• Manufacturer Part Number: bcm56520
• Description: 108 Gbps Integrated Multilayer Ethernet Switch
• Manufacturer: Broadcom Corp.

The BCM56520 is Broadcom’s seventh generation of the StrataXGS
product line. It is a highly integrated multilayer switch designed to
address new and emerging Enterprise and Metro Area Networking
applications. With a combination of cost-optimized Ethernet
functionality, sophisticated classification, accounting, and Metro
protocols, and advanced services, the BCM56520 makes an ideal
solution for the Enterprise wiring closet as well as Metro fixed access
and edge networks.
The BCM56520 incorporates up to 24 ports of GbE and four ports of
HiGig2™. The four ports of HiGig2 can operate as standard IEEE
802.3ae XAUI™ or as ports running the HiGig2 protocol. Using the
HiGig2 protocol, the BCM56520 can interconnect with other Broadcom
devices for scalable, high-performance fixed, and modular systems.
Building upon the industry-leading XGS architecture, the BCM56520 is
the industry’s first true unified wireless/wireline switch. Supporting the
CAPWAP protocol for access point and mobility domain connectivity,
the BCM56520 enables edge stackable systems to offer the performance
and scalability previously only available on high-end wireless
controllers. With this new paradigm, system vendors can deliver a
seamless, integrated wireless solution with a dramatic reduction in total
solution cost.
The BCM56520 also delivers the most critical emerging technologies in
Metro Area Networking. It features popular protocols such as enhanced

Q-in-Q (802.1ad), MPLS/VPLS, Provider Backbone Bridging
(802.1ah), Provider Backbone Transport (802.1Qay), and VLAN cross-
connect. Built upon a novel virtual port architecture, all of these
protocols may operate simultaneously to satisfy all manner of Metro
deployments.
As service providers deploy carrier Ethernet networks, two underlying
technologies are used for guaranteeing service quality: time
synchronization and OAM. The BCM56520 is architected with a
comprehensive synchronization solution that includes layer-one clock
recovery (G.8261) and hardware support for 1588v2 and 802.1AS. The
highly scalable and flexible BCM56520 OAM solution relieves
application software by handling critical high-bandwidth functions in
hardware.
All devices in the BCM56520 family support a 32-bit PCI interface
running at 66 MHz.
