A system and method for implementing telephony devices in a distributed network environment is disclosed. The present invention provides for voice transmissions to be given a dedicated virtual local area network ('VLAN') for packet transmission and reception to prevent poor quality of service. Non-voice data packets are transmitted on a separate VLAN.

Method for bring-up of voice over internet protocol telephones

A system and method for implementing telephony devices in a distributed network environment is disclosed. The present invention provides for checking data packets to ensure that non-voice data packets are properly tagged to be transmitted on a native virtual local area network ('VLAN'). Voice data packets transmitted on a separate VLAN with a higher priority.

A data center provides secure handling of HTTPS traffic using backend SSL decryption and encryption in combination with a load balancer such as a content switch. The load balancer detects HTTPS traffic and redirects it to an SSL offloading device for decryption and return to the load balancer. The load balancer then uses the clear text traffic for load balancing purposes before it redirects the traffic back to the SSL offloading device for re-encryption. Thereafter, the re-encrypted traffic is sent to the destination servers in the data center. In one embodiment, the combination with the back-end SSL with an intrusion detection system improves security by performing intrusion detection on the decrypted HTTPS traffic.

A one-arm data center topology routes traffic between internal sub-nets and between a sub-net and an outside network through a common chain of services. The data center topology employs layerservices on a common chassis or platform to provide routing and firewall services while reducing the number of devices necessary to implement the data center and simplifying configuration. Load balancing is provided by a load balancing device. In the one-arm topology, policy based routing or client network address translations or NAT pushes traffic to the CSM.
