Wireless Backhaul

With the introduction of IP Multimedia Subsystem (IMS) and Fixed-Mobile Convergence (FMC) capabilities into the wireless infrastructure, connectivity between network elements is shifting away from ATM in favor of Ethernet/IP.

In order to offer new IP services such as mobile TV and on-demand multimedia while maintaining the connection-oriented paradigm that service providers demand, platforms in the wireless network will need to support carrier Ethernet capabilities.

In many wireless platforms such as Aggregation Nodes, Radio Network Controllers (RNCs) or Base Station Controllers (BSCs), processing and interface cards within the system are interconnected through GbE links on the backplane.

With its robust VLAN capabilities, comprehensive traffic management, and protection mechanisms, the Brooklyn-10 Carrier Ethernet Switch is an ideal solution for wireless backhaul applications.

Boasting 4K VLANs per port, the Brooklyn-10 supports an order of magnitude more VLANs than supported by a nominally equivalent, enterprise-class Ethernet switch. It supports functions like IGMP and PIM snooping, which are required for mobile TV applications.

Network uplinks are either through the ports on the switch card or a dedicated uplink card. With its SPI4.2 interface, the Brooklyn-10 can support E-LINE and E-LAN services over both Ethernet and SONET/SDH uplinks on the switch card. In addition, the Brooklyn-10 provides flexible transport features so that a wireless backhaul platform can be integrated into either a PEB/PBB/PBB-TE or T-MPLS network.
