FP2: 1x16G的FPE（Chipset)， 1x16G

FPC3：2个20G的PFE（Chipset），2x20G

T640-FPC4-ES:  1个50G的PFE（Chipset)， 1x50G

T1600-FPC4-ES：2个50G的PFE（chipset)，2x50G

由此预测未来的FP5：

T1600-FPC5：1个FPE，1x120G,

T4000-FPC5：2个PFE，2x120G

T640路由结点和TX矩阵体系架构

http://www.juniper.net/techpubs/en_US/release-independent/junos/topics/concept/sib-t640-description.html

由于每个第 3 类 FPC 支持 2 个 PFE，一个 T640 路由节点有 8 个 FPC 插槽，因此一个完全配置的
T640 路由节点包含 16 个 PFE。每个 PFE 能够支持相当于2xOC-192/STM-64 接口的带宽。

Each Type 1 FPC and Type 2 FPC has a dedicated ASIC with five high-speed links that connect to the SIBs (one link per SIB). Each Type 3 FPC has two dedicated ASICs, and each ASIC has five high-speed links that connect to the SIBs (a total of 10 links). Each Type 4 FPC has one dedicated ASIC with ten high-speed links that connect to the SIBs (two links per SIB). One of the five SIBs—usually SIB4—acts as a backup to the remaining four SIBs. If a SIB fails, the backup SIB becomes active and traffic forwarding continues without any degradation. When the failed SIB is replaced, it becomes the new backup.

The T640 routing node supports the following types of FPCs:
■ Enhanced Scaling FPC1—Rated at 4 Gbps full duplex
■  FPC2, Enhanced II FPC2, and Enhanced Scaling FPC2—Rated at 16 Gbps full duplex
■ FPC3, Enhanced II FPC3, and Enhanced Scaling FPC3—Rated at 40 Gbps full duplex
■ T640 Enhanced Scaling FPC4 and T640 Enhanced Scaling FPC4-1P—Rated at  50 Gbps full duplex; supports one PIC.

    传闻是T1600-FPC5：1个FPE，1×100G

  2. 理客 于 2010-09-07 12:17 上午

    也可能是POS时100G，而以太时120G

  3. ilovebgp4 于 2010-09-08 4:09 上午

    POS会有100G标准吗？据说40G以上只剩以太网了

  4. 理客 于 2010-09-08 6:47 上午

    这里指的是100G的能力，不是接口

    T4000-FPC5之250G的出处：
    Juniper Networks Inc. (NYSE: JNPR) came out today saying it’s upgrading its T series to 250 Gbit/s per slot.
    Trial systems with the fabric should arrive later this year, with real sales to start in 2011.

    Each T640-FPC4-ES has one Packet Forwarding Engine
    Each T640-FPC4-1P-ES has one Packet Forwarding Engine
    Each T1600-FPC4-ES has two Packet Forwarding Engines
