3 Introduction to Ravenna Technology
Scope
The information in this chapter is provided as background of the philosophy and technology behind Ravenna.
Overview
Ravenna is a technology for real-time distribution of audio and other media content in IP-based network environments. Utilizing standardized network protocols and technologies, Ravenna can operate on existing network
infrastructures. Ravenna is designed to meet the strict requirements of the pro audio market featuring low latency,
full signal transparency and high reliability.
Ravenna is suitable for deployment in many pro audio market segments including broadcast, live sound, studios
the install market and location music recording. Possible fields of application include (but are not limited to) inhouse signal distribution in broadcasting houses, theaters, concert halls and other fixed installations, flexible setups at venues and live events, OB van support, interfacility links across WAN connections and in production &
recording applications.
In short, it represents a new take on the third generation form of audio interconnect, where the first generation of
interconnect is analogue point-to point copper, the second generation uses digital codes representing the analogue signal, conveyed point to point over copper or fibre-optic cabling and the third generation also employs
digital codes representing the analogue audio but transported as packets over network infrastructure.
Ravenna is very well suited to areas where complex audio routing / mixing systems are deployed. For example; inhouse distribution in broadcasting centres and WAN connections to satellite studios, OB vans, where hook up to
venues with the same infra-structure becomes simple, in venues themselves for local signal distribution and connection to just such OB vehicles when required. For live events and concerts it offers highly flexible temporary
installation possibilities and in theatres, opera houses and houses of worship it can provide low cost local signal
distribution. Notwithstanding all of the above, Ravenna is also an excellent candidate for relatively simple point to
point interconnects such as computer to audio interface.
However, Ravenna, leaving aside the other advantages touted, is an open standard based on the ubiquitous IP
protocol. Specifically, protocol levels on or above layer 3 of the OSI reference model. Since Ravenna is purely based
on layer 3 protocols, it can operate in most existing network environments. Unlike layer 1 or layer 2 solutions, it
does not, in principle, require its own network infrastructure. IP can be therefore be transported on virtually any
LAN and is used as the base layer for communication across WAN connections (including the internet). Although
in most cases Ethernet will be deployed as the underlying data link layer, IP is in general infrastructure-agnostic
and can be used on virtually any network technology and topology. All the protocols and mechanisms used in
Ravenna are based on well established and commonly used methods from the IT and audio industries and comply
with various standards defined and maintained by the international standards bodies.

RAVENNA Network Guide
Basic Components
Ravenna Network Basic Components Example
A Ravenna system requires a carefully configured IP network, a master clock device and any number of Ravenna
enabled I/O nodes. The master clock can be either a dedicated device or any Ravenna node capable of serving as a
grandmaster. The preferred time domain reference is GPS. Simple streaming across a network can be achieved
without any synchronization at all but in pro audio applications tight synchronization between all devices and
streams is absolutely mandatory. While playback synchronization in most applications requires sample accuracy,
one goal for Ravenna is to provide superior performance by offering phase-accurate synchronization as an option
thus rendering separate reference word clock distribution throughout a facility or venue redundant.
Flexibility
The system design approach allows for operation with or without centralized services for configuration / connection management. ALC NetworX recommends that basic device configuration (e.g. initial settings and setup of
audio streams) should be executed via a web interface (http). However other methods may be used in addition or
as an alternative.
Device discovery is accomplished with DNS-SD (via an mDNS or DNS service). In small networks, without DHCP /
DNS servers, the zeroconf mechanism - a fully automatic, self-configuring method - is used for auto-IP assignment
and service advertisement & discovery.
Streams available on the network are represented by SDP records with extended information (i.e. a clock domain
identifier, RTP time stamp association etc.) Clients can connect to streams via RTSP or SDP/http.
Resilience
As you would expect Ravenna supports redundancy. Although modern network infrastructures can be configured
to guarantee a high level of transport security and reliable 24/7 operation for added security there is the option of
full network redundancy. Each Ravenna device can include two independent network interfaces which can be
connected to independent physical networks. By duplicating any outgoing stream to both network links, any destination device will receive the full stream data on both network interfaces independently. If data from one link is
corrupted, or one network link fails completely, the uncorrupted data is still present on the other link. Changeover
in the event of the failure of a network link is automatic.

RAVENNA Network Guide
Streaming
Unicast
Unicast (one-to-one) is used in application scenarios such as an individual stream between two devices (e.g. a
multi-channel stream between a console and a recorder/DAW). This uses a point-to-point connection between
the sender and receiver. Since each additional receiver adds its own individual connection network traffic
increases with every additional unicast stream.
Multicast
Multicast (one-to-many) streaming is used in scenarios where a single source is to be distributed to many potential recipients (e.g. program stream to journalists' desktops). At the sending end this only requires one connection
per stream. Network switches are aware which participants (receivers) should receive any particular multicast and
forward packets only to registered nodes. In multicast set-ups the network traffic only increases on the last (closest
to receiver node) segment(s) of the network path.
Infrastructure
The network infrastructure must be able to transport IP packets and must support a number of standard operating protocols, e.g. RTP/RTPC for streaming since this is used widely and supports a wide variety of standard payload formats. Some of these formats are mandatory for all Ravenna devices, others are optional. For example this
protocol offers the possibility of standard media player applications subscribing to Ravenna streams. Synchronization across all nodes is achieved via the IEEE1588-2008 (PTPv2 Precision Time Protocol). This is another standard
protocol which can be used on IP. PTPv2 provides a means for synchronizing local clocks to a precision as defined
in AES-11. Accurate synchronization can even be achieved across WAN connections when GPS is used as a common time domain.
Quality of Service
For the QoS (Quality of Service) protocol DiffServ has been chosen since it is widely supported by most modern
managed switches. Since other traffic can co-exist with Ravenna on the same network, Ravenna traffic must be on
the fast track. Ravenna packets are assigned a high priority classification to ensure expedited transport across the
network, while other packets with lower priority are treated as best-effort traffic. Even within Ravenna there are
different priorities assigned to different classes of traffic. Synchronization is assigned the highest priority, immediately followed by any real-time media traffic, while control and configuration traffic will be on a lower priority
level. Any non-Ravenna traffic would receive the lowest (standard) priority and be treated as best-effort traffic. Performance and capacity scale with the capabilities of the underlying network architecture.

Connecting Multiple Horus' to the Switch
Once the switch is configured everything is prepared for connecting multiple Horus' to the switch ports.
1. Connect an RJ45 Ethernet patch cable (CAT5E or 6 STP) from the Merging PCIe Ethernet card (NET-MSCGBEX1) to the switch.
2. Connect an RJ45 Ethernet patch cable (CAT5E or 6 STP) from each of your Horus devices Pri (primary) port to
ports on the Switch.
3. Once you power up the Horus’ one of the Horus’ will automatically be chosen as Master PTP and the other
Horus’ will be PTP Slaves.
Note: When several Horus’ are on the same network then one of them will be elevated
automatically to PTP Master and the others configured as PTP slaves (see Horus User
Manual).
4. You are now ready to work in Ravenna mode.
Note: PTP sync does not permit synchronization to word clock or an audio input. However, this is not an issue since all Horus' will be synchronous.
Only one Horus can lock to an external source; it then becomes the PTP master; other
Horus’ switch automatically to PTP slave (see Horus User Manual).
