InChorus Application Front-End Switch
Leading a new generation of Web switches, Asce Networks' award-winning InChorus products are integrated services front-ends. Built on an innovative http://www.ascenetworks.com/product/image/asce_webswitch1.gifdistributed processing architecture, InChorus products support all Web OS Internet traffic control services.

Key Benefits
Leading a new generation of Web switches, Asce Networks' award-winning InChorus products provide a broad range of high-speed traffic management functions. Built on an innovative distributed processing architecture, InChorus products support Asce Networks' Web OS Internet traffic control services.
The InChorus delivers simultaneous support for Layer 2, 3 and 4 through 7 switching. Unlike traditional packet switches, the InChorus combines a unique collection of traffic management services within a high-performance Ethernet switch - optimized for switching hundreds of thousands of Web sessions every second. Local and global server load balancing, application acceleration, Secure Sockets Layer (SSL) acceleration, URL-based redirection and load balancing and advanced TCP/IP filtering functions are all performed in one application front-end switch.

Global Server Load Balancing

TOP

Global server load balancing allows mirrored servers or server farms to be distributed around the world, enabling requests to be directed to the best site. The application front-end switches determine the best site based on server health, proximity to the client and server response time. The application front-end switches automatically exchange this information with all other application front-end switches. With a global view of every site's health and performance, each application front-end switches develops a list of the best performing sites. The switches then direct traffic to sites in proportion to the sites' performance measurements. As a result, the best performing sites receive more connections than others, according to their ability to handle more connections.

High Performance Server Load Balancing
Server load balancing on the InChorus enables virtually unbounded server capacity. Unlike competing server load balancing products built around a single, central processor, the InChorus employs powerful I/O processors on each of its network interface ports. The InChorus can switch Web sessions at blazing speeds--up to 180,000 L7 sessions per second can be delivered.

Flexible Groupings of Applications and Servers
The InChorus provides Virtual IP (VIP) addresses to represent the target servers and applications, assigning each session to the most available server associated with the destination VIP specified in the session request packet. It monitors each session from start to finish, providing full address translation as it forwards packets between the client and server. VIPs can be administered in blocks, allowing virtually unlimited numbers of virtual addresses while making administration fast, simple and error-free.

Simple, Effective Load-Balancing Algorithms
System managers can configure the load-balancing method -- round-robin, least-connections, hashing or minimum misses. Maximum connection thresholds and different weightings can be assigned to servers to avoid overloading any server. Any server can be designated as a backup or overflow server for another server or server group, further insuring application availability.

Content-Awareness
New URL-based Web cache redirection and server load balancing optimizes cache server farms and Web farms by sending requests with specific URLs or URL "sub-string" matches to designated cache or Web servers.

Secure Sockets Layer Load Balancing
Secure Socket Layer (SSL)-based load balancing optimizes SSL sessions and ensures session persistency - allowing users to continue to re-establish secure connections to a particular server. SSL session IDs can be selected for persistence in SSL/HTTPS load balancing.

Flexible Filtering
Filtering on the InChorus delivers unprecedented levels of network traffic control. Administrators can forward, drop or redirect packets based on application type, protocol and IP source and destination addresses.

Policy-Based Application Redirection
Policy-based redirection and load balancing allows network managers to use powerful filtering rules to intercept traffic for any device and redirect it to a group of the same type of devices, such as firewalls or routers. Application redirection also enables the use of transparent caches and firewalls in clusters to enable scaling of Web sites.

IP Switching and Cisco EtherChannel Trunking
For complete topological flexibility, servers in a load sharing server group, as well as backup and overflow servers, can be located anywhere in a routed network, even across a WAN. IP switching also simplifies configuration and increases security by allowing load-balanced servers to use private IP addresses while the public accesses them through different virtual IP addresses. The InChorus supports EtherChannel-compatible trunks enabling seamless trunking to Cisco routers and switches while balancing across the group at both Layer 2 and 3 to optimize the use of all links.

High Availability
All InChorus application front-end protect applications against failure of a server link, switch port or switch, with sub-second detection and failover. The InChorus constantly monitors server, application and content availability, bypassing unhealthy servers when it distributes new sessions and automatically re-enrolling them upon service restoration. Intelligent application health checking ensures integrity of the entire data path. ASCE Networks' InChorus can also be deployed in active-active and active-standby redundancy configurations. Based on the GlusterNG N+M, the InChorus can support multi-node active and simultaneous operation of Layer 3 interfaces and Layer 4 services across switches.

Bandwidth Management and QoS
With ASCE Networks' InChorus users can meter, control and account for bandwidth use - by client, server farm, virtual service, application, user class, content type and many other traffic classes - using a variety of Layer 2 through 7 attributes. Bandwidth policies composed of three bandwidth rates can be assigned to each traffic classification. These rates include a Committed Information Rate which is the guaranteed minimum bandwidth, a Soft Limit which is the metered rate used when bandwidth is available, and a Hard Limit which is the maximum burst rate.

Adaptive Network Management
All InChorus application front-end switch functions can be fully managed and configured via any Web browser, SNMP management application or through a command line interface--accessible via remote access, serial,SSH2 or Telnet connection, with full password protection.
