Special Ip Services; Table 5.4 Priority, Ip Mapping (Protocol / Port) And Arq - R&S M3SR 4100 Series Operating Manual

M3SR Series 4100
• Reduced receive window size
A reduced receive window discourages the sender from sending huge packet bursts
congesting the network. Recommended values are between 4 to 16 x MSS (Maximum
Segment Size), typically 8 x MSS = 3766.
All hosts (endpoints terminating the transport protocol) involved need their settings
to be adapted.

Special IP Services

The IPoA protocol provides support for several predefined IP services running on the radio,
such as
• Text Message Service
• Alarm Service
• GPS Service and
• GPS Immediate Service.
Each of these services can be enabled / disabled in the mission configuration using
R&S RNMS3000 (Radio Network Management System) and has a send priority and an IP
mapping (protocol / port) assigned as listed in Table 5.4.

The send priority order defines the priority among the services, i.e. alarm messages are al-
ways sent before all other services. IP data passed to the IPoA protocol for transmission is
mapped to the services according to their IP mapping configuration, e.g. a UDP packet with
