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： The subject matter described herein includes methods, systems, and computer program products for source-aware IP routing at a media gateway. According to one aspect, a method for source-aware IP routing at a media gateway is provided. The method includes providing a packet including a layer 3 source address and a layer 3 destination address at a media gateway having a source-aware routing table. Using the destination address included in the packet, at least one entry corresponding to the destination address is located in the source-aware routing table, where the located entry contains at least a portion of a source IP address, at least a portion of a destination IP address and routing information including an interface identifier and a next hop identifier. From among the at least one located entry corresponding to the destination IP address information, at least one entry corresponding to the source IP address included in the packet is located. Based on the routing information located in the routing table, the packet is routed to the destination.

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： 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.
