3DES

An encryption algorithm which utilizes the DES algorithm three times in succession.

ACCM

See Asynchronous Control Character Mask.

application performance

In the fields of information technology and systems management, Application Performance Management (APM) is the monitoring and management of performance and availability of hardware, software applications and networks.

are you there

Any packet (for example, an ARP Request) that produces a response, sent to determine whether the DUT is able to respond.

autonomous system boundary router

ABR located between an OSPF autonomous system and a non-OSPF network. ASBRs run both OSPF and another routing protocol, such as RIP. ASBRs must reside in a nonstub OSPF area.

backbone

Part of a network that acts as the primary path for traffic that is most often sourced from, and destined for, other networks.

Big Data

Big data is a buzzword, or catch-phrase, used to describe a massive volume of both structured and unstructured data that is so large it is difficult to process using traditional database and software techniques. In most enterprise scenarios the volume of data is too big or it moves too fast or it exceeds current processing capacity. Despite these problems, big data has the potential to help companies improve operations and make faster, more intelligent decisions.

border gateway protocol version 4

Interdomain routing protocol that exchanges reachability information with other BGP systems. It is defined by RFC 1163. BGP4 supports CIDR and uses route aggregation mechanisms to reduce the size of routing tables.

challenge handshake authentication protocol

A protocol that runs over LCP and is used to authenticate connections over a PPP connection.
