Optimizing AlphaServer Performance with New Gigabit & Layer 4+ Switching Technologies
Topic Area:
Track: Enterprise Solutions
Topic: Networks
Type:  Breakout Session

Schedule:
11/08/99   04:30 PM     Duration: 90 Min.     Room: 10

Presenter:
Dr. Shirish Sathaye
Vice President of Engineering, Alteon Networks, Inc.  

Abstract:
The advent of Gigabit speed networks has put added pressure on host systems to perform. The sheer volume of CPU interrupts can overwhelm servers by consuming valuable CPU cycles normally devoted to processing applications data. As a result, the boost in network speed is negated by lack of system througput. Additionally, scaling host CPU and application performance and optimizing the network-to-server connections has become key issues in maximizing the overall network computing environment. This session will focus on new technologies that have been developed to address these problems and ways in which these technologies can (and are) being deployed. Dr. Sathaye will detail advance adapter technology for Compaq AlphaSystems, such as extended Ethernet frame sizes, interrupt coalesence and other CPU offloading techniques that can be used within the system to improve overall network/system performance. Dr. Sathaye will also provide an overview on new technologies such as Layer 4+ switching that are being used to better manage IP traffic flows and scale CPU and application performance. Dr. Sathaye will discuss the need for tighter integration between server switches and host systems and outline what is being done to optimize connectivity. Finally, Dr. Sathaye will discuss the growing trend toward collapsing IP traffic management functions into high-performance switches that front end host systems -- answering questions such as: Why is this necessary? What is the benefit? How can I better control IP traffic flows to host systems?

Objectives:
Focus on new technologies
 
How Layer 4+ better manages IP traffic flow
 
Understand the growing trend toward collapsing IP traffic management functions into hi-performance switches.
