First, you could run multiple httpd server processes (the listening processes) each bound to the same port and IP address; this action scales your httpd server process up to 16 processors.

Figure 1-2 on page 1-8 shows transparent network scalability on multiple hosts. The other way of achieving transparent network-level scaling is to use DNS roundrobin address rotation where one DNS name server process returns different IP addresses for a given resource service.
Networking on Integrity NonStop Servers Integrity NonStop Server Networking Compared to Other Platforms that all the web server processes are accessing up-to-date information. In a NonStop server environment, those n hosts can be consolidated onto a single system and have access to a shared database on that same system.

You configure NonStop TCP/IPv6 with round-robin filtering enabled in the Guardian environment and the OSS environment inherits the DEFINE that establishes the environment.
Networking on Integrity NonStop Servers Integrity NonStop Server Networking Compared to Other Platforms Ethernet Failover: Fault-Tolerant Connectivity NonStop TCP/IPv6 provides failover at the adapter level by using a feature called Ethernet failover. Ethernet failover allows a second Ethernet interface to take over connections from another interface if the other interface fails.

To have application isolation on specific interfaces in the NonStop TCP/IPv6 environment, you must configure the NonStop TCP/IPv6 subsystem to use LNP.

2 Networking Concepts This section provides a brief overview of networking concepts including the following topics: • • • • • • • • • Address Resolution Name Resolution on page 2-2 Allocation of IP Addresses on page 2-3 Routers on page 2-3 Switches on page 2-4 Gateways on page 2-4 Network Interface Name on page 2-4 Firewalls on page 2-4 IPv6 on page 2-5 For more detailed information about Internet concepts and services, see the TCP/IP Configuration and Management Manual.
Networking Concepts Name Resolution Name Resolution For convenience, hosts are often referred to by name; in addition, for the world wide web, universal resource locators (URLs) locate a website location. The process of finding the IP address associated with either a host or a URL is a process of name-toaddress mapping, is also called name resolution.
Networking Concepts Allocation of IP Addresses You also need to create a set of ASCII files on each system which contains the addressing information the system needs. Instructions for creating these files are in the TCP/IP Configuration and Management Manual. Once you have configured the domain name services, the network can access the node using the node’s domain name and the domain name service routines will resolve the domain name to the node’s IP address.
Networking Concepts Switches Switches A switch receives messages from various devices on the network and routes the messages over the network to their appropriate destinations. The public telephone network provides the most obvious example of the use of switching, but switches are widely used in private networks as well. Gateways Networks that use different types of hardware and different protocols, such as TCP/IP and OSI, can communicate with each other through a gateway.
Networking Concepts IPv6 it. Administrators for firewalls managing the connectivity for a large number of hosts have a heavy responsibility. IPv6 The IPv6 protocol extends the IP address to 128 bits compared to the 32 bits of IPv4 addresses.
