WHAT KIND OF WIRELESS SUPPORT DOES THE ALTEON APPLICATION SWITCH OFFER?
Wireless Application Protocol (WAP) is an open, global specification for a suite of protocols designed to allow wireless devices to communicate and interact with other devices. It empowers mobile users with wireless devices to easily access and interact with information and services instantly by allowing non-voice data, such as text and images, to pass between these devices and the Internet. Wireless devices include cellular phones, pagers, Personal Digital Assistants (PDAs), and other hand-held devices. WAP supports most wireless networks and is supported by all operating systems with the goal of inter-operability. A WAP Gateway translates Wireless Markup Language (WML) – which is a WAP version of HTML–into HTML/HTTP so that requests for information can be serviced by traditional Web servers. To load balance WAP traffic among available parallel servers, the switch must provide persistency so that the clients can always go to the same WAP gateway to perform WAP operation. The Alteon Application Switch OS allows you to configure the Alteon Application Switch to select a WAP gateway for each client request based on one of the following three methods:
WHAT IS IBM’S ENTERPRISE WORKLOAD MANAGER AND IBM’S SASP PROTOCOL?
IBM’s Enterprise Workload Manager Enterprise Workload Manager (EWLM) is a product in the IBM Virtualization Engine Suite for Servers. EWLM dynamically monitor server resources and provides input on load balancing decisions. The Workload Manager takes into account a server’s CPU, storage capacity, and network traffic in any final weighting decisions. The Workload Manager uses an implementation of the SASP protocol to perform this task. IBM’s WLM software allows you to specify end-to-end performance goals for distributed requests. WLM runs on an entity responsible for reporting or managing a group of members. This entity is known as the Domain Manager (DM). DM recommends a weight for each application/server in the group. This weight recommendation is based on the business importance, topology and ability of the system to meet its business goals. This recommended weight helps the application switch make intelligent server load balancing decisions. DESCRIBE SUPPORT FOR MICROSOFT WINDOWS TERMINAL SERVICES
Windows Terminal Services refer to a set of technologies that allow Windows users to run Windows-based applications remotely on a computer running as the Windows Terminal Server. The Alteon Application Switch OS v24.0 includes load balancing and persistence options aimed specifically at Windows Terminal Services. Application health checking and load balancing can be performed on Windows Terminal Servers via support for Microsoft’s WTS protocol (RDP). DOES THE ALTEON APPLICATION SWITCH SUPPORT RSTP AND MSTP?
Alteon Application Switch OS v24.0 and onwards supports Multiple Spanning Tree Protocol (MSTP) and Rapid Spanning Tree Protocol (RSTP) as defined in the IEEE 802.1S (MSTP) and 802.1W (RSTP) standards. Rapid Spanning Tree Protocol (RSTP) provides rapid convergence of the spanning tree and provides for the fast reconfiguration critical for networks carrying delay-sensitive traffic such as voice and video. IEEE 802.1s Multiple Spanning Tree extends the IEEE 802.1w Rapid Spanning Tree Protocol through multiple Spanning Tree Groups. MSTP maintains up to 16 spanning-tree instances that correspond to STP Groups 1-16. WHAT IS CONNECTION POOLING (TCP MULTIPLEXING)?
Connection pooling significantly increases network performance by reducing connection load on servers and by avoiding the constant interruption of connection setup and tear down. In a connection pooled environment, a pool of server connections is maintained for servicing client connections. When a client requests a connection, an unused connection is selected from the server pool and used to service the request. When the client request is complete, the server connection is returned to the pool and the client connection dropped. In release v23.0 and higher, this feature will only support the HTTP and HTTPS protocols over TCP with delayed binding enabled. WHAT SECURITY FEATURES DOES THE SWITCH SUPPORT?
The Alteon Application Switch builds security into the fabric of your network by providing unmatched protection against denial of service (DoS) attacks, secure management, secure communications through award winning SSL VPN, SSL acceleration, blocking rogue applications and high availability (including active/active HA) and multi-homing. HOW DOES THE ALTEON APPLICATION SWITCH DEFEND AGAINST DOS ATTACKS?
The Alteon Application Switch uses a number of technologies to defend against DoS attacks. These include:
WHAT SSL INTEGRATION FEATURES ARE AVAILABLE ON ALTEON APPLICATION SWITCHES?

WHAT IS WAN LINK MULTI-HOMING?
WAN link load balancing allows you to configure the Alteon Application Switch to balance user session traffic among a pool of available WAN Links. To handle the high volume of data on the Internet, corporations are using more than one Internet Service Provider (ISP) as a way to increase reliability of Internet connections. Such enterprises with more than one ISP are referred to as being multi-homed. In addition to reliability a multi-homed network architecture enables enterprises to distribute load among multiple connections and to provide more optimal routing. The Alteon Application Switch software provides a solution for enterprises that wish to optimize utilization of Internet connectivity. This comprehensive solution helps enterprises to direct traffic over the best connection to maximize performance, maximize corporate bandwidth investments, and effectively remove existing deployment and management barriers for multi-homed networks.

What is ITM?
Intelligent Traffic Management (ITM) is an application built into the Alteon Application Switch operating system that uses packet consolidation and deep packet inspection to examine, classify and manage application traffic flows. ITM is used to ensure that applications receive the appropriate bandwidth priority and security treatment. Application traffic can be monitored, discarded, prioritized, rate limited, or rate shaped. Unlike many other traffic analysis solutions, ITM inspects and shapes IP traffic at all layers. WHAT ARE ITM’S FEATURES?
WHAT ARE THE COMPONENTS OF ITM?
ITM is comprised of three distinct components; the management module (ASEM client), the processing module, and the reporting module (ASEM server). The processing module runs on the Alteon Application Switch, the management module is a Java applet that runs on ASEM client and the reporting module is a Java application running a server.
