Application Performance

Microsoft Windows Server 2008 gives 

organizations a powerful new platform that 

is designed to power the next-generation of 

networks, applications, and Web services. 

Windows Server 2008 includes some exciting 

new components such as Microsoft’s new 

TCP/IP stack, Secure Socket Tunneling Protocol 

(SSTP), and new versions of industry standard 

applications like Windows Terminal Services 

and Internet Information Services.  F5 has been 

working closely with Microsoft to ensure that 

F5’s Application Ready Network for Microsoft 

Windows Server 2008 provides the highest level 

of application availability, performance, and end 

user satisfaction.

One of the highlights of Microsoft Windows 

Server 2008 is a next generation TCP/IP stack 

that has been completely redesigned from 

the ground up. F5 solutions include a host 

of TCP/IP optimization technologies that are 

compatible with Microsoft’s new stack. These 

optimizations, which combine session-level 

application awareness, persistent tunnels, 

selective acknowledgements, error correction, 

and optimized TCP windows, enable F5 devices 

and Microsoft Server 2008 installations to fully 

utilize available bandwidth. This enables F5 

devices to adapt, in real time, to the latency, 

packet loss, and congestion characteristics 

of WAN links, and accelerate virtually all 

application traffi c. And F5 isolates, controls, 

and independently optimizes user and server 

connections, enabling both the server and end 

user to maximize productivity. 

With the rapid expansion of the Internet 

and the quickly diminishing number of IPv4 

addresses available, organizations are looking 

to ensure their network infrastructure is 

adequately prepared for the future. Internet 

Protocol version 6 (IPv6) support is no longer 

a luxury, it is a necessity. IPv6, a new suite 

of standard protocols for the network layer 

of the Internet, is built into both Windows 

Server 2008, as well as F5 devices, ensuring 

that your network and Microsoft applications 

are ready for this inevitable change.  With 

F5’s IPv6 support, organizations have a clear 

strategy for staging network migration as IPv6 

traffi c grows, without wholesale network and 

application upgrades. Additionally, F5 devices 

can perform IPv6/IPv4 translation, translating 

traffi c for consumption by either IPv4 or IPv6 

end points. This allows organizations to stage 

their migration gradually as demand for IPv6 

increases. F5 enables you to freely intermingle 

IPv4 and IPv6 services on Windows Server 

2008; for example, F5 can serve as an IPv4 

front end to Windows Server 2008 Web 

Access servers that only use IPv6. With F5, 

organizations have a strong solution for today 

and well into the future.

Windows Server 2008 is extremely effective 

at what it was designed to do: provide a solid 

foundation for server workload and application 

requirements. One of F5’s core strengths is the 

ability to enhance end-user experience while 

increasing application and server performance.  

We do this by taking on many of the duties 

that servers traditionally have to perform. If 

each server has to carry out processor-intensive 

tasks such as compression, caching, and SSL 

processing and certifi cate management, the 

amount of processing power these devices 

have left to perform core tasks is reduced. 

By offl oading these types of tasks onto F5’s 

centralized and high powered network devices, 

F5 greatly improves Windows Server 2008 

server effi ciency and enables organizations to 

reduce the amount of hardware. This applies to 

all the major components of Windows Server 

2008, including Windows Terminal Services, 

Internet Information Servers, and SSTP.

F5 provides technology that guarantees the 

most effi cient network possible. Because 

F5’s unique TMOS™ operating system is a 

full proxy, it can optimize any end point that 

connects through the system. As a full broker 

of communications, the system optimizes 

communication for every single end-device 

communicating through it. This optimization 

can take place up and down the entire stack 

— from the transport layer to the protocol 

and application layer — functions outside the 

control of Windows Server 2008. This takes 

the workload off of the Windows Server 2008 

devices for increased server effi ciency. By 

reducing unnecessary protocol communication 

across the network, F5 improves application 

response times and utilization for Windows 

Server 2008 deployments and other 

applications on the network.

Even high-powered and effi cient applications 

and servers, like Windows Server 2008, as well 

as other devices on the local area network 

(LAN), are not much help over the wide area 

network (WAN). Network latency across the 

WAN is one of the biggest challenges facing 

IT departments around the world, and is a 

major concern for organizations deploying 

applications like Windows Terminal Services 

where users can access applications from 

anywhere. Simply increasing bandwidth 

does nothing to solve the problem. F5 helps 

drastically reduce the impact of latency in a 

number of ways. In addition to the benefi ts 

from TMOS, F5 solves latency problems with a 

group of capabilities that eliminates the need 

for the browser to download repetitive or 

duplicate data, as well as ensuring the best use 

of bandwidth by controlling browser behavior. 

By reducing the extra conditional requests 

and excess data (re)transmitted between the 

“Windows Server is one of 
the most popular application 
platforms that we see within 
our enterprise customer 
base. As such, F5 has put 
substantial resources into 
testing its application delivery 
portfolio with the Windows 
Server platform technologies 
through every step of the 
beta to maintain a high level 
of interoperability.”
