OC-192 is roughly 10Gbits per second. That's 10Mbits per millisecond. 3x10Mbit per millisecond = 30Mbit in 3 milliseconds 5x10Mbit per millisecond = 50Mbit in 5 milliseconds I don't know SONET MTUs, but Google says 4470 bytes, which is 35760 bits. 10 x interface MTU is 358kbits. Does that answer your question? Matthew Walster _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
