产品详细资料
SRTP信道操作为每个SRTP信道提供两个信道状态位,一个数据传输位和一个信道错误位。有关状态位及其操作的详细信息,请参阅2.6节,监测以太网接口状态位。8.2.4冗余系统中的SRTP信道命令当配置为冗余IP操作时(参见节:了解更多信息),只有活动单元建立并维护用于信道命令的SRTP客户端连接。备份单元不执行任何SRTP客户端操作。如果尝试SRTP客户端操作,则会向本地逻辑程序返回COMMREQ错误状态。当以太网接口从活动状态变为备份状态时,它会断开所有SRTP客户端连接及其底层TCP连接。由于断开TCP连接可能需要一些时间,因此冗余系统应为使用冗余IP地址的每个连接保留一个备用SRTP客户端连接。这将防止在与新的活动单元建立新的SRTP客户端连接时出现临时资源问题,而与旧的活动单元的先前连接正在被断开。
SRTP channels operation provides two Channels Status bits for each SRTP channel, a Data Transfer bit and a Channel Error bit. For details of the status bits and their operation, refer to Section 12.6, Monitoring the Ethernet Interface Status Bits. 8.2.4 SRTP Channel Commands in a Redundant System When configured for Redundant IP operation (see Section 1: for more information), only the active unit establishes and maintains the SRTP Client connections used for the Channel commands. The backup unit does not perform any SRTP Client operations. If SRTP Client operation is attempted, a COMMREQ error status is returned to the local logic program. When the Ethernet interface changes from active to backup state, it takes down all SRTP Client connections and their underlying TCP connections. Because it can take some time to take down a TCP connection, the Redundant system should reserve a spare SRTP Client connection for each connection using the Redundant IP address. That will prevent temporary resource problems when establishing new SRTP Client connections to the new active unit while the previous connections to the old active unit are being taken down.
