Please see the data sheet specifications here. It states:
• The Cisco 3800 Series Module (AIM-VPN/SSL-3) can provide hardware-based IPSec encryption services of 160 and 185 Mbps in the Cisco 3825 and 190 and 210 Mbps in the Cisco 3845 (IPSec IMIX and 1400-byte packets).
1IPSec numbers are maximum values based on the Spirent IPSec IMIX definition and 1400-byte packet size. Each test is performed with a single tunnel. Customers are urged to consult with the Cisco account team and review all Cisco VPN solution design guides for greater detail on deployment options and scaling. Cisco recommends IPsec user to also review the Cisco Solution Design Guides for more specific information on scaling http://www.cisco.com/application/pdf/en/us/guest/netsol/ns171/c649/ccmigration_09186a008075ea98.pdf and
Well, services offered vary widely according to your local service providers. Here in USA, for instance, data center or Metro Ethernet services to offices are typically provisioned over Gigabit Ethernet facilities (interfaces) with some portion of that guaranteed and tarriffed (charged) for the level of service (throughput) guaranteed for your connection.
If the IPsec "throughput" (i.e. customer observed data rate between end hosts) needs to be 155 Mbps, then yes the service between offices must be some number greater - accounting for the encapsulation, signalling etc. You could figure it out mathematically but most customers would just order the tier of service that gives one some room for growth. So, for instance if by pure calculation you decide you need, say, 180 Mbps then just order 200 Mbps (or next available service tier).
