EZchip公布更多200G网络处理器细节

网络处理器专业厂商EZchip公司公布了其下一代NP-5处理器的细节。NP-5网络处理器（NPU）处理能力将为200G，内置200G的流量管理单元，这将有效降低交换机/路由器的10GE, 40GE和100GE线卡的密度。同时正在设计中的NP-5将为现在使用NP-4 100G芯片的用户提供升级路径，代码后向兼容NP-4，由此在很少软件工作量的情况下客户可以将线卡的带宽和端口密度翻倍。

NP-4采用55nm工艺，计划于2011年下半年进入量产阶段。NP-5将采用28nm工艺，计划于2012年底推出样片。

EZchip公司将在Linley Tech于6月7-8号在美国加州举办的运营商大会上介绍NP-5。

NP-5的主要特性包括:

• 200-Gigabit programmable packet processing
• Integrated 200-Gigabit hierarchical traffic management
• Ethernet ports with integrated MACs supporting 48×10-Gigabit / 12 x 40-Gigabit / 4×100-Gigabit interfaces or combinations thereof
• Enhanced memory management for lookup tables, packet buffering and statistics, all using commodity DDR3 devices for minimized cost and power
• Integrated fabric adaptor for interfacing to Ethernet-based switch-fabrics and 10GBase-KR links for direct connection to the system’s backplane
• Power management for minimizing line card and system power dissipation
• Enhanced support for video streams and IPTV
• On-chip control CPU for host CPU offload
• Operations, Administration and Management (OAM) processing offload
• Synchronous Ethernet and IEEE1588v2 offload for Circuit Emulation Services
• IP reassembly for advanced packet processing offload
