IP Differentiated Services Diffserv | VBrick Systems VB4000, VB6000

Streaming Video Basics

Host Names has an Address Mode parameter. This configuration parameter allows the user to specify how the address is to be configured: IP Address or Host Name. If Address Mode is set to "Host Name," the IP address field becomes a status field and is used to report the IP Address of the configured Host Name. Likewise, if Address Mode is set for "IP Address," the Host Name field is used to report the Host Name of the configured IP Address. If the configured IP address is multicast, the Host Name field will be blank. The following rules apply:

•The following addresses can be configured using Host Names: Encoder network destination address

Pump network destination address Decoder network receive address Recorder network receive address Passthrough dedicated address

•Multicast addresses cannot be configured using Host Names.

•The Management SAP Transmit parameter of the referenced VBrick has to be set to Enabled for this feature to work.

•The Host Name feature does not work if the appliance is in edit mode. Please exit Edit mode when finished configuring the appliance.

IP Differentiated Services (Diffserv)

Type of Service settings control the level of priority a service or source receives while traveling through a network. VBrick supports setting the IP TOS (Type of Service) in accordance with RFC-791, RFC-1112 and RFC-2474 (Differentiated Services Field in the IPv4 Header). You can set the Type of Service field in the IP header to any value, decimal 0 to 255.
