Overview

Cisco Unified Border Element (CUBE)

Cisco Unified Border Element (CUBE) is an integrated Cisco IOS enterprise session border controller (SBC) feature set facilitating connectivity between independent unified communications, voice over IP (VoIP), and video networks.

Session border controllers (SBCs), such as Cisco CUBE, manipulate IP communications signaling and media streams, providing a variety of functions including:

• Security - SBCs protect against Denial of Service (DoS) and Distributed DoS (DDoS) attacks, safeguard against toll fraud and service theft, and provide media and signaling encryption to ensure confidentiality and protect against impersonation/masquerade
• Multivendor interoperability - SBCs normalize SIP (Session Initiation Protocol) signaling stream headers and messages to mitigate multivendor incompatibilities
• Protocol interworking - SBCs enable interworking  between different protocols  or capabilities such as H.323-SIP interworking, SIP normalization, DTMF type conversion, payload type conversion, IPv4-IPv6 interworking, transcoding.
• Quality of Service (QoS) - SBCs enforce call admission control (CAC) policies, type of service (ToS) marking, or rate limiting for service quality assurance
• Session routing - SBCs route sessions across network interfaces to ensure high availability or enable least cost routing (LCR)

VSM and CUBE System Health

VSM collects and stores configuration, capacity and availability information relating to the consumption of all essential CUBE resources. This data is mined at all levels.It stores this information for reporting, trending and analytical purposes. VSM specifically targets critical areas in Cisco CUBE that indicate business-impacting issues.

1. If any changes are made to the architecture, the dashboard will automatically reconfigure itself to measure and display critical capacity data based on the current configuration.

 Items monitored include not only server processor, but also essential aspects of the configuration which have their own specific requirements and capacity limitations. This information is presented by way of several different dashboards within Service Desk.
The purpose of the dashboards is three-fold:The Cisco CUBE System health dashlet allows you monitor general system health, Network connectivity, Network Interface, Dial-peers and Call Legs.
