Linux

• Linux Debugging & Performance (3 Days)

This popular course introduces advance techniques to enable engineers to better profile and tweak their systems. These techniques focus on debugging applications in user mode, and monitoring application performance.

• Linux Kernel advance: Networking Programming (3 Days)

Based on the five days "Linux Kernel Programming" as a prerequisite, this course further discusses specific aspects of network performance.

• Linux Kernel advance: File system (3 Days)

Go deeper into the Linux Kernel - by getting to know the block device and filesystems components. Explaining the block device architecture, including the buffer cache, and what it means to create a block device driver. Detailed discssion of the Virtual Filesystem Switch (VFS) layer.

• Embedded Linux

An add-on to either the ‘Kernel Programming’ course or the ‘Linux Administration’ course, this course focuses on architecture-specific concerns and idiosyncrasies, in maintaining or programming in an embedded Linux environment.

Networking

• AAA (2 Days)

This course focuses on protocols used for Authentication, Authorization and Accounting - commonly referred to as "AAA". Legacy (standalone) authentication mechanisms in both UNIX and Windows are explained, followed by protocols such as Radius, Kerberos, NIS (YP), LDAP and the various flavors of EAP.

• Application Layer Protocols (3 Days)

This course discusses the main application protocols of the Internet: DNS (Domain Name Service), FTP (File Transfer Protocol), E-Mail protocols, HTTP (HyperText Transfer Protocol) and SSL (Secure Socket Layer). In-depth detail is provided down to the packet level with live captures using the WireShark sniffer. Each protocol is examined from both its performance and security aspects.

• IPv6 (2 Days)

IPv6 is the protocol that will eventually inherit "traditional" IP (IPv4) in providing the address space of the future Internet. This seminar discusses IPv6 in depth.

• MPLS (1 Day Seminar)

Dealing with the MultiProtocol Label Switching (MPLS) design and implementation. MPLS along with its supporting protocols (LDP, OSPF-TE and RSVP-TE) are discussed, with actual packet captures analyzed using WireShark.

• Network Layer Protocols (4 Days)

This course discusses the TCP/IP protocol stack - the driving force behind the Internet. Detailed discussions of layer II protocols (primarily Ethernet), the Internet Protocol (IPv4 and IPv6), Internet Control Messaging Protocol (ICMP), and the routing protocols RIPv2 and OSPF. This course also touches on advanced aspects: QoS and Multicasting.

• VoIP (2 Days)

This course introduces the myriad protocols used to convey voice and video over the Internet Protocol. It explains both the legacy H.323 protocol stack and the SIP standard, as well as the RTP protocol common to both. This course also discusses SCCP ("Skinny"), a proprietary protocol used in legacy Cisco IP telephony.

Windows

• Windows Debugging tricks and techniques (4 Days)

In many cases, debugging a program does not involve using a full-fledged debugger - Tools such as process monitor (Windows), top and strace (Linux) can often be successfully used to pinpoint and resolve problems. In some cases, however, a debugger is mandatory. These cases are the ones we cover in this course.

• Windows kernel (4 Days)

Understand the inner workings of the Windows Kernel and its various subsystems, from an architectural perspective, as well as through driver writing.

OS X

• OS X system programming (3-5 Days)

This course covers the architecture of OS X from the ground up. OS X is the operating system behind Apple's Macs, iPhones, and iPads.

• OS X kernel programming (4 Days)

This course picks is a follow-up to "OS X System Programming" course, it delves deeper into aspects of Kernel programming. The course describes the XNU kernel in depth, focusing on its three main components: the Mach core, the BSD API layer and the I/O Kit driver foundation.

Advance Programming, Security

• Multi-Core and Multiprocessing Programming (3 Days)

This course provides knowledge to optimize codes under multi-core and multiprocessing environment. In this course, the students would know how to write threaded programs efficiently, how to fully leverage the CPU, Memory and other resources, how to make the compiler optimized and how to achieve best performance on some specific OS and CPU model.
