Oracle today announced that it has entered into an agreement to acquire Acme Packet, a provider of session border control technology for approximately $2.1 billion.

Acme Packet enables the delivery of voice, data and unified communications services and applications across IP networks. The company's solutions are deployed by more than 1,900 service providers and enterprises globally.

"The proposed acquisition of Acme Packet is another important piece in Oracle's overall strategy to deliver integrated best-in-class products that address critical customer requirements in key industries," said Oracle President Mark Hurd. "The addition of Acme Packet to Oracle's leading communications portfolio will enable service providers and enterprises to deliver innovative solutions that will change the way we interact, conduct commerce, deliver healthcare, secure our homes, and much more."

The combination of Oracle and Acme Packet is expected to accelerate the migration to all-IP networks by enabling secure communications from any device, across any network.

The Board of Directors of Acme Packet has unanimously approved the transaction, which is expected to close in the first half of 2013, subject to Acme Packet stockholder approval, certain regulatory approvals and other customary closing conditions.
