Cisco Systems OL-12518-01 manual Scenario 2-Latency Across the GSR Mpls Core, Throughput

Page 25

Chapter 4 FCIP over IP/MPLS Core

Testing Scenarios and Results

Where sustained Gigabit throughput is not required (for example, over an OC-12 or slower WAN link), an MTU of 1500 bytes is adequate. Otherwise, use jumbo frames if possible and set the MTU on the Gigabit Ethernet interface to 2300. Also, set the MTU size on the CPE to 2300 bytes. You also need to consider VPN and MPLS headers when configuring MTU size across the path. The MTU size needs to be configured on all routers and switches, including the CPE in the path. The MTU size of 4700 was configured on all PE and P routers to accommodate VPN and MPLS specific headers.

Selective acknowledgement (SACK) is enabled by default in the FCIP profile and should not be turned off. SACK enables the TCP receiver to identify to the sender the contiguous TCP blocks that have been successfully received. The sender can then selectively retransmit only the missing blocks. Figure 4-12shows the result for the throughput testing of the MTU. A full line rate is achieved with packet sizes larger than 1024.
