Broadcom targets 10 Gbps Ethernet backhaul for LTE

Broadcom says its newest switch for mobile backhaul addresses skyrocketing mobile data traffic via a single-chip solution that delivers 10 Gbps Ethernet to LTE networks.

The StrataXGS BCM56450 switch integrates high-bandwidth switching with a control-plane processor, hierarchical traffic management, packet timing recovery plus advanced operation, administration and maintenance (OAM) functions.

"Given the rise of mobile data traffic, carriers are focused on improving their backhaul strategy to meet end users' evolving needs while offering more services," said Ram Velaga, Broadcom vice president and general manager, core switch. "Today's introduction builds on our established StrataXGS leadership and longstanding innovations in carrier Ethernet to equip carriers with a high-performing foundation that supports their rapidly evolving mobile backhaul needs." 

According to Broadcom, the new switch provides a 40 percent I/O bandwidth increase and integrated 10 Gbps serial interfaces, in addition to more than doubling the forwarding table scale.

The StrataXGS BCM56450 is currently sampling with production slated for 2014's first half.
