| Access layer and core layer switches use redundancy backup mechanism and emphasis the high reliability of whole network. Choosing 4680 as access router and 6508 as core switch is to give prominence to the high-performance and high-stability of the network.
Aggregation layer uses S3524, which support all 1000M ports uplink and downlink, to make sure the bandwidth of users. High rate of taking in and sending out also guarantees the fluency of data transferring, supports cluster technique and high expansibility.
Use 2226 as access layer router, high performance and security, supply L2~L7 ACL which guarantees the safety of the network from access layer. |
