What is the technological basis of the SMF?
| |
The SMF is based on proven system components that guarantee high reliability and excellent
performance with quick transmission of trade messages through the system. The system hardware is an HP
NonStop (formerly Compaq, formerly TANDEM) system whose non-stop architecture is geared to applications
with high transaction rates and high availability requirements.
|
|
Who can receive the SMF?
| |
The primary recipients of the SMF are information vendors who further distribute the data via
their own services to end users such as banks, brokers and professional investors. Companies that offer
financial information services to third parties may also receive the SMF.
|
|
What network infrastructure does SIX Exfeed provide?
| |
SIX Exfeed offers two redundancy-enabled 10/100/1000Mbps LAN ports on a dedicated LAN segment per
customer, firewalled against SIX Exfeed's internal networks.
|
|
How to connect to this LAN?
| |
The customer may freely choose how to connect to this private LAN segment. SIX Exfeed recommends two
private WAN links provided by two different carriers.
COLT Telecom Group Ltd, Swisscom Fixnet AG and Verizon Business have
inhouse POPs at SIX Exfeed's premises.
|
|
Does SIX Exfeed allow other network providers?
| |
Connectivity may also be established through a wholesale service offered by a provider of the
customer's choice (e.g.
BT Radianz, SAVVIS Inc. or one of the companies listed above). Where required, SIX Exfeed
provides collocation space for the customer or its service provider to host its WAN equipment.
|
|
Are SIX Exfeed's Market Feeds available via the Internet?
| |
SIX Exfeed does not currently provide VPN facilities or Internet-based access to its market data
feed systems.
|
|
What are SIX Exfeed's recommendations regarding network performance?
| |
A bandwidth of 2Mbps or above is recommended.
|
|
Does SIX Exfeed allow multiple connections?
| |
Each customer is assigned one or more
"feed IDs" and one TCP port per feed ID. Only one connection may be established to a single feed
ID (or TCP port), but multiple feed IDs may be accessed simultaneously. A customer may choose to run multiple
network links, in which case it is assigned a corresponding number of feed IDs and IP address ranges.
|
|
Is it possible to receive SMF/PEX/QMF data via a single IP address?
| |
SIX Exfeed's market-feed systems are made available as a set of individual virtual IP addresses, one
per data product (SMF, PEX, QMF). In order to avoid possible conflicts with internal private IP addressing,
SIX Exfeed uses IP addresses that are officially registered with
RIPE/IANA. Each customer is provided with a set
of IP address ranges that it can use when communicating with SIX Exfeed's market data feed systems. These
addresses are also officially registered with RIPE/IANA.
|
|
Do the SMF and/or PEX-MF provide the
"accumulated volume" of equities' closing
auctions?
| |
Such volume readings are not available as separate figures. However, they can be deduced by
adding up all trade messages generated after
5.30 pm CET that contain
<05>L;O#volume##timestamp. This provides the accumulated volume for the closing
auction.
