5. IP network
2. Communication with the infrastructure services used (NTP, SIP, etc.) must be
possible in an unlimited manner that is transparent in regard to protocols.
3. Insofar as the SystemOrganizer or ManagementCenter is located outside of a
Flamenco domain, communication must be possible between the Flamenco do-
mains and this component in an unlimited manner that is transparent in regard to
protocols.
4. Network traffic not listed under Items 1 – 3 must not occur in the Flamenco do-
mains.
5. For a problem-free function of the system components, especial in regard to
voice integration, a functional IPv4 multicast integration is necessary. Within the
Flamenco domains, IGMP in Version 3 must be supported, and IPv4 multicast
routing must be supported in the entire infrastructure.
6. The fulfilment of the requirements on transmission quality within the network
(bandwidth, latency, jitter, packet loss) must be guaranteed through the imple-
mentation of suitable QoS configurations if necessary, refer to chapter 5.4.1
"QoS requirements" on page 29.
7. If a remote maintenance of the system is intended, an unlimited communication
between the remote maintenance station and the Flamenco
nents is required. Terminal devices in the IT infrastructure on which system soft-
ware is running must also be able to be accessed from the remote maintenance
station. The requirements on the transmission quality (Item 6) do not have to be
observed for the remote maintenance station.
An overview of the communication relationships and ports used of the Flamenco
system are located in the appendix of this chapter, refer to chapter 5.4.2 "Communi-
cation relationships in the Flamenco
5.1.3 Network services in the existing infrastructure, NTP
In order for a centralised and precise time source to be available for the entire Fla-
IP
menco system, components of the system can call their time information from an
NTP server. For this purpose NTP Version 2 (unicast, no authentication) is used.
