Abstract: In one embodiment, an apparatus comprises logic for optimizing return traffic paths using network address translation (NAT). The logic is operable to receive outbound data from a source node in a source network, and to replace a source address in a source address field in the outbound data with a first address from a first address pool associated with a first connection. The logic is operable to determine that return traffic on the first connection needs to be switched over to a second connection, where a second address pool is associated with the second connection. The logic is operable to generate a mapping that associates the first address with a second address from the second address pool and, based on the mapping, to replace the first address in the source address field in the outbound data with the second address. The logic is also operable to send the outbound data to the destination node over the second connection.

Abstract translation: 在一个实施例中，装置包括用于使用网络地址转换（NAT）来优化返回业务路径的逻辑。 该逻辑可操作以从源网络中的源节点接收出站数据，并且使用来自与第一连接相关联的第一地址池的第一地址来替换出站数据中的源地址字段中的源地址。 逻辑可操作以确定第一连接上的返回流量需要切换到第二连接，其中第二地址池与第二连接相关联。 逻辑可操作以生成将第一地址与来自第二地址池的第二地址相关联的映射，并且基于该映射，以用第二地址替换出站数据中的源地址字段中的第一地址。 该逻辑还可用于通过第二连接将出站数据发送到目的地节点。
