摘要： A method, system, and computer-readable medium for transmitting voice over multiprotocol label switching is provided. A packet that includes layer 3 and layer 4 headers is received. A label that identifies a label switched path in the packet is inserted, and a stream identifier is generated. The stream identifier is associated with at least a portion of content of the layer 3 and layer 4 headers. The layer 3 and layer 4 headers are removed from the packet, and the stream identifier is inserted into the packet. Additionally, methods, systems, and a computer-readable medium for processing a voice over multiprotocol label switching frame that excludes layer 3 and layer 4 headers are provided.

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： Methods and systems for automatic denial of service protection in an IP device are disclosed. Packets are received at a network interface of an IP device, the packets being addressed to a network address of the network interface. The packets addressed to the network interface of the IP device are forwarded to a processor in the IP device. The processor determines whether the packets violate a rate-based policing policy of the IP device. In response to determining that the packets violate the rate-based policing policy, source identifying information associated with the packets is added to an access control list in the IP device. Packets matching criteria in the access control list are prevented from being forwarded to the processor in the IP device.

摘要： Methods and systems for measurement-based call admission control in a media gateway are disclosed. A request for establishing a new voice-over-IP (VoIP) call for sending and receiving voice over IP packets in a media gateway is received. The request indicates a required bandwidth for the new call. Bandwidth utilization of at least one Internet protocol (IP) network interface for sending and receiving voice over IP packets in the media gateway is determined. The media gateway determines whether to admit the new VoIP call based on the determined requested bandwidth for the new call and the determined bandwidth utilization for at least one of the IP network interfaces.

摘要： Methods and systems for per-session traffic rate policing in a media gateway (200) include receiving voice over IP (VOIP) packets at a media gateway (200) where it is determined whether each VOIP packet is associated with an existing VOIP session in the media gateway (200). A per-session traffic rate policing policy is applied to the packets associated with the existing sessions in the media gateway (200). In response to determining that a packet violates the per-session traffic rate policing policy, the packet is discarded.

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）处被分割和动态管理，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： Method and systems for detecting IP route failure using a request-reply protocol, such as address resolution protocol (ARP), and for dynamically re-routing VoIP sessions in a VoIP device in response to failure of an IP route are disclosed. A plurality of IP routes (106) are established between a first VoIP device and a second VoIP device. VoIP sessions are assigned to the IP routes. ARP is used to detect a Failure of an IP route. In response to detecting a failure of at least one IP route (108), VoIP sessions are rerouted from the failed IP route to an alternate IP route (110).
