Abstract: Techniques for separately accounting for multiple transactions in the same data packets communicated over a network using Transport Control Protocol (TCP) include receiving an Internet Protocol (IP) data packet that includes Transport Control Protocol (TCP) payload data. The TCP payload is parsed to determine boundary data that indicates a byte location on a boundary between a first transaction and a second transaction. A byte count that indicates a number of bytes in the TCP payload associated with the first transaction is determined based on the boundary data. Accounting data for the first transaction is determined based at least in part on the byte count. These techniques allow a service gateway to bill separately for different requests and responses carried in TCP data packets, such as those for Hypertext Transfer Protocol (HTTP) and Real Time Streaming Protocol (RTSP).

Abstract translation: 用于单独计算通过使用传输控制协议（TCP）通过网络传送的相同数据分组中的多个事务的技术包括接收包括传输控制协议（TCP）有效载荷数据的因特网协议（IP）数据分组。 解析TCP有效载荷以确定指示在第一事务和第二事务之间的边界上的字节位置的边界数据。 基于边界数据确定指示与第一事务相关联的TCP有效载荷中的字节数的字节计数。 至少部分地基于字节计数确定第一事务的计费数据。 这些技术允许服务网关对TCP数据分组（例如超文本传输​​协议（HTTP）和实时流协议（RTSP））中携带的不同请求和响应进行单独计费。

Abstract: In one embodiment, a method includes receiving one or more packets of a communication session from one or more interfaces, such that the interface is a subscriber interface or a network interface. The method further includes associating the communication session to an end user with a source Internet Protocol (IP) address of the packet if the packet is received from the subscriber interface or to an end user with a destination IP address of the packet if the packet is received from the network interface.
