session-level settings for the relevant media. The first sub-field is the network type, which is a text string giving the type of network. Initially "IN" is defined to have the meaning "Internet". The second sub-field is the address type. This allows SDP to be used for sessions that ...
A software-defined perimeter (SDP) is a way to hide Internet-connected infrastructure (servers, routers, etc.) so that external parties and attackers cannot see it, whether it is hosted on-premise or in thecloud. The goal of the SDP approach is to base the network perimeter on software in...

<session id>是一个数字字符串,所以<username>, <session id>, <network type>, and 为这个会话构成了一个全局的惟一标识符。 <session id>分配的方法是由创建工具来决定的,但建议使用Network Time Protocol(NTP)时间戳来确保其唯一性。 <version>是这个公告的版本号。用于proxy探测同一个session中的几个announc...
Software-defined perimeter (SDP) products are a specific type of network security solution which focus on network segmentation and user authentication. SDP itself is an architecture designed to allow access on a need-to-know basis, meaning every device and user must be verified before accessing eit...
timestamp is used. <nettype> is a text string giving the type of network. Initially "IN" is defined to have the meaning "Internet", but other values MAY be registered in the future (seeSection 8). <addrtype> is a text string giving the type of the address that follows. Initially "...

c=network-type address-type connection-address The network-type parameter is defined as IN for the Internet. The address type is defined as IP4 for IPv4 addresses, IP6 where ttl is the time-to-live value, and number-of-addresses indicates how many contiguous multicast addresses are included ...
specify the RTCP bandwidth independently of the session bandwidth. Using a separate parameter allows rate-adaptive applications to set an RTCP bandwidth consistent with a "typical" data bandwidth that is lower than the maximum bandwidth specified by the session bandwidth parameter. That allows the RTCP...
