    Abstract: A method, system and computer program product are described for managing network communications to a Session Initiation Protocol (SIP) server capable of SIP processing using a SIP stack. A data packet is received from a network device. It is determined, from the data packet, whether the network device is a device recognized by the SIP server. Responsive to this determination, and before SIP processing using the SIP stack, it is determined whether the data packet conforms to a permitted configuration. The permitted configuration includes that data of the data packet indicates an unfragmented User Datagram Protocol (UDP) packet and that data indicative of SIP data in the received data packet matches a parsing rule. If the data packet conforms to the permitted configuration, it is passed to the SIP stack, if not it is discarded.

    Abstract translation: 描述了一种方法，系统和计算机程序产品，用于管理能够使用SIP堆栈进行SIP处理的会话发起协议（SIP）服务器的网络通信。 从网络设备接收数据分组。 从数据分组确定网络设备是否是由SIP服务器识别的设备。 响应于该确定，并且在使用SIP堆栈的SIP处理之前，确定数据分组是否符合允许的配置。 允许的配置包括数据分组的数据指示未分片的用户数据报协议（UDP）分组，并且指示接收的数据分组中的SIP数据的数据与解析规则匹配。 如果数据包符合允许的配置，则将其传递给SIP堆栈，否则丢弃。

    Abstract: Measures for enabling media bypass of one or more session border controllers (SBCs) in a telecommunications network which includes a plurality of SBCs. An SBC receives an inbound offer message requesting setup of a media session between an originating endpoint device and a terminating endpoint device. The SBC transmits an outbound offer message to an ensuing SBC, wherein the originating endpoint device address comprised in the inbound offer message is re-written with an SBC address in the outbound offer message. The SBC receives an inbound answer message including a terminating endpoint device address. In response to receipt of the inbound answer message, the SBC transmits an outbound answer message to the originating endpoint device without re-writing the terminating endpoint device address, whereby the SBC and the ensuing SBC are bypassed in the media path for the media session.

    Abstract translation: 在包括多个SBC的电信网络中实现一个或多个会话边界控制器（SBC）的媒体旁路的措施。 SBC接收到请求在始发端点设备和终止端点设备之间建立媒体会话的入站报价消息。 SBC向接下来的SBC发送出站报价消息，其中包括在入站报价消息中的始发端点设备地址被重新写入出站报价消息中的SBC地址。 SBC收到包含终止端点设备地址的入站应答消息。 响应于接收到入站应答消息，SBC向始发端点设备发送出站应答消息，而不重写终止端点设备地址，由此在用于媒体会话的媒体路径中绕过SBC和随后的SBC。
