摘要： A method is provided in one example embodiment and includes configuring a network element for load balancing based on input provided by a mobile gateway, where the configuring includes selecting an instance of a service flow router control function (SFR-C) at the network element based on an Internet protocol (IP) address assigned to a subscriber. The subscriber flow rules can be provided to a service flow user plane of the network element. The configuring may also include selecting a subscriber service proxy (SSP) based on a particular load balancing criterion, where a forwarding plane of the network element is configured based on the subscriber flow rules, and where a return message is communicated to the SFR-C that includes a particular IP address of the selected SSP.

摘要： Channel quality of an airlink is assessed at an edge router of a radio-access communication network. Based on the assessment, the cause of lost data is determined to be due to traffic congestion or due to poor channel quality. In the latter case, congestion recovery/avoidance processes of a transport protocol of over a spliced transport connection can be overridden to avoid unnecessary limitations to data flow.

摘要： Methods and systems for providing a dynamic and real time load factor that can be shared with other network elements is disclosed. The load factor can be used in determining the relative load among a set of network elements and in distributing new sessions requests as well as existing session on the set of network elements. The load factor can also be used for determining to which network element a user equipment is handed off. The dynamic load factor can also be shared amongst network elements to determine how the load is balanced among the network elements, such as a mobility management entity (MME).

摘要： When mobile node is connected to an access point outside the private network, a tunnel is formed between the mobile node and a home agent on the private network for the transfer of packets. When, the mobile node roams into a region accessible to the private network, the mobile node is connected to the private network using a private network access point while maintaining the tunnel between the mobile node and the home agent.

摘要： A robust IP/UDP/RTP header compression mechanism is provided to correctly reconstruct IP/UDP/RTP headers in the presence of packet losses and errors of unreliable networks. The header compression mechanism may include a compressor/de-compressor implemented for operation similarly to RFC 2508 but designed specifically to address robustness when employed in lossy and error-prone networks. The robust header compression scheme requires that, when a second-order difference of a field is non-zero, not only a particular RTP packet whose second-order difference is non-zero is sent with the new first-order difference, but also those following packets are also sent with the new first-order difference as long as: (a) a period pre-determined by factors such as channel characteristics (e.g., link round-trip time RTT/inter-packet separation); or (b) a positive confirmation is received by the compressor that the new first-order difference has been correctly received. In addition, during a period of communicating with the new first-order difference, if the corresponding RTP field changes again with non-zero second-order difference, the “new” first-order difference is combined with the original first-order difference such that the two first-order differences may be appended together as a simple means of communicating the two first-order differences reliably.

摘要翻译： 在存在分组丢失和不可靠网络的错误的情况下，提供了稳健的IP / UDP / RTP头压缩机制来正确地重建IP / UDP / RTP报头。 报头压缩机制可以包括类似于RFC 2508实现的用于操作的压缩器/解压缩器，但专门设计用于在有损和易错的网络中使用时解决鲁棒性。 鲁棒的报头压缩方案要求当字段的二阶差异不为零时，不仅以二阶差异为零的特定RTP分组与新的一阶差异一起发送， 只要：（a）由诸如信道特性（例如，链路往返时间RTT /分组间分离）的因素预先确定的时间段，则还发送新的一阶差分的后续分组; 或（b）压缩机接收到正确接收到新的一阶差分的肯定确认。 另外，在与新的一阶差的通信期间，如果相应的RTP字段再次以非零二阶差进行改变，则将“新”一阶差与原始一阶差相结合， 两个一阶差分可以作为将两个一阶差分可靠地通信的简单方法附加在一起。

摘要： A system may provide connectivity service in a multi-tenant network. A first node in the multi-tenant network can receive data packets, each of the data packets identifying one of a plurality of tenant devices. The first node can determine an Internet Protocol (IP) address associated with each of the data packets. The first node can determine a Virtual Local Area Network Identifier (VLAN ID) based on the IP address, the VLAN ID being a unique identifier of a respective one of the tenants. The first node can add the VLAN ID of a corresponding one of the tenants into a header of each of the data packets. The first node can transport the data packets to a second node in the multi-tenant network via a multi-tenant network tunnel protocol.
