Cisco has started the next phase of its Borderless Networks
initiative, whose purpose is to make computing seamless regardless
of location or platform, with new product and feature announcements
for Medianet, Energywise, and Trustsec.
Supporting the initiative enhancements are new switches and
Integrated Services Routers. Love or hate Cisco, the company has a
plan, articulates it well, and delivers. Any infrastructure vendor
that wants to compete with Cisco is going to have to step up.
It's no secret that Cisco is getting into real-time media in a
big way from streaming video and video conferencing, to unified
communications and VoIP. Part of the difficulty for IT is building
and managing the network to support real-time services that ride
along with all the other data.
One pain point is identifying end devices and setting QoS
parameters needed to deliver real-time media end to end.
Cisco is expanding Medianet to support the discovery of endpoint
devices whether they are VoIP phones, camera, or displays. The
discovery mechanism not only identifies the media endpoint, but the
media properties like video or audio resolution and relates that to
bandwidth, delay, and jitter requirements.
Based on the discovery, Medianet can set QoS parameters through
the network, ensuring that the device can receive and display media
properly. It's automated management that goes beyond what
standards-based discovery mechanisms like the IEEE Link Layer
Discovery Protocol (LLDP) and Link Layer Discovery Protocol-Media
Endpoint Detection (LLDP-MED), which Eric Krapf describes in
LLDP-MED: Learning About the Endpoint, currently offer.
At present, Medianet only discovers the display and media
details from Cisco devices, but the company says it will release an
API for third-party vendors to support the discovery capabilities
in the other devices.
