public key infrastructure
PKI represents the set of hardware, software, people, policies and
procedures that are required for the creation, management, storage,
distribution, and revocation of public key certificates based on public-key
cryptography.
quality of service
QoS is a term for the set of parameters and their values that determine the
performance of a virtual circuit. A service level is typically described in
terms of network delay, bandwidth, and jitter.
random access memory
A group of memory chips that function as the primary workspace of the
computer. Each byte of storage in the chip can be directly accessed without
regard to the bytes before or after it.
A router is an interface device between two networks, connecting LANs to
LANs or LANs to WANs. It selects the most cost-effective route for moving
data between multiprotocol LANs, making sure that only one route exists
between source and destination devices. Routers make forwarding decisions
based on network layer addresses.
resource reservation protocol is used two ways:
1 RSVP is the process of reserving network and host resources to achieve
a QoS for an application.
2 RSVP is an IP-based protocol that is used for communicating
application QoS requirements to intermediate transit nodes in a network.
RSVP uses a soft-state mechanism to maintain path and reservation-state
information on each node in the reservation path.
service access point
A SAP is a point of communication exchange between an application and the
LLC or between layers of software.
service distribution path
The 5620 SAM uses this term interchangeably with service tunnel.
See SLA.
