There are presently two ways that BACnet can be “spoken” over the public network, and
these two methods are prescribed in the BACnet standard in Annex H and Annex J
(BACnet/IP). For Annex H communication, a BACnet message destined for a remote
BACnet network that must traverse a public network is sent by a tunneling mechanism.
Introduction to Gaia Advanced Routing
Dynamic Routing is fully integrated into the WebUI and the command-line shell. BGP, OSPF and RIP are supported. Dynamic Multicast Routing is supported, using PIM (Sparse mode and Dense mode) and IGMP. DHCP Relay
BOOTP/DHCP Relay extends Bootstrap Protocol (BOOTP) and Dynamic Host Configuration Protocol (DHCP) operation across multiple hops in a routed network. In standard BOOTP, all interfaces on a LAN are loaded from a single configuration server on the LAN.
Many of these attacks are now either semiautomatic or completely automatic. In semiauto-
matic DDoS attacks, the intruder typically uses automatic tools to scan and compromise
vulnerable machines and infect these machines with the attack code. At some later time, the
machines with the attack code are used to launch a widely distributed attack. Even more
problematic are the completely automatic attacks, where the need for later communication
with attack machines is bypassed.
In essence, a credit rating reflects a rating agency’s opinion, as of a specific date,
of the creditworthiness of a particular company, security, or obligation. For almost a
century, credit rating agencies have been providing opinions on the creditworthiness of
issuers of securities and their financial obligations. During this time, the importance of
these opinions to investors and other market participants, and the influence of these
opinions on the securities markets, have increased significantly.

Introduction to the SMTP Service
Explain that SMTP is the Internet standard for e-mail message delivery.
Describe how the SMTP service works in IIS, and how the SMTP server
sends and receives e-mail messages. Explain that, if they did not enable the
SMTP service during Microsoft Windows® 2000 installation, they can
enable it by using Add/Remove Programs in Control Panel.

Wireless local area networks
Virtual LANs provide support for workgroups that share the same servers and other resources over the network. A ﬂexible broadcast scope for workgroups is based on Layer 3 (network). This solution uses multicast addressing, mobility support, and the Dynamic Host Conﬁguration Protocol (DHCP) for the IP. The hosts in the network are connected to routers via point-to-point connections. The features used are included in the IPv6 (Internet Protocol version 6) protocol stacks. Security can be achieved by using authentication and encryption mechanisms for the IP....
