Designed for enterprise mission critical deployment, HP-UX 11i networking software is built on a core consisting of the TCP/IP stack and STREAMS software and is engineered to achieve an unprecedented level of reliability, scalability, adaptability and performance.

• Reliability. With industry leading security technology and integrated fault detection, correction and recovery capabilities, the core provides reliable and trustworthy network communications and services.
• Adaptability. With intelligent automatic configuration, dynamic optimization and self-tuning capabilities, it gracefully adapts to different networking conditions from noisy low bandwidth wireless environments to high bandwidth high throughput datacenter environments.
• Scalability. Designed for scalability, it can gracefully scale up from 1 processor to 256 processors, from megabytes to gigabytes of memory, from 10 Base T to 4 Gigabit Ethernet from the classic IPv4 to the next generation IPv6.
• Performance. Based on a deep understanding of system performance and implemented with an exceptional level of precision, a suite of kernel optimizations enables HP-UX 11i to achieve the best SPECweb and SPECwebSSL results in the industry with a score of 23000 and 9060 respectively. (July 2004)

Continual investment is made to ensure that the core maintains its competitive advantage. The latest additions to the core include IP over InfiniBand; improved handling of sporadic bursts of traffic through new congestion window revalidation methods; increased communication throughput with Linux systems using mechanisms like Large Initial ssthresh; improved loss recovery performance through the use of selective acknowledgement and the April 2004 New Reno Modification to the TCP Fast Recovery Algorithm for more effective retransmit.

The core is engineered to be future proof with the most thorough support of the next generation Internet Protocol in the industry.

The Internet has changed the world. And the world is changing the Internet, more specifically, the underlying TCP/IP protocol of the Internet. Version 4 of the Internet Protocol (IPv4), designed more than twenty years ago, has been stretched beyond its limits in scalability, security and manageability. IPv6 was specifically designed by the Internet Engineering Task Force (IETF) to address these issues and offer:

• Extended address space — IP address size increased from 32 bits to 128 bits, providing virtually unlimited addresses
• End-to-end encryption at the network layer for data confidentiality
• Auto-configuration and quality of service support for improved manageability

As leader in the IPv6 community, HP through HP-UX 11i delivers the best implementation of IPv6 with a completeness of solution unmatched by others.

With HP's Web serving products, Internet and intranet web sites operate in high performance and reliability with complete end-to-end Secure Socket Layer (SSL). With these capabilities, you can deliver dynamic content to the web site or keep your secured e-Commerce store always open for e-Business.

The Suite consists of all software products necessary to deploy, manage, and implement mission critical web servers. The suite is comprised of:

HP Zeus Web Server
HP Zeus Web Server is scalable, high performance web server software available, underpinning business-critical solutions for the world's leading hosting, content provider and secure e-commerce companies. Flexible web-based management, extensive integration capabilities, and comprehensive range of features available from commercial server software, combine to provide fully extensible and future-proof web-based solutions for HP-UX 11i.

Network Server Accelerator
The HP-UX 11i Network Server Accelerator for HTTP (NSA HTTP) is a networking feature that improves Web server performance by maintaining an in-kernel cache of recently accessed Web pages.

Across industries, professionals and knowledge workers perform their work away from their desks more than half the time. An IT infrastructure designed primarily to provide services to your employees’ desk is no longer in sync with the business needs. To ensure maximal productivity, you need to provide IT services that follow the users: one where all the business data and applications, computation and communication services follow the users.

Wireless technologies and highly capable mobile devices are important and necessary elements of a Mobile IT Infrastructure but they are not sufficient. A Mobile IT Infrastructure needs to address the following issues.

• identification – how to identify a mobile device in a global context
• transport – how to track and route services to a mobile device
• security – how to ensure the secure delivery of services to a mobile device

With in-depth technical expertise and practical experience with pioneering deployments, HP-UX networking engineers have gained unique insights on these issues. Their know-how and insight are encapsulated in the implementation of the HP-UX 11i Mobility Solutions

The digital media revolution is transforming the enterprise network infrastructure. With demonstrated cost saving and effectiveness in areas such as online training and webcast of executive presentations, enterprises are extending the use of the IP network to carry rich digital audio and visual content. These new rich media applications impose stringent performance and scalability requirements on the infrastructure.

As a technology pioneer in the digital revolution of the entertainment industry participating in all stages of the digital media experience from creation, distribution to consumption, HP has unique expertise and capabilities in meeting these requirements. HP-UX 11i provides not only a robust and scalable platform for applications but also a set of capabilities specifically designed and optimized for the delivery of rich digital media.

HP-UX 11i Internet Express is a collection of the most popular and up-to-date set of Internet and security services and tools, combined with a graphical administration utility for ease of management and easy installation of services and configuration. Included with every HP-UX 11i OE Media Kit, the Open Source software is fully tested and qualified for HP-UX 11i supported HP 9000 and HP Integrity servers.

SCTP is a transport protocol that facilitates reliable transmission of data between two endpoints of an association in an Internet Protocol (IP)-based network. In an IP stack, it exists at a level equivalent to that of Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).

SCTP supports multi-homing, delivery of data in multiple streams, and preservation of message boundaries. It also supports acknowledged, error-free, non-duplicated transfer of data; fragmentation of data to conform to maximum transmission unit (MTU) size; and optional bundling of user messages into an SCTP packet.

SCTP also includes mechanisms such as checksums, sequence numbers, and selective retransmission of data. In addition, it supports congestion control algorithms, SYN flood protection, and error handling.
