致比在数据链路层静态地管理这样的资源更精细的粒度（即OSI层2 ）或网络层（即OSI第3层）。由语音服务器卡提供的语音处理资源可以汇集到可用于所有外部网络的公共池中。对于每个新的呼叫/会话，媒体网关的动态资源管理器从池化的语音处理资源动态地分配语音芯片，并且向会话分配逻辑资源标识符（例如本地IP和本地UDP对）。当网络接口卡接收到传入的语音数据包时，它检查目标IP和UDP以及可选的源IP和UDP来查找分配给会话的语音芯片的语音数据包。

摘要： A method and apparatus for collecting and processing line performance data transmitted over cables, e.g., Y-cables, is disclosed. The present invention applies a method based on specific performance measurements, specific measurement time intervals, and compare results from different measurement time intervals to produce a “signature” that indicates deteriorating performance of a particular Y-cable. Once a “signature” is detected, the method will proactively and automatically generate a trouble ticket to trigger the dispatch maintenance staffs to service the cable, e.g., to perform the replacement of the Y-cable in question, thus completing the predictive maintenance process. A trouble ticket is a record used to report and manage the resolution of network related problems.
