STATEFUL. The Netopia Gateway monitors and maintains the state of any
network transaction. In terms of network request-and-reply, state consists of
the source IP address, destination IP address, communication ports, and
data sequence. The Netopia Gateway processes the stream of a network
conversation, rather than just individual packets. It verifies that packets are
sent from and received by the proper IP addresses along the proper commu-
nication ports in the correct order and that no imposter packets interrupt
the packet flow. Packet filtering monitors only the ports involved, while the
Netopia Gateway analyzes the continuous conversation stream, preventing
session hijacking and denial of service attacks.
static route. Route entered manually in a routing table.
subnet mask. A 32-bit address mask that identifies which bits of an IP
address represent network address information and which bits represent
node identifier information.
synchronous communication. Method of data communication requiring
the transmission of timing signals to keep peers synchronized in sending
and receiving blocks of data.
-----T-----
telnet. IP protocol that lets a user on one host establish and use a virtual
terminal connection to a remote host.
TR-064. TR-064 is a LAN-side DSL Gateway configuration specification; an
extension of UPnP. It defines more services to locally manage a Gateway.
TR-069. TR-069 is a WAN-side DSL Gateway Management specification; pro-
vides services similar to UPnP and TR-064. The communication between a
Gateway and management agent in UPnP and TR-064 is strictly over the
LAN, whereas the communication in TR-069 is over the WAN link for some
features and over the LAN for others. TR-069 allows a remote Auto-Config
Server to provision and manage a Gateway.
twisted pair. Cable consisting of two copper strands twisted around each
other. The twisting provides protection against electromagnetic interference.
