The 34-year-old was offered a deal following promotion from League One and has now committed his future ahead of the Cherries' return to pre-season training.
"I'm really pleased. It's been going on over the summer but there was never any doubt I wasn't going to sign," he told the club's official website.
"I love it here and I've felt at home ever since I came here. There's a great set of lads, the staff are fantastic and the manager has been brilliant with me, so I'm delighted to be here and hopefully I can stay for a number of years.
"When you see the way the club is going, it's really exciting and everyone wants to be part of that."
