Network architecture

This section presents the details of the SoftExpert Suite network architecture. See the diagram below:

Picture 5 - SE Suite network architecture

As shown in the diagram in Picture 5, the communication between the layers, performed through TCP/IP networks, uses specific protocols for each situation. See below the description of each used protocol:

Components	Protocols and Default Ports
Front End	443: HTTPS
Database (JDBC, Native Client, and Provider)	1521: Oracle
	1433: SQL Server
	5432: PostgreSQL
E-mail	25: SMTP

Table 2 - Protocols and Default Ports used by SoftExpert Suite

▪E-mails are sent from the Web server only.

▪The Firewall must be configured for the internal and external network workstations to have access to the service ports.

▪If an external server is used, the workstation must have access to the file server. Refer to External/Distributed Server section for further details.

Protocols

See below the protocols used by SoftExpert Suite and their purposes:

▪HTTPS is used in requests made by the customer;

▪Native Client, Provider and JDBC are used in requests made to the database (only through the business layer);

▪SMB, NFS are used to view and store documents in a directory(1)(2);

▪SMTP is used for sending notification e-mails through SoftExpert Suite.

▪SAML, LDAP, and NTLMv2 are used to authenticate the users in the SoftExpert Suite.

1 - When using a remote directory (External Server), the HTTPS protocol will be used.

2 - When the system is parameterized to store documents in the directory.

Load Balancing

SoftExpert Suite was designed and developed in a way that layers and services may operate independently. That way, the system is able to operate both in single and multiple servers, thus enabling load balancing.
