Interlaken is a scalable protocol that enables chip-to-chip packet transfers at rates from 10 Gbps to 100 Gbps and beyond. Altera’s Interlaken intellectual property (IP) core continues to scale with today’s demand for more bandwidth and higher performance needs. Altera has been a part of the Interlaken Alliance since its inception in 2007 and continues to innovate new protocol features to provide customers with robust and easy-to-implement Interlaken IP solutions. Altera entered the market with 25G Interlaken IP cores and now offers 200G+ Interlaken IP cores.
Brocade Integrates and Qualifies Altera's 120G and 150G Interlaken IP
|“Altera’s Interlaken IP delivers the bandwidth scalability and data efficiency our customers require not only for big data, but also for other applications that require high-rate data transfers through the network.”|
Majid Afshar, Vice President of ASIC and Hardware Engineering, Brocade
Altera's Interlaken IP provided Brocade a favorable IP strategy enabling them to simply reconfigure the IP for their various line module configurations. This uniqueness enables Brocade to offer their customers the options to choose the right level of services given certain budget constraints. The combination of Altera’s Interlaken IP core in the Stratix® V FPGA with Brocade's router innovations eliminates the bottlenecks to scale cloud-optimized networks. This allows businesses to manage high volumes of big data and other applications that require high-rate data transfers through the network.
Altera's Interlaken IP core is ideal for multi-terabit routers and switches for access, carrier Ethernet, and data center applications that demand high IP configurability to optimize for system performance and scalability.

Altera's Interlaken IP Solution
The Interlaken IP core includes Altera’s technology-leading transceivers: physical medium attachment (PMA), physical coding sublayer (PCS), and media access control (MAC) layers. The PCS and PMA layers are hardened within the Stratix V and Arria® V FPGAs, thereby saving customers 30 percent to 50 percent of FPGA logic resources. In addition to resource savings, the Interlaken IP has been through extensive simulation verification and has been proven to work on multiple internal and customer platforms. Altera's Interlaken IP solution has passed the Interlaken Alliance's device interoperability tests. Altera continues to set up interoperability activities with leading ASSP vendors for next-generation platforms.
