摘要： Methods, systems, and computer program products for throttling network address translation (NAT) in a voice over IP device (100,102) are disclosed. According to one method, a plurality of media packets associated with a media session are received at a voice over IP device (100, 102). A NAT learning throttling filter (116) is applied to select the subset of the packets to be used for NAT learning (114) and thereby limit the number of received media packets to be used for NAT learning (114). NAT learning (114) is performed for the session using the packets selected by the NAT learning throttling filter (116).

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

摘要： Methods and systems for providing voice over IP traffic engineering and path resilience using a network-aware media gateway are provided. In a media gateway, voice over IP hosts (H1-H4) are assigned a first set of IP addresses (IPV1-IPV4). Network interfaces (I1-I3) in the media gateway (300) are assigned a second set of IP addresses (IPI1-IPI3) that differ from the first set of IP addresses. Per-interface routers (R1-R3) advertise reachability information from at least one of the voice over IP hosts (H1-H4) via multiple interfaces (I1-I3) and participate in network routing protocols to generate per interface routing tables. Voice over IP path lists (314) may be generated based on the per interface routing tables. Internal costs may be assigned to the associations between the voice over IP hosts (H1-H4) and the interfaces (I1-I3) based on traffic engineering criteria.

摘要： Methods and systems for per-session NAT learning and firewall filtering are disclosed. Media packets associated with a call/session are received and processed at a media gateway. For the first few received media packets associated with a session, the media gateway uses various unique methods to learn the actual source IP address and UDP port assigned to the remote communication terminal by its customer-premises Network Address Translators (NATs) to the media flows of the current session. After the remote IP and UDP are learned, the media gateway reconfigures its firewall filtering function to check both the dynamically learned remote IP and UDP and the locally assigned IP and UDP of the current session. The per-session NAT learning function removes reachability issues in VoIP deployment, and the per-session firewall filtering function enhances security protection in VoIP deployment.

摘要： Method, systems, and computer program products for voice over IP (VOIP) traffic engineering and path resilience using media gateway (300) and associated next-hop routers (R1, R2, R3) are provided. In one example, a media gateway (300) includes multiple media processing hosts (H1, H2, H3, H4) and a multiple network interfaces (I1, I2, I3) separate from the media processing hosts (IPI1, IPI2, IPI3). At least one of the media processing hosts (H1) is reachable via at least two of the network interfaces (I1, I2). Next-hop routers (R1, R2, R3) associated with the network interfaces advertise reachability information regarding the media processing hosts (H1, -H4) to routers in the network (304). The next-hop routers (R1-R3) also participate in network routing protocols to form mulitiple paths between the media gateway (300) and a remote media gateway (302). Costs may be assigned to association between the media processing hosts (H1-H4) and the next-hop routers (R1-R3) for traffic engineering purposes.

摘要： A method of adaptive resource allocation in transmitting data is provided. In particular, the method of the present invention is applicable to scheduling bandwidths using a modified and dynamic weighted round robin process. The method includes the steps of allocating a resource to each of a plurality of data transmitting active connections, the plurality of active connections belonging to more than one class of service. Then the method determines a lender class of service for each active connection from which resources may be reallocated to the active connection, and periodically comparing the resource usage of an active connection to upper and lower thresholds. Borrowing action for resources and returning action of borrowed resources are carried out in response to the current usage exceeding the upper threshold or less than the lower threshold, respectively.
