摘要： 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 layer 4 services 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.

摘要： An architecture, arrangement, system, and method for or controlling traffic flow into and out of a server farm having active-active stateful devices. A symmetric Gateway Load Balancing Protocol (sGLBP) eliminates asymmetric traffic flow for out-bound traffic. Load distribution for in-bound traffic is balanced between a redundant pair of aggregation switches using either static host routes, Route Health Injection or in a more general manner, with external routes with a mask longer than the connected subnet advertised by the routing protocol. The return traffic is symmetric because it returns through the same aggregation switch that it came from. Similarly, traffic originating from a server farm exits from one of the redundant aggregation switches and returns from the same aggregation switch.

摘要： 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.

摘要： An intrusion detection system (IDS) is capable of identifying the source of traffic, filtering the traffic to classify it as either safe or suspect and then applying sophisticated detection techniques such as stateful pattern recognition, protocol parsing, heuristic detection or anomaly detection either singularly or in combination based on the traffic type. In a network environment, each traffic source is provided with at least one IDS sensor that is dedicated to monitoring a specific type of traffic such as RPC, HTTP, SMTP, DNS, or others. Traffic from each traffic source is filtered to remove known safe traffic to improve efficiency and increase accuracy by keeping each IDS sensor focused on a specific traffic type.
摘要翻译：入侵检测系统（IDS）能够识别流量来源，过滤流量以将其分类为安全或可疑，然后应用复杂的检测技术，例如状态模式识别，协议解析，启发式检测或异常检测，单独或异常检测基于流量类型组合。在网络环境中，每个流量源都提供至少一个专用于监视特定类型的流量（如RPC，HTTP，SMTP，DNS或其他）的IDS传感器。过滤每个流量来源的流量，以清除已知的安全流量，从而通过将每个IDS传感器集中在特定流量类型上来提高效率并提高准确性。
