Ethernet Circuit

Ethernet Circuit Concepts Circuit switching features –End to end quality of service –End to end Layer 2 security –Granular bandwidth Kilobit to Gigabit bandwidth scalability Ultimate flexibility Flexible variety of optical interfaces options Ethernet simplicity of operation and management

Ethernet Circuit Circuit like parameters per Flow (SLA) –Allowed bandwidth –Defined Class of Service –Electrical signal based security (VLAN and MPLS) –Layer 2 VPN End to end solution –Same Ethernet from NIC to NIC –Tag/Label concept (like ATM header)

Rate Limit Concepts Time Packet Rate Setup Rate Transmitted by user Dropped Packets Actual Transmission by switch

Rate Limit Rate limit per Ethernet Circuit –By port –By IP –By TCP/UDP port Tens of Kilobit level increments Performed in the switch at the access level Setup rate 10K 20K 30K 40K 50K 60K 100Mbps

Classification Concepts Class of service based on DiffServ protocol Priority marking based on ToS field Per Circuit Classification –By port –By IP –By TCP/UDP port

Classification Up to 8 classes of service Scheduling based on Strict Priority or Weighted Round Robin algorithms End-to-end classification across the network Classification is performed by the switch in the access port

Security Concepts Security in Layer 2 across the network VLAN based traffic separation Layer-2 VPN with MPLS in the OSM Router End-to-end Ethernet circuit security scheme OptiSwitch

Security IP Intrusion Control –Port/MAC/IP Table look up for intrusion prevention –Unauthorized user can not access the network without the proper parameters Management VLAN prevents access of the switch management through the access port User/Password challenge for SNMP access Optional IPSec Encryption of management traffic

Optical Access Low cost high speed Internet Access circuit High Quality Multicast circuit High Quality Voice virtual circuit OptiSwitch
