important as enterprise (primarily frame-based) and service provider (primarily
cell-based) networks move closer together.
Infrastructure Connectivity
The second key element of the architecture is Infrastructure Connectivity.
IntraCore specifies standards based, high performance, cost effective
technologies for connectivity among devices in the network.
In the LAN –
At the network edge, Layer 2 switched 10/100/1000 Ethernet meets the
requirements for high-speed connectivity of desktop computers and scalable,
cost effective data transmission for trunks to the network core.
In the network core, Layer 2/3+-switched 10/100/1000 Ethernet meets the
requirements for high speed, scalable, cost effective data transmission and
support for all multi-service data types. High performance servers can be
centrally located for added physical security.
Throughout the LAN, advanced queuing techniques combined with multiple
priority levels and support for industry standard 802.1Q and 802.1p enable
Quality of Service within the network.
In the MAN/WAN –
Long haul Gigabit Ethernet, ATM, and Packet over SONET meet the
requirements for all of the following:
❑
scalable, cost effective data transmission
❑
support for all multi-service data types
❑
service provider inter operability
Network Management, Security, Performance, and
Control
IntraCore includes a rich suite of features required for the effective
management, security, performance and control of the network. The following
table illustrates the features and standards supported as part of this section of
the overall architecture.
