Citrix的带宽消耗测试
从右图可以看出,应用的
带宽消耗和操作有关,有
些操作或模块会突然传输
3000K/分钟的数据(深蓝
色曲线),如果这时网络
无法保证带宽,给用户带
来的直接感受就是操作变
得很慢,而对应的CITRIX
带宽消耗(浅蓝色)一致
稳定在10K左右。

However, the post login scan would apply the
access policies and may restrict access based
on the fact that the machine is not identified. Appropriate action can be taken, such as restricting the functionality available, offering
help, or remedial attention.
Note that the application list
presented may be restricted based
on the policies applied.
The user is offered restricted access, which
does not allow for downloading or opening
