EGD生产的一次延迟（以及可能的消耗）如果超过24个SRTP服务器连接已启动同时如果同时建立超过24个SRTP服务器连接，则EGD每次连接的生产可能会在第24天之后短暂延迟通电后首先进行连接。如果EGD消耗加速度已禁用，则EGD消耗也将延迟。仅延迟在之后首次建立SRTP服务器连接时发生一次通电。前24个SRTP服务器连接没有延迟，不再支持旧参数名称；使用过时参数名称将导致配置处理错误和以太网异常（条目=2，条目2=06）。
HIMA F7123产品颜色使用过时参数名称的现有AUP文件必须更改为使用新的参数名。SRTP应用程序超时必须适应网络连接开销SRTP通道内的应用超时还包括建立并维护底层网络和SRTP连接。示例正在为新通道建立TCP连接，建立与远程设备的通信，以及通道期间的TCP重新传输操作。如果TCP连接建立或维护所需的时间超过用户指定的通道应用程序超时值，应用程序将发生超时。通道应用超时是临时错误；海峡继续运行。操作系统网络堆栈挂起与连接关闭后的一段时间。此时间段适用于关闭的发起方，它几乎总是客户端。这一次被称为“TCP延迟期”。一旦TCP延迟期到期（60在当前操作系统实现中，TCP资源被释放。使用客户端通道的应用程序开发人员需要了解这种行为在设计逻辑时。有限数量的TCP资源分配给客户端通道，以及如果通道连接的上下速度如此之快资源耗尽后，应用程序可能不得不等待TCP资源释放以建立另一个客户端通道（COMMREQ状态为如果当前没有可用的TCP资源，则返回0xA890；应用程序应等待并重试）。
One-time delay of EGD Production
(and possibly Consumption) if
more than 24 SRTP Server
Connections are started
simultaneously
If more than 24 SRTP Server connections are established simultaneously, EGD
Production may be briefly delayed for each connection after the 24th when the
connections are first made after power is applied. If EGD consume acceleration
has been disabled, then EGD Consumption will also be delayed. The delay only
occurs once when the SRTP Server connection is established for the first time after
Powerup. No delay is experienced for the first 24 SRTP Server connectionsThe old parameter names are no longer supported; use of an obsolete parameter
name will result in a configuration processing error and an Ethernet exception
(Entry = 2, Entry 2 = 06).
Existing AUP files using the obsolete parameter names will have to be changed to
use the new parameter names.
SRTP application timeouts must
accommodate network connection
overhead
The application timeouts within SRTP Channels also include the time needed to
establish and maintain the underlying network and SRTP connection. Examples
are establishing the TCP connection for a new channel, establishing
communication with the remote device, and TCP retransmissions during Channel
operations. If the time needed for TCP connection establishment or maintenance
exceeds the user-specified channel application timeout values, an application
timeout will occur. Channel application timeouts are temporary errors; the channel
continues to run.The OS Network stack hangs on to the TCP resources associated with a
connection for a period of time after the connection is closed. This time period
applies to the initiator of the close, which is almost always the client side. This time
is referred to as the “TCP Linger Period”. Once the TCP Linger Period expires (60
seconds in the current OS implementation), the TCP resources are released.
Application developers using client channels need to be aware of this behavior
when designing their logic. A finite number of TCP resources are allocated to client
channels, and if channel connections are brought up and down so fast that these
resources are depleted, then the application may have to wait until a TCP resource
frees up in order to establish another client channel (a COMMREQ Status of
0xA890 is returned if no TCP resources are currently available; application should
wait and try again).
