Firewall & Load-Balancer: Perfect Union?

February 7, 2000


Leveraging the Network Element Control Protocol
It's not surprising to see so many new technologies and products emerging from within the Web arena. The Web has proven to be the single most profound change to commerce since the credit card. And an e-commerce site needs more than a simple Web server: It requires back-end databases, Layer 4 switches, Web caches, caching services, firewalls and Web content-management solutions. Until now, any methods to make these pieces all work together have been proprietary. Enter the Network Element Control Protocol (NECP).

Out of the gate, NECP is equipped to tackle the communication of servers--Web servers, for example--with Layer 4 switches and Web caches. Maintaining server availability has involved service checks, pings or SNMP traps from the load-balancer to the server. With NECP, a server can tell a load-balancer to give it more traffic, slow down or take it out of the server rotation. The protocol is extendable and capable of handling other duties as well. In these days of stiff competition, it's good to see multiple vendors working together on open standards.

NECP is the spawn of a partnership of market leaders including Alteon WebSystems, F5 Networks, Foundry Networks, Inktome, Network Appliance, Novell and RadWare. It may prove to be successful at alleviating the configuration woes faced by many Web and network administrators. For more information on NECP, visit www.netapp.com/necp.
