Chapter 14 Load Balancing in the P333R-LB

•Single Virtual Service for multiple VIPs - PIP enables mapping several VIPs to a single application. The Virtual Services, configured for each VIP, point to the same Real Server Group as well as to the same Real port. This enables emulating a configuration where different servers, each with a different IP address, provide the same service.

•Direct Client-Real Server session access - Full NAT enables sessions to the VIP as well as direct sessions between the Clients and Real Servers to traverse the same P333R-LB. The sessions to the VIP undergo Full NAT, while direct Client-Real Server sessions are routed by the P333R-LB without NAT. Such an application is not possible when implementing Half NAT.

•Mapping different Virtual Services to the same port on the Real Servers - Each service has its own PIP, enabling different flows to the same port.

You prepare banks of IP address ranges and associate each Virtual Service with a bank.

Note: You can create 64 banks of PIP addresses, with a total of 32,768 PIP addresses.

If you haven’t configured a bank for a Virtual Service, P333R-LB uses Half NAT load balancing for that Virtual Service.

With Full NAT, responses made by the Real Server are forced to pass through the P333R-LB, where the Real Server IP is replaced with the Virtual Server IP, and the PIP with the client’s original IP before forwarding them to the clients.

Note: Configure the PIP addresses on a dedicated subnet. If you configure a local interface on the PIP subnet, it is advertised throughout the network by the Routing Protocols as belonging to that router, like all other subnets. If no Local Interface is configured on the PIP subnet, Static Routes should be configured to reach that PIP subnet.

Note: The P333R-LB does not answer to ARP requests, or to pings on the subnet.

Note: You can not configure Full NAT for Active FTP Virtual Services.

P333R-LB specifications

The Avaya P333R-LB is a robust and versatile switch that is part of Avaya's portfolio aimed at enterprise networking solutions. This switch is designed to enhance the performance and scalability of network infrastructure while ensuring high availability and reliability.

One of the main features of the P333R-LB is its Layer 3 switching capability, which allows for efficient routing within an organization's network. This capability is particularly beneficial for organizations with multiple VLANs, as it simplifies the routing process and ensures that data packets are transmitted in the most efficient manner possible.

The P333R-LB is equipped with advanced Quality of Service (QoS) features to prioritize traffic based on the type of application being used. This ensures that critical applications, such as VoIP and video conferencing, receive the necessary bandwidth and low latency required for optimal performance. Additionally, it supports both IPv4 and IPv6 protocols, making it adaptable to a variety of networking environments.

Another important feature of the Avaya P333R-LB is its stackable design. This allows multiple switches to be interconnected, creating a single logical unit. This stacking capability not only simplifies management but also increases overall network capacity and redundancy. In case of a hardware failure, the stack can continue operating without interruption, maintaining network integrity and service continuity.

The switch also integrates advanced security features, including support for MAC filtering, access control lists, and port security. These features help to safeguard network resources from unauthorized access and potential threats. Moreover, the P333R-LB supports 802.1X port-based authentication, which adds an additional layer of security during user access to the network.

The Avaya P333R-LB comes with multiple Gigabit Ethernet ports, allowing for high-speed connectivity to devices such as servers, workstations, and IP phones. This ensures that all devices on the network can communicate effectively, supporting the demands of modern enterprise environments.

For management and monitoring, the P333R-LB offers a user-friendly web interface along with SNMP support, enabling network administrators to easily configure settings and monitor network performance. This simplicity in management is crucial for IT teams that need to ensure optimal network performance while minimizing downtime.

In summary, the Avaya P333R-LB is a feature-rich, scalable, and reliable switch that meets the needs of demanding enterprise networks. With its advanced technologies, QoS support, stackable design, robust security features, and high-speed connectivity options, the P333R-LB is positioned to support a wide range of applications and enhance overall network performance.
