BCM56457B1IFSBG - 100 Gbps Integrated Multilayer Ethernet Switch and Traffic Manager

Product Description

BCM56457B1IFSBG is purpose-built for nextgeneration Carrier Ethernet EAdvance Data Sheetdge and Mobile Backhaul platforms. It combines a feature-rich packet processing engine, integrated hierarchical traffic manager, deep external packet buffer, address management, and a non-blocking switch fabric into a single 40 nm CMOS device. The BCM56457 supports an integrated packet buffer with an external packet buffer expansion option, utilizing economical DDR3 SDRAM technology.

Product Features

Integrated 2.0 MB packet buffer

Support for up to 720 MB of external packet buffer using six DDR3 SDRAMs

Integrated hierarchical traffic manager supporting:

– Four-level hierarchical scheduler

– Min/Max rate guarantees at each scheduling level

MEF-compliant hierarchical metering with 8 Kbps granularity

Supports VLAN translation in both ingress and egress

Supports Multi-protocol Label Switching (MPLS) for L2 VPLS/VPWS and L3 MPLS services

Supports port trunking and mirroring across stack

Supports advanced packet flow control: Head of Line (HOL) blocking prevention, back pressure

Supports packet classification using IEEE 802.1p QoS or DiffServ/TOS priority

Low power 40 nm CMOS process

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.
