Blue Coat Technology Expert Examines IPv6 Application Development as IPv6 Adoption Driver

SUNNYVALE, Calif.--(Business Wire)--
Blue Coat Systems, Inc. (Nasdaq:BCSI), the technology leader in Application
Delivery Networking, today announced that its senior architect, Qing Li, has
co-authored with Jinmei Tatuya and Keiichi Shima two new derivative reference
books on Internet Protocol version six (IPv6) core protocols, IPv6 Socket API
Extensions: Programmer's Guide and Mobile IPv6: Protocols & Implementation,
recently published by Morgan Kaufmann.

"As networks become increasingly IPv6-ready, attention has shifted to developing
the applications and mobility support for those networks," said Qing Li, IPv6
technology leader at Blue Coat addressing his two newly published reference
books on IPv6 technology development. "While both IPv6 and IPv4 co-exist, there
will be a transition period that will require unique tools to guarantee
uninterrupted application delivery over local networks, mobile networks and the
Internet. Application and software developers should be aware of the transition
issues and make conscious design decisions that can assist in the successful
migration to IPv6."

In the first new book, IPv6 Socket API Extensions: Programmer's Guide, Qing and
his co-authors illustrate how to write portable applications that can run on
either IPv4 or IPv6 networks and provides an introduction to the IETF standards
for IPv6 application program interfaces.

"The major operating systems that are used in commercial, business and consumer
environments are now implementing IPv6, acceleratingthe transition from IPv4 to
IPv6. The increased availability of IPv6-specific applications, services and
content will also continue to fuel this transition," said Qing. "During this
period, portable software that can run on both IPv4 and IPv6 networks will be
critical to ensuring business process continuity and success."

The second new reference book, Mobile IPv6: Protocols & Implementation, Qing and
his co-authors examine mobile IPv6 as anenabling technology for multimedia
services and devices worldwide, including cellular systems, multi-access network
handovers, location privacy and enterprise mobile networking.

"With the growing adoption of mobile applications and devices, mobile IPv6 will
be critical to ensuring a successful transition to IPv6," said Qing. "By
maintaining the existing connections through which the mobile device is
communicating while the address changes, mobile IPv6 provides a mechanism that
enables IPv6 devices to communicate seamlessly."

Qing works on the design and development of Blue Coat application delivery
network technologies, including IPv6 implementations. In addition, to his most
recent books, Qing has co-authored a prominent two-volume reference series on
IPv6, IPv6 Core Protocols Implementation and IPv6 Advanced Protocols
Implementation.

In June, at Interop Tokyo, Blue Coat demonstrated a secure migration path for
applications and services from IPv4 to IPv6. With an intelligent IPv6 proxy
appliance acting as an intermediary, the retrieval of applications, services and
data in either an IPv4 or IPv6 environment is transparent to the users. This
migration strategy will ensure business process continuity without the
complications associated with address translations, rewriting applications or
upgrading the underlying network infrastructure.
