POSTILION REAL-TIME SYSTEM 2
Research on postilion Real-time System
The primary purpose of an active/active architecture for most card network providers,
banks as well as payment processors is to achieve a guarantee response time, load balancing as
well as improve throughput. Adopting global card network providers that process the transaction
for great net-worth clients across countries in the middle east and north Africa within their
postulation payment switch environment was essential in the management of their grown
transaction volume without delay or interruption. This paper, therefore, discusses how to send
and receive payment using a Real-time Postilion system.
Postilion can be described as a switch that links banks and credit unions, and it provides a
banking switching software that routes financial transactions (Sabri and El Kamoun, 2013, pp.
321-325). The postilion switch software server is designed into a relatively simple style, which is
sales flows to their intended destination via the switch. Postilion switch can be set up in an
active/active environment to warrant higher network availability of the POS plus ATM. This
enables the continuous flow of transactions through a postilion switch, exception of a case where
a set threshold is exceeded with the transaction volume or a problem exists at a particular path,
whereby a secondary route exists. Existing architecture mostly used as part of a service level
agreement (SLA) /disaster recovery (DR) plan.

Monitoring transactions within the postilion active/active environment is quite
overwhelming. In trying to watch each postilion server, someone swivels the head to catch up
with what is happening on each reporting screen (Yi, Guo, Li, and Huang, B., 2013, p. 88710K).
In this case, identifying precisely the type of transaction that might be causing problems in the
prior occurrence of the significant slowdown as well as failure, can be nearly impossible—
calling for the need to deploy transaction-level monitoring solutions that effectively monitor
complex payment ecosystem –in real-time, which is as useful as the postilion active/active
architecture itself.
In sending and receiving payment messages, authorizations, financial transactions,
reversal network messages using postilion system requires the use of networking infrastructure
such as Electronic Funds Transfer (EFT)networking processing in processing transaction from
the traditional credit card (Zhu, Zhang, Zeng, and Liu, 2014, pp.1007-1017). EFT provides
account information and for account-to-account transfer, bill payment, credit, purchase, debits as
well as other purposes. The card information received includes the card number, cardholder
